Having a lot of trouble with our HH3 all of a sudden only with the wireless connections. My Daughter in law is very good with computers and spent 3 hours with the hub,the tech chat line and a tech support on the telephone who didn't seem to get the point that it wasn't interference or a channel problem but a wireless only router problem. I am so annoyed as i have recently renewed our bt contract otherwise i'd be off to SKY especially as the speed we were getting originally has now dropped from 54 to 18. BT are becoming a joke!
Have you looked at this thread? https://community.bt.com/t5/Other-Broadband-Discussions/HH3-Infinity-Local-WiFi-Channel-fade/td-p/14...

Probably your best option.
you need to check whethger hh3 is an A or B version from sticker on bottom of HH.. the fade thread is for B
Just checked, this is a Type B.
