Note 2 N7100 wifi search foreverrr - Galaxy Note II Q&A, Help & Troubleshooting

Hi all,
My mom had a note 2 for a year plus, everything works fine until the wifi decided not to work..
Sometimes it doesnt turn on and once it turned on the phone just stays at searching wifi network while every devices at our home is working.
So then I tried to fix my mom note 2 by flashing CM 12 but still it doesn't fix the wifi, still hanging at searching wifi networks.
Any solutions?

[Q] WiFi and GPS stopped working

so i've been playing around with kernels the past couple weeks ive had the phone, and didn't really notice until a day or two ago that my wifi and gps never connect anymore.
When i turn wifi on, the icon comes to the notification bar but then never connects - going into wifi settings shows "obtaining ip address" but it never works.
thought it was a kernel issue so went back to the stock rooted kernel and a few others with no avail. today tried updating the modem and still nothing.
tried on home and office networks, all of which were working just fine a week or two ago, and now i cant connect to anything.
same for gps, i remember when i tried zedomax's very first kernel my gps stopped working but reverting back to stock worked fine.
ideas?

does ANYONE know whats going on or am i S.O.L. and have to just go back to sprint?
im having issues with wifi as well it turns on for about 20 seconds then turns itself off,this started happening post update,I hate this no more WIFI DIRECT!!!!!!!!!!!!!!!!!! Or even connecting to home wifi its stock-rooted,all I did was re-root after the update was sent to my phone

[Q] Sudden wifi problem

Hey guys
I've had my note 2 for almost a month now and the wifi was working fine till today. It connects to my modem but doesn't open anything.
I've tried resetting my phone and modem but it didn't work. I also disabled Wifi battery saver and it didn't work either. I can't think of anything else...
Oh and other devices such as my sister's 4S/notebook connect without issues.
Nevermind,fixed it.
The problem was that my phone was connecting to a different IP(I don't know how the hell that happened).
Set my IP/PW manually in my modem and it's working fine now

[Q] Galaxy Note 2 WIFI connected but randomly No internet

Hi all,
I recently got WIFI connections in home and my phone wifi is acting kind of crazy.
It connects without any problems but internet doesn't work. I have to turn OFF and ON the WIFI in the phone for couple of times to make it work.
I flashed and running stock 4.3 from the sammobile after the release.
I just want to know it's is just because of 4.3 bug or my router is causing the issue. It works fine with my office WIFI network.
I can use all other phones and computers in WIFI without problems.
Any advice will be appreciated.

[Q] Wifi issues

Hey guys,
So all of a sudden, my wifi is searching and not connecting in a campus setting. My Samsung Galaxy Note 10.1 2014 is still connected to the same wifi my Note 4 was. I have tried rebooting, removing battery, shutting off and on data and wifi, and airplane mode. Nothing reconnects it. Also tried forgetting all networks since there are 5 when searching for networks it finds and reconnecting to one, still no dice. It's been 4 hours, still can't reconnect. Any ideas?

Have you tried to forget the network and then ADD it with + Add Wi-Fi network? I actually had an issue playing with a Galaxy note 10.1 2012 edition, I turned my hotspot (sprint note 4) on and named it the same as our current network (was showing how open networks aren't always the network they say and anybody can create a Starbucks-Guest network.... I used starbucks-guest because I didn't want to put my schools on here). The tablet didn't see the network even after reboots, but when I added the network manually it connected right away. Also was this connecting to the same access points or different ones on the other side of campus?
Yep tried forgetting, re-adding the wifi spot and nothing.
I've been having wifi connection issues since day one of getting this phone.
Not sure if I have the same problem.
But at least once a day, it seems the phone can no longer make a connection to my wifi.
The only solution is to either just power off the phone and restart or do what Sprint asked me to do.
Sprint said to try and reset the network connection information by dialing ##72786#
The phone will power off and then restart do some background stuff and then power off again and restart.
Once that is done, all is fine.
I've never had this happen on any other of my Android devices. I even use a static IP with my phone setup.
And yes, I have tried just using the default of DHCP.
I had thought it was my router (Asus RT-AC68U) which transmits both 2.4ghz and 5ghz. I have both setup and I try to use 5ghz the most.
I did upgrade the router software because I was one version behind, but that did not fix anything.
Also, I had a Sprint femocell in my house (provided for free from Sprint) because I had bad signal issues years ago.. But because this phone uses LTE and now it seems the phone comes with built-in WiFi Calling. (Means instead of using the cellular network it will use my network and ISP to make Sprint calls, all voice and text messages come through normally, it's basically a built-in femocell).
I returned that, whoops still in the box, need to get that mailed out fast.
I'm not sure how widespread this issue is, but I suspect it's bigger that just the two of us here. And if I'm in the wrong thread, please let m know.
Thanks
Rob

Galaxy note 2 only connects to wifi hotspot

Hey guys,
My galaxy note 2 got a problem of wifi. Doesn't like other wifi problems (cannot turn on the wifi), my note 2 can turn on the wifi but it cannot connect to the normal wifi (from router or modem) except the wifi hotspot (which can connect normally). When I tap "Connect", the phone showed "connecting" and then back to "saved", the wifi signal bar also dropped to zero for a while then back to full signal. I've tried many solutions but those are not working.
If anyone know the solution, please help me. thank you,
Is the phone running the latest stock ROM?
