Edit 2: Solved, I think! Made sure my firmware was completely updated and made my Wifi 6 network only accept wifi 6 adapters. Seems to have worked. Instant, fast download speed. Not sure if it was the reboot, the firmware update, or the excluding any other types of connections, but something worked, at least!

Edit: Update! Just tried to connect a phone to my Wifi 6 network, my second 5ghz channel, and it's getting the same slow internet speeds, so it's a problem with my second 5ghz, AX network on my router, not any particular device. Any ideas?

I also connected my upstairs desktop wifi to my "standard" 5ghz network and am able to max out my wan speeds again, so that specific wifi network seems to be the problem. I'd really like to be able to utilize Wifi 6 if I could, so any advice would help.

I recently picked up a generic Intel AX200 card to go along with a Wifi 6 router I recently purchased (RT-AX92U mesh, 2 routers) and am having a puzzling problem with internet speeds.

I've got decent signal - something like -50dbm, and file transfers within network seem to be as fast as I'd expect given hard drive speeds, but multiple internet speed tests are giving me ridiculously low speeds of under a mbps, sometimes up to 2mbps, but nowhere near the 200 that I'm getting on the wired network.

The odd thing is that SOME internet speed tests - Ookla and Comcast speed tests, I believe, are giving me decent speed measures - about on par with wired, but streaming Netflix kind of betrays their results as it's not working well at all.

One would think that I should be able to get that speed over the internet consistently because I'm getting MORE than that within the network - is there anything I may be overlooking that would cause the issue?

So far, the main troubleshooting steps I've tried to take are basic settings changes - I tried to install the Intel drivers separately, turn off QoS, check connection to and from router, make sure the settings aren't wacky on Wifi 6 channel.

Thanks ahead of time!
