If you obtain a replacement router you are not limited to the Thomson / Speedtouch rubbish - you can get a more normal device which has a "normal" UI rather than the wierd Speedtouch one!
Beware of ISP customised ones. These devices are not expensive - look on the likes of Amazon etc as well as eBay.
I could never find my way round this!
