I installed a Linksys RT31P2 broadband router and WRT54G wireless router to my Dimension 4600C. I have cable internet which runs from the wall into the RT31P2, then from the RT31P2 into the WRT54G, then from the WRT54G into the Dimension. I run my telephone (Vonage) from the RT31P2 because it has two telephone ports, and i use the wireless from the WRT54G to surf the net on my Inspiron 600m in another room. Although it took me a hell of a long time to set these two routers up to work together, i finally accomplished that. But here's the thing... now my main computer (i.e. the Dimension Desktop, the one that is connected to the WRT54G router via the RT31P2 router) is incredibly slow. Not just when using the internet... the whole computer is "gummed up" whenever i run any type of application. This was not a problem before i installed the routers. My remote computer (the Inspiron laptop, which uses the wireless internet) works perfectly with very fast internet, and my telephone service from Vonage is fine. If anyone could offer any assistance i would be tremendously appreciative.
