Wifi 6 AX200 160mhz slow download speed

[Skiess]

I have a mini PC with the ax200 wifi 6 card in it that was working with no issues until yesterday.
Today, I noticed that the internet speed was noticeably slow so I checked my speed using ookla's speed test page and found that I'm getting anywhere from 0.07mbps to 43mbps down, with a stable 20~mbps up.
This is the only device that has this low download speed and all my other devices are getting 300mbps down like my ISP provides.

I already tried uninstalling the device and updated to the newest drivers but the issue is still present.

After some long hours of digging the web and various troubleshooting, I found that the issue was with my wifi channel.

Changing the channels around got my speed back to normal range.

Hopefully this method helps anyone else that may be experiencing similar issues.
