Just a heads up really, in case anyone here is similarly affected.\n\nThere seems to be a problem affecting users of BT Home Hub 3s. The WiFi\ndownload speed fades to a fraction of normal (e.g. between 1-2MBit/s\nrather than the normal 20+Mbit/s). Wired connections work at normal\nspeed so it's not a problem with the Broadband line itself. Restarting\nthe HH3 or resetting to factory defaults restores the speed but it then\nfades away over a period of some hours.\n\nNeedless to say, reporting the fault to BT Technical Support gets you\nconnected to offshore and supplied with somewhat useless suggestions\nsuch as :\n\n(1) I think there is a fault on your line so I've asked for your line to\nbe checked. Two days then pass while the line is checked. Your line\nchecks out OK. I had already checked that the bandwidth on the line was\nstill good.\n\n(2) Please change the channel as my colleague requested (the colleague\ndidn't request anything). I had already tried changing the channel (from\nsmart mode to a fixed channel number) and it had the same effect as\nrestarting the HH3 - speed goes up to normal, then fades over a period\nof a few hours.\n\n(3) Please suggest a time that we can call you for an "interactive\nsession" because it is a complex issue. I suggested two days/times and\nthey didn't call. I don't know what they intended to do - perhaps ask me\nto do something as complicated as restarting the HH3 (which would\nincrease the speed for a few hours), which of course I had already done.\n\nThe daft thing about this is that the HH3 is smart - it homes in on the\nleast congested channel, and I've observed it on various different\nchannels (mainly 1,6 and 11) over a period of time. BT's help page even\nadvises against switching off smart mode!\n\nThis thread on a BT Community Forum is where most of the discussion on\nthis issue is taking place:\n\n[URL]https://community.bt.com/t5/Other-Broadband-Queries/HH3-Infinity-Local-WiFi-Channel-fade/m-p/1455707/highlight/false#M104193[/URL]\n\nThe moderators, who are possibly not offshore, seem to have a degree of\ntechnical expertise (sadly lacking in the main BT Technical Support) and\nappear to be taking steps to sort it out. From what the posters on this\nForum say, the problem started a few weeks ago, so perhaps there is an\nage-related hardware fault? It's not obviously firmware as the firmware\nis dated August 2013.
