My computer (the one I'm typing on) is a windows 7 (x86) connected via ethernet to a router acting as a switch. That router is connected to a router in another room, which is then connected to the modem. The problem is that buffering youtube videos is, for some reason, slower on this computer than a windows 7 (x64) laptop connected to the same router via wifi.
I don't have any firewalls (not even windows firewall) enabled, nor any anti-virus on this computer. I know this, and networking questions in general, are difficult or impossible to diagnose without a decent amount of back-and-forth between the person with the problem and someone with the experience to solve it, so what I'm looking for is software that might help me track down the issues at hand. Network monitors and the sort. Or, if by chance, someone knows what might be causing the problem, please let me know.
The router this computer and the laptop are connected to is an actiontec gt704wgb, and the one in the other room is a linksys wrt54g v5 router.
