Title: Kernel 3.0 wireless Warning bug Status in Linux Mint: New Bug description: I'm using Ubuntu 11.10 64-bits. My hardware is an Acer Aspire 5630 notebook. Wi-fi card has 802.11 B/G support (no N), and is connected to a router running a G+N network. All other devices can connect to it with no problem, and the same notebook also have no problems in windows with the network. The following problem keeps occurring repeatedly: The notebook can connect to the wireless network in G mode and browse the web without any problems, but at certain point (can be after 5 minutes of use, or also 2 hours of use, really random) it disconnects and can't connect to it anymore. The window to enter network password pops-up and then I enter the password and still it can't connect (same window pops-up again). It keeps going like this also for a random time (5min.~2hours) until it suddenly can connect again. Restarting seems to solve the not able to connect problem but doesn't keep it from occurring again. Dmesg shows the following trace: ~~~~~~~~~~~~~~~~ [ 233.380172] ieee80211 phy0: wlan0: No probe response from AP 00:1e:ab:05:7a:72 after 500ms, disconnecting.
