Networking problems: WiFi, IPv6 - Moto Z2 Force Questions & Answers

Hi,
since abut 3 or 4 weeks I've more and more problems with my Z2. I'm on stock 8.0.0, not branded, pure Moto. My home network is dual stack IPv4/IPv6. IPv6 uses auto configuration and router advertisements, no DHCPv6. My problems are:
WiFi disconnects periodically. I notice this when I'm reading. Then I see WiFi turning off and on again. The next Problem is related to this.
Some times (I thinks with every other [re]connect) the phone does not have a IPv6 address.
Nothing I've found (reset play, clear cache, etc.) helped. Any suggestion?
TIA

Unfortunately, the Z2 does have issues with wifi. Stock or AOSP the heart of the problem is om Moto's side. The only thing that helped (for some) is to disable wifi location scanning in the location settings, setting a static ip addy, and again (for some) use the 2.4ghz network if you have a dual band router. This is by no means a fix, it more like salt in the wound lol. It has helped some, so you might give it a try.

Thanks. In the mean while I've tried some thing I've read in an other thread on XDA. I've split 2,4 and 5 GHz in two different SSIDs. This seems to help. In that thread I've read that this is an issue with the WiFi chip set.
If the problem comes back I will try what you've suggested and report back ...

note 4 wifi issue

ok so i searched everywhere for this and couldn't find a solution. i have a note 4 and it will connect to my home wifi just fine. i can search the internet on it, but facebook doesn't load and neither do certain games and the app market loads very very slowly. when i had my S4, it would do everything just fine. i was at my friends house and connected to his wifi and everything loaded lightning fast. so i know it's a problem with my wifi, i just don't know what.
my modem is netgear and my router is belkin AC 1200
any ideas on what to check so i can fix it? i suck up a lot of data lol
Do a speed test on your wifi with another device to determine if it is your phone or your wifi. How does your phone perform on 4g? Does it do the same thing?
the wifi is fine. i can browse the internet, watch netflix, etc. When i'm on my data, everything loads like it normally would.

Try hard resetting you router and before customizing it(changing SSID, encryption, etc...), test it with your phone to see if its any better.
it didn't seem to help. it's dual band and i tried on both. it wouldn't even load the google play until i switched bands.
any other ideas of a possible fix?

Yes.
I just got my VZW Note 4 yesterday and noticed almost the exact same problem. There is a little bit of info out there talking about things like power saving mode and stuff, but I noticed that my speedtest.net throughput was excellent. My next thoughts were DNS resolution or an IPv6 problem. Turns out my wireless router had a default setting with IPv6 routing enabled, but my ISP does not serve IPv6. You may notice the same kind of initial lag on Ubuntu installs (especially with certain VPS providers) where every single command you issue seems to take ages to start, but then completes quickly. I know how to deal with Ubuntu to force a preference for IPv4, but a locked down Samsung phone is a different matter entirely. Thankfully, I was able to just turn it off in the router.
For my specific router (Belkin AC1200 DB), the user interface has an IPv6 settings page, but the options they present to end users isn't intuitive. I changed my 'connection type' on this page to "Local Pass-Through Only", and my problem immediately went away. Have a look and see if you find anything similar.
Thanks, and good luck!

DUDE!! this is exactly what i was looking for. i think this fixed my issue. surfed facebook briefly and it loaded everything instantly. i'll check more as the day goes on. thanks so much man
Fixed My Issue too!
Hey Guys
Newbie here! I just wanted to say that this fixed my problem as well. I don't usually post as you can tell by my info but this was worth coming out of the dark to reply to.
Now to clarify, I too have a Belkin router AC1200 so it may be specific to those. Anyway thanks for the help and enjoy the fish!
someone sticky this! i have the same wifi issue , i am at work right now but i will try it when i get home! , i hope this works!
I am having this same issue bUT Comcast here uses ipv6 as well,I have a Belkin n1 router what do I do?
---------- Post added at 07:39 PM ---------- Previous post was at 06:50 PM ----------
never mind i disable ipv6 in my comcast modem and it seen to do the trick, any idea why this is happening?
I've been having the exact same issue on my Note 4. for the past week or so. Our router/modem is a DPC3941T from Comcast, and I can't seem to find how to turn off IPv6. This setting was under Connections > Local IP Network. If anyone could help instruct me further, you would be a great help. I'm pushing my data cap for the month as it is because of this >.<
I'm having the same problem too. The funny thing is that I went to the Verizon store to see if they could trouble shoot it and the phone did not work on their wifi network either! I realize now how to access my IPv6 settings in my router and that does seem to fix the issue. Unfortunately I cant imagine very many businesses with wifi networks will allow me to reconfigure their router everytime I want to use wifi.....
I started having this issue when I upgraded to lollipop. My Netgear C6300 AC1750 doesn't seem to have an option to disable ipv6 though. Any suggestions?

WiFi connected-internet unavailble

I have a peculiar WiFi issue in my office where I can connect to the router, however, I immediately receive a message: "internet unavailable". I am using latest stock T-Mobile ROM. 5.01, Build 20E. Other phones have no problem like my Nexus 5 or other people's iphones. Also, I am running a dualboot partition with a nightly on the same phone and it works fine in Cyagenomod.
I've tried this app: WiFi Doctor, and it finally worked until I went out of the office for a few minutes. When I came back I was at square one and what's worse, WiFi Doctor couldn't cure it any longer.
Anyone? Hello? I'm pretty sure there are a few smart people out there.
T-Mobile G3 stock ROM, Android 4.4.2, build D85110m, encountered the same problem in my office. Likewise, no issue with an old Samsung or iPhones.
From what I've manged to find on the internet, IPv6 or the MTU setting might be a contributing factor.
This isn't a fix per se, but voodoo steps of forgetting the network, switching off wifi, switching on wifi, re-connecting to network (staying on the Wi-Fi screen and waiting to see that it connects) works sometimes. Sometimes it fails and tries to re-obtain an ip address and it works after it re-tries several times. All this while I would be on the Wi-Fi screen watching it.
Occasionally, rebooting the phone helped for a while.
All the boxes under Advanced Wi-Fi are unchecked for me.
My G3 is not rooted, so I've not tested to see if disabling IPv6 or changing MTU fixes it. If you (or anybody else) do test it, I'd appreciate it if you could post your results.

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:

Nexus 5X randomly lose connectivity

Hello there,
I am encountering a problem with my beloved N5X...
Since a few weeks it randomly loses connectivity (both cellular and Wi-Fi)
And after a few seconds (sometimes minutes) it catches the network back.
For example:
I wake up the phone for checking messages, and i see WhatsApp saying "searching for messages", no warning icons for network.
Then i try to load a Chrome page, it does not load..
After a few seconds all is getting back to normal and everything loads. (the web page, new messages notifications comes on, etc)
I tried so far:
- Reboot (after a reboot it works normally for a few hours, then problem begins again)
- Resetting network parameters (does nothing)
- Complete factory reset (had 2 weeks problem free then the problem begins again)
- Flashing custom ROM (from Google factory to last Lineage OS 15.1)
For informations:
- No VPN
- No gaming, the phone never heats up
- Good network coverage (both cellular and Wi-Fi)
- No network related apps
- The phone is 3 years old, never felt on the ground
Any ideas?
Thanks a lot for reply, and have a nice day!
I'm having a similar problem since Oreo update, but only on WiFi. On 4G network is working flawlessly but I think is due to carrier network settings on cellular towers.
Every search I made on the web to address the issue finished with a lot of posts read but no decent solution whatsoever, but the other day a reply on reddit made me think and I found a setting on my router WiFi AP section called "Unscheduled APSD (Automatic Power Save Delivery)" and since I disabled it my phone seems working better. I don't know if it's just random luck or it was really the cause of the issue but you can try.
Hope it helps.

Hello,
Thanks for your reply.
I searched everything on the phone that could be wrong and i also ended up that router might be the cause.
I did not found the setting you mention (i'm on Synology router) but i tried to disable the 5 GHz frequency band and use only the 2.4 GHz one.
Since then the phone works perfectly! Although the Wi-Fi speed is a bit slower..
I hope this can help you too!

I was on 2.4Ghz only since a few months but had the issue anyway before disabling uAPSD.
If your bandwidth is reduced is probably because your network is on a "busy" channel, try scanning all the wireless networks around your home (i use wifi analyzer on my phone) and see which are the "busy" channels and set yours on a free one. Bandwidth on 2.4 and 5 ghz should be the same, the pro of the first is a better (wider) coverage of the signal, mostly through walls and the pro of the second is less interference with other wireless technologies and environment at expenses of the coverage.

Well, after a few days i noticed the problem still persist even on 2.4GHz, but less than before..
Unfortunately Synology router does not have APSD option in the Wi-Fi settings.
I tried to put Protected Management Frames (PMF) on "enable - optional", that setting was disabled before.
Wait and see.
Thanks again!

WiFi issues: can't connect to any network anymore [T800]

In the last 6 months or so I have been experiencing frequent wifi issues, regardless of the custom ROM I'm using. Usually some time after a new installation I am unable to connect to the networks I normally use (my home network and the one at work which uses a proxy server). No matter what I do (clear cache, factory reset, change ROM...) the problem persists. In settings a number of random messages are given: secured, disabled, authentication problem, etc. Every now and then I can get a connection (never at work though) but it doesn't last long. Any help for troubleshooting this would be appreciated. I hope it isn't hardware failure since I'm still enjoyng this tablet after all these years!
Mine started having wifi issues off and on a couple of weeks ago. The wifi started to not turn back on after waking it up, at first just in manually turning it off and then back on seemed to work. Last Friday it just wouldn't stay on at all. I would go to the wifi in settings, it sometimes would get stuck saying turning on. I finally did a factory reset on it, it at first seemed to fix the problem, even spent a couple of hours trying to get everything set back up. Then the problem returned, it just keeps turning the wifi off, if i can even get it to turn on at all. I was going to try and use my phone as a hotspot through Bluetooth (not sure if i can or jot, never tried before), but even the Bluetooth won't stay on. So Sunday, after spending way to many hours fighting with it, i went out and got a new tablet.

Have you tried using the Samsung Kies app to flash the latest stock rom, Dont use Odin or other non Samsung approved flashing software.
I have had my T800 for over 4 years and had no real problem with the wifi connection, But i have heard that there can be compatibility problems with some wifi routers, Also try changing the channel number on your router, Auto channel was giving me poor connection on my PC, I ran the inSSIDer wifi app and it said to manually change my wifi channel to channel 1 the clearest channel as other wifi and bluetooth and wifi dongle even you smart gas/electric can cause interference., auto was picking channel 13 for some reason and it fixed my problem.

Thanks, but since it's the router at my workplace there's not much I can do on that side. Question is, are there any specific steps I can take to verify if it's software-related or if the wifi module is just gone?
Wifi and Bluetooth both use the 2.4ghz frequency, So they can interferer with each other and can cause constant disconnect`s, I have seen this many time, Use 5.0ghz on your T800 if you can, Or disable Bluetooth.
Does your wifi work OK on other brands of router?, Or is it just the one you are using at work.
John.
It's kind of tricky to answer: let's say the times this issue appeared it always stareted at work, but then also at home I couldn't keep a stable connection. Once the problem starts, I get no connection at work at all and very difficult connection at home (meaning it does connect intermittently).
UPDATE. After other attempts and a complete restore of stock firmware, I have both wifi and bluetooth not working, constantly "turning on...." but never activating.
