Change the channel and bandwidth of the router, it may be caused by the instability of wireless signal

Hello
First of all sorry for my bad english, cause it aint my main language, but i try to describe.

My wifi router doesnt seems to be the problem cause i get similar problem in 2.4ghz also.. Same time if i test with my phone speedtest app , its okey I havnt figured out the exact path to fix it, but its something like that --> uninstall tplink usb adapter drivers, unplug, plug the wireless adapter, install new drivers downloaded from tplink page. For me it doesnt work with first time, cause i dont know sure what order i must do it.. i know if driver reinstall works, then i cant restart pc cause then problem 95% starts again. I had that problem with my old wrd4300 router also, then i didnt totaly figuered out what caused that, thought my windows is screwed and i reinstalled clean windows, and right away with fresh windows problem was still there, and then i changed to cable for a week.. After a week i wanted to show my friend the problem and plugged it back the problem was vanished.. and adapter worked till now good, mid time i just upgraded my wifi router.

Windows 10 drivers seems to be automatic for that wifi usb adapter.. its hard to understand what happens when i restart windows, does my manually installed drivers get overwrited with windows own or what is the problem. For me it seems the windows uses same drivers, cause if i dont uninstall drivers then it wont let me update the drivers saying u have same or better ones already.

At the moment i have the latest windows 10 pro with fall update.

Here's an unofficial driver I packed for the V1 model, both use the same Realtek chip so it should work fine! Hope this solves your issue.
