TalkTalk should work with any router that isn't customised by the ISP such as Sky, usually a Netgear. My brother uses an ancient Alcatel Speed-Touch & gets 7 Meg Bits with TalkTalk.
He lives out in the sticks so WEP security isn't a great issue. I sent him my Belkin N1 Wireless Modem Router that supports WP2 encryption which he is now I think using. I don't need it now as I am on Virgin cable.
adamagain, I'm not exactly sure what the problem is you are having, it might be me not reading it correctly but could you elaborate please?
