WiFi issues?

Not sure if it's just me, but WiFi will randomly disconnect every 5-10 minutes for a few seconds, then reconnect itself. My m8, nexus 5 and nexus 7 2013 are not suffering the same so I'm assuming it's not my router. Anyone have any thoughts?

I think the range is weak in my house my 5ghz on my s5 was 585mbps and my g3 is 296mbps but wifi works great but in my job We have like 5 differend ssids and they all disconnect alot and they all different routers but I guess in my house being closer doesnt log off but at work it does

guys chill! you dont have any problem with your wifi. our phone is looking for a better signal, if it doesnt detected that you have a poor connection it will disconnect itself and it will toggle on your cellular network.
here is your solution
go to your wifi click settings > advance wifi > and uncheck Wi-Fi signal weak and bam. you have your wifi connected all the time!
hit thanks will ya?

Lol same problem s5 wifi signal os stronger on same ssids

I also have this problem and I decided to debug it.
With my jabber client which logs every disconnect I found out that it disconnects from wifi every 5 minutes.
So I opened my router settings and found that only setting that is set to 5 minutes is interval of "Group Key Update". So I changed it to 15 minutes and now it disconnects every 15 minutes.
So it's not solution, but only a workaround. So i will set it to few hours and hope that LG will fix it soon.

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.

Intermittent WiFi disconnects

Has anyone been having any issues with the WiFi randomly cutting out?
Sent from my SHIELD Tablet using XDA Free mobile app

Mine did it twice today, whereas my G2 would know to reconnect upon scan...
Hopefully this is just a one. time thing.

Hopefully your issue isn't as serious as mine is. I literally just got off the phone with T-Mobile and they will be sending me a replacement phone.

I had this issue with my first G4, but i sent that back due to damaged leather back i have had a couple times with the second one where the wifi acts funky, not a problem but def like wtf moments

No problem with disconnects here.

Mine definitely disconnects and reconnects randomly

My verizon g4 disconnects periodically. Should I be ordering a replacement?

I haven't seen this with my H811 G4.

Only had the phone a day so haven't seen this yet but i did get it randomly with my G3. I could never figure it out. A quick on/off of the Wi-Fi fixed it quickly. Router is Netgear Nighthawk. About 8 other Wi-Fi devices in the house and never seen it on anything else.

I've been seeing this on my H811. It's nothing major but it does cut off then quickly reconnect after several seconds.

Mine also does this on the T-Mobile version.

H810 here. My G4 seems to strongly - and I mean really strongly - favor mobile data. My house is festooned with wifi access points and yet my G4 often turns its wifi radio off and I have to manually turn on wifi, then manually connect to a nearby access point. As I move through the house, rather than connecting to an access point with a better signal, it shuts the wifi radio off, altogether.
The G4 has shut its wifi radio off while I've been in the process of selecting a wifi access point. It's shut its radio off right after I've selected the access point I want and while I'm booting up the web browser.
Today, at work, the G4 is continuing to seemingly randomly shut off its wifi radio. When I manually turn it on, then select the access point, I find the phone has forgotten the password.
Very frustrating.
As an experiment, I have now shut off mobile data, to see if that will coax the G4 to seek and maintain its wifi connection. But there's no way I'm going to spend my day turning off or on mobile data, wifi radio, etc. I'm already manually turning Location on and off, to preserve battery power.

had wifi issues on the 2 g4's i've had. sent first one back due to damage to back cover on arrival. Glad its not just me having wifi issues

Having these issues as well. Rebooting my router sometimes stops it from happening, but quite frustratingly, the phone gets very hot (and discharges quickly) as a result. Have had a hot, dead phone before.

Most of the WIFI routers have different type of connections G / N / B, The N type is not a !00% compatible with our G4, therefore I suggest you to change to B/N, after I change the protocol, I havent see the WIFI issue so far.

I had Wi-Fi disconnects because I had turned on the advanced option to automatically swap to Mobile data on weak Wi-Fi signal. After that was turned off, the Wi-Fi worked as it should.

Where is it said that our phone isn't compatible with N?

I found that disabling ipv6 on wlan0 fixed my slow wifi issue, but still getting the disconnects. (it reconnects automatically though)
http://i.imgur.com/HUDYd71.png - I have a script to disable ipv6 at every wifi connection.
Every instance of SManager is my wifi reconnecting randomly in the house yesterday at my desk.

I have had this issue on my H811 since new. It does it more on 5 Ghz than on 2.4 Ghz, but it still happens. It's more common at home with my Asus router than at work with the Cisco APs they use.
After the latest update I have noticed that the iPod touch I keep in the car disconnects from the hotspot on the phone way too often. This never happened with the previous build, but I also didn't have xposed installed before. Has anyone else noticed any issues with their hotspot?

I got an LG G4 on Friday in the UK and it is running version 10D.
I am encountering this issue and I am finding it extremely annoying - did anyone find a resolution?
It is so frustrating it is getting to the point where the phone will be going back for a refund. It does it at any location with WiFi I go to, so I know it isn't a configuration issue on my WiFi at home.

I'm having this issue too all of a sudden. First thing I noticed was excessive battery drain. But every few minutes it connects to a different ap in my house. Other phones and devices don't do this. Time to dig.

No mobile data when leaving wifi.

On different (clean) stock roms, both mm and ll, data doesn't work when I leave my wifi's range. I have to toggle airplane mode to get it to work again. Tried "switch automatically" in wifi settings and "aggressive handover" in developer section. I found g2 and g3 owners with 6th same issue, but u don't find a proper solution, besides managing this using tasker. The issue appeared suddenly and persists on every rom I try. H815

Snap.
Have the same problem with mine.
It seems to eventually pick up data, but this could be anything from 5-30 minutes are leaving the WiFi connection.
Airplane mode on/off fixes it sometimes, but others I have restarted the phone with no change.
Anyone have any ideas how to fix this?
LG G4 H815.
Android 6.0.
Software version V20g-EUR-XX.

Same issue here, which started suddenly with no obvious reason.
Anyone?

Wifi after sleep?

I have a question. I have "keep WIFI on during sleep" option set to "Never".
When I wake up my phone from sleep after 30 minutes or more of not using it, the wifi does not reactivate itself (it's off, no icon in statusbar), but when I go to settings, it says that Wifi is enabled. Just like in the picture below...
I want to know if this is normal or what? Happens to me on both stock and custom rom.
EDIT :
I fixed this by putting my Wi-Fi frequency band from 2.4 GHz to "Automatic" in advanced wifi settings. Htc and google really need to fix their ****!
I also disabled ipv6 in my router settings, not sure if that helped

Sadly for you, it works as expected for me. I let my phone sit for about 40 mins hoping I wouldn't get a text. Picked it up and the Wi-Fi turned on and connected right away.

This is just plain weird for me. Not a real problem, but strange, maybe has something to do with my wifi connection (router).
Thanks for the reply!

Just confirmed that one other guy that just got the phone has the same issue.

I have had the WiFi Frequency Band set to Automatic since I got the HTC 10. I came looking for this topic because of what mine does. When I wake up the screen, there is often a message on the screen "wifi has disconnected", and it will show connected to mobile data in the notification bar. It usually will reconnect to WiFi within a few seconds. But it is annoying, so I am looking for a fix, if there is one. I turned on the setting to keep it on WiFi during sleep a couple days ago, but it didn't change this behavior.
From what I am reading here, this sounds like it is common to the HTC 10 regardless of that setting. I am therefore thinking perhaps the "wifi has disconnected" message is actually left over and still on the display from when I turned the display off? But what I don't understand is that I get notifications such as incoming email and hangouts messages while the display is still sleeping. Unless those are coming via the mobile data connection. Perhaps I should try turning off mobile data and leaving wifi on to test if it still does that, but obviously leaving the mobile radio connection off is not desireable, even if that did help. Does the HTC 10 silently always switch to a mobile connection and turn off wifi whenever the screen is off, meaning that keep wifi on setting is flawed?

No. You probably have "Auto-switch to mobile network" enabled in advanced wifi settings.

Thank you for replying. The only 3 boxes I have checked in WiFi > Advanced are as follows:
WiFi Notification
Show Wi-Fi pop-up
Hotspot sign-in
All the other check boxes are blank.

So I have similar problem. When I leave the house it switches to mobile network just fine. When I come back home it doesn't auto connect until I turn on the screen. My advanced wifi settings are below with basically nothing checked.
I agree this is a serious problem and for me I have no mobile network at home and depend on wifi and hangouts for voice calls.
Just curious what firmware is everyone on? Mine is 1.91.617.1.

This thread discusses it quite a bit, mentioning different settings changes to try.
http://forum.xda-developers.com/htc-10/help/wifi-issues-htc-10-weak-signal-fail-t3368165
I tried some of these changes, and things seemed better today for awhile, until I found out my phone actually wasn't getting the internet over the solid WiFi connection to my network. :/ I had to undo all the changes so I could get back online with it.

Interesting. Mine was already on Automatic. I never touched it.
