** 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) 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/v3.5.3-quantal/ http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.5.4-quantal/ http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6-rc1-quantal/ http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6-rc5-quantal/ http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6-rc6-quantal/ http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6-rc7-quantal/ http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6-quantal/ http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6.1-quantal/ http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6.3-quantal/ http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6.8-raring/ http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.7-raring/ + http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.7.6-raring/ 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. Wireless Access Point Manufacturer, Model: FRITZ!Box Fon WLAN 7141 Firmware-Version: 40.04.76 Encryption Type: WPA2 (CCMP) No MAC filtering. Other WiFi devices (Android Phones, Netbooks, Laptop) works with this wireless access point without problems.
