As u all know S8+ have Wi-Fi 802.11 a/b/g/n/ac, but Mine S8+ is not showing 5ghz wifi band.
Please help me out that how to resolve this issue.
It's not clear what are you asking here. Almost any phone can connect to a 5Ghz network, your router must be dualband
I have cisco E4200 dual band router with both 2.5ghz and 5ghz frequency. As u say almost all phones working fine but mine s8+ even not detecting or showing 5ghz band network. I tried well like to add munually network but issue still there.
I too have a S8+. However, it will not detect my 5G wifi, though my Galaxy J7 can both see and connect to it.
Both are running Android 8.0 and Samsung Experience 9.0
Pls advise
I have the same issue. After I tried and checked the device in many ways, I finally found out that it is related to the mobile signal. If you turn off the mobile data off, 5GHz will show up on your wifi list.
This is how I do.
1. Turn on the Airplane mode.
2. 5GHz wifi shows up. Connect to the AP.
3. Turn off the Airplane mode. The 5GHz AP remains connected.

Change the channel setting for you 5GHz to something near 153. S8+ does not see some lower channels.

Finally!!!!!!!!!!!! I can connect to 5GHz network.
THANKS ALOT Gaujvsjks!!!
I am using Jio SIM in India which uses the VoLTE technology, so maybe that's the reason my S8+(SM-G955FD) won't even show any 5GHz networks in the settings.
Thanks!
Thanks
:good:

Hey everyone,
So I've been expernecing this problem for over month. Basically im connected to my wifi on 2.4ghz and suddenly my connection will drop and I check that its now connecting to 5ghz but it doesn't actually connect to it its just keeps connecting and disconnecting every second until it finally connects back to 2.4ghz. And then after few minutes of strong connection ill drop again and same thing.
Im only experiencing this at work. There isn't 2 different ssid for 5ghz or 2.4ghz just one ssid, I was able to find out that they are using dual band router so I can't change anything the router part. is there an app or some setting I can toggle with to enforce 2.4ghz band only? Ive already turned off smart switch and scanning but problem still here.
Thanks in advance!!
I have been having this issue for a while, no one was able to help me so far...
I can't find nor connect to 5GHz networks at all, recently, I found out that if I turn airplane mode ON and then I enable WiFi, I can connect to 5GHz networks...
WiFi ON + Airplane mode OFF (location status doesn't make a difference)
5GHz networks can't be found
View attachment 4851435
WiFi ON + Airplane mode ON (location status doesn't make a difference)
Device can find and connect 5GHz networks, and it remains so as long as airplane remains on and I don't turn wifi off and on.
View attachment 4851437
Other notes, already tried the following:
- Remove the SIM card, no difference
- Reset network settings, no difference
- Change location status on/off, no difference
- Played with bluetooth status, no difference
Pleaseee help

Hi! My phone doesn't have any problems with 5Ghz wifi. Did you try to connect to another wifi? There are some advices about changing wifi chanel in your router (see last 4 posts):

thanks, I have tried the suggestions, still no luck, as I said, 5GHz networks do appear if I turn airplane mode on and wifi on...
i am using a router which broadcast both 2.4ghz and 5ghz band using single SSID. how do i force my phone to only allow to connect to the 5Ghz wifi network. i cannot turn off the 2.4ghz band as there are other devices in my house that only support 2.4ghz or do i want to split the bands into 2 SSID.
Thank you.
i was able to split my router to 2 different SSID for both bands
In the past there used to be an option in advanced wifi settings that made the 5GHz "preferred" but Google took it out for some reason.
The disabling of the 2.4 GHz or having 2 separate SSIDs might be the only way right now (not sure for a rooted phone tho)
Sent from nowhere over the air...
Yes not sure why did Google remove that option. Any hidden secret code i.e. *#00*# etc that allowed us to make changes to network setting.
Some routers have band steering which will force devices to 5ghz if supported while keeping 2.4ghz for devices that can't.

I turned off Auto Connect on my 2.4ghz, so it stays on 5ghz all the time.

Mine only 1 ssid for both band. Seem like there is no solution and i had to split the bands into 2 ssid.

I only have 1 ssid. Like I said, I turned off Auto Connect for 2.4ghz so it always stays on 5ghz.

thanks, but for me both the bands are broadcast into one SSID. which means i can only find one wifi connection and the wireless router will change the band connection based on the signal strength when i am moving around the house. it will change the connection to 2.4ghz when i am in some place where the 5ghz connection is weak. why i wanted to stay with 5ghz when the connection is weak because it give a much higher download/upload speed compare to the 2.4ghz connection which somehow got much weaker internet speed to the extent of unusable.

Buy a new router where you can separate them and then disable or turn off the 5ghz connection
Looks like this is quite an issue for N2Us. I have a 4 year old iphone and it stays connected to 5GHz in the same place and N2U reverts to 2.4. I have band steering and have been really well on all other devices. Issue lies only with N2U.

Mine can separate them but since it is only affecting my phone, I hope the change can be on the phone instead. By separating them, I will need to configure all those devices that can only connect to 2.4ghz. e.g. ring peephole
Did you solve issue? Same problem here :/

Errr...you actually DON'T have one SSID but 2. The band is appended on the name and they are actually 2 different WiFi networks with different names so you could turn off auto-connect on the 2.4GHz one
I use the Wireless Mac Filter on my router to block 2.4Ghz Band for my phone mac address, so the phone can only connect to 5Ghz
If you are using a Samsung phone in the advanced settings for wifi, turn off use randomised MAC address and use the phones actual MAC. This fix has been tested on Netgear routers and works, phone will join the faster 5ghz and still be able to switch to 2.4 if you are at a distance from the router

This is what i did .
(It might give you an very easy option /idea .)
My current setup is a Nokia fibre router that has 2.4 ghz and 5 ghz bands
I bought a reasonable priced wifi mesh 'TP DECO M4 "then
connected it to my fibre router ( ethernet cable )
The TP wifi mesh comes with an Android app fo configure it (settings )
All i did was swicth off the 2.4 ghz band in app, for my TP decom 4 model .
So if i wand to use only 5ghz i connect to my TP DecoM4 ( which is connected to my Nokia fibre router)
My othe devices( that only use 2.4 ghz bands ) i connect dirrectly to my Nokia fibre router, that has 2.4ghz band active ...and also the 5ghz ,
So fo me its a matter of to switch 2.4 ghz on and off in the Android TPlink app .
Hope this give you an very straightforward option ?
good luck

Hi...
I don't if you already solved you problem but, probably, if you have router which broadcast both band with the same SSID you have option, in router settings, called SMART CONNECT set to the "ON"...
I found a solution that worked for me, i am using a xiaomi router and a s21
Samsung S21 Ultra 5G not connecting to 5Ghz wifi channel
Hi folks . I have a Samsung s21 ultra 5g. I can connect to the 2.4ghz WiFi but more than often I can't seem to connect to the 5ghz wifi channels .I'll have my laptop right infront of me onnected to the 5ghz wifi channel , yet my phone won't be able to the same. My router is netgear nighthawk...

Dear All
I own an android phone running Android 8.1. I looked at everything inside WiFi Setting but I can't find an option to selection only 2.4GHz or 5GHz frequency. Compare to my 10 years old phone runing android 4.4.2 which has an option for 2.4GHz or 5GHz. Is there any App that help to get this option enable or any workaround? My workplace use Band Steering which 2.4GHz and 5GHz use that same SSID and my phone always connect to 2.4GHz. I have to turn wifi on/off a few time to connect to 5GHz.
What radio bandwidth actually can get used depends on both the phone's hardware and the Wi--Fi network provider.
You can run this app to see what is possible:
https://apkpure.com/wifi-band/com.igorlazunna.android.wifiband
I'm no doubt Both of my phone and WiFi AP support 5GHz(Dual Band).
AFAIK Android OS has some algorithm for choosing the best Wi-Fi connection. I don't know what it is. But I think it tends to prioritize faster Wi-Fi networks over stronger ones.
5GHz is always faster than 2.4GHz regardless of signal strength for my experience so I just want my phone connect to 5GHz unconditionally. With my old phone, when I set to 5GHz only, it won't connect to any 2.4GHz event if 5GHz is not available. That's my goal.
