Not connecting to 5G router

[kanari212]

Hello, 

I got recently samsung A20 S, and while trying to connect it to my 5G router , it wont appear , meaning the name of my wifi wont appear. So am unable to connect. 

In same time all my other devices are connected perfectly. 

So is there I can do so I could connected my A20 S

Dear, I am not 100% sure whether galaxy A20S Supports 5Ghz Wi-Fi or not (I am not talking about 4G or 5G routers, what I meant is the frequency in which Wi-Fi operates).

Usually Wi-Fi works in 2 bands, 2.4Ghz & 5Ghz.
All smartphones will work on 2.4 Ghz while 5 Ghz is supported by some devices only.

Go to your router setup page and make sure its in 2.4 Ghz, or if your Wi-Fi supports dual band, then turn on both the bands so that devices will automatically connect to the desired band.

got it thank you, it seems so far that A20S not supported by 5G band But when I change the router to 2.4 it did show up and connected.

the Qus now if I change the router to 2.4 would it effect the speed ?

Yes, It would slow down your speed ! An expensive phone like Samsung S9 does not support 5Ghz!

Galaxy S9 supports 5GHz WiFi. Mine is connected to it.

Same with Galaxy m11

I think there is a dual mode to activate both 2.4 and 5 Ghz.
the benefits with 5ghz is you can can better speed but the range of the signal is shorter while the 2.4 ghz uts range is longer but the speed may be less.

how can I activate it on Samsung?

[Ahmed6]

you can activate the dual band on the router settings page.
check on the rear side of the router the login page address + user name + password
