Hello everyone :)

 

A few months ago (October if I'm not mistaken) I bought a wireless USB adapter to use on my desktop computer (our backup computer) since we got a router and that computer does not have a wireless card. I installed it, it worked fine on that computer and I could use the internet without any glitches, up until the middle of January. I went to turn it on to update windows (runs Windows XP) and the computer does not recognize the pen drive (doesn't show up on My Computer, the light doesn't even turn on). I thought it had just died but my personal laptop recognizes it and there's nothing wrong with the desktop usb ports because everything I plug into ANY port works perfectly.
I uninstalled the adapter software and installed it again. And again. Nothing. I tried it with a USB cable, still nothing. Restored the system, also nothing. Is there anything that can fix this problem or should I just buy another one? What if it happens again?
 

The wireless usb adapter is TP-Link TL-WN727N 150Mbps, I'm running Windows XP.

 

Note: said computer will be used to teach my father how to browse the internet, he's clueless about it. I was out of the country for two weeks and he told me he turned the computer on and it didn't have internet, I have no idea what he did, or if he even did something to try to turn it on.

 

Thank you in advance :)

I assume you have tried the adapter in the other USB ports.

 

Are there any yellow exclamation marks in Device Manager under Network adapters?

 

If there aren't any, download USBDbview and run it in an admin account. Then look for all instances or your adapter. Right click and select Uninstall. Do this with the adapter detached. Reboot, then plug the adapter in and see XP recognizes it. You may have to reinstall the adapter driver.

my usb network adapter was acting weird for the longest time. i had to use the ipconfig and netsh commands to reset /release/renew. then i found out that if i have a lan cable plugged into the access point, it won't work. but the best bet would be to clean uninstall it and reinstall. it was working before, but got corrupted somehow maybe?

Thank you so much! This worked perfectly. Typing this reply from the good 'ol tower.

 

ps: And yes I did try all the ports, all 7 of them!
