My son is moving to an apartment where they have no phone, but there is an att connection. he can sign up for u-verse dsl but has to buy the wireless gateway from at&t. The question is whether we can use my 1800HG 2 wire router instead of buying a new unit. That's $100 he doesn't have. He has 30 days to send it back (can't order without it) so if you think the 1800 would work, we can try setting it up. I don't want to spend time on it if it definitely won't work, though. appreciate any info you can provide. thanks.
