Hi, I recently "upgraded" from my older Wrt54gs v. 1.1 to the WRT54GS v.2.1 Since this, I have noticed that my daughters PC does not seem to get as good a connection to the router as before. She has the latest PCI card as well, as both the new router and her card were bought at the same time... only 2 weeks ago. Now I have seen talk of version 3's and 4's and that this one has this much onboard memory, and this one yet something else. Is there one version of the router, that is considered the best one to obtain, if so could someone tell me which one that is. I find it odd that you go to a store to buy the latest and greatest of something, only to find out... perhaps the older models might be better. Thanks in advance.
