Nuclias Connect

Introduction

Nuclias Connect is D-Link’s centralized management solution for Small-to-Medium-Sized Business (SMB) networks. Nuclias Connect makes it easier to analyze, automate, congure, optimize, scale, and secure your network — delivering the convenience of an Enterprise-wide management solution, at an SMB price. Nuclias Connect gives you the nancial and technical exibility to expand from a small network to a larger one of up to 1,000 Access Points APs, while retaining a robust and centralized management system. With its intuitive Graphical User Interface (GUI), a wealth of enhanced AP features, and a setup wizard that supports 11 languages, Nuclias Connect minimizes the hassle of deployment, conguration, and administration tasks.
Deployable on a Windows server (or Linux via Docker), PC, or Smartphone (via lite management app) the Nuclias Connect free-to-download software is capable of managing up to 1,000 APs without licensing charges, coupled with an inexpensive optional hardware controller (DNH-100 Nuclias Connect Hub) suitable for remote locations. Through software-based monitoring and remote management of all wireless Access Points (APs) on your network, Nuclias Connect oers tremendous exibility compared to traditional hardware-based unied management systems. Conguration can be done remotely. Network trac analytics are available at a glance (in whole or in part). Load Balancing, Airtime Fairness, and Localized Throttling are enabled.
Nuclias Connect supports multi-tenancy, so network administrators can grant localized management authority for local networks. In addition, because APs can support 8 SSIDs per radio (16 SSIDs per dual band APs), administrators have the option of using one SSID to create a guest network for visitors.
Nuclias Connect provides direct AP discovery and provisioning when it shares the same Layer-2/Layer-3 network with a given AP, allowing users to nd APs and import proles with minimum eort, which can be applied as needed to groups or individual APs for even more eective conguration.
Since Nuclias Connect’s software operates transparently on the network, an AP can be deployed anywhere in an NAT environment. Admins can provide and manage a variety of distributed deployments, including setting and admin account conguration for each deployment.
Nuclias Connect allows for multiple user authentications while enabling specic access control congurations for each SSID, giving admins the option of conguring separate internal networks for dierent subnets, while enabling more advanced Value-Added Services, such as Captive Portal or Wi-Fi Hotspot.

Wireless Security

Wireless security is a key concern for any wireless network installed. Unlike any other networking method wireless networks will broadcast it’s presence for anyone to connect to it. Today, wireless security has advanced to a level where it is virtually impenetrable.
There are mainly two forms of wireless encryption and they are called Wired Equivalent Privacy (WEP) and Wi-Fi Protected Access (WPA). WEP was the rst security method developed. It is a low level encryption but better than now encryption. WPA is the newest encryption standard and with the advanced WPA2 standard wireless networks have nally reach a point where the security is strong enough to give users the peace of mind when installing wireless networks.
Wired Equivalent Privacy (WEP)
WEP provides two variations called Open System and Shared Key.
y Open System will send a request to the access point and if the key used matches the one congured on the access point, the access point will
return a success message back to the wireless client. If the key does not match the one congured on the access point, the access point will deny the connection request from the wireless client.
y Shared Key will send a request to the access point and if the key used matches the one congured on the access point, the access point will
send a challenge to the client. The client will then again send a conrmation of the same key back to the access point where the access point will either return a successful or a denial packet back to the wireless client.

encryption.

Wi-Fi Protected Access (WPA / WPA2)
The WPA protocol is based on the 802.11i standard. WPA oers two variations called WPA-Personal (PSK) and WPA-Enterprise (EAP). WPA-EAP requires the user to install a Radius Server on the network for authentication, while WPA-Personal does not. In comparison, WPA-PSK is seen as a weaker authentication variation than WPA-EAP. WPA-EAP is the highest level of wireless security a user can use for wireless today.
WPA2 is an upgrade of WPA and solves security issues found in WPA. WPA2 also oers two variations called WPA2-Personal (PSK) and WPA2­Enterprise (EAP) similar to WPA.

Beacon Interval (40-500) Beacons are packets sent by an access point
to synchronize a wireless network. Specify a value in milliseconds. The default (100) is recommended. Setting a higher beacon interval can help to save the power of wireless clients, while setting a lower one can help a wireless client connect to an access point faster.
