I did some work on a computer recently that had problems keeping an internet connection. Here's what happened. I turned on the computer and there was no wireless connection. After resetting the USB cable that connected the Wireless G USB Adapter (old linksys that still had the light blue on the box) to the computer the connection came back but only for a moment. I ran the windows connection diagnostics wizard from IE and it was able to find the connection. The connection held for about an hour and during that hour I updated Malwarebytes and ran a scan, it was clean. The virus scanner also turned up clean. After this was done Windows lost the connection. After a Windows reboot the connection was found immediately and it held the remainder of the time I was there. Given that this has been an issue for the client for some time I suggested purchasing a PCI wireless adapter. I'm under the assumption that there is a problem with the (old) wireless USB adapter or possibly even the cable it is attached to. Possibly not enough power?

In the end what I want to know is what else could be the problem?

Edit: I should note that this is related to a desktop not a laptop. If that matters at all.

This question came from our site for system and network administrators.

In my experience, usb wireless adapters are really hit or miss. Sometimes they just will not work with a certain laptop, but will work fine with others. I would say get a PCI wireless adapter - they are pretty much the same price as a usb but you will get no reliability issues and probably better reception.

Thank you for your input. That's what I was thinking too. I noticed that when the USB adapter was working it had a very strong signal. Plus, like you, I've noticed that USB adapters are a hit or miss. – Jason T. Sep 4 '10 at 11:31
