I have an HP Pavilion model dv2610ca running Windows Vista Home Premium using a Broadcom 802.11 b/g wireless card and connecting through a DLink model DI524-router. I also have a Dell Inspiron model 640m running Windows XP SP2 using an Intel Pro 3945abg wireless card and connecting through the same DLink router. The HP Vista machine shows a signal quality of "poor" (1 bar on the signal quality graphic) even when the machine is 6 feet from the router, and the speed is shown as 1.0 Mbps. If I move the machine to within 2 feet of the router, the signal quality will improve to "excellent" and the speed will show as 54 Mbps. Also, the HP Vista machine performs exactly the same way at a neighbor's house using a different router (LinkSys).The Dell XP machine shows a signal quality of "excellent" and a speed of 54 Mbps almost everywhere in my house, so this obviously isn't a router signal strength issue. I have done everything that HP asked me to do with the machine and the issue persists. They will replace the Broadcom card for me, but I'm skeptical that it will solve the problem because of the many posts I have seen on the Internet about Vista networking issues.Does anyone have any suggestions regarding this apparent inability of Vista to obtain a high quality wireless signal?

Hello, As this issue is hardware performance related, Im not sure if we can mitigate it just from Windows side. Based on your case, is the drivers for motherboard and network adapter are most updated, its recommended that you temporarily try another model of network card that is compatible with Windows Vista, then test if the functionality is enhanced compared to original one. Cheers, Lionel

Lionel;Thanks for the reply. I have updated the system BIOS and the network adapter driver to the most current levels, but neither has helped. I now have a replacement Broadcom network card being shipped to me from HP. Once I receive the new card and install it, I'll update this thread with the results. If the replacement card does not fix the problem, I guess my next step is to try a different network card.Update: The new Broadcom wireless card has fixed the poor signal issue.
