This somehow seems to be related to periodic scanning for other APs in range (e.g., NetworkManager does this). When configured manually using wpa_supplicant, I found the connection to be stable, unless I ran iwlist scan commands periodically - doing so reproducibly kills the connection after a random amount of time (I've seen this happen after five minutes as well as over an hour), rendering the device unusable afterwards until it is replugged.
There is a patched version of NetworkManager that does not perform regular scans while a connection is established (see https://launchpad.net/~volanin/+archive/ppa), which provides a stable workaround for the problem; since I've been using that version, the wireless connection has been absolutely stable here. Also, NM 0.8.1 will regularly feature non-scanning behaviour for connections locked to a specific BSSID. -- ar9170usb wifi module crash + instabile connection https://bugs.launchpad.net/bugs/540827 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
