D855 running 21A cannot see 5Ghz WIFI hotspot - G3 Q&A, Help & Troubleshooting

So I just restored my phone to stock (21A KDZ) using the flashtool. I have no problems connecting to the 2.4Ghz WIFI hotspot but it cannot see the 5Ghz one.
steps I've tried:
1. turning WIFI on/off
2. I've restored it to stock via flashtool twice
3. performed factory reset via stock recovery.
My Macbook and 6s+ are both connected to the net using the 5Ghz hotspot so that's not the issue. When the phone was running cm12.1, it was connected to the 5Ghz hotspot too.
Any ideas what could be wrong?
Thanks

bump!

I came from cloudy 2.5 It saw the lower (36-48) channels only.
Have you tried Marshmellow 30b? My phone can now not only see the lower channels @ 5ghz, but it can also now see the higher channels (149-165) although there is a bug where if you enable wifi hotspot and turn it off, it will only see the lower channels until you reboot the phone.

[Q] WIFI connects but no internet?

Today I updated my ROM from LeeDroid v2.5 to v3.0.8.2. I wiped my phone first. After this I rebooted, then rebooted again into recovery and installed the recommended radio (32.56.00.32U_5.17.05.08). Then I restored my apps+dat with Titanium back up and rebooted again.
It soon became apparent that whilst mobile internet was working fine, WIFI wasn't. While my phone will connect to the router it won't connect to the internet. If I enter the local IP of my router I can browse the settings fine. I tried "forgetting" the network and re-entering security code but this still didn't work.
I restored my v2.5 nandroid backup and the internet worked fine, the radio is still 32.56.00.32U_5.17.05.08.
So I did a fresh install of the v3.0.8.2 ROM and tried connecting to WIFI again and again the same problem.
So my question is, is this an inherent problem with the ROM, and if so why does no one else seem to have this problem, or is it a setting issue?
Any help would be much appreciated.
Also I tried changing the WIFI channel as suggested in another WIFI thread, and this didn't change anything. Except the WIFI channel obviously.
And I tried a static IP address and that didn't work either.

You try turning off router and putting back on again? I sometime's get that in my network.
Yes I tried turning my router off for a couple of minutes then switching it back on. Didn't change anything.

Did you sort it?
I think you need to wait before the router give your router assign an ip for your phone, btw, some router donot fit all phone model
Yes thanks I managed to sort it today by following this thread
Apparently the fault is inherent to Android 2.3.3 and seems to present itself mainly with Thompson routers. It was a static IP I needed, I'd not entered the details properly the first time.
Thanks for the replies!

[Q] T-325 NK1 firmware Wifi problem

Hi
I installed the new NK1 firmware on my t-325 and since then my inernet connection keeps dropping with "AP currently not in use. Internet connection too slow" message. The internet connection is obviously not slow and signal strength is maxed out. Is there anything I can do ? I have already regretted upgrading. :crying:

I have the sm-t320 also on the NK1 firmware but I haven't experienced any wifi dropouts , but I did a clean install by doing a factory reset, have you tried to remove the AP and re-add it back in?
To remove the network go to Settings - Wi-Fi - Long Press on the AP and press "Forget network" , then refresh networks and re-connect to it, or if SSID is hidden scroll down and click Add Wi-Fi netwrok.

Yes, I tried everything but to no avail. I even selected another channel on the router. My wife has the same tablet with the older firmware and everything is fine by her.
It seems that I need to roll back to the previous firmware but I don't know how to start it since I have never had a Samsung before. I downloaded the original firmware, Odin v3.9 and installed Kies to have the necessary drivers. I don't want to brick my device, so is there anything I need to be aware of before I start flashing ?

WIFI not working after flashing custom rom

So far I have tried:
ace2nutzer: cm-11-20150714-UNOFFICIAL-codina.zip
ChronoMonochrome: cm-11-20150730-UNOFFICIAL-codina-universal.zip
MIUI6_5.7.26_I8160.zip
vanir_codina_4.4.4.092615.zip
CyanogenMod12.1_I8160_0920.zip
The wifi is not working. I was not able to connect to my D-Link 868L router. I notice that the mac address of the wifi adapter is now 00:00:00:00. Btw, to check that my phone's wifi was still working, I flashed back the stock rom and it could work.
How can I resolve this? Would appreciate some help.

Missing 5GHZ wifi networks on multiple ROMs but not on stock.

I got another G3 due to the SIM card issues on my original phone. The phone was upgraded to 30E and then downgraded to 30D, Kingrooted, TWRP installed and then tested with following ROMs.
Fulmics 7.5
XenonHD
CRDroid
Each of these ROMs would not detect any 5GHz networks, even using WiFi Analyzer shows nothing. 2.4GHz works fine.
I then restored the stock ROM and the 5GHz networks would show and connect without any issues.
Anyone have an idea where to look or what could be wrong?

Found the issue on CRDroid, havent tested the others. Looks like you need to set region for 5GHZ
WiFi > advanced > WiFi frequency band.
