I have recently built a new low-mid tier range PC with gaming in mind. I got everything set up with a fresh install of Windows 10 Pro I went ahead and installed all of the drivers associated with my graphics card and motherboard using an old USB WiFi Adapter, a TP-Link TL-WN722N. Everything was going fine, until I tried voice chatting with a friend and tried some online games. Horrendous ping, unable to keep a stable connection on top of the voice chat getting constantly cut out.

At first I though that it was just time to grab a new adapter, so I ordered a new one from. NetDyn's AC1200 was my choice, for people were saying it has great compatibility with Windows 10 and issues surrounding the Creators Update. Now it's finally here, and I got a chance to plug it in and try it out.

After successfully installing the drivers it had come with, my problem has been worsened. The adapter is able to connect to my router, but it is unable to hold an actual connection. The little exclamation point in the yellow triangle is not there, but it is unable to reach webpages and other online services. I had even tried installing it with the utility, which is something I don't do, but even the utility does not actually open.

Is this a problem with my computer, Windows 10, or is it just bad luck with WiFi adapters? The oddest thing out of all of this is the fact I can put the NetDyn adapter in another computer, running the most up to date version of Windows 10, and Plug and Play takes over and it's able to reach the internet with no strings attached.

If it is a problem with my build, here are the specs for it.

AMD Ryzen 5 1600
16.00GB Kingston Hyper X
Gigabyte AB350M-Gaming 3-CF
NVIDIA GeForce GTX 1060 6GB (MSI)
2tb HDD ST2000DM006-2DM164
ASUS DRW-24F1ST c

There is not a lot you can change on wifi and since you already tried a different nic card it is not likely a defective hardware issue.

Pretty much the standard things to try. Try to connect to the 2.4g band it tends to have better coverage, it does not have the same top speed as the 802.11ac running on 5g but it is not like you are getting all that much right now.

You can try to change the radio channels to avoid interference. You can also reduce the channel width to 20mhz to try to avoid interference. Again reducing the channel width will reduce your top speed.

The only other thing I can think to try is to use a 15ft USB extension cable and maybe you can locate your nic in a better place in the room.
move your pc next to the router and try it with a cable for a test.

there are probably multiple problems
1) the distance and walls for the wifi signal
2) the router needs to be capable to push far enough a stable signal
3) your network card.

I dont know your situation but a big network cable might be the best solution and believe me.... cable works always best when gaming.

I did give it a try, but wiring a long cable does not seem to be the best option for me. I'd do it as a last resort.

I forgot to mention that I had a previous PC in the same spot this new one is located in. It ran Win7 and has no problem with the TP-Link adapter.
