Sorry it's long! So, just over a month ago the processor in my old computer died a fiery death, it wasn't such big deal really as I had been planning on upgrading for a while. I did a little shopping around and settled for an Athlon 64 3000+ with a WinFast NF4K8AC motherboard, a Sapphire Radeon X800GT (PCI-e) and topped it all off with an extra 512MB RAM to give me a total of 1gig. Installing the components and setting up Windows XP went fine and initially all was well... Approximately an hour after re-installing all my security, games, MP3s etc I lost connection to my home wireless network. Soon enough the network re-connected but my computer was no-longer receiving packets. Here's a description of my network setup: Standard DSL wall box connected to a "server" pc via USB --> this computer is the gateway for our home network which serves another three computers by means of a Belkin wireless network hub. After a couple of re-installs without any success at stabilising the connection I started to faultfind. First was the network card: I tested another 2 functioning network cards in my computer after swiping them out of the other 2 computers on the network, both failed to establish a stable connection. Further testing proved that my original network card was not at fault either, it performed excellently in the other computers on my network. I removed the sound card and gave it another try, no problem there. So I decided to relocate closer to the wireless hub to eliminate the possibility of it just being a wierd blackspot, again no luck. Wondering if it was a graphics card problem or pci irq conflict or something I got hold of a PCI Geforce MX 4400. No problem there either. So I called over some techys and let them have a go and they're baffled! So out of desparation I've gone back to using network cable between my computer and the server (no problems so far) but only as a last resort and a temporary measure at that. Any suggestions? Also, might upgrading to a wireless router help? I'm not looking forward to running that network cable through the wall, under the floorboards upstairs and into the spare room.
