Comment 25 for bug 420678

@bertrand

Try connecting in 2.4 Ghz mode (give the 2.4 ghz ap another ssid than the 5Ghz so you can identify them),
"Up to 130 Mbps" setting at the WNDR3700 and
normal "~/ sudo iwconfig wlan0 rate auto" setting in ubuntu.
Works with me.

What does not work see my previous post.
I am considering uninstalling the module from ktp and try the backport package next.
