Wifi problems - Galaxy Note II Q&A, Help & Troubleshooting

Hello,
Often the wifi does not work. the telephone connects to the network but does not transfer data
The wifi signal is always present. Very often fails to communicate with the router does not transfer data in and out
The same problem was present in the previous version of the Phoenix Rom
I think the problem is not the Phoenix Rom
I reinstalled the bootloader MJ5, but the problems continue.
I'm afraid it's a hardware problem
Should I change my phone?

This problem has appeared 1 month ago. I've also updated the ROM, but the problem persists.
The wifi symbol is present. If I try to browse, or other applications that need internet connection, do not work.
It does not happen always, but often
The problem occurs in various ways
For example, while I'm browsing
Or while I'm using Facebook
Or for example if it is in standby, I realize that I do not get notifications or email
Maybe the problem is hardware?

Maybe I'm wrong, but now it seems that the problem occurs only with the wifi connection at home.
But at home I changed 2 modems in the last 10 days
The wifi connection of the PC always works well with both modems

[Q] Wifi doesn't work

Hi there,
Today I recognized that my wifi doesn't work. I can switch it on an there is also a massage that there is a wifi network available in the notification center. But if i open settings/wifi the phone writes no wifi networkes available.
My Z1c is rooted (KK .757) and locked bootloader.
Has anybody a idea how I can solve this problem?

This happens to me sometimes, after a restart works for me. May be next update may solve this problem
I've already restarted 3 times but doesn't help.
You can try: 1. restart your router
and 2. delete the settings for your network in your Z1C and make a new registration.
Is the problem solved?
I think no.1 will solve the problem. What a router do you? Many routers can do a automatic restart after flashing DD-WRT or Open WRT. These firmwares are available for the most routers.
greetings
What do you mean with 2.??
I've already tried to restart my router. But I'm pretty sure that the problem isn't the router because I can connect with other devices to the router.
go to settings - WLan and tap long time on your network and delete it.
It does not matter, that other devices can connect to your router.
I had the same problem with a TP-Link router after few days running. A restart helps only.
Delete the network doesn't help too.

For sure you have problem with your router since low cost routers is nothing than an s***t ! I had the same trouble with an low cost router until I come back with an good Dlink DSL2740B router 5 years ago, everything working flawlesly constantly ~5 years, no wifi isues! My sugestion to you is to buy an good home router! I have plan to bye this one http://www.dlink.com/us/en/home-solutions/connect/routers/dir-880l-ac1900-wifi-router which will work for sure perfectly next 5 years (probably more)!
I've solved the problem already. The problem wasn't the router.
I had to wipe DATA and then my WIFI worked again.
Then I tried to restore a backup what I've made befor but then wifi doesn't work any more.
So there was something buggy with my DATA..

Cannot connect to WiFi

Is anyone else having issues connecting to wifi? When I try to connect to wifi at my house, I get a pop-up error saying "AP currently not in use. Internet connection slow." If I click retry, it comes up again. If I click cancel, it says "Failed to obtain IP" and is not connected.
I have tried restarting my model/router with no luck. My Note 3, laptop, and other devices have no problem connecting to this wifi network...
I had a problem with wifi,but sounds different then your issue.Mine would just disable after obtaining ip.Samsung rep at best buy reflashed phone.That saved all data and apps.AND,it fixed wifi.If you can't work thru your issue,go to best buy or att store and get it reflashed.Cant hurt.
Good luck.
Sent from my SAMSUNG-SM-N910A using XDA Free mobile app
OK, so went to the ATT store today and they reflashed my phone. Got home just now and tried to connect to wifi, same issue
Is anyone else having this problem?
Fixed it.
SOLUTION: I changed my router encryption type from WEP to WPA and now it works no problem
Try rebooting your router, I had the same issue the first day I got mine and a reboot fixed it.

Your neighbors are going to be pissed. They can't steal your wireless any more.
Seriously... You did yourself a favor... WEP = ROFL stupidity for wireless networks.

No go for me I just Got my N4 from Verizon last monday and having the same issue u had. I changed my encryption from wep to wap and still same problem. Ima go to a verizon store and see if the "reflash" the phone like some suggest here. Might help my problem
Hi all,
I also experience the same issue from time to time. I have this happen on both my home network (WPA2-Personal) and work (WPA2-Enterprise). My fix is to either reboot the phone or activate Airplane Mode for about 20 seconds and then disable Airplane Mode. After doing that, wifi picks right up for me. YMMV.
I can try to get the exact error log messages from our networking technician at work if it would be helpful to anyone.
Out of curiosity, do any of you have other peripherals connected at the time you experience the issue (Pebble Watch, etc.)?
Same issue
With my GN4, I can connect to my home WIFI no problem and my GF's WIFI no problem but when I go to my Dad's, I CANNOT connect to his WIFI (Netgear WTG624v3) but both of my sisters with a Samsung Tab 3 and Samsung S4 CAN connect to my Dad's WIFI. It's really aggravating. Basically, when I try to connect, it says "connecting" "saved" Then it says "scanning", and says "connecting" "saved" again and again ..... But never connects.
I have tried changing just about every WIFI setting on his router including resetting the router. Tried removing the encryption making an "Open" network and STILL can't connect... and tried every encryption type provided and still nothing. I set the dynamic address range from .4 to .254 (on router) so I could try connecting with a static address to 192.168.1.2 / .3 and still nothing. I tried removing my GN4 browser cache, and setting it to airplane mode(20 secs)... nothing.
I'm at a loss.. given that both of my sisters with two different devices can connect to my Dad's WIFI but I can't with my GN4? But I can connect my GN4 to other WIFI networks, no prob.
UPDATE: Next, I will try downgrading the firmware version on the router to an earlier version. Hopefully, that's the solution. I will report my findings here.
Downgrading or using an older Firmware version for this Netgear WTG624v3 router DID THE TRICK!
If anyone else is having the inability to log into a WIFI router, try installing an older router Firmware version. I got the idea from here:

WiFi is unable to find any network

My Nexus 5x seems to be having problems with the WiFi. I have Android 6.0.1 MMB29V, and everything was working fine until I couldn't connect to my network. When I checked the WiFi settings, it seems that there isn't any network at all. I've seen in this forum that there have been some problems with the Wifi but I haven't found any solution to what's happening to me, cause it has been a few days and it still can't find any network.
How can I check if it's the antenna what is broken? I have no idea what can be happening...
Note: I've tried changing the frequency band, the "Keep WiFi on during sleep", the developer options of using the DHCP from Lolipop and some others...

Has it ever connected to your network or has it just started happening.
Have you tried turning your modem/router off for a few minutes then deleting and readding your network?

I used to be able to connect to three network I use, but now I can't even see the network. I don't think it's because of the router, cause with the PC I can see a lot of networks, none in my Nexus.
I may try to unlock bootloader and update to MHC19J and see if the problem is solved

I had an issue where I needed to reboot it even though everything else worked fine.

Nexus 5X can't find any wifi network

So I bought a Nexus 5X 2 days ago. When I first started the phone it was running Android 6.0.0 and it didn't have issues. But a update for 6.0.1 showed up and I downloaded it. And then the issues came. It cannot find any wifi network... The problem isn't from my network, because every other device finds my home network and all the neighbors network, but the 5X doesn't find any... I tried factory reset, network reset, cache reset, nothing helped. I even tried Android N beta and for a moment it fixed the issue, but this morning the wifi problem occurred again. I sign out from the N beta and through Mobile network it managed to download the last stable version(that's what google is calling it) - 6.0.1 and the problem was still there.. after some restarts of the phone and some factory resets, i thought the problem was gone, because it managed to find every wifi network in the area, but after i used the phone for 25-30 minutes, the wifi problem occurred again and ever since... So, is this a common issue with the phone, or the android 6.0.1, or is my phone a defected one? Should I go to the store and ask for a replacement? Or will the next phone do the same thing ?

Hi something similar happened to my 5X (6.0.1). It was able to find wifi network but I was not able to use internet even-though internet was working for other devices. I have restarted phone but my phone stuck in to WIFI Obtaining IP address...
I have restarted my router and problem resolved. Happened two times. Might be some bug in software.
I'm currently facing this very same issue, no WIFI networks are showing up. I've already flashed latest N preview with same results, funny thing is that this morning was working just fine. But I had to reboot the phone and now it won't detect any WIFI Network at all.
I'm starting to think I have a failed unit, but since I'm outside the "US" I can't send it back for warranty repair. So I'll just keep it and keep restarting until it's fixed again. This is really frustrating, never happened to me with any device I owned before.

Is it every wifi or just your wifi?
If it is just your wifi, try factory resetting your router after recording the settings, or try removing some entries that my be using NVRAM.
I've seen cases where the router runs out of NVRAM to record the DHCP entries and that causes connection issues. It doesn't show up for other devicdes because their entries are already stored in NVRAM. It is just the incremental new device you add that triggers the problem, so you naturally think the problem is with the new device since all your other devices work with the router.
my solution for wifi not found/working
i´ve upgraded from the nexus 5 to 5x.
i had a really weird issue with my wifi.
only found my wifi when i was not in airplanemode. so i read 1000 of articles about the wifi of the n5x.
just the standard blabla. so i did my own research
while my n5 and my n7 + 2 laptops had never issues my new 5x didnt find my wifi. i really thought it was an hw-issue. but it wasnt.
i am using a fritzbox router. newest update, made a reboot, rebooted phone. nothing happened.
then i checked my wifi channels, set it to manually and instantly found my wifi. i really never expected that the channel got such a big influence. may be the latest update brought a bug for the wifi channels or the hw is just not capable of some channels, dunno. but this is what helped me and it was nowhere mentioned in any forum.
tl;dr
try to change your wifi channel of the router.
edit: btw i found the 5ghz while the 2,4ghz wifi didnt work. but i wanted the 2,4ghz wifi to work because of the short range of my 5ghz wifi.
atm i am on channel 8 and i got no problems with the 2,4ghz wifi network

I don't know about Europe, but usually in the US we only use channels 1,6,11 to prevent overlap.
This is because there is overlap in the channels so you can't really use the in between channels due to too much interference. If you are the only wifi transmission in your area it is fine to use any channel, but if there are others and they are using standard channels for no overlap/interference and you are using in-between channels, your signals are probably going to interfere with each other.
When everyone is using the set channels, then they can negotiate properly and everything works better. With overlapping frequency bands, the negotiation doesn't work well because your signal sometimes looks like noise to the other device.

Hi, thanks for your help but unfortunately it's every wifi... it just hangs on "Searching for Wi-Fi Network..." and stays there...
I already talked with LG and they asked me to send the unit for repair, but I'm no in the US anymore (I was for a short time of period and that's when I bought this phone). So that would not be an option, right now I'm only using 4G and trying to measure it, lol
Just another question, do you guys think I could use a WIFI external dongle through USB OTG? Could that be possible on the Nexus 5X?
Thanks for your help! :good::good:

Hi, thanks for the suggestion but the problem I'm facing it's with every wifi network around, not only mine.
I guess unit is defective, but could a simple reboot trigger this kind of behavior? This is strange, never happened on any device I've owned before. :crying:

I had exactly the same issue and found out that my main router was at fault. If you have a spare wifi router laying around try set it up as access point and connect to that instead. Or go to a public wifi place or a friends house and see if its the same.
For me it only happens if I use our main wifi router at home even know my pc and other devices have no issues. Very weird but I can almost guarantee that your phone is fine if its the same issue :fingers-crossed:
My phone worked fine the first month with my main wifi router but then it started happening out of nowhere. I unlocked the bootloader and installed a custom rom and same thing was still happening. Then I found an old wifi router that I plugged into the main router as access point and now I haven't had any disconnects for almost a whole month.
