Recently bought a WRT54G wireless router from a guy on EBAY.. it's a version 2. Finally got it hooked up and have configured 2 desk top computers and 2 laptop computers to it.. Recently, I've noticed that the respond time to my clicks while navigating the internet has slowed considerably. I've thought it was just congestion at a certain time of day but it's now all the time I have cable internet from Wave Cable so I trhought it should be a lot faster than what I'm seeing. I've run a diagnostic test on my computer and it says everything is operating at 100%. I have a pentium 4 from Dell. I've run all the spy ware programs I have.. I've run Hi jack this, I don't see anything out of the ordinary there.. I've read about router upgrades.. never done that.. do I need to? Any help would be appreciated.
