Comment 92 for bug 548992

I've also had this happen quite often, but only when I am in a busy wireless environment like my school or a cafe. Similar to Alberto my school has multiple AP's. Connecting really depends on how many people around seem to be using the wireless. When there is almost no one around me I can usually connect to the wireless network with only intermittent drops. Note that this does not happen in Windows 7. Sadly this problem cripples any sort of productivity in Ubuntu.

I have Ubuntu 10.10 installed with linux-backports-modules-wireless-maverick-generick. My wifi card is Intel 5100. As above I have tried disabling ipv6. Adding options iwlagn 11n_disable=1 11n_disable50=1, which didn't help. Whenever I can get around to loading Ubuntu again on a wired network I may attempt the Wicd instead of network manager. Unfortunately nowadays finding a wired network has become quite difficult.
