Hi, I found this forum a while ago & it looked like a good site to boomark. Now it might come in handy. I have looked over this forum and have seen some similar to my problem but not the same. Maybe someone can help me with it. I have a HP Pavilion a810n that originaly came with Win XP. Almost two years ago I upgraded to Win7 Pro. It ran fine but it wouldn't connect to the net. It was telling me about my network adapter wasn't right. I took it to a pc shop and they said I needed a NIC card. They put a used one in (that's what they told me they did?) and it worked fine. Recently I had to re-install the Win7 OS. My pc will not connect to the net again. This is what it's telling me: (( Install a driver for your network adapter "Windows did not detect a properly installed network adapter. If you have a network adapter, you will need to re-install the driver." )) The pc store that I took it to has since closed down. I am tryin not to take it somewhere because $ is tight and I just need pointed in the right direction. That NIC is still in but I'm thinking it might just be the driver? It looks like the NIC is made by Agere. I looked that company up but it merged with LSI Corporation back in 07. I can't find it at the site. I'm not sure what all info I need to put up but here is some basic: AMD Athlon(tm) 64 Processor 3300+ Motherboard: ASUSTek Computer INC. Chipset Vendor SiS Chipset Model 760 When I go to device manager, I get "Unknown Manufacture." My sound says the same thing but getting on the net is my main goal. I did use that one site that someone suggested to find the VIN/DEV. I'm not sure what it was telling me. VEN: 1039 DEV: 0900 Any help would be appriciated.
