Good Internet but flakey PC to PC comms
 

Hello I wonder if anyone can help on this one:

For ages now I have suffered from poor and intermittant transfer of files from 1 PC to another. All my PCs have excellent connection to the internet but when I try and swop files between machines I often get partway through a transfer and then I get an assortment of messages such as 'file permission error' of 'network resource not available' or somesuch error.

I have a network based on a Belkin wireless router. 2 laptops with wireless cards and a PC with an ethernet cable. All run XP home.

Signal strength is good.

WEP is on but having it off (ooo-er) seems to make no difference. The desktop has Zone Alarm but the laptops don't...
All my PCs are logged in the trusted zone in ZA......

Anything else?

Please advise if you can! Thanks! :disturbd:
