Wireless router help?

[TzC]

Hi just wondering if anybody could give me a bit of help with this one..

I ordered Tesco broadband and it was activated today, they have sent out my router but someone else has took the package in and signed for it so I've contacted Tesco about this and am waiting on a reply, the problem is I've obviously now got broadband in the house but don't have the router to use it, I do however have an old TalkTalk router (Huawei HG533), an old BT HomeHub 3 (Type A) and also a Sky Hub (SR101).

My question is, would I be able to install new firmware on any of these routers so I can use the broadband connection and if so, how?

Okay I ended up buying another router today ( Belkin Play N600 DB ) got everything connected up but there is no internet connection, I've read that I should change the router settings to log in with my Tesco credentials but it doesn't seem to be working and there is no definitive answer on what the login is exactly.

Could anyone on Tesco Broadband shed some light on this if you've got a spare minute, thanks!
