Hi XDA,
My Netgear router has Dual-band support 2.4GHz & 5GHz...
I don't have problem in 2.4GHz, if the N7100 is in standby mode or in restart it will get connect automatically when the system resumed...
In 5GHz mode it is connecting and speed is twice faster than 2.4GHz,But the problem is it is not connecting automatically when the system resumed from (standby or restarts)... i have checked all the WiFi policies in N7100 but no use.. am getting same Issue when i tried with different 5GHz routers....:crying:
am also am using iPhone5 its working fine in 5GHz mode...
Think XDA will solve my issue soon:angel:
Thanks in advance..
Plz share your experiences
Can any one help?
My N7100 is not connecting automatically to 5GHz WiFi router
i have similar issue with a tp-link tl-wdr4300 router, so it must be some phone limitation. i would also like a solution to that if it's possible.

yes AFAIK the phone doesn't support the 5GHz wifi so its hardware limitation as they said,
hope I answered your question,
Bests

I have the same problem and 3 firmwares have gone by and still the problem exists. Connecting to the 5ghz manually works but turning from off to on, the n7100 does not auto connect to the saved 5ghz wifi. I am using an Apple Airport Extreme at 5ghz-only mode.
Published spec includes 5GHz:
WiFi 802.11 a/b/g/n (2.4 & 5 GHz), Wi-Fi HT40
I have netgear dual band too, but I cant test this because I set all the radios in my netgear plus my powerline extender to the same SSID so the phone can roam between them transparently.
5Ghz has a too short range for me unless I sit in the same room.
Is this related to the "wifi bug" that so many users report, in several threads?
You know, when wifi speed decreases to ridiculous levels, as soon as phone
goes into "sleep mode" (AKA as soon as the screen goes black). In that case
welcome to the club. I've been waiting for a fix since end of January, when we
all were "blessed" with the 4.1.2 fw. I don't think Sammy gives a s**t anymore.
With a revenue of about $8.3 million, I guess they don't care to give a f**k....
If the wifi problems aren't solved with the 4.2.2, this is my last Sammy.
The Note 2 definitely supports 5ghz 11n, but range is quite limited, due to the nature of 5ghz. I've found it only picks up channels < 48, regardless of which region it's set to. Setting a static IP speeds up resume from sleep at times.
I was facing same problem as u mention,repeatedly i gave for repair to authorised service centre & finally they replaced a board,now wifi is works like charm.

Thanx alot! That was news to all of us, I think!
It's strange though, that the problem on my phone
only appeared AFTER the 4.1.2 fw was installed.
Perhaps I should just pass it over to the service
guys, instead of waiting another month(s)....
Anyway, mucho obligado for the info!
Of course it was not easy,I was keep flashing different country stock rom in hop may now they fix the issue,when given first & second time to service centre,they kept my mobile for 3 to 4 days & return me saying no problem found,I am regular reader of XDA so aware of SDS also, I was feeling like cheated by samsung,carrying sick mobile all the time since I have Insane cheap also,but finally they replaced motherboard with sane cheap & one more board for Wifi issue.
Is this issue not the same like the roaming bug? My N 7105 has got both.
I solved it on n7105 with the latest firmware. It now roams smoothly on wifi and it prefers 5 ghz close to the router, at -40 db.
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.

Do your 5ghz and 2.4ghz have the same name?
Does it pick up your 2.4ghz when you set your phone 2.4ghz only mode.
What rom and update are you in?
1. No
2. No
3. Latest stock
... Nvm now that i used another house wifi and back again to my home it got fixed. I really dont understand what is going on
It maybe rom specific problem
Hi all, I can only connect to 2ghz wifi, 5ghz wifi does not appear at wifi settings. I remember when unbox the phone I connected to 5ghz wifi, but now no. I'm dreaming or anything goes wrong?
Edit: done a reset in recovery mode and 5ghz wifi appear in settings. I will not restore a previous backup
Edit2: I finally found what happens, if you untick the 5g in SIM settings the 5ghz wifi band stops working. And if I active the VolteHD I can't identify the contact.
Edit3: No working 5ghz wifi after 10 minutos standby.
Best regards.
Ill tried this but didn't work more than 10 min.
Any idea why this happens?

Yesterday, I did a safe reboot to the phone and I got some hours of 5GHz band connection without issues.
Today, I turned on the WiFi on the phone (I sleep without it activated), and connected automatically to the 5GHz band.
But after 30 minutes has passed, the problem showed again (no 5GHz band, no 5GHz neighborhood bands).
My old phone still reach them and can connect to the 5GHz networks.
Really annoying bug. Also, it seems it's nothing related to the 5g button / mobile network settings
I'm connected to 5ghz just fine, however personal hotspot only works on 2.5ghz.

you are the only man in the world! check in properties of the wifi the speed and you will see that is connected to 2.4ghz. Only one question more, do your wifi have two ssid, XXXX and XXXX5g? or the ssid is the same for the two bands?

I have two ssid, and i have two passwords for each ssid. In my home only works WiFi 5ghz and i have the mobile data off. If i'm the One i don't no, but is true for me the WiFi network os perfect for now.
Guys I'm on North America version 3.08 and I have no 5ghz Wi-Fi issues at home. I have 5G enabled and my VoLTE / caller ID is working perfectly on T-Mobile as well. My Wi-Fi has two ssid, XXXX and XXXX5g with the same password.

Enabling 5g removes the volte option so you can't have both

I realize that but I was just saying that my data is working perfectly on 5ghz Wi-Fi and T-Mobile.
Global 8GB/128. No issues with 5ghz bands.

I have the same problem with 5ghz wifi. It happened randomly from time to time in not able to find and 5ghz ssid. The only way to make it work again is to restart the phone and my phone will be able to see and connect 5ghz wifi.
I also have no problem with 5Ghz WiFi issues. Mine is NA/Asia version 3.13 8/128 variant.
Similar issue 5ghz hotspot
I did not have problem connecting to 5gh wifi, but i had another issue where my other devices supporting 5ghz band could not detect my 5ghz RM5G hotspot. I found a solution in this website for another problem but it solved this issue. Just switch the sim from slot 1 to slot 2 and restart the phone. This fixed the problem for me and all my devices detected and connected to the RM 5ghz hotspot without problems. Maybe this would work to make the RM detect the 5ghz wifi.
