Realme x2 pro doesn't detects 5GHz wifi routers

My brand new Realme X2 Pro is not detecting my 5Ghz wifi routers. I tried with another realme model also and that also doesn't detects this 5Ghz Wifi router. I tried searching with various other brands phones like Apple, OnePlus and Redmi which shows up my 5Ghz router without any issues. Seems like it's a software problem. Please look into the issue very seriously as many industrial Wifi Routers work in this 5Ghz band.
You are on custom ROM or on realme UI ? What channel your router set to. Which country you use your phone . When I am on custom ROM I can not see routers that have channel over 64 but on realme UI I can .
No problems here and I'm only connected to my 5ghz band,
On EU model with latest RUI update
i hava same issue with you. And i fix it with this severals way:
1. Turn on air plane mode
2. change your phone region to Singapore
3. restart your phone
4. then try to connect to 5Ghz wifi

Redmi 9C connected to wifi but no Internet

Sorry for posting in this thread, but I cannot find a Redmi 9C section. I just bought this phone and I'm trying to use it in my network. I use Ubiquiti products (16-port switches and a bunch of AP access points). I connected the phone via wifi to my network and it has no problem for a while until it just doesn't have Internet connection. It stays connected with its IP address intact but for some reason it cannot seem to reach the Internet. The workaround is to simply turn off the wifi module and turn it back on. It's randomly happening and the workaround is very annoying.
I have a couple of other mobile devices (iPads, iPhones, Android phones, Windows laptops, etc.) and I never experienced the issue with these. I tried connecting the Redmi 9C to all my wifi networks:
Guest wifi with captive portal
Main wifi with RADIUS authentication
IoT wifi with regular WPA2 personal authentication
I tried resetting the wifi settings of the phone. I tried reinstalling the latest MIUI fw/sw.
and the result is the same, every time. At this point, I can safely consider that there has to be something wrong with the phone. I'm not sure if it's because of the MIUI 12 update because I updated the phone to the latest firmware as soon as I got it out of the box. Is this a known issue with this phone? I have another Xiaomi phone (Mi Mix 3) on the same network without any issues.
Any ideas?
Mods, I found the Redmi 9C section and I posted there. You can delete this thread. Thanks.

Redmi 9 Prime hotspot problem

Hello all
I am facing a problem with Wifi hotspot. When I am turning the Wifi hotspot ON with security set as WPA2-Personal,
the phone isn't detected by TP Link USB wifi adapter. But as soon as I remove the security, the phone gets detected.
One strange thing I noticed is that when the phone is connected to some other Wifi, the phone gets detected
by TP-Link USB Wifi adapter.
Please note that I have already set settings put global tether_dun_required 0.
Please help me fix this issue.
Specs :
Redmi 9 Prime
MIUI Global 11.0.6 Stable
Android 10.
