Loss of IP connectivity on a building-to-building WLAN

Hi all,

I have two 350 bridges (both 12.01T1). One is configured as root and the other as non-root bridge. I have WEP (full encryption, 128Bit), TKIP, MIC and Key rotation=600s configured. The bridges do associate (Status=OK), and I can connect the devices on the remote LAN. After a couple of hours the connectivity (IP) to the devices is broken, but I see the remote (non-root) bridge in a associated state (status still OK). The only difference is that in the association table of the root bridge there's no more IP address behind the name of the remote bridge, whose config is still there. If I turn off WEP the IP connection is restored.

Can anyone help me with that? Thanx!

May be you must have missed something in the config, use the following doc and do a check of the config,

Hi ,

Are you doing LEAP or WEP ?

If you are doing WEP ONLY you can not tun on Key Rotation .

key rotatio is only for LEAP and for now wep .

So after 600 sec you will see bridge going down .

Make wep key roation to 0
