I've got a 4965 (Dell D830, 9.04) and a Linksys WRT610N. With it, I set up both 5GHz and 2.4GHz networks. My machine doesn't stay much longer connected. The 5 GHz network should save me from interference, but I keep jumping from one to another, to no avail. The simplest test is to transfer a large file, which will inevitably cause network hangs. Network manager sometimes recovers itself after a while, but at other times I have to progressively resort to reselecting either of the networks, disabling/enabling wireless, disabling/enabling networking and sometimes only a reboot will do it. I found that keeping a shell pinging the wireless router (or any other address) helps somewhat, stretching the up times. Mind you that I mostly use NFS inside my network, but not only.
This is a fresh install from yesterday, since the upgrade from 8.10 to 9.04 was presenting so many problems on key issues (wireless, suspend, kernel panics that I never had before since 2000 on various linuxen). An interesting info is that I had this wireless problem on 8.04, gone with 8.10 and now back on 9.04. I don't recall precisely the timing, but I guess it more or less matches upgrades/reinstalls of Ubuntu versions. -- [Jaunty] Intel wireless 3945ABG is unstable and disconnects frequently https://bugs.launchpad.net/bugs/348204 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
