Trust me, I hate wirless, but a hole in the wall is pointless - I usually have a physical connection my other router anyway, but won't until issues with my old ISP have been resolved (this has nothing to do with the problem at this point).
Back to trying to solve the wireless issue....
No other computer on the wireless has any problems, laptop running off same connection, experiencing low ping from the same room, as soon as this computer is put back into action, again, no problems at all.
Only from the new computer, using most of the same hardware, software, network settings, router config is has not been changed, DNS has not changed, computer picking up the correct IP address, other computers can browse to it, but receiving data is slow.
