** Description changed: The connection to the wireless network often gets lost and then reconnects. Furthermore the connection to the wireless network is often very slow (1 Mb/s). Sometimes after I have reloaded the ath9k kernel module, I can get a connection to the network and sometimes not. Sometimes I have to reboot the pc, because I can't get a connection, but often I can't get a connection after that. wireless card: TP-Link TL-WN951N (AR5416 / AR5008 / 168c:0023) - I tested the following mainline kernels.: + In these upstream kernel versions the bug is still present: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4-precise/ http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4.1-quantal/ http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4.6-quantal/ http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.5-quantal/ http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6-rc1-quantal/ - In those upstream kernel versions the bug is still present. - I had this problem also with Ubuntu Oneiric Ocelot 11.10 and with Ubuntu Natty Narwhal 11.04, but with Natty the problem was not so bad because - it was very rare. For this card exists an open source driver with the - help of Atheros itself, so far I know. Why the driver is so bad for - three Ubuntu versions? + it was very rare. - Similar problems or with the same ID / card: - https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1003406 - https://bugs.launchpad.net/ubuntu/+source/linux/+bug/995704 - https://bugs.launchpad.net/ubuntu/+source/linux/+bug/981538 - https://bugs.launchpad.net/ubuntu/+source/linux/+bug/981762 + Wireless Access Point Manufacturer, Model: FRITZ!Box Fon WLAN 7141 + Firmware-Version: 40.04.76 - BTW: I bought this card, because I had a similar problem with an other wireless card before.: - http://forum.ubuntuusers.de/topic/ralink-rt2561-rt61-belkin-f5d7000-v6000-rt61pci-wl/ + Encryption Type: WPA2 (CCMP) + No MAC filtering. + + Other WiFi devices (Android Phones, Netbooks, Laptop) works with this + wireless access point without problems.
