The above CPU, RAM and OS is not for the system in question....I didn't know how to change the info after I got into the preview of the post...sorry.....but the Linksys WRT54G is the service router of the network that I refer to below..... The problem is at my neighbor's house. They got a Linksys WUSB54G V4 adapter on one of their computers. That computer is running Vista. That adapter has been working fine for 8 months or so, then all of a sudden last week it stopped working. I went in the Device Manager and there was no adapter....nothing under Network Adapters. I went to the Linksys page and down loaded the driver to a flash drive. I installed the driver thru the wizard. After that I was able to log on to the network and had good internet access. The problem now is......every morning I have to go thru the same thing after shutting down the computer at night. One of two things happen: the adapter is not found or there is a yellow "!" mark which alerts me to faulty drivers. So.....what am I looking at here.....how come I can't get these drivers to stick after installation...?? Thanks to any and all who take the time to reply. /r Bill

It sounds like the driver isn't making it to the system32 folder or wherever it's supposed to go. Copy it to the C: drive & run it from there without the flash drive connected. How do you know when a politician is lying? His mouth is moving.

Thanks for the reply. I never thought of that.....but no matter it's too late. Got a call from the neighbor who said he's taking the computer into a computer shop this morning; gonna let them deal with it. He said the guy at the shop will update the computer, install Windows 7 and check out the router/adapter. The neighbors are in their late 60s and early 70s....raising a grandson who's all over the computer as a gamer. I kept my mouth shut....you can only do so much. Thanks guapo for the reply and everyone else for looking..!!
