I just spend many hours trying to track down why my HP Mini wouldn’t connect to my home Wifi network when I set my channel to 13.
After installing varying drivers, I still couldn’t get it to work, so eventually I downloaded thelatest drivers, then I searched the registry for Broadcom, and found 3 entries with a Country setting of US. I changed these to GB, re-booted and my HP Mini can now see my Wifi network on channel 13.
