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 applications.
27.5 Wireless Connections
I cannot access the NWA1000 Series or ping any computer from the WLAN.
1
Make sure the wireless LAN (wireless radio) is enabled on the NWA1000 Series.
2
Make sure the radio or at least one of the NWA1000 Series’s radios is operating in AP mode.
3
Make sure the wireless adapter (installed on your computer) is working properly.
4
Make sure the wireless adapter (installed on your computer) is IEEE 802.11 compatible and supports the
same wireless standard as the NWA1000 Series’s active radio.
5
Make sure your computer (with a wireless adapter installed) is within the transmission range of the
NWA1000 Series.
6
Check that both the NWA1000 Series and your computer are using the same wireless and wireless
security 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.
If a RADIUS server authenticates wireless stations, the re-authentication timer on the RADIUS server has
priority. Change the RADIUS server’s configuration if you need to use a different re-authentication timer
setting.
I cannot get a certificate to import into the NWA1000 Series.

For
My Certificates
, you can import a certificate that matches a corresponding certification request that
was generated by the NWA1000 Series. You can also import a certificate in PKCS#12 format, including
the certificate’s public and private keys.
