ADSL problem... any ideas?

Indeed, it's strange.

It takes a very long time to look it up, and then just times out.  (Despite 
the fact I can easily resolve the hostnames using nslookup.)

Well, I'm going to try and update the firmware, and beyond that, I think it's 
time to try another router to be honest.  Unfortunately, I don't have a spare 
ADSL router to try it with, as I'm on cable here.

Their old router is still there, and I tested it with my multimeter - seems 
that it's actually the PSU that's broken (external wall wart), so next step 
is to try and replace that, but it's a strange one: 6v DC, 2A.

I've only got a 500mA adjustable PSU, so can't really test it with that 'cos 
it'll possibly / probably break it?  (I mean, I'm guessing the original one 
is 2A output for a reason!)

Will try all that.  Apparently it has been factory reset (and appeared to be 
that way), but I'm going to do it again, just ran out of time the other day.

First, I want to update the firmware and see if that helps.

(I haven't run out of ideas yet, just wondered if anyone had ever seen 
anything like it, because I haven't!)
