Wireless network adapter problem

[lsvet1]

I have a problem with wireless usb network adapter(Tenda W541U) and therefore I can not connect to the internet. In network and sharing center adapter is listed as disabled but when I try to enable it says "Enabling... then Enabled" but actually after that it is still listed as disabled. It is enabled in Device manager, I also reinstalled the drivers but problem is still there. I'm 100% sure that there is nothing wrong with wireless adapter, I tested it on another computer and it works perfectly. I suppose there is something corrupted in registry cause yesterday it worked and today when I turned on the computer it didn't work anymore. Operating system is Windows 7 x64 Ultimate.

Maybe it needs a software to use. Does the device come with a software utility?

 

[lsvet1]

yes, software utility is installed it comes along with the driver, but because wireless adapter is disabled I can't change any settings in the utility.

Have you tried to uninstall the adaptor and the software completely then reinstall it yet?

You may have also lost a file somehow, try running sfc/scannow into the command prompt run as admin.

Now I completely reinstalled but wireless is still disabled. I ran sfc /scannow and no integrity violations were found.

only install the driver leave the utility out of the mix they usually just cause more trouble windows can handle management of wireless devices just fine

here is a link to the download page for that but they don't list OS versions kinda lame W541U V2.0 54M Wireless USB Adapter-54M WLAN-Tenda

well what do you know another Ralink chipset in that good luck with that

 

[computersplus]

does your motherboard have an Nvidia chipset?

 

[lsvet1]

Well i did install only driver before but again no luck, it's kinda weird that it worked before and the adapter itself still works with same drivers on other computer that also have windows 7 x64 installed.

 

[computersplus]

these adapters with the ralink chipset have been giving people fits try changing the MAC address of the adapter or look at the settings and see if it's all zeros

 

[lsvet1]

I ran ipconfig /all and it weren't listed there, with getmac command the device with the same mac address was shown but with no name

here is the screenshot

Lets not discount that you may have a dud wireless adapter. It's not recognised by the system from your ipconfig details. Check in BIOS.

 

[lsvet1]

All settings in BIOS are default except speed of processor which is a bit overclocked, obviously I'll have to reinstall windows

Doubt this. He said it works fine on his other Win 7 boxes.
