The issue I'm having is that when I am running an AOSP based ROM on my Note 2 I am unable to connect to the 5 Ghz band signal on a dual band router. They show up as available networks and when you select one I am able to enter the password but I can't connect to the 5 Ghz network, no issues with the 2.4 Ghz band. On a Touchwiz based ROM I don't have this issue I can connect to either 5 Ghz or 2.4 Ghz. Maybe this is a known issue but I can't seem to find anything about. Any help would be much appreciated.

This is a strange issue that I have not seen before. I was starting to have issues with my phone connecting to the wifi at the house. I decided to flash a clean rom today and hopefully that would fix the issue. I did a clean install and now my phone will only connect to the 5G band and not the 2.4GHz wifi band. I would like to connect to the 2.4ghz band but I get a message saying authentication error. I removed the connection and connected using the wps push button but when i do this it only sees the 5G. Any ideas what is going on and how I can correct it?
Do you see the same issue on the stock build ??
You are running what rom ??
Try the rooted stock build as a test. ..and if no change. ..reset the router and set up the connection on the device again. ..g
Have you tried turning off the power saver?
I suspect your router as the culprit but you can try going into the advance menu.
Hit *#0011#* hit menu then wifi menu.
I think you may even be able to choose the band? I think you can choose auto or manually pick 2.4 or 5ghz. Either way see if shutting off the power saver helps.

That is strange usally its the other way around...I have my dual band set up similar to yours..I named the 2.4 actually 2.4 and 5.0 same password..sometimes ill have to hit scan to show the 5ghz band...sounds stuiped..but make sure you click show password and make sure your entering rhe correct one..it may be so simple you may entered wrong password...or try changing the channel on the 2.4 ghz in rhe router setring to a different channel..mybe be a conflict..change it to channel 11..and reboot the router. ..
I have tried it on a stock rooted rom as well as CleanRom 3. Does the same. I have not tried a CM based rom to see if it only does it with the TW based rom's. I have checked the router and I don't see anything there that should cause the problem. I have 4 other android phones, and android tablet, and 1 iphone in the household and none of the others are having this issue. I have also noticed that it doesn't always say authentication error. Sometimes it says out of range even though I can be standing right beside the router. I am stumped.

Did you ever solve this? I'm having similar problem with my Note 2. I have a strong wifi signal incoming to the phone, but the transmission signal is very weak (verified using dd-wrt on the router and looking at client signal strength). My Note 2 has extremely poor strength.. ~10% where every other device on my network is ~50%. I've tried factory reset, turning off wifi power save mode.. not sure what else to try.
I am having a similar problem for the past couple months. My Note2 (ATT) with custom ROM won't connect to a 2.4 GHz wifi. No problem connecting to 5GHz wifi.
I saw an answer to this for a Sony Experia that the problem is with 802.11 mode and to change a file option gDotMode from 3 to either 1 or 2, but I haven't found a file with that option in it yet.
Same problem here, no 2.4 authentication unless the phone is very close to 2.4GHz AP.

I have noticed that in some public networks i can connect with no trouble, (I guess now that they're 5.8GHz)
but not at home
Any solution? I am using a note 2 i317m with stock rom 4.3 from TELCEL mexico carrier
During a recent update, I noticed that I've never updated my modem on my GS3. So I went on over to this thread and grabbed I747UCUEMJB to install it.
After installing it, though, I can't connect to 802.11n at home on 2.4 GHz. I can connect to the 5 GHz antenna just fine, but not the 2.4 GHz one (It's a single, dual-network router/AP). At work, I can connect to 2.4 GHz just fine (I don't know what flavor of 802.11 they're using here).
What happens is, I'll tap the network I want to connect to, enter my key, and then it just says "Saved and secured" or whatever the message is when it has saved the network, but it isn't connected to it. If I tap on my 5 GHZ network, it connects just fine. But tap on my 2.4 and it never connects (and never gives me an error, either).
The reason I want to use the 2.4 GHz network is that, for whatever reason, I get better signal from it, especially in the basement of my house.
So, can I just flash a different modem? Maybe try the next-most-recent one (I747UCDMG2)? I ask because I thought I remembered seeing some thread talking about downgrading from I747UCUEMJB that warned that you could brick your device by doing that...
You can flash an older modem but not an older bootloader.
I just discovered this with a little research with people having similar wifi problems. Simply change your router settings to 2.4 ghz band instead of 5 ghz band. For some reason the G4 is having problems with 5 ghz bands.
Or if you cant do that, just connect your phone to the 2.4 ghz band of your wifi if your router is dual broadcasting.

I'm trying it, not sure if it'll work. I've had 2.4 and 5 networks saved, i've just deleted the 5 network, we'll see if it's better.
Adding this line to my build.prop seems to have fixed this issue for me. I'm still testing but my phone isn't having any issues on the 5Ghz AC band.
wifi.supplicant_scan_interval=180

Didn't work for me
not connecting to 5Ghz is NOT a fix at all..
i didn't tried the scan intervall, i'll test it.
but i can confirm that either the reception is low and that the phone love to loose the signal :/
It also sometimes says that it has bad internet conneciton, so it refuse to connect (didn't found the setting to disable this stupidity... I know that on stock android under wifi settings you can disable this behaviour)
Sometimes it is also refusing to connect to a wifi... it just say registering and stoped...
only way to force it : reboot the phone...
hope that a software update will fix these issues.

Didn't improve the situation
I have a dual-band access point. The 2.4 GHz band is very crowded in my area, but
I seem to have the only 5 GHz-capable AP around.
At different times my phone seems to connect using 5 GHz and at other times
using 2.4 GHz. How does it decide?
Is there a way to configure Wi-Fi to prefer 5 GHz over 2.4 GHz when 5 GHz is
available? I would like to see whether that improves Wi-Fi performance.

Naturally you can only choose between 2.4, 5 or automatic.
The way I have it setup is to assign my 5ghz network with a different name, eg xda5 instead of xda while at home.
There may be an app to do something like prefer 5ghz. I'll have a look soon.
It mainly depends on signal strength as to what it connects to.
2.4 is stronger at further distances than 5 so it will prob connect to 5ghz when you are closeish and 2.4 when further away.

Thanks for the pointers, looks interesting, will investigate further

On my bone-stock, OTA MMB29Q build, I can go to Settings>WiFi>(three dots)>Advanced>WiFi frequency band and choose Automatic, 5GHz or 2.4GHz.
(I, too, have given my 2.4GHz network a different name than my 5GHz network, but I don't know if it's really necessary.)

UnusualSuspect,
Thanks for the tip. But if I select 5 GHz in that setting then I won't be able to connect to 2.4 GHz when that's the only thing available
without changing the setting again (at least if I understand correctly.) This could do in a pinch, but I am looking for something "automatic."
Darke5tShad0w,
WiFi 5 seems to do what I want, at least after 5 minutes of testing
But the notifications don't work on Nexus 5X/Marshmallow 6.0.1.
So I'm also using WiFi Band just for the notifications, as the experimental
"prefer 5 GHz" feature doesn't seem to be working for me.
Thanks again!

I have noticed the problem that when searching for 5 ghz Wi-Fi networks my cell phone cannot find them, do you know how to solve it?
I have the latest version of miui 12.5 global version

Rmn8p don't support 802.11ac. Try to change your router to 802.11a or others.
