at beginning i had the same problems; this is what i did and so far it have work for me.

1. Open the installation disk as a folder ( DONT use the auto run)

2. In the foloder of driver , left click setup executable and in the compatibility tab check. to run as Windows 7 compatibility (remember to click apply and then accept)

3. Run the setup and complete the instalation

4. Once the installation is complete, go to the new TP-link utility folder in your system. (in my case was C> program file> tp-link> tp-link configuration utility)

5. An finally left click the TWCU application and set it to run as window 7 compatibility

i had the same problem, this is how i make it work

TL-WN851ND is old and it seems that it even doesn't support Windows 8 or 8.1.
Hard to say if there is any update for Windows 10 in future...

i agree with you !

I have had win10 freezes ever since I installed wi10 and this card. Freezes could be 1 a day or, the worst day, 9 times. Tried the 352 driver from Atheros.eu and that helped somewhat.
However this link will take you to the 355 64x driver that seems to have sorted it for me.

Hope this helps those that are still doggedly using this card.

The card is not in the list, i can

I downloaded and installed the Win 10 64-bit version 10.0.3.456 drivers for the TL-WN851ND but I'm still experiencing OS crashes. Sometimes the system hangs before it reaches the desktop. Sometimes it makes to the desktop but the system crashes soon after that.

I removed the card from the system and the crashes vanish.

I think I might have a bad card?

Any thing I'm doing wrong?

We have purchase 25 TPLINK WN851ND PCI Adapter for ACER PC under the Wifi Network of UNIFI UC-AC-Pro and UC-AC-Mesh, but unfortunately, all the 25 Adapter not supported to the network stating the "Can't connet to the Network",

 

We tried on different platform link windows 8, 10 and 11 with latest driver but not successful.

 

While we have 100 dlink adapter which works fine with the same device and wifi network.

 

Can anyone here help us...or we have to go for RMA for all 25 devices.

 

Please suggest...if anyone have solutions..

 

Thanks
