have you tried to plug it in another usb port?

Yhea, I did.

Also I realice that only disconnect in 5G channel, in 2.4G doesn't.

Well, I know it´s been a long time since the first post but it may help someone.

 

Archer TU2 AC600 V1

 

The problem I was facing was that on 5Ghz, everytime that the amount of data crosses a certain threshold, like 300Mbps on speed test, or downloading something and watching an youtube 4k video at the same time, the connection dropped and i had to disconnect wifi and connect it again. Everything was fine on 2.4Ghz. And everything was fine, even at 5Ghz on my laptop, using this adapter, not the default one.

 

After a few hours lost, it seems that the issue is the tp link driver(that i didn´t have installed on my laptop), and you have to remove it completely from the system and use the windows 10 default driver. To do that (windows 10):

1. right click wifi connection icon on the taskbar(next to the clock)

2. open network and internet

3. change adapter settings

4. right click the adapter and select properties

5. configure

6. select driver tab

7. unistall device and select remove drivers

8. restart pc.

 Windows will install default drivers.

 

If you have used the tp link driver in the past and the revert driver option, then you have to first reinstall that driver and then uninstall it. To do that , after the 6. select driver tab you do:

6.1. update controller

6.2. Check for updated drivers

6.3. install

6.4. restart

After that you can remove the device(do the 1 to 8 instructions above)

 

 

Some options that i use and may help, but didn´t solve my issue(only the driver uninstallation):

 Router options(not every router may have them):

 1. Disable air time fairness

 2. Select 80Mhz only (40Mhz or 20 don´t give higher speeds than 2.4Ghz 802.11n Mhz at 40 Mhz)

 3. Select 802.11n only or 802.11ac only

 4. Change the channel (mine is 44)

 

 

 

 Wifi adapter options (found in the above instructions after 5. configure)

 

Advanced tab:

1. AP force mode BW20 - disabled

 2. Channel mode - 5G only

 3. IEEE802.11h - enable

 4. multimedia/gaming environment - enable

 5. prefer 5G - enable

 6. radio on/off - enable

 7. Roaming sensitivity - disable

 8. selective suspend - disable

 9. Selective suspend idle timeout - 60

 

Power management tab:

Allow the computer to disable the device to save power - unchecked

 

 

And that´s it. It worked for me, it may work for someone else. If necessary remove the device again and let windows reinstall it. Not that i needed it...

I've tried your first suggestion. It's working fine now! Thank you so much!

I seem to experience the same problem, but your tipps did not help/resolve the problem.

On WIFI AC the network crashes/disconnects reproducably when stressing the network, e.g. via internet speedtest.

I switched to WIFI n for the moment, and it seems to be stable.

 

Anybody else having the problem and could find out what exactly causes the problem?
