Are there any lights flashing on the card round the back of your PC case? If not, check the seating of the card in its slot and try again.

If it came with a CD, run the installation again but if it didn't, try searching for the driver in Device Manager. It should be in a category of its own in the list.

no lights, i tried the cd and it opened the software and it said that no card is detected but in device manager it comes but but in the other device section, im just mad because i have to keep using my phone for internet and it keeps cutting out so i was hoping that buying this would work but apparently not

Open up the case and pull the card out of the slot. Reseat it, or better still, if there's another slot, try that one.

It takes only a small amount of dust in a slot that hasn't been in use before, to foul up the connection.

ive blown out the dust and tried all the slots my mother board has and it still is not working, is there a way to install it without a software or device manager because i tried both and it didnt work

There things happen and we all do it.

I'm running out of ideas but it should install itself but it's the lack of LED lights that bothers me and makes me wonder if it would work anywhere else. Do you have a friend who'd let you try it out in their PC?

@Saga Lout @jamesauss hello both did you guys able to resolve the issue in the
TL-WN781ND PCI . because I'm facing the same problem and the led on the PCI card is not blinking and the device manager shows the PCI unit as in other device section with the yellow exclamation mark. I've tried the above mentioned steps to fix the issue but didn't help out. Can you help me in resolving this issue.

The yellow mark says it has enough details of the device, drives usually. It could also be disabled so go into the properties of that device by right clicking on it in Device Manager and see what you can make of it all.

Sakthiananth, You should really start your own thread when you need help. Otherwise everyone can get confused about who is replying to who about what.

Hello! I just solved the problem.

You have to make sure that your device and the driver are the same versions. I don't have a CD/DVD drive so I downloaded the driver from TP-Link website. The website redirected me to my region (Asia). When I tried installing the driver the device not detected error would show.

When I checked the version, I found out that I have the EU version. When I downloaded the EU driver and tried to install it again, it worked.

Hope this solves your problem too.
