help!

I know this is the software forum but nobody was in the networking forum, so please someone help...

I have one desktop(vista) connected directly to my router, and three laptops (all windows 7) connected by wireless,

on one of the laptops, im connected to the router and using internet just fine, but im not able to connect to the other computers, the weird thing is when i view the network map, all three are there, but when i open the network to share files it is not,

i have compared sharing settings on all three, everything seems to be the same

ive fought this for a week, :mad

any suggestions:confused
thanks

 

My suggestion is have you done a R&R me First just to see if there is any infection there if not click this link http://forums.majorgeeks.com/showthread.php?t=208809 , also check your device manager to see what errors are showing !
