Dear Wey, My situation is very similar to Norbert's. At my house, I have no issues at all, but at my university, I tend to have issues. In the past, using 11n_disable=1 would cause the wireless interface to break until I executed "modprobe -r iwlagn && modprobe iwlagn" as root. That was around Linux 3.0-rc4. I haven't tried it since, but what seems to help is "iwconfig wlan0 rts 0", but even that is not perfect. I just gave "modprobe -r iwlagn && modprobe iwlagn 11n_disable=1" another try and it makes no difference. Issues with the campus Wi-Fi are not isolated to Linux users. I suspect it has something to do with the 100 or so access points that I see when I do "iwlist wlan0 scan" at my university and the 4 that I see when I do that off campus. I don't want to imagine how many devices are trying to use the available bandwidth. I imagine that implementing "auto" for rts would improve both my and Norbert's situations.
