Same issue, start happening week or two ago. Just drops connections, sometimes after 5 minutes, sometimes after few hours, and can't connect until full system restart. Few times a day, it's really annoying :(
Tried with 3 different AP, and 2 wificard (my laptop's internal and an usb wifi) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/793328 Title: network-manager drops wifi connection and fails to reconnect Status in “network-manager” package in Ubuntu: Incomplete Bug description: Binary package hint: network-manager Using Ubuntu 11.04 (Natty) with Unity, wifi connection is reliably lost after some time. Network-manager fails to re-establish the connection; nm-applet icon spins interminably. The applet menu shows the access point as "connected", but no connection through to internet is available. Disconnect/reconnect using menu fails. Network-manager requests WEP pass after long delay, but still does not connect. Only solution is to re-start Natty. Same hardware, same connection - no problem with maverick, no problem with oneiric.
