So my girlfriend can't get reliable wifi upstairs on her iphone, maybe the bed's metal frame is acting as a faraday cage, maybe the BT HomeHub 3 router is not very good.
Regardless of who's to blame for the wifi issues, the HomeHub's interface doesn't let you change DNS servers - ostensibly for security reasons but as likely to be related to BT's commercial decision to redirect failed DNS queries to advertising web pages. This is hugely frustrating when you are trying to find out if a host is up by pinging it, and the ping succeeds while the host is down, because you mistyped the hostname and were redirected to BT's "spoof" response.
Anoyingly, if the broadband connection goes down, the router starts redirecting all web requests to itself at the address bthomehub.home which causes certificate errors in applications like thunderbird - generally a pain in the arse.
So its clearly time to ditch the HomeHub 3 and get a proper router. Given the ddwrt GPL violations, OpenWRT is the obvious choice of OS.
Although OpenWRT can be put on a HomeHub 3, the current procedure involves a soldering iron. Therefore I bought myself a TP-Link WR1043ND which is supported by OpenWRT and has a gigabit switch - not bad for £50. Upgrading the firmware was a doddle, simply a matter of downloading the latest firmware for my device (http://downloads.openwrt.org/backfire/10.03.1/ar71xx/openwrt-ar71xx-tl-wr1043nd-v1-squashfs-factory.bin at time of writing) and using the router's built in firmware upgrade page! Very smooth.
Its all fairly straightforward to configure via the web interface (and in fact it comes with a pretty much decent configuration out of the box). I connected the bt infinity modem via the WAN port, and set up the PPPoE connection using the password from my homehub 3 router (bthomehub@btbroadband.com). There is no password listed in the homehub 3 configuration pages but it turns out I had to set up a password of "BT" before the connection succeeded. This was the only non-obvious thing I had to do to get everything working.

How did you set up a password?
I set the password in the connection details in OpenWRT (rather than in homehub3 or somehow on my internet connection). This was in the same place as I entered the internet username bthomehub@btbroadband.com in the OpenWRT config.
Thanks for the quick reply. I really want this firmware to work but I am loosing the will to live with it! I have had to reset a number of times, I make the changes you suggest, and click save and apply, at which point it just hangs and does nothing, then I cannot access the router at all with either 192.168.1.1 or 192.168.1.254 and I have reset the firmware and back to square one again. I am sure it is something silly I am doing because I am probably trying to run before I can walk with all the linux code etc....
Sorted it! Thanks for your information.
excellent.
I had the same issue as this.
I fixed it by getting a second BT Router, fiddling with some settings, connecting it to the primary router and using it as a wireless switch
