Check the settings for QoS. If it is disabled, you might consider activating it. If

it is enabled, you might consider raising or lowering the priority for some

21.5 Wireless AP Troubleshooting

I cannot access the NWA3000-N series AP or ping any computer from the WLAN.

1 Make sure the wireless LAN is enabled on the NWA3000-N series AP

2 Make sure the wireless adapter on the wireless station is working properly.

3 Make sure the wireless adapter (installed on your computer) is IEEE 802.11

compatible and supports the same wireless standard as the NWA3000-N series AP.

4 Make sure your computer (with a wireless adapter installed) is within the

transmission range of the NWA3000-N series AP.

5 Check that both the NWA3000-N series AP and your wireless station are using the

same wireless and wireless security settings.

6 Make sure traffic between the WLAN and the LAN is not blocked by the firewall on

the NWA3000-N series AP.

7 Make sure you allow the NWA3000-N series AP to be remotely accessed through

the WLAN interface. Check your remote management settings.

Hackers have accessed my WEP-encrypted wireless LAN.

WEP is extremely insecure. Its encryption can be broken by an attacker, using

widely-available software. It is strongly recommended that you use a more

effective security mechanism. Use the strongest security mechanism that all the

wireless devices in your network support. WPA2 or WPA2-PSK is recommended.

The wireless security is not following the re-authentication timer setting I

specified.
