Public bug reported:
After moving from 10.04 to 12.04, my wireless card stopped working reliably.
When generating internet traffic like watching a video on Youtube, the wireless
connection is dropped very often.

This bug report might be a duplicate of bug #779159.
This bug has already been tested against upstream kernel 3.6.0-999- generic
#201210050420 on Friday October 5th 2012. The bug still exists on that upstream
kernel.
Additionnal information (Kernel/LinuxWireless)
- BIOS: up-to-date
- Wireless Access Point: SKY broadband using a SagemCom F@st 2504N, firmware
version 5.23.1a4N
- Wireless encryption type: WPA/WPA2-PSK (mixed mode) TKIP+AES
- MAC filtering: none
- QoS/WMM: none
- Beacon interval: Not indicated, so probably default to 100
- Router internal firewall : No rules set
- Wifi connexion type: 802.11b, 802.11g and 802.11n (SKY uses a mixed mode by
default)
- Only this WIFI device has a problem with the AP listed above
- The issue occurs with other APs
- It is a regression. It was working with Ubuntu 10.04.
- Compat-wireless doesn't provide a workaround or solution.
- This problems occurs in the newest mainline kernel (tested 3.6.0-999- generic
#201210050420)
- ndiswrapper: not tested
I am available to help debugging this issue so please let me know what the next
step is.
Thanks a lot!
BR,
David
