[Q] Wifi is connected but no traffic, WTF?

I thought at first my router was having issues, but that is not the case. I have confirmed zero router issues by using 3 laptops and 2 other phones (Samsung units) to connect to anything I want.
If I connect using my M8 (Verizon), it connects with no issue but I have no real internet connection. The signal strength is -40 so that is not the issue.
I have tried multiple restarts, multiple networks, and multiple SSID's. I even tried forcing it to 2.4 or 5 Ghz and nothing at all seems to work.
Is this a known issue? I am coming from a long line of Samsung stuff so I am not up to speed on the quirks with HTC stuff. Your assistance is appreciated!

Stock, custom ROM, etc?

This is a stock ROM with weaksauce root and nothing else.

Ok, so I just connected to the wifi at my office and it appears to be working just fine, but it took about 15 minutes form my phone to recognize that the network even existed.

I am pretty sure this phone is just a piece of crap. About 2 hours after my last post it started doing the same thing (at work). I just got home and did a 100% fresh reset of both my router and my phone to eliminate any possible configuration issues and it shows that it is connected on the phone, but the router is not seeing that it is connected... how the hell does that work?

Since you've determined its a piece of crap, sell it and get yourself a iPhone. Why bother trying to get it to work.

When you connect to your router what details does it give in the phone WiFi settings for that connection?
Also which router do you use?

Intermittent WiFi disconnects

Has anyone been having any issues with the WiFi randomly cutting out?

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.

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.

WiFi keeps disconnecting and reconnecting.

Title explains most of my issue but whenever I want to do anything on my phone the WiFi always keeps randomly disconnecting and reconnecting on my G4, when i go to my WiFi settings while its disconnected it just says the network is saved and then when i connect to it, it instantly disconnects. If anybody has any solutions its would be gladly appreciated.

I have the same issue. One additional info I have is if I look at wifi immediately when it disconnects, it shows something like "Avoided poor internet connection....." even though signal strength is Excellent. It feels as though LG reduced the threshold of developer options' "Aggressive Wi-Fi to Cellular handover". I have that option OFF.

I recently got a replacement Verizon G4 Hardware rev1 because of the constant horrible Qi Charging meltdowns. My new G4 seems to have a faulty Wifi module or something because my wifi will suddenly just stop working (even though still connected). I also get weird toast messages that is is disconnected/connected, when I am sitting a few feet away from my router.
My router is a newer AC router. The wifi analysis shows me on a good channel. None of my other devices (or previous G4s) have an issue.
I have 2.4 and 5ghz enabled so perhaps it is disconnecting and reconnecting to change bands. I haven't gave it much thought because honestlt I do this crap for work and been lazy. I think there is an option to use 2.4ghz only. That may prevent it bouncing occasionally.

I get the same thing. Very annoying

I just noticed this thread. My WiFi seems to get into a state where it does this too. What I've found is
1) it only does it when connected to 2.4Ghz WiFi. If I use my router's 5Ghz network it stays connected. Unfortunately the range of 5Ghz is not good enough for me to use this all the time.
2) it only happens when Bluetooth is enabled. If I disable Bluetooth then my WiFi stays connected. This is annoying to have to do and more of a workaround than a fix.
3) WiFi works perfectly in Safe Mode
I'd be interested to hear if this is the same for others who have this issue too.
Like I said, my phone seems to go through phases when this occurs, then (seemingly randomly) it fixes itself and works for a few days/weeks, but then it happens again. The state change seems to be triggered by installing/uninstalling apps but I can't make this happen at will.

Same issue here, very annoying. All other devices stay connected to WiFi just fine but this LG G4 keeps disconnecting and reconnecting. I have an Asus AC router. The phone is connected to the 2.4 Ghz band. Not sure what to do...the phone just got an update (marshmallow)...the router is updated and working fine with all other devices.

Me too. Even when signal is great. This is terrible.

I know this is a pretty old thread, but I was just having the same issue on my g6. I found that it was because I disabled some of what I thought was just bloatware. By enabling both the LG "SmartWorld" app and the at&t " Smart Limits" app I was able to get my wifi working properly again.
I am not sure which one was the culprit, but I hope this helps anyone else digging back for a solution.

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:

WiFi Issues

Is anyone having wifi issues on the March update? I'm trying to determine if it is the phone itself or my wifi AP.
Thanks!

Yep sorry. Forgot to define it. The WiFi randomly disconnects for a few seconds and connects back to the network.

I will admit the Wifi is kind of squirrely on my phone.
Not in connection but in performance.
i havent experienced disconnects accept with wifi I KNOW to be crap.
i do experience choking where nothing is moving quite often.
Does this happen to you on all networks?
I really like this app to keep tabs on that sort of thing, https://play.google.com/store/apps/details?id=info.kfsoft.android.TrafficIndicatorPro

I've had that happen before intermittently. It also happened with my Nexus 6P. I think a full wipe/reset fixed it for my phone.
You could also try to forget the WiFi connection, and then reconnect to it. That may help. I also tried power-cycling my router at home.
Good luck.

Ok so I use Unifi UAPs at my house and I have read about this issue on the unifi community forums a little but some people are saying it began happening with the February update. Apparently the claim that disabling ipv6 fixed the problem but I am reluctant to accept that as a solution. Just wanted to see if this is a broad issue or something I should take to the UBNT forums.
I have only had the phone since February (thanks verizon) so I can't comment on performance before that. Before the pixel I did have a nexus 6p that was fine on my connection but I have noticed some connectivity drops too on it recently. However I don't use it as much as the pixel so I can't say for sure.
Thanks all!

I only connect to the WiFi at my house since I have plenty of data so I'm not sure if it happens on other networks. I also wouldn't be on other networks long enough to test either since it appears to happen sporadically.

I noticed this was a old thread but curious if anyone found a solution? I'm on March 18' update and my wifi connection constantly cuts in & out. Router is a Linksys with Mediacom as ISP. I tried both 2.4 and 5Ghz bands with no luck.
