Why The phone Can't detect 5 Ghz Wifi?

The phone can't detect 5Ghz wifi in every day use. When I enable airplane airplane mode and turn my phone off and on again, it detects 5Ghz wifi and connects to it. But when i go out of range and come back or turn wifi off and on again, it cant see or connect 5Ghz wifi untill i repeat the whole process again. 2.4 Ghz seems to work fine. The phone is currently running android pie. The issue was also on Oreo. Is this a hardware issue? And how can i solve this. :(

I have done factory resetting and also tried changing wifi channels and resetting router. The 5Ghz wifi works fine with other devices.

Change the region in your router. After switching to a new region, you'll see new channels have appeared in your 5ghz channel list. Switch to different channels, save the settings, reboot your router and see if your phone can detect the 5ghz WiFi or not. If your phone can't detect then switch to another channel.

I too have this problem where i can sometimes connect to 5ghz and sometimes it doesn't connect no matter what. I have 2 separate ssid for 2.4 and 5 ghz , all the other devices in my home are connected to 2.4ghz , only my phone and my laptop connects to 5ghz.

Turning off/on mobile phone doesn't work for me neither does airplane mode. But what did worked for me(atleast this one time) was disconnecting my laptop from 5ghz so that no device is connected to 5ghz, then connect my phone with it and it works! Once my phone is connected i reconnect my laptop to 5ghz.

Someone on the internet with the same phone said to make sure your APN and SIM card are working properly.

You could also try taking out the SIM card, maybe its conflicting with your public wifi options.

Try and do something with both things I said and get back to me.

I have checked the apn, reset it. Internet on mobile data works alright.

I have tried takin out the sim card too. But nothin happened :(

This might be a system bug, right?

@shatil

Hmm. Try the APP " WIFI ANALYZER PRO"

You can also try making separate SSID in your router settings. One for 2.4ghz and the other 5GHZ for your phone.

Another person suggested the router settings and it seemed to fix the man's problems.

I will send a thread to the post, in theory basically your network is too crowded, in which needs separate ones. Pretty simple to understand. Try this for me.

And the fact you have done system restores etc. I really think its some from of connection issue between the Phone <-> Router ---- not necessarily a system bug. I think those router settings will fix it :)

I have set separate SSIDs already. Changed router settings according to that thread but the frequency options in my router is only from channel 36-48 on 5Ghz. There is no option above 48.

I have also changed 2.4 Ghz settings and set a less crowded channel.

Installed the app but 5Ghz SSID still not there. :(

Still the issue isn't fixed yet:(

Hmm. Try downloading the app, 1Tap WiFi Repair Lite.

Can you not try 36- 64? Or are you saying that is the highest you can do?

A person with that phone said that fixed his issue.

Best you can do is keep looking up solutions online. Because at this point thats what I'm doing and so many people have the same issue with your phone, as in they have the same phone.

Only thing I can think of besides that is waiting for an update. A majority are saying that, a hardware problem as you stated. Some are saying its a router thing. But at this point, I doubt its a router thing. I'm also guessing you have tried many different options on the router as well.

And in your WIFI advanced settings, you do have the option search for 5GHZ only?

さんによる

There isn't any option of selecting 5Ghz only in advanced settings. And my router doesn't have any option beyond channel 48. I am eagerly waiting for an update ( Really optimistic for a fix). I have also sent a feedback to xiaomi regarding the issue.

I had the same issue. I went to my router settings (Netgear router), and changed the channel from auto to 36 for the 5g network. After this it became visible on all devices. Try different channel numbers and see if it works.

  1. Reset your router
  2. Configure using Singapore Region
  3. Set 5GHz Channel from Auto to 36
  4. That is how I got it working in my Samsung Galaxy S10+ , using Xiaomi Mi 4A Dual Band (Non-Gigabit Edition) Global Firmware Router.

I have the same issue with samsung galaxy s21 ultra . 5ghz works once airplane mode is turned on, then restart phone and turn on wifi before disabling airplane mode . Guys what i have observed that band one which is channel 36to48 is where u have issues . My phone in normal, can see 5ghz wifi which are on band 149 and higher . With this restart sequence i am able to connect to the 36_48 channels. That also till i m in range . Once out and back everything has to be repeated . Its strange as to understand what is conflicting. Wifi and sims are totally different things and should not be interconnneted in anyway. All those who have mentioned the problem above should try channels 149 and above . Its something to do with region wise softwares by phone companies . Enabling and disabling channels as per country law.

I am using a mesh wifi6 system (deco x20). And dont have option to select channels.
