Strange Networking Problem

I have an older computer with a Soltek motherboard. Been using a wireless home network for about six months with everything working fine. I upgraded my video card over the weekend and now I cannot connect to the wireless network. I changed the video card back to the old one, and I can connect to the wireless network again. The video card is a PNY GeForce 5200 AGP 256 Mb.

I have no idea why a video card change would affect the wireless settings. I am using a Belkin G plus adapter and a Linksys router. Also have one other computer connected to the wireless network and it works fine.

With the new video card in place I can connect with a cable, but all I get with the wireless is unable to connect, It sees the network just cannot acquire an IP Address I have no idea what to do

Please help

I have to make some assumptions here:

The mobo has PCI slots,
probably 4 or more,
these are PCI cards.

Mobos have one or more bridge chips. The bridge connects the CPU to a PCI bus. A bridge can handle up to 3 PCI slots. If you have 4 or more, you have two bridges. North and South.

Mobo manufacturers split bridges up two ways:
1,2 and 3 North
4, 5, and 6 South; or

1,3,and 5 North
2,4, and 6 South

Either way, 1 and 4 end up on different bridges.

Video cards, sound cards and network cards are all resource hogs. When cards don't work and play well together, try shuffling them around so you don't get two resource hogs on one bridge. Try video in slot 1 and wifi in slot 4

ok I will try moving the wireless card around and see if that fixes it. So it could be that the new video card places a large enough demand on system resources that it causes a conflict? That sounds like a reasonable assumption,
I will let you know what I find out

Thanks

that worked thanks,

I did look up the resource allocation in the mobo manual, and according to it, the agp slot is on the north bridge and the pci slots are on the south bridge, so not sure why but when I moved the wireless to the 5th pci slot, it started working, was wondering if the problem was not some kind of rf interference

thanks again for the idea
