WiFi 6 on the 5GHz band performs significantly worse compared to 2.4GHz.

Please clear the network settings on your device. Ensure all drivers are up to date, especially for the new AX200. Securely connect the antenna cables and reinstall the latest firmware. Avoid using WiFi Analyzer for channel analysis; consider WiFiMan for mobile devices. Share relevant screenshots of channel graphs and RedMi settings.
Attempted several times without success. One user suggested checking airplane mode as a possible solution.
Review Device Manager for any hidden devices and remove them if found. Do you have an English version of those settings? Regarding the WiFiMan example, the broadcast operates on an 80MHz channel width. Should I set the channel to 42? Also, would it be better to manually set the channel width to 80MHz instead of letting it auto-select?
@Falcon1986 Sure. from top to down: SSID Security (WPA3) Pass Channel (Manual, 36) Bandwidth (Manual, 80M) Signal strength (max power) Wifi 5 backward compatibility (disables OFDMA and BSS Coloring) MU-MIMO Something about easy connect through apps --- The only available channels are 36, 40, 44, 48, 149, 153, 157, 161, and 165 -add- Just to update, I changed my router region to both Europe and Taiwan, no luck at all. My laptop simply won't detect anything but high channels and I confirmed the router does works at 80MHz with my phone using WiFiMan. My bad for not looking this up before but hey, nothing changed on my laptop so I guess they did work just like now before change(?) Spoiler
Check if your device can detect and link with channel 149 at 80MHz, whether it's on low or high frequencies.
I tested 149 80MHz but my phone didn’t recognize it. My laptop did, but it seems to be running at 20MHz instead. I ran iperf3 on both devices (2.4GHz ch11 and 5GHz ch149) and the phone (2.4GHz ch11 and 5GHz ch52): laptop averaged 2.4GHz AX 178Mbps with a 315Mbps transmit link speed; phone averaged 2.4GHz N 112Mbps with 173Mbps. I’m planning to try Ubuntu Live Disc and turn off LAR later. It looks like I can’t disable LAR on Ubuntu 21.10 with the current kernel. Maybe wait for a driver fix or switch to another chip—Mediatek, Realtek, or Qualcomm works.
