You have been subscribed to a public bug:

Recently upgraded from 11.04 to 11.10 but now whenever I connect to my
home network via wifi the router actually locks up (drops all network
connections, refuses new ones, etc). The only work around I've found is
to power cycle the router and use a wired connection.

Router: Cisco Linksys WRT120N with latest firmware version 1.0.06
