Comment 125 for bug 352228

I'm experiencing the same problem.

I have a Dell Precision M4400 from about 1 year, lspci displays this info about my wifi card:

0c:00.0 Network controller: Intel Corporation Wireless WiFi Link 5100

I never experienced this type of errors till yesterday when I've changed the wifi router.
Now I have a LINKSYS WRT160N-EZ. Before this one I've used a DLINK DSL 624 GT and a Sitecom WL 127.
The difference betwen the Linksys and the other ones is that the linksys support the N protocol. I have disabled it in the wireless config and as wrote here http://ubuntuforums.org/showthread.php?t=1239871:

options iwlagn 11n_disable=1 11n_disable50=1
in /etc/modprobe.d/options.conf

Now I'm waiting for see if it is a valid solution.
