Public bug reported: NetGear WN111v2 USB wireless adapter connecting to WEP encrypted 802.11g network using Network Manager on 11.04 connects on startup then disconnects after about one minute. Behavior after that depends on whether the carl9170 and/or ar9170usb modules are loaded. The WN111v2 works perfectly using Network Manager and 10.10 on a similar Atom CPU machine. Stopping network manager and attempting to connect manually using iwconfig and ifconfig was unsuccessful, so I suspect this may be a driver/kernel issue rather than Network Manager.
carl9170 loaded (ar9170usb blacklisted) Connects on startup. Loses connection, shows authentication dialog, reconnects. Loses connection, shows authentication dialog... ar9170usb loaded (carl9170 blacklisted) Connects on startup. Loses connection, shows authentication dialog, fails to reconnect. Shows authentication dialog... Both loaded (neither blacklisted) Connects on startup. Loses connection, shows authentication dialog, fails to reconnect. Shows authentication dialog... Attached is a tar.gz file containing /var/log/syslog output from bootup to the second authentication dialog in each case. It seems odd to me that wpa_supplicant is involved when WEP encryption is used, but that is probably because I don't understand the operation of Network Manager. Network Manager and 11.04 are working on an eeePC 1000 with Realtek RT2860 miniPCIe wireless using the rt2800pci module (rt2860sta blacklisted) so I have ordered a Realtek chipset USB wireless stick to try on the problem machine. ** Affects: ubuntu Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/779142 Title: ar9170 usb wireless disconnects repeatedly -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
