Other wireless clients work OK connecting to the same Wi-Fi network?

Did some research then decided the link you proved is safe, so I installed the driver. All seem well but will need to use the computer for next couple days to see if everything is fixed.

Every other devices in my house connect to internet 100% without any problems, it just my machine. Hopefully the driver you proved will help, thanks!

Hello all,
I am using Window 7 and I had no BSOD problems with my coputer for few years.

I boought two TL-WN722N and all have the same problems !!! Especially after few hours of working I had disconecting issues and it disconneced totaly (windows dignostic suggest to plug in USB cable). Control light is no flashing anymore and acces to all network opitons is blocked. When I used it my computer started to have BSODS, problems with shooting down which I had never before. Typical unpluging device procedure is helping for a short time and device is complitely blocked. I reset this card and it working ocassilnally only for a short time. It's stay unpluged with no reaction and reset commands after 2-3 disconnecting stop working too. Only hard reset of computer is helping. I need to push my reset button to have effect becouse all acces to network is blocked too. I had old PCI wifi card and there are no shuch probles at all. Whats more connection is very bad and instable even if signal is in exellent 80% status. Pings are 90 (I had on my old card 20) and it very often start to loose packets before crushing at all. I am total dissapointed of this!

TP-LINk crew. Fix this total and evident bug!!!!

All 2 devices had the same problem. I many times forced to check my provider connetions and my main router status and this was only this device connection problem.

Very interesting that reinstaling drivers always magicly help for a wile! I had issue that one of this device had not start to working at all even after computer reset and only drivers reinstal make possible to force it to work once again. So I think Win7 have a prblem with this device with switching off, unpluging device and too often loosing connections to main router, higher then standard pings mixed with loosing packets or even hanging system.

I think drivers support is here very big problem. There are no typical files for automatic install as normal .exe and there are no new versions with similar problems fixes.

I will try Atheros drivers and I will tell You if it's start to work better.

Thank for a llink!

Hi again,

PolishFactor seem to sum up most of what I'm been getting but with more details.

I come back with the result of few days of testing, I just been downloading few things. So far, over the last couple days, I only had few disconnects here and there but nothing major like I can't reconnect or shut down my computer with BSoD. So the third party driver seem to fix it, thought not 100% just yet but it is a massive improvements. Those few disconnects I had only just resolved by itself without me having to fix it. I will carry on with what I'm doing and if anything happened I will report to here. But thanks for the third party driver!
