Good move.

Sounds like a good step/useful longer term tool etc.

But you might start with some ping testing and perhaps other tests?
traceroute? Not sure sorry, but I find ping a good basic start. Ping
one domain, check resolv time, change pdnsd config +  reload it, ping
another domain etc.

Also, you are in a great position for comparative config checking:
confirm that B is good, A is bad, then on both A and B:
 cat /etc/resolv.conf
 ifconfig
 route -n

Just some basic comparison checking of course, might give a clue.

Also, have you checked your router/modem/w-a-p config?

Good luck
