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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/548992 Title: Wireless connection frequently drops [deauthenticating by local choice (reason=3)] -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
