Chapter 6. TroubleShooting

This chapter provides solutions to problems that may occur during the installation
and operation of ZEW2540P. Read the descriptions below to solve your problems.

Q1. The ZEW2540P does not work properly.

Reinsert ZEW2540P into your PC’s USB slot.
Right click on My Computer and select Properties. Select the device manager and
click on the Network Adapter. You will find ZEW2540P if it is installed successfully.
If you see the yellow exclamation mark, the resources are conflicting. You will see
the status of ZEW2540P. If there is a yellow question mark, please check the
following:
Make sure that your PC has a free IRQ (Interrupt ReQuest, a hardware interrupt
on a PC.)
Make sure that you have inserted the right adapter and installed the proper driver.
If ZEW2540P does not function after attempting the above steps, remove it and
do the following:
Uninstall the driver software from your PC.
Restart your PC and repeat the hardware and software installation as specified in
this User Guide.

Q2. I cannot communicate with the other computers linked via Ethernet
in the Infrastructure configuration.

Make sure that the PC to which ZEW2540P is associated is powered on.
Make sure that ZEW2540P is configured on the same channel and with the same
security options as with the other computers in the Infrastructure configuration.

Q3. What should I do when the computer with ZEW2540P installed is
unable to connect to the wireless network and/or the Internet?

Check that the LED indicators for the broadband modem are indicating normal
activity. If not, there may be a problem with the broadband connection.
Check that the LED indicators on the wireless router are functioning properly. If
not, check that the power adapter and Ethernet cables are firmly connected.
Check that the IP address, subnet mask, gateway, and DNS settings are correctly
entered for the network.
In Infrastructure mode, make sure the same Service Set Identifier (SSID) is
specified on the settings for the wireless clients and access points.
In Ad-Hoc mode, both wireless clients will need to have the same SSID. Please
note that it might be necessary to set up one client to establish a BSS (Basic
Service Set) and wait briefly before setting up other clients. This prevents several
clients from trying to establish a BSS at the same time, which can result in
multiple singular BSSs being established, rather than a single BSS with multiple
clients associated to it.
Check that the Network Connection for the wireless client is configured properly.
If Security is enabled, make sure that the correct encryption keys are entered on
both ZEW2540P and the access point.

Q4. I can’t find any wireless access point / wireless device in Network
tab.

 Click Rescan for few more times and see if you can find any wireless access

point or wireless device.

 Please move closer to any known wireless access point.
 Ad-hoc function must be enabled for the wireless device you wish to establish

a direct wireless link.

 Please adjust the position of ZEW2540P (you may have to move your

computer if you’re using a notebook computer) and click Rescan button for
few more times. If you can find the wireless access point or wireless device
you want to connect by doing this, try to move closer to the place where the
wireless access point or wireless device is located.

Q5. Nothing happens when I click Launch config utilities

 Please make sure ZEW2540P is inserted into your computer’s USB port. If the

Ralink configuration utility’s icon is black, ZEW2540P is not detected by your
computer.

 Reboot the computer and try again.
 Remove ZEW2540P and insert it into another USB port.
 Remove the driver and re-install.

Q6. I can not establish connection with a certain wireless access point

 Click Connect for few more times.
 If the SSID of access point you wish to connect is hidden (nothing displayed

in SSID field in Network tab), you have to input correct SSID of the access
point you wish to connect.

 You have to input correct passphrase / security key to connect an access

point with encryption.

 The access point you wish to connect only allows network cards with specific

MAC address to establish connection. Please go to About tab and write the
value of Phy_Addess down, then present this value to the owner of access
point to add the MAC address of your ZEW2540P to owner’s access point’s
list.

Q7. The network is slow / having problem when transferring large files

 Move closer to the place where access point is located.
 Enable Wireless Protection in Advanced tab.
 Try a lower TX Rate in Advanced tab.
 Disable Tx Burst in Advanced tab.
 Enable WMM in WMM tab if you need to use multimedia / telephony related

applications.

 Disable WMM – Power Save Enable in WMM tab.
 There could be too much people using the same radio channel. Ask the owner

of the access point to change the channel number.
