Hi,
I'm having problems with an Intel Corporation Wireless 7260 (rev 6b)
adapter running in ad hoc mode. Any ideas?
The hardware is Getac F110 tablet, Core i5 Haswell. I've tried to use
Linux v. 3.13, 3.14, 3.15-rc5+ with microcode v. 22.24.8.0 and
23.214.9.0.
What I'm trying to do is:
# iwconfig wlan0 mode ad-hoc essid xxx txpower 16 channel 11
# ip link set up dev wlan0
# sleep 1
# iwconfig wlan0 mode ad-hoc essid xxx txpower 16 channel 11 rate 6M
# sleep 10
# iwconfig wlan0 mode ad-hoc essid xxx txpower 16 channel 11 rate 6M
wlan0 works in ad hoc mode after "sleep 10" and subsequent iwconfig.
