I'm using a TP-LINK TL-WN781ND Wireless N card with an AR9285 chipset and an ath9k driver on Xubuntu 12.04.1 with Network manager.

'iwconfig wlan1' shows that it's using a bit-rate of 54 Mb/s. Is there a way (e.g. through an 'options' entry in '/etc/modprobe.d/ath9k.conf') of forcing it to use mode N? My router is doing 'Mode B/G/N Mixed'.

If the driver supports it, you could try sudo iwconfig wlan0 modu 11n, and for the module options, have a look at modinfo ath9k. That said, there is probably a reason it uses 11g. Are there 11g only devices that connect to the router? If not, try disabling the mixed mode on the router. –  mikewhatever Oct 7 '12 at 22:42
    
The 'iwconfig' mechanism would probably break any existing connection set up by Network Manager. And 'modinfo' doesn't show any 'parm' parameters that look appropriate. So I've disabled mixed-mode on the router .. but that's likely to upset some of my visitors in the future. Any other suggestions? –  Graham Oct 8 '12 at 7:09
