I have a ThinkPad T520 running Ubuntu 11.10 (AMD64). I am connecting to a Cisco WAP (802.11N) secured with WPA2. At random times (happens up to a few times per hour) I lose connectivity. The network shows as connected, but I cannot access any LAN or WAN resources (cannot ping my gateway either).

The only way to get it working again is to turn off the physical WLAN switch, wait a moment, and then turn it back on (disconnecting / reconnecting and disabling / reenabling via the software menu doesn't work).

Any ideas why this might be occurring and what I can do to fix this issue? Would like to test drive 11.10 for a bit longer, but will have to move back to Windows if I can't get this resolved (as it is impacting productivity).

Thank you in advance.

Can you provide us with syslog and dmesg logs around the time of the drops – benwh Feb 16 at 23:05
It would also be helpful if you could run the command 'lspci' and see if you can determine the chipset of the WLAN adapter. – Jayson Rowe Feb 20 at 3:18
