galaxy s5 SM-G900F cannot find 2.4Ghz wifi connection - Galaxy S 5 Q&A, Help & Troubleshooting

Do you guys know how to solve this problem. Can't even see my 2.4Ghz wireless network. Can only see 5Ghz wireless network. Any suggestion ?

Reboot your router
Change the 2.4GHz Wireless channel on the router
Clear caches from recovery on the phone - can other devices see the 2.4GHz network? -
Disable the 5GHz network and see if it can connect to 2.4GHz then...
Can your router push out both 2.4GHz and 5GHz simultaneously?
Disable Smart Network Switch on the phone in WiFi Settings

thanks for your reply.
Yeah, Other devices can see 2.4Ghz and 5Ghz. Yes. I'm using RT-N66U so both 2.4 and 5GHz are available.
If my router was problem other devices cannot connect so, is not my router.
Following are done.
-Rebooted s 5 many times.
-Did hard reset/wipe cache
-smart network is disabled. ( Don't even put SIM card yet)
Phone is not ROOTED.

Suggestions?

Factory reset the phone?

Yes Factory reset and Hard reset is done but nothing change

Go to someone elses house who has 2.4GHz WiFi and see if your S5 can connect, then you'll know if it is a fault with the phone, or your router

My router have only 2.4 GHz but not problem with other devices.
My neighbor have both 2.4 and 5 GHz when we try to connect it's only show 5GHz band. Not 2.4. btw i'm running Lollipop 5.0

[Q] Wifi N

Hi,
I have a UK Desire Z. The spec says the phone is capable of connecting to b/g/n wifi standards. However I am having trouble seeing my N network on the wireless list. Has anyone sucessfully connected thier phone to an N network?
Are you trying to connect to a 2.4hgz network or a 5ghz one?
It should work on the 2,4 but not on the 5 ghz
I have dual-band router and Desire Z does see/connect to 2.4GHz N network. It does not see 5GHz network. But my 5GHz is running in two channel 40MHz mode, didn't have time to check if switching to single channel would allow Z to connect.
Mine connects fine to my home Wi-Fi network, which is 'N' standard. Not sure what speed it is connecting at, or whether it's dropping back to B/G though.
Do you have MAC address security blocking set on your router, and if so have you told it about the phone's MAC address?

This verifies that answer, changing to single channel on 5GHz will not make a difference.
The wifi radio on the DZ is a 2.4GHz radio.

[Q] 802.11n Issues

Is anyone else having problems connecting to an 802.11n network? My 802.11n network will not show up under networks. I've got no problems connecting to my g network, but cannot connect to my n network.
I've tried disabling all security, 2.4ghz and 5ghz and resetting the router with no luck. Network is working fine on my laptop and desktop.
I've tried using wifi analyzer and still nothing.
Any suggestions?

I haven't tried it, but I believe it'll only work if the Wireless N Network is the 2.4GHz mode. The specs for the TPT say it is compatible with b/g/n, since a isn't supported the 5GHz spectrum cannot be supported.
If your router is simultaneous dual-band, meaning, it can transmit a 2.4GHz and a 5GHz network at the same time then you shouldn't have any issues. If the router is only dual-band and not simultaneous then you'll have to fall back on the 2.4GHz spectrum.
Hope this helps.
Oh, ok. The router was transmitting in 5ghz; changing it to 2.4 worked.Thanks

[Solved] No internet connection via WIFI

Hello everybody,
everytime i want to setup my N4 it doesn't show my WiFi network / or not the 2.4 Ghz variant only the 5Ghz. The 2,4 Ghz version sends the signal at WPA TKIP and i also switched it to WPA2 but nothing happens. Anyone else has problems with it or solutions?
Thanks in advance!
Got it just made an update of the router and resetted all passwords

Wifi only connecting at 54Mbps

Doesn't matter whether 2.4 or 5ghz. I have an AC2350 router and tried multiple encryption settings. Won't connect faster than 54Mbps. Any help would be appreciated. Thanks!
