Gateway Problem
Possible Solution
Wireless client(s)
cannot send or receive
data
•
Perform the first four checks in “Cannot send or receive data.”
•
Check the Security Mode setting on the Wireless Primary
Network Page:
−
If you enabled WPA and configured a passphrase on the
SVG2501, be sure each affected wireless client has the
identical passphrase. If this does not solve the problem, check
whether the wireless client supports WPA.
−
If you enabled WEP and configured a key on the SVG2501, be
sure each affected wireless client has the identical WEP key. If
this does not solve the problem, check whether the client’s
wireless adapter supports the type of WEP key configured on
the SVG2501.
−
To temporarily eliminate the Security Mode as a potential
issue, disable security.
•
After resolving your problem, be sure to re-enable wireless
security.
•
On the Wireless Access Control Page, be sure the MAC address
for each affected wireless client is correctly listed.
Slow wireless

with WPA enabled
•
On the Wireless Primary Network Page, check whether the WPA
Encryption type is TKIP.
•
If all of your wireless clients support AES, change the WPA
Encryption to AES.
