 1 Quick Start

This chapter introduces how to build a wireless network using the EAPs and how to complete the basic settings. Follow the steps below:

1.Determine the Management Method

2.Build the Network Topology

3.Log In to the EAP

4.Configure and Manage the EAP

4

1.1 Determine the Management Method

Before building the wireless network, choose a proper method to manage the EAP based

on your actual network situation. Omada EAP supports two configuration option: Controller

Mode or Standalone Mode.

■■Controller Mode

If you want to establish a large-scale wireless network and have mass EAPs to be managed, Controller Mode is recommended. In Controller Mode, all EAPs can be centrally configured and monitored via an Omada Software Controller or an Omada Cloud Controller (OC200).

For detailed instructions about the network topology in such situation and how to use an Omada Software Controller or an OC200, refer to the User Guide of Omada Controller or OC200. To download Omada Software Controller and its User Guide, go to https://www. tp-link.com/en/download/EAP-Controller.html. And the User Guide of OC200 can be downloaded athttps://www.tp-link.com/en/download/OC200.html.

■■Standalone Mode

If you have a relatively small-sized wireless network and only one or just a small number of EAPs need to be managed, Standalone Mode is recommended. In Standalone Mode, each EAP can be configured singly by the Omada app or the web browser on its own management web page.

Omada app is a mobile application designed for conveniently managing Omada series EAP products. For detailed instructions about how to use Omada app to manage your network, please refer to the appendix of this User Guide:Appendix: Omada App.

This User Guide introduces how to configure the Standalone EAP on its web page.

Note

The web page of an EAP is inaccessible while it is managed by Omada Controller. To turn the EAP back to Standalone Mode and access its web page, you can Forget the EAP on Omada Controller to reset the EAP or simply close Omada Controller.

5

1.2 Build the Network Topology

To manage the EAPs in Standalone mode, refer to the following topology.

 

 

 

 

 

Switch

Router (DHCP Server)

 

 

 

 

 

 

LAN: 192.168.0.1

PC

EAP

EAP

IP: 192.168.0.100

 

 

Clients

The router is the gateway of the network, and devices in the LAN surf the internet via the router. At the same time, the router acts as a DHCP server to assign dynamic IP addresses to the EAPs and clients.

The Layer 2 switch is connected to the LAN interface of the router.

The PC and the EAPs are all connected to the Layer 2 switch. Since the PC and the EAPs are in the same network segment, the PC can log in to the web pages of the EAPs and manage them.

6

1.3 Log In to the EAP

The following sections introduce how to log in to the EAP via a wireless connection and a wired connection.

1.3.1   Log In via a wireless connection

To access the management web page via a wireless connection, you can use either the domain name or the IP address of the EAP. We recommend you to log in using the domain name for a wireless connection. In this method, you needn’t know the IP address of the EAP, but you need to prepare a wireless client device, such as a wireless laptop. Follow the steps below to log in to the EAP via domain name:

1. Set the wireless client device to get IP settings assigned automatically.

2. Search the default SSID (Network name) using your wireless client device and connect to the wireless network of the EAP. The default SSID of the EAP is printed on the product label at the bottom of the device. The dual-band EAP has two default SSIDs named TP-Link_2.4GHz_XXXXXX and TP-Link_5GHz_XXXXXX on the 2.4GHz band and 5GHz band, and the single-band EAP has a default SSID named TP-Link_2.4GHz_ XXXXXX on the 2.4GHz band.

7

3. Make sure that the wireless client has been assigned the IP address and has got the IP address of the DNS server and the gateway.

4. Launch a web browser on the client device and enter http://tplinkeap.net in the address bar to load the login page of the EAP. Use admin for both of the username and password to log in.

Tips

To facilitate access to the EAP via a wired device, you can set a static IP address for the EAP and remember it well or write it down. But make sure that this IP address is not being used in the same

LAN. For detailed instructions about how to set a static IP address for the EAP, refer toManage the IP Address of the EAP.

8

1.3.2  Log In via a wired connection

For a wired connection, you can only log in to the EAP via its IP address. In this method, you need to know the IP address of the EAP first. Follow the steps below to log in via the IP address of the EAP with a wired client. The method of log in via the IP address wirelessly is similar.

1. Get the IP address of the EAP. There are two methods.

Log in to the router which acts as the DHCP server. In the DHCP client list, find the IP address of your EAP according to its MAC address. The MAC address can be found at the bottom of the EAP.

Go to http://www.tp-link.com/en/download/EAP-Controller.html#EAP_Discovery_ Tool to download EAP Discovery Utility. EAP Discovery Utility is a software that can scan all EAPs in the same network segment. Install and launch EAP Discovery Utility on the PC, and find the IP address of the EAP. In the following figure, the IP address of the EAP is 192.168.0.5.

9

2. Launch a web browser and enter 192.168.0.5 in the address bar to load the login page of the EAP. Use admin for both of the username and password to log in.

Tips

••To facilitate access to the EAP via a wired device, you can set a static IP address for the EAP and remember it well or write it down. But make sure that this IP address is not being used in the same LAN. For detailed instructions about how to set a static IP address for the EAP, refer to Manage the IP Address of the EAP.

••The DHCP fallback IP address is 192.168.0.254 by default, which you can use to log in to its web management page when the DHCP server is not available in your network. Follow the steps below:

1.Connect the EAP to your computer with an Ethernet Cable.

2.Assign a static IP address 192.168.0.X (X ranges between 2 and 253) together with the subnet mask 255.255.255.0 to your computer.

3.Open a web browser and enter 192.168.0.254 in the address bar to load the login page of the EAP.

10

1.4 Do the Basic Configurations

After Logging in to EAP, follow the step-by-step instructions to complete the basic configurations.

1. In the pop-up window, configure a new username and a new password for your user account, then click Next.

2. For the dual-band EAP, select at least one radio band between 2.4GHz and 5GHz to configure the SSID and password. For the single-band EAP, configure the SSID and password on the 2.4GHz band. Click Save.

11

3. The following page will appear. Make sure that your device has connected to the new wireless network and tick the checkbox. Then click Finish.

Tips

If needed, you can also create more new SSIDs. For detailed instructions about how to create new SSIDs, refer toConfigure SSIDs.

••Configure the Wireless Parameters

••Configure Portal Authentication

••Configure VLAN

••Configure MAC Filtering

••Configure Scheduler

••Configure Band Steering

••Configure QoS

••Configure Rogue AP Detection

14

2.1 Configure the Wireless Parameters

To configure the wireless parameters, go to the Wireless > Wireless Settings page.

For a dual-band EAP, there are two bands: 2.4GHz and 5GHz. The wireless parameters are separately set on each band. You can click to select a band and configure the wireless parameters on this band.

15

TP-Link Omada EAP110 Manual

Before configuring the wireless parameters on each band, check the box to enable 2.4GHz or 5GHz Wireless Radio. Only when this option is enabled will the wireless radio on 2.4GHz or 5GHz band works.

Demonstrated with 2.4GHz, the following sections introduce these contents: Configure SSIDs and Configure Wireless Advanced Settings.

2.1.1  Configure SSIDs

SSID (Service Set Identifier) is used as an identifier for a wireless LAN, and is commonly called as the “network name“. Clients can find and access the wireless network through the SSID. For one EAP, you can build up to eight SSIDs per frequency band.

16

Follow the steps below to create an SSID on the EAP:

 

1. If your EAP is a dual-band device, click

to choose a frequency band on

which the new SSID will be created.

 

2. Click

to add a new SSID on the chosen band.

 

Tips

 

 

You can also click to edit the specific SSID which already exists in the list. And you can click to delete the SSID in the list.

3. Configure the following required parameters for this SSID:

SSID

Specify a name for the wireless network.

SSID Broadcast

With the option enabled, EAP will broadcast the SSID to the nearby

 

hosts, so that those hosts can find the wireless network identified by

 

this SSID. If this option is disabled, users must enter the SSID manually

 

to connect to the EAP.

Security Mode

Select the security mode of the wireless network. There are four

 

options:

 

None: Clients can access the wireless network without authentication.

 

WEP/WPA-Enterprise/WPA-PSK: Clients need to pass the

 

authentication before accessing the wireless network. For network

 

security, we recommend that you encrypt your wireless network. The

 

following sections will introduce how to configure these security modes.

Guest Network

With this option enabled, guest network will block clients from reaching

 

any private IP subnet.

Rate Limit

With this option enabled, the download and upload rate of each client

 

which connects to the SSID will be limited to balance bandwidth usage.

 

You can limit the download and upload rate for some specific clients by

 

configuring rate limit in client list, refer to View Client Information to

 

get more details.

 

Note that the download and upload rate will be limited to the smaller

 

value if you set the limit value both in SSID and client configuration.

4. Click OK to create the SSID.

Following is the detailed instructions about how to configure WEP, WPA-Enterprise and

WPA-PSK.

••WEP

WEP (Wired Equivalent Privacy) is a traditional encryption method. It has been proved that WEP has security flaws and can easily be cracked, so WEP cannot provide effective

17

protection for wireless networks. Since WPA-PSK and WPA-Enterprise are much safer than WEP, we recommend that you choose WPA-PSK or WPA-Enterprise if your clients also support them.

Note

WEP is not supported in 802.11n mode or 802.11ac mode. If WEP is applied in 802.11n, 802.11 ac or 802.11n/ac mixed mode, the clients may not be able to access the wireless network. If WEP is applied in 802.11b/g/n mode (2.4GHz) or 802.11a/n (5GHz), the EAP may work at a low transmission rate.

The following table detailedly introduces how to configure each item:

 

Type

Select the authentication type for WEP.

 

 

 

Auto: The EAP can select Open System or Shared Key automatically based

 

 

 

on the wireless capability and request of the clients.

 

 

 

Open System: Clients can pass the authentication and associate with

 

 

 

the wireless network without password. However, correct password is

 

 

 

necessary for data transmission.

 

 

 

Shared Key: Clients have to input the correct password to pass the

 

 

 

authentication, otherwise the clients cannot associate with the wireless

 

 

 

network or transmit data.

 

 

Key Selected

Select one key to specify. You can configure four keys at most.

 

 

 

 

 

 

WEP Key Format

Select ASCII or Hexadecimal as the WEP key format.

 

 

 

ASCII: With this format selected, the WEP key can be any combination of

 

 

 

keyboard characters of the specified length.

 

 

 

Hexadecimal: With this format selected, the WEP key can be any

 

 

 

combination of hexadecimal digits (0-9, a-f, A-F) with the specified length.

 

 

Key Type

Select the WEP key length for encryption.

 

 

 

64Bit: Enter 10 hexadecimal digits or 5 ASCII characters.

 

 

 

128Bit: Enter 26 hexadecimal digits or 13 ASCII characters.

 

 

 

152Bit: Enter 32 hexadecimal digits or 16 ASCII characters.

 

18

Key Value

Enter the WEP keys. The length and valid characters are determined by the

 

key format and key type.

••WPA-Enterprise

WPA-Enterprise (Wi-Fi Protected Access-Enterprise) is a safer encryption method compared with WEP and WAP-PSK. It requires a RADIUS server to authenticate the clients via 802.1X and EAP (Extensible Authentication Protocol). WPA-Enterprise can generate different passwords for different clients, which ensures higher network security. But it also costs more to maintain the network, so it is more suitable for business networks.

The following table introduces how to configure each item:

Version

Select the version of WPA-Enterprise.

 

Auto: The EAP will automatically choose the version used by each

 

client device.

 

WPA/WPA2: They’re two versions of WPA security mode. WPA2 is an

 

update of WPA. Compared with WPA, WPA2 introduces AES algorithm

 

and CCMP encryption. Theoretically, WPA2 is securer than WPA.

19

 

Encryption

Select the Encryption type.

 

 

 

Auto: The default setting is Auto and the EAP will select TKIP or AES

 

 

 

automatically based on the client device’s request.

 

 

 

TKIP: Temporal Key Integrity Protocol. TKIP is not supported in

 

 

 

802.11n mode, 802.11ac mode or 802.11n/ac mixed mode. If TKIP is

 

 

 

applied in 802.11n, 802.11 ac or 802.11n/ac mixed mode, the clients

 

 

 

may not be able to access the wireless network. If TKIP is applied in

 

 

 

11b/g/n mode (2.4GHz) or 11a/n mode(5GHz), the device may work at

 

 

 

a low transmission rate.

 

 

 

AES: Advanced Encryption Standard. It is securer than TKIP.

 

 

 

 

 

 

RADIUS Server IP

Enter the IP address of the RADIUS Server.

 

 

 

 

 

 

RADIUS Port

Enter the port number of the RADIUS Server.

 

 

 

 

 

 

RADIUS Password

Enter the shared secret key of the RADIUS server.

 

 

 

 

 

 

RADIUS Accounting

Enable or disable RADIUS accounting feature.

 

 

 

 

 

 

Accounting Server IP

Enter the IP address of the accounting server.

accounting information updates. By default, the function is disabled.

 

 

 

Enter the appropriate duration between updates for EAPs in Interim

 

 

 

Update Interval.

 

 

Interim Update

With Interim Update enabled, specify the appropriate duration

 

 

Interval

between updates for EAPs. The default duration is 600 seconds.

 

 

Group Key Update

Specify an update period of the encryption key. The update period

 

 

Period

instructs how often the EAP should change the encryption key. 0

 

 

 

means that the encryption key does not change at anytime.

 

20

••WPA-PSK

WPA-PSK (Wi-Fi Protected Access-PSK) is based on a pre-shared key. It is characterized by high safety and simple settings, so it is mostly used by common households and small businesses.

The following table introduces how to configure each item:

 

Version

Select the version of WPA-Enterprise.

 

 

 

Auto: The EAP will automatically choose the version used by each client

 

 

 

device.

 

 

 

WPA-PSK/WPA2-PSK: They’re two versions of WPA-PSK security mode.

 

 

 

WPA2-PSK is an update of WPA-PSK. Compared with WPA, Theoretically,

 

 

 

WPA2 is securer than WPA.

 

 

Encryption

Select the Encryption type.

 

 

 

Auto: The default setting is Auto and the EAP will select TKIP or AES

 

 

 

automatically based on the client device’s request.

 

 

 

TKIP: Temporal Key Integrity Protocol. TKIP is not supported in 802.11n

 

 

 

mode, 802.11ac mode or 802.11n/ac mixed mode. If TKIP is applied in

 

 

 

802.11n, 802.11 ac or 802.11n/ac mixed mode, the clients may not be able

 

 

 

to access the wireless network. If TKIP is applied in 11b/g/n mode (2.4GHz)

 

 

 

or 11a/n mode(5GHz), the device may work at a low transmission rate.

 

 

 

AES: Advanced Encryption Standard. It is securer than TKIP.

 

 

Wireless

Configure the wireless password with ASCII or Hexadecimal characters.

 

 

Password

••For ASCII, the length should be between 8 and 63 and the valid characters

 

 

 

 

 

 

contain numbers, letters (case-sensitive) and common punctuations.

 

 

 

••For Hexadecimal, the length should be between 8 and 64, and the valid

 

 

 

characters contain: 0-9, a-f, A-F.

 

 

Group Key

Specify an update period of the encryption key. The update period instructs

 

 

Update Period

how often the EAP should change the encryption key. 0 means that the

 

 

 

encryption key does not change at anytime.

2.1.2  Configure Wireless Advanced Settings

Proper wireless parameters can improve the performance of your wireless network. This section introduces how to configure the advanced wireless parameters of the EAP, includingRadio Setting,Load Balance,Airtime Fairness and More Settings.

Radio Setting

Radio settings directly control the behavior of the radio in the EAP and its interaction with the physical medium; that is, how and what type of signal the EAP emits.

Select the frequency band (2.4GHz/5GHz) and configure the following parameters.

Wireless Mode

Select the IEEE 802.11 mode the radio uses.

 

When the frequency of 2.4GHz is selected, 802.11b/g/n mixed, 802.11b/g

 

mixed, and 802.11n only modes are available:

 

802.11b/g/n mixed: All of 802.11b, 802.11g, and 802.11n clients operating

 

in the 2.4GHz frequency can connect to the EAP. We recommend you

 

select the 802.11b/g/n mixed mode.

 

802.11b/g mixed: Both 802.11b and 802.11g clients can connect to the

 

EAP.

 

802.11n only: Only 802.11n clients can connect to the EAP.

 

When the frequency of 5GHz is selected, 802.11 a/n/ac mixed, 802.11n/ac

 

mixed and 802.11 ac only are available:

 

802.11a/n/ac mixed: All of 802.11a, 802.11n clients and 802.11ac clients

 

operating in the 5GHz frequency can connect to the EAP.

 

802.11n/ac mixed: Both 802.11n clients and 802.11ac clients operating in

 

the 5GHz frequency can connect to the EAP.

 

802.11ac only: Only 802.11ac clients can connect to the EAP.

Channel Width

Select the channel width of the EAP. The available options differ among

 

 

 

different EAPs.

 

 

 

For some EAPs, available options include 20MHz, 40MHz and 20/40MHz.

 

 

 

For other EAPs, available options include 20MHz, 40MHz, 80MHz and

 

 

 

20/40/80MHz.

 

 

 

When the radio mode includes 802.11n, we recommend you set the channel

 

 

 

bandwidth to 20/40 MHz or 20/40/80MHz to improve the transmission

 

 

 

speed. However, you may choose a lower bandwidth due to the following

 

 

 

reasons:

 

 

 

••To increase the available number of channels within the limited total

 

 

 

bandwidth.

 

 

 

••To avoid interference from overlapping channels occupied by other

 

 

 

devices in the environment.

 

 

 

••Lower bandwidth can concentrate higher transmit power, increasing

 

 

 

stability of wireless links over long distances.

 

 

Channel Limit

Check the box to enable the Channel Limit function. With this function

 

 

 

enabled, the wireless frequency 5150MHz~5350MHz will be disabled. This

 

 

 

function can influence the available options in Channel.

 

 

 

This feature is only available for 5GHz wireless configuration of EAP225-

 

 

 

Outdoor.

 

 

Channel

Select the channel used by the EAP. For example, 1/2412MHz means that

 

 

 

the channel is 1 and the frequency is 2412MHz.

 

 

 

By default, the channel is automatically selected, and we recommend that

 

 

 

you keep the default setting.

 

23

Tx Power (EIRP)

Specify the transmit power value.

 

If this value is set to be larger than the maximum transmit power that is

 

allowed by the local regulation, the regulated maximum transmit power will

 

be applied in the actual situation.

 

Note: In most cases, it is unnecessary to use the maximum transmit power.

 

Specifying a larger transmit power than needed may cause interference to

 

the neighborhood. Also it consumes more power and reduces longevity of

 

the device.

Load Balance

With the Load Balance feature, you can limit the maximum number of clients who can access the EAP. In this way, you can achieve rational use of network resources.

Follow the steps below to configure Load Balance:

1. Click

to choose a frequency band on which the load balance feature will

take effect.

 

2. Check the box to enable Load Balance.

3. Specify the maximum number of clients who can connect to the EAP at the same time. While the number of connected clients has reached the limit and there are more clients requesting to access the network, the EAP will disconnect those with weaker signals.

4. Click Save.

Airtime Fairness

Note

EAP225_V3, EAP225-Outdoor_V1, EAP245_V3 support this feature.

With Airtime Fairness enabled, each client connected to the EAP can get the same amount of time to transmit data, avoiding low-data-rate clients to occupy too much network bandwidth.

24

Compared with the relatively new client devices, some legacy client devices support slower wireless rate. If they communicate with the same EAP, the slower clients take more time to transmit and receive data compared with the faster clients. As a result, the overall wireless throughput of the network decreases.

Therefore we recommend you check the box to enable this function under multirate wireless networks. In this way, the faster clients can get more time for the data transmission and the network overall throughput can be improved.

Note that 50 wireless clients at most can connect to the EAP in 2.4GHz band when this function enabled on EAP245_V3, EAP225_V3 and EAP225-Outdoor_V1.

More Settings

Proper wireless parameters can improve the network’s stability, reliability and communication efficiency. The advanced wireless parameters consist of Fast Roaming, Beacon Interval, DTIM Period, RTS Threshold, and Fragmentation Threshold.

The following table introduces how to configure each item:

Beacon Interval

Beacons are transmitted periodically by the EAP to announce the presence

 

of a wireless network for the clients. Beacon Interval determines the time

 

interval of the beacons sent by the EAP.

 

You can specify a value between 40 and 100ms. The default is 100ms.

 

 

25

 

DTIM Period

The DTIM (Delivery Traffic Indication Message) is contained in some

 

 

 

Beacon frames. It indicates whether the EAP has buffered data for client

 

 

 

devices. The DTIM Period indicates how often the clients served by this

 

 

 

EAP should check for buffered data still on the EAP awaiting pickup.

 

 

 

You can specify the value between 1-255 Beacon Intervals. The default

 

 

 

value is 1, indicating that clients check for buffered data at every beacon.

 

 

 

An excessive DTIM interval may reduce the performance of multicast

 

 

 

applications, so we recommend you keep the default value.

 

 

RTS Threshold

RTS/CTS (Request to Send/Clear to Send) is used to improve the data

 

 

 

transmission efficiency of the network with hidden nodes, especially when

 

 

 

there are lots of large packets to be transmitted.

 

 

 

When the size of a data packet is larger than the RTS Threshold, the RTS/

 

 

 

CTS mechanism will be activated. With this mechanism activated, before

 

 

 

sending a data packet, the client will send an RTS packet to the EAP to

 

 

 

request data transmitting. And then the EAP will send CTS packet to inform

 

 

 

other clients to delay their data transmitting. In this way, packet collisions

 

 

 

can be avoided.

 

 

 

For a busy network with hidden nodes, a low threshold value will help

 

 

 

reduce interference and packet collisions. But for a not-so-busy network, a

 

 

 

too low threshold value will cause bandwidth wasting and reduce the data

 

 

 

throughput. The recommended and default value is 2347 bytes.

 

 

Fragmentation

The fragmentation function can limit the size of packets transmitted over

 

 

Threshold

the network. If the size of a packet exceeds the Fragmentation Threshold,

 

 

 

the fragmentation function is activated and the packet will be fragmented

 

 

 

into several packets.

 

 

 

Fragmentation helps improve network performance if properly configured.

 

 

 

However, a too low fragmentation threshold may result in poor wireless

 

 

 

performance caused by the extra work of dividing up and reassembling

 

 

 

of frames and increased message traffic. The recommended and default

 

 

 

value is 2346 bytes.

 

2.2 Configure Portal Authentication

Portal authentication provides authentication service to the clients that only need temporary access to the wireless network, such as the customers in a restaurant or in a supermarket. To access the network, these clients need to enter the authentication login page and use the correct login information to pass the authentication. In addition, you can customize the authentication login page and specify a URL which the authenticated clients will be redirected to.

In this module, you can also configure Free Authentication Policy, which allows the specific clients to access the specific network resources without authentication.
