Page 1 of wireless network problem!!

hi help please have a cable wireless set up at home 1 pc connects to the router with a cat 5 and 2 others use wireless cards! 1 pc is always at full strength with excellent signal strength! but the other goes up and down all day long! and always totally loses connection to the router! have tried serveral different cards and even different brands but it still keeps dropping out have also tried different pci slots in the mother board! any clues please!! could it be a dodgey mother board?
thanx for looking
dug

where is this pc in proximity to the router?

don`t forget that walls / furniture / electromagnetic interference will affect
the signal strength.....if you have no asmovement options, consider hardwiring
the pc with Cat5 cable.

...is that gasoline I smell?

What Ste said.

You may want to also consider adding another wireless access point if range is the issue.

Try moving the PC with problems next to the router for a period and test to see how the wireless behaves then.

thanks for the advice! the pc is 1 floor up directly above the router maybe 3m, the other pc that use the wireless is further away and that has no problems! think i might just hardwire it cos its driving me mad keep losing connection!!
Thanx all
