[issolom]

hi thanks very much for reply

"then i tried to use the device manager and setup manually", can you tell me what procedure you used to install the driver manually? Is the cable disconnected when trying to update the drivers? Have you scanned for virus as well?

i opened the device manager and then choosed the yellow mark indicating new hardware under the category of network adapters and then choosed update the driver and after that i manually searched for the folder which contains the driver of the lan network card but it said that windows cannot find the proper files for the driver i also tried the automatic search and the same occured
i have scanned for viruses many times using kasper sky 7 up-to-date till 8 ocotber 2008
thank you very much for your concern
