XMPP and ADSL modem-router problem

This is almost certainly the cause of both your account not working,
and 3).  Your router is proxying DNS, and does not understand DNS SRV.
This is an unfortunately common problem, although one which has become
less prevalent in the past couple of years.

You can *try* explicitly setting your DNS server for the host running
Pidgin to an external nameserver (say, that of your ISP), but it's
quite possible that your crapitudinous router will do transparent
proxying and blow up anyway.  You really need to contact your ISP and
notify them that your router's firmware is unacceptable.  They won't
do anything about it, of course.
