Wifi stopped working?

Today my GN decided it doesn't like my Wifi router. Been working fine before.
Wifi analyser sees the router and it is listed as a secure network but when I click to connect, it does nothing. Re-entered password, forget network, and rebooted etc. Not my router as my Xoom is happy with it.
Running stock gsm 4.0.1.
EDIT: Don't know why this should have made a difference but it is working again. Turned off WPS and changed wifi channel from 12 to 11 (had tried 14 before). Maybe it doesn't like certain frequencies?

Galaxy Note 2 Wifi issue

This is pretty strange so I thought I'd check here with people.
I got my new Sprint Note 2 today. When I was at home it connected to my wifi network and worked fine. When I got to work I connected it to our wifi network and the internet won't work. If I turn off wifi internet comes back.
Here's the kicker, I have my old iPhone right next to it connected to the work wifi network and it is connected fine to the internet. This is definitely going through wifi as I no longer have a data plan on that phone.
I checked with our IT admin who said that there is no need to "accept" a device on our wifi network. He also rebooted the network for good measure. After both phones lost the network (from the reboot) and reconnected the same thing happened. No internet from my Note but internet works fine on the iPhone. Restarting my Note doesn't fix the problem.
Any ideas? Thanks.

I have the same problem. Need help too.

Is the wi-fi sleep mode on?

Very odd. I've had no such problem at home,work or university

My network admin created a second wifi network to connect to (I guess our router supported it) and when I connected to the new one I got internet.
If it helps others try and solve the issue he tried pinging the IP address that my phone was using and said that he could only send information but not get anything back.

Try changing your wifi channel config in the router.

Hi, I've got the International version N7100 and experiencing weird wifi problem. I have tried to reset my wifi router and use static IP but it doesn't solve the problem. Btw, the problem is whenever I connect my Note 2 to wifi it would lose connection after a while then messes my router and connection of my PC to router as well. Never had this issue until I brought the Note 2 home a week ago. I had to restart my router and turn off my wifi on Note 2 for everything else to work. My iPad, iPhone and PC are all doing fine when Note 2's wifi is off.

I used to have terrible problems with my Virgin Superhub which all went away when I changed the security settings to WEP hexidecimal from WPA2-PSK (AES). Laptops and phones would have intermittent connections all the time which a reboot or channel change would sort out but only temporarily. Give it a whirl.

I've been experiencing the same problem. It's especially annoying when I try to download big size apps on Google Play ( > 1 gb) because it will stop any moment and i will have to re-download it over and over again. It never happens when I connect to school wifi but it just happens when I connect to my wifi at home. Weird. Nothing is wrong with my wifi at all because my other computer is always connected 24/7 without any problem.

I have a similar problem on Omega Ron v5.0 with latest Andrei kernel. The phone gets stuck sometimes in getting IP address part or have disconnects. It's annoying.

Afraid not.
I did that after other efforts failed but still have to go through same issue every now and then. This is not a permanent problem but something that occurs at least once a day for me.

Also having Wifi issues with GN2 from Sprint
I got the GN2 on it's release date (this past Thursday) through Sprint. Got it home got set up, connected...everything worked beautifully.
After a couple of hours, downloading apps etc. I noticed it had stalled. Turned off WiFI and used the network to finish. Turned back on WiFi and Voila, action again, but a few hours later it stalled.
I first made sure all of my settings were in agreement. No sleep mode or anything like that was enabled. No power saver either.
Couple hours goes by, WiFi connectivity stalls (even though it shows a full signal) I contacted TWC and made sure it wasn't the modem/router. I changed the wifi channel, tinked with the bandwidth... everything worked...an hour later it stalled. Called Sprint they said I had a dud, took it back, exchanged it, got the new one... SAME ISSUES. YEsterday I connected to my Church network HOPING it was an issue at home, but not so. After an hour on the network it stalled.
Contacted Samsung today and they have had no complaints according to them so i said I'm happy to be the first... If anyone finds a fix please let me know.
PD

Do you have any solution yet? I have the same issues with 2 different networks. I already contacted Samsung, but they only say I should do a reset of my device and read the setup instuctions for wifi. I'm still in contact with Samsung and hardly try to get a solution.
Stay tuned, I'll post any news I can get.

I'd prefer it to work with the stronger encryption of WPA2 rather than WEP.

OP: it will be great if you could add a poll to the thread as that way we can see whats the percentage of users are experiencing this issue,
Thanks

I had this issue with my S3, but never with the Note 2. What i did in that instance was reinstall the OS and that seemed to have fixed the issue. Hope this helps!

Same issue here. Connect wifi and I'm able to hold connection for as little as minutes at times. Turn back on 4G and I'm fine. If I re enable wifi straight after it works intermittently. This is true of both my home and office wifi. So I'm lead to believe it's the phone.

Hi,
Almost the same thing here. everytime I go out of my home and comeback the wifi network seems to work but no internet access. I have to stop and restart wifi then it works.
very strange issue. ok I have a work around but I'm going to open a ticket to Samsung.

Same issue - connects for about 30 seconds
I've tried on different routers. Other devices (iphone, ipad, S3, etc.) all work fine. Sees the wifi network. connects, then disconnects and TURNS OFF WIFI. I can't figure out how to go to service mode to see if this is a timer issue. I've tried on both G and N networks. using a verizon fios, actionteck router (and netgear). Also, will not remember the password credentials. tried router reboot and fidling, etc. Driving me nuts. any suggestions ???

[Q] Poor wifi signal

Sooo I've had my M8 for nearly a month now and I love the thing. However, I notice that I've been having some issues with the M8 not being able to detect or connect to my home and office's wifi. My laptop and my fiance's Nexus 5 can detect our home wifi network with full strength.
Interestingly, the closer I get to my router, the stronger the signal gets, but the moment I move maybe 20 feet away into another room, the wifi cuts out or gets very weak. I understand that distance is a factor, but I feel that my M8 should be able to connect to my router in the next room, especially when other devices can do so with no problem.
I think it's also worth noting that this was not always an issue. This only started happening recently - the only software upgrade that I did was the Verizon push that installed right out the box. I have not made any changes to my wifi network at home or work.
I've tried a couple of things with no resolution, including;
Resetting my router (power cycling)
Restarting my phone
Forgetting both wifi networks and manually re-adding them
Changing my wifi direct name
Turning on airplane mode, turning off my wifi, turning off airplane mode then turning on wifi (this was a suggested method for the M7 that I saw on another forum)
I did some Googling and didnt find much, so maybe I just have a lemon, but I did see that wifi connectivity was an issue with the M7.
Any ideas or suggestions would be greatly appreciated!

I'm having the exact same problem getting over 20Mbps over Ethernet but then 0.25Mbps on my M8 over WiFi even when close to router

Have you guys played around with your routers settings?
What signal is your router on, wireless b,g,n,ac?
Is it throwing mixed frequency? (2.4ghz or 5ghz or both)
Go to WiFi settings in the phone, then advanced, then it will probably say "auto".
Try setting it on only 2.4ghz or only 5ghz see if that helps.

LG g3 WiFi issues

Is anyone else having this problem? My phone keeps dropping the WiFi signal even if I'm next to the WiFi router. The WiFi indicater shows good signal with all bars lit at all times and I don't get any notifications of signal being low but it still doesn't load/connect to anything. It's very sporadic, but regular.. once singal is lost it won't load anything for a minute or 2 even if the WiFi on the phone is turned off and on. I've tried resetting the router but the problem still persists. All other devices connected to the same WiFi don't have any problems. I'm using the virgin super hub by netgear.

Same over here. I have 3 other devices on the same router and none have a problem. Restarting the router does not solve the problem.

I have a similar issue at my partner's house. When I first got the phone I had no issues connecting to the 5 Ghz wi-fi connection, but lately I have issues with the 5Ghz, but connecting to his 2.4 Ghz connection works well. His device and other household devices work well on the 5 Ghz connection. It is annoying, but since the 2.4 Ghz seems quick, I am not going to worry too much about it right now. Hope there is a solution though.

I remember my z1 having similar problems...it was fixed by changing the security mode I think...wep..wpk...or something...just fool around with it...no harm in trying

I have a NetGear accesspoint that the G3 refuses to connect to regardless of the G or A bands. So frustrating.

Stard having this issue this weekend, thought it was the router location and I repositioned and still no help.
Hoping and update fixes it

I too have experienced issues with WiFi during my last 4 days of ownership. Perfect WiFi signal (I was sitting within feet of the router) yet no Internet connection. Cycling WiFi off and on fixed the issue. This occurred on two different networks using different hardware. Both were using WPA2-PSK authentication. No other devices on the network experienced any issues.

Go to WiFi ans hit the top right button and go to advanced setting than put yes on keep WiFi on when screen is off

That option was already enabled on my device. I never enabled it, so it must have been on by default.
Also, when this happened, my G3 still had a valid IP address

Have same problem since day 1. Cycling between 5Ghz and 2.4Ghz and vice versa seems to fix for the short term.
But seems to happen on a daily basis.....!

I have the issue has well. In fact, mine will sit at obtaining IP address.

i have same isuee
i have same isuue here with my lg g3 16 gigs model
wifi sigal drops all the time i did factory seetings and did not help
plzzzz help as am start to hate my device

add static ip address to resolve the issue
I added static ip address and it was able to connect to the wifi but it will
be the same problem when you connect to another wifi at a different location.
Do not change network prefix length/DNS1/DNS2. Keep these the same.
You could use this as temporary fix at home atleast and connect to wifi.

Disconnect completely from your WiFi, switch off WiFi on the phone, turn back on and go to advanced settings, uncheck the Google auto scan thing, then connect back to your WiFi.

Still have same problem

It worked on mine. Much more stable.

I am also experiencing this and it is really annoying. Toggling WiFi off and back on always fixes it, but that is not an actual solution because the problem happens so frequently.
I have tried:
Disabling Sprint connection optimizer
'Keep WiFi on when screen is off' is enabled
'Allow WiFi scanning' is disabled
'WiFi signal weak' is disabled (set so that it does not disconnect from WiFi when signal is weak)
'Battery saving for WiFi' is disabled
Using a static IP address
Factory Reset
Forget network
I still have had no luck. Does anybody else have any suggestions? I have about a dozen devices on my network and they play nicely; this is the only device giving me trouble. I am starting to wonder if it is time to RMA?
EDIT: It doesn't seem to happen when I connect to the WiFi at my work. Hopefully flashing a newer build of DD-WRT will remedy this. I love this phone except for that one issue; unfortunately though, this issue would be pretty hard to live with....

Same thing here. Before G3 I had G2 and Flex, both had the same wifi problem. Funny thing is that some $150 Chinese almost noname generic phones never have this problem on my home wifi. It's exclusive to LG.

Same Problem here. I am having a Nexus 5 sitting next to it. No problem with the N5 but constantly interruptions with the G3. This phone is starting to annoy the hell out of me.

I have the VZW G3 rooted, have no issues with WiFi on either antenna using an Asus dual band router.
I did have issues with a dlink, but it had issues with all phones not just the g3 so I replaced it.

So it's not just me. Hmm.

Yes i think its aome software problem because it worked for me first time only for a 10 mins and then it never connected.
I even tried hard reset but not successfull.

So I tried connecting to it again, and I noticed it keeps losing sight of the wifi connection. It will show my 5GHz network out of range, and then try to connect, then show it out of range for a bit again.

I found a solution go to wifi settings and go to menu and advanced and turn off smart network switch and always allow scanning. And then reset ur modem and router and it should work .
It worked for me and now my 5ghz is working fine.

Mine has worked since I got the phone. With the authentication error, are you positive you've entered the correct key? With the weak signal, have you tried a different channel, maybe some interference going on???

Yup I'm sure, it's the same password as the 2.4GHz network. Besides that, it works for my laptop and tablet perfectly fine.

I reset my modem and router again and now it worked. Guess it just took some motivation lol.
On 2.4GHz I got like 15-25mbps on my wifi.
Here's 5GHz:
Wish Verizon's LTE wasn't pathetic compared to the competition, especially given how expensive they are.
