[Google Pixel 3 XL Questions & Answers] wckcol:
Okay I am having a strange problem and I have run out of ideas (and so has Google). On my new Pixel 3 XL, it is up and running smoothly with one giant issue. Most non-stock apps (Netflix, all amazon apps, Zedge, etc) cannot connect to the internet when using WiFi. All the stock(youYube, google play store, gmail, etc) apps that I have tested can connect over WiFi. All of the non-stock apps CAN connect over the cell networks (Project Fi). ALL other devices I have, including the Pixel 2, work 100% fine over WiFi and cell network.

All routers, phones, apps are up to date.

I have tried everything that both I and google can think of. My ISP is Frontier Bonded DSL modem (I have no choice where I live but get okay speeds 22Mbps).

1) Factory reset everything (router, phone, even my modem)

2) Use the router and WiFi built into supplied DSL modem (modem is only 5 months old), same issue

3) New TP-Link router, same issue

4) Used an older Netgear router, same issue

5) Reconfigured routers as WAP, same issue

6) Reset, re-entered everything on phone, forgot networks, uninstalled, re-installed all involved apps, cleared caches, etc, etc.

7) Tried different forms of encryption, AES, TKIP, same issue

8) Changed from WPA to WPA2 to none, same issue

9) Tried different DNS servers, same issue

I was on the phone with Google for 4+ hours to no avail. Again every single other device I have, other phones, streaming devices, Amazon fire, etc, etc all work 100% Only the Pixel 3 has issues. Any hints, tips, or tricks appreciated.
[Google Pixel 3 XL Questions & Answers] Ilikepizzaskolvikes:
Same here!

I'm having the same issue. CenturyLink is my Internet provider (VDSL2 connection), and Project Fi is my cellular network. I made a post on Reddit regarding this and found a small amount of other people experiencing the same thing. Since I'm a new user I can't post the link to that discussion, but if you search my username /u/ilikepizzaskolvikes you should be able to find that discussion. So far it seems to be affecting Frontier and CenturyLink customers. Connections made from a house using Comcast worked as expected...

I've tried everything you've tried. I did get it to work by changing my modem (Netgear D6400) from bridge/modem-only mode to modem/router mode. When connected to the modem's WiFi both my phone and my wife's Pixel 3 apps started working correctly.

Unfortunately, that isn't a good solution for me since I work from home and for whatever reason my Netgear D6400 doesn't handle my work VPN traffic unless it is in modem-only mode.... So I'm back to square one here...

I have the same issue with Office 365 work emails and Netflix. It works just fine over LTE and using my work Wifi but it will not connect using my home wifi. I have a Netgear R9000 and Netgear Orbi. I have spectrum Internet.

I had a mystery problem with wi-f and no connectioni, and it turned out to be "Hidden SSID" and how android 9 handles it differently than android 8 !

hint - you have to scroll down...

( hope this helps )
[Google Pixel 3 XL Questions & Answers] samnada:
Questions: Did you try booting the phone in safe mode? Didn't see that in your list. Also, are you on the Nov update?

Sure hope you get this figured out, and report back if you do. I have no issues with my Pixel 3 and home wifi, but I travel a lot and use many different wifi networks, so could easily be vulnerable. Thanks in advance for any insight.
[Google Pixel 3 XL Questions & Answers] DrUnkeN_TiGeR:
I have this same issue so much so I'm thinking of returning it. You can't use the downloaded apps in safe mode.

I just called tech support she told me Google is aware of the issue and is working on a fix no eta. Take with grain of salt.
[Google Pixel 3 XL Questions & Answers] samnada:
I'm using Amazon Music and Prime Video just fine. Do they count?
[Google Pixel 3 XL Questions & Answers] DrUnkeN_TiGeR:
I can't log into amazon shopping app, Netflix, Skype of business, zedge and my credit card billing app that's all I have found so far

I'm thinking about sending it back and waiting on Black Friday to see if they are going to do in sale if not may go with Google for unlocked bootloader
[Google Pixel 3 XL Questions & Answers] samnada:
Seems odd. I can login to Amazon shopping, Music, Prime Video, and 2 different credit card/bank apps on my home wifi connection. You think it's the Pixel 3 that's causing your issue?
[Google Pixel 3 XL Questions & Answers] DrUnkeN_TiGeR:
Yes my wife has a pixel 1 and I have an s7 through work and have no issues
[Google Pixel 3 XL Questions & Answers] samnada:
So you think it's a HW problem with just some Pixel 3s? Wonder if there's some connection between this and reports of some VPN's constantly disconnecting. My VPN works fine as well. One other thing I saw is when I connected to my Spectrum streaming app to watch TV I got a message that I had to turn off USB debugging. I normally leave it turned on, and it hasn't caused problems with any of the other apps I listed, but perhaps that's a setting difference. Just some random thoughts.
[Google Pixel 3 XL Questions & Answers] morpheo996:
Thank you.
[Google Pixel 3 XL Questions & Answers] DrUnkeN_TiGeR:
I believe it's a software issue not playing nice with some routers
[Google Pixel 3 XL Questions & Answers] samnada:
Ok, that makes sense. Hope there's a fix soon.
[Google Pixel 3 XL Questions & Answers] zopostyle:
I had the same problem, and tried everything as you did. Last thing I did was to replace my routers firmware to WRT, It stopped.

I have an Asus AC3200 original, and updated it to Asuswrt Merlin.

But as you said you tried different routers, don't know what to suggest...
[Google Pixel 3 XL Questions & Answers] j2fast:
I've tried safe mode, etc. as well as current updates but still no joy. I've been going back and forth with Google support for a couple of weeks. They are sending me a new phone but like [MENTION=1071708]DrUnkeN_TiGeR[/MENTION] I think this is software, not hardware so I'm assuming this won't fix the issue.

I just came across this today. So I'm going to play around with MTU settings tonight and see if it makes any difference.

My bonded dsl modem from Frontier won't do bridge mode apparently, so when the new phone doesn't change anything my plan is to see about getting a modem that will do bridge mode so I can put a different FW behind it.
[Google Pixel 3 XL Questions & Answers] DrUnkeN_TiGeR:
Frontier? I feel your pain.
[Google Pixel 3 XL Questions & Answers] j2fast:
Tell me about it, I know the lead engineer in my area so well from all the outages over the years that I feel like I should invite him to family dinners and start exchanging Christmas cards. :rolleyes:

Just ordered the 3 xl from Google $200 off couldn't resist
[Google Pixel 3 XL Questions & Answers] radada:
Another new Pixel 3 owner with the same problem here.

The MTU thing was a good hint.

Though I don't know why the Pixel is more sensitive to it, for me it looks like it is Amazon's fault:

Their servers (or firewalls) don't like to get fragmented packets and drop the fragments.

(And Netflix uses Amazon servers, so the same problem).

In my case, my internet provider uses PPPoE and so the MTU is 1492.

If one of my devices send packets with 1500 bytes length, they are split into one with 1492 byte and one small one that contains the rest of the payload data.

And I think the second one doesn't get though Amazon's firewall.

Though that might not be a reliable test, you can do a ping to amazon.com with a payload size of e.g. 1600byte and you will see that the answer is just the size of the first packet/fragment.

Anyway, I solved this by additional MSS Clamping on my router that runs OpenWRT.

By default it already does adjust the TCP MSS on outgoing SYN packets so servers don't send you packets that are to big for your MTU.

In addition I now let it also do on incoming SYN packets so my devices know that they have to send smaller packets and there is know fragmentation.

To do this, you have to add a custom iptables under "Network -> Firewall -> Custom Rules" like this:

Network -> Firewall -> Custom Rules

iptables -t mangle -A FORWARD -i pppoe-wan -p tcp -m tcp --tcp-flags SYN,RST SYN -j TCPMSS --clamp-mss-to-pmtu

Note that "

pppoe-wan

" is my wan interface and has to be adjusted.

You can look it up at "Status -> Firewall Status -> Table: Mangle" (the new rule should appear here too afterwards).

This seems to work fine for me.

And I'm also confident that it is a improvement in general, not just for the Pixel+Amazon combination.
[Google Pixel 3 XL Questions & Answers] mmellis:
This fixed the issue for me.

I have a pixel 3 and my home wifi is an edgerouter x sfp for PPPoE on CenturyLink gigabit fiber. I'm using an ORBI in access point mode for wifi.

I couldn't get amazon and netflix to work on my home wifi and tried just about everything. I disabled ipv6 (other threads said this worked for them) but no luck. Finally found this thread and what you suggested above solved the issue.

edgerouter has a TCP MSS Clamping wizard. I set the MSS to 1452 and my apps started working immediately.

Thanks
[Google Pixel 3 XL Questions & Answers] coalh:
Thank you so much guys! This resolved my problem.

I'm using an Ubiquiti ER-X as well and the hint with the TCP MSS Clamping wizard was awesome!

[Google Pixel 3 XL Questions & Answers] Dread2000:
Same problem here on my pixel 3 XL. Even Tweeter is not connecting. Did anyone found any fix
[Google Pixel 3 XL Questions & Answers] stickdart:
I have the same router on frontier. Both Pixel 3's in my house are having the same issue but none of the other devices in the family have any issues. I can't even get to amazon.com on chrome on the phones. I did find Advanced -> Connection -> MTU and was able to set it to manual and then set the max size to 1452 but it didn't appear to fix the issue. Does anyone have any other thoughts for other accompanying settings that might fix the issue since this router doesn't have the MSS wizard y'all were talking about?
[Google Pixel 3 XL Questions & Answers] DrUnkeN_TiGeR:
All we can do is hope and I found the mtu too no-go
[Google Pixel 3 XL Questions & Answers] LeggMD:
I had the same issue with my new Pixel 3 XL. I have frontier internet service. All I had to do was update my modem box thru frontier. My old box would not allow me to load Zedge or Amazon Shopping app. New box fixed the issue.
[Google Pixel 3 XL Questions & Answers] DrUnkeN_TiGeR:
How did you force update? Or you mean you got a new modem? Are you using NVG443B or the westell? Do you have regular wifi and 5g or no?
[Google Pixel 3 XL Questions & Answers] nilknarf:
Just to say this was exactly my issue with the Pixel 3. Just tweaked the firewall on my router and all was well with the Amazon app. Thank you so much for posting this! :good:
[Google Pixel 3 XL Questions & Answers] DrUnkeN_TiGeR:
What did you tweak
[Google Pixel 3 XL Questions & Answers] nilknarf:
The added the exact same iptables rule that radada posted, but with the correct interface name for my router, which was ppp0 in my case.
[Google Pixel 3 XL Questions & Answers] DrUnkeN_TiGeR:
Do you have a frontier router

Which would I chose I'm lost?

I talked to google today and they said that their working on a fix for the problem
[Google Pixel 3 XL Questions & Answers] DrUnkeN_TiGeR:
An update that I just did fixed the issue
[Google Pixel 3 XL Questions & Answers] Dread2000:
Now??? Whaat? Do you mean the January security patch?
[Google Pixel 3 XL Questions & Answers] DrUnkeN_TiGeR:
I'm running January patch and on this build
[Google Pixel 3 XL Questions & Answers] Dread2000:
I'm running on the same build number but the issue is still there. I can't access Amazon.com. Snapchat, Tweeter and Netflix are not working on WiFi
[Google Pixel 3 XL Questions & Answers] DrUnkeN_TiGeR:
Hmm wonder if my router update instead of the phone
[Google Pixel 3 XL Questions & Answers] Dread2000:
I think it's your router because Google is saying that they know about the issue and the fix is yet coming
[Google Pixel 3 XL Questions & Answers] DrUnkeN_TiGeR:
Netflix still doesn't work
[Google Pixel 3 XL Questions & Answers] Dread2000:
We probably have to wait another month. Until February security patch.
[Google Pixel 3 XL Questions & Answers] zerofun21:
I have the same issue but with other apps. I even replaced my first pixel 3 XL just to be safe... still have the issue.

I have come to the conclusion its my google wifi, or possibly how the phone manages apps ? The app that always seems to be an issue is DC Universe (streaming app) and lately I have been having issues with messenger... it doesnt want to sync / connect up with my pixel book most of the time... no idea whats going on.

I noticed that after having the phone for a while it seems to warm up.... when i first started using it the app wouldnt connect at all when i was on wifi... now it seems to connect about half the time, or if i switch to LTE, when WiFi comes back on automatically the app will continue to work.

I still love my pixel 3, my pixel book and my google wifi ! They are just a little handicap at the moment. =(
[Google Pixel 3 XL Questions & Answers] Expliciate:
Running January patch and I still had this issue on certain apps. (Twitter, snapchat, reddit)

Luckily my ER-4 had TCP MSS Clamping as well and setting to 1452 solved it. Thanks!
[Google Pixel 3 XL Questions & Answers] DrUnkeN_TiGeR:
So I unlocked bootloader and rooted and if course formatted and it isn't working again that's odd
[Google Pixel 3 XL Questions & Answers] El Daddy:
I really hope Google fixes this issue with the February update. I really don't want to have to buy a new network setup...
[Google Pixel 3 XL Questions & Answers] DrUnkeN_TiGeR:
Yes this is getting annoying I have crappy service at home but if I want to use Amazon or a few other apps I have to turn off WiFi since it's apparent no one has fixed this that uses a frontier dsl router.
[Google Pixel 3 XL Questions & Answers] alvarorojas4:
Same problem here with a Pixel 3.

I'm not in US but I have DSL with Movistar and having the same problem
[Google Pixel 3 XL Questions & Answers] El Daddy:
Installed the Feb. OTA. The issue is not fixed. I'm not happy.
[Google Pixel 3 XL Questions & Answers] DrUnkeN_TiGeR:
I just came to the post to ask this
[Google Pixel 3 XL Questions & Answers] El Daddy:
After a long chat with Google Support and 3 transfers, they asked to work with me to help identify the bug. Hopefully we make some headway. I'll keep the thread updated if any breakthroughs happen.
[Google Pixel 3 XL Questions & Answers] hugoNL:
Thanks. I hope you are having more luck than me. My chat with support eventually escalated to the floor manager -- but what I say about MTU and fragmentation seems to go over their heads.
[Google Pixel 3 XL Questions & Answers] Dread2000:
February security patch didn't fix the problem but i recently switched to Unitymedia from Vodafone and the problem was fixed. I live in Germany.
[Google Pixel 3 XL Questions & Answers] alvarorojas4:
Came here to say the same :(
[Google Pixel 3 XL Questions & Answers] El Daddy:
Anyone with root access have this issue? I'd like someone to test changing the value of

/proc/sys/net/ipv4/ip_no_pmtu_disc

to "0"
[Google Pixel 3 XL Questions & Answers] DrUnkeN_TiGeR:
Has this been tried
[Google Pixel 3 XL Questions & Answers] El Daddy:
I haven't heard from anyone yet. I'm pretty sure that the Pixel 3 having the value of 1 here is disabling "do not fragment" and is causing the problem. I have passed this info on to Google and all I got back was a thanks and to be sure to keep my Pixel 3 XL up to date... For reference, my Pixel C doesn't have an issue and the value is set to 0.
[Google Pixel 3 XL Questions & Answers] DrUnkeN_TiGeR:
set /proc/sys/net/ipv4/ip_no_pmtu_disc 0

correct line?
[Google Pixel 3 XL Questions & Answers] MWlfrd:
I've been looming around this thread for months in frustration because my Pixel 3 XL has had the wifi issue. El Daddy's theory is correct! Downloaded es file explorer and changed ip_no_pmtu_disc to 0 and all apps FINALLY work on wifi!
[Google Pixel 3 XL Questions & Answers] El Daddy:
That's correct.
[Google Pixel 3 XL Questions & Answers] DrUnkeN_TiGeR:
Didn't work

I too have this issue. It is annoying.

I have been using a workaround since I got my Pixel 3 XL at launch which works perfectly (for me). Although it is a workaround, it has resulted in me not really being bothered about the issue anymore.

For anyone who is interested, this is what I have done to mitigate/solve the problem:

TLDR: Use a proxy. I use the proxy offered as part of my Private Internet Access (PIA) VPN subscription. The proxy is based in the Netherlands (I don't think the location is relevant).

The method I use on my device is as follows:

I have been a long time user of Tasker/Macrodroid and Adguard

As this problem only manifests when using WiFi, I set up Tasker or Macrodroid to automatically turn on Adguard when I am connected to WiFi.

Inside Adguard, I add my PIA VPN proxy details in the relevant section.

Boom. All WiFi traffic is routed through the proxy and all apps that used not to work (Amazon, Netflix etc) now work perfectly. The added bonuses are that my traffic is protected and I see no ads.

Netflix without proxy (note the missing VPN icon in the statusbar):

Netlfix with proxy (note the VPN icon on the statusbar):

I'm sure there are other ways to connect via proxy, but this automated method works well for me.

FWIW, I do not have a rooted device, but a command line option allows you to enable/disable MTU path discovery when using `ping`.

For me, it makes no difference pinging with or without MTU discovery: all fail.

I'm no Dev but what does this have to do with it
[Google Pixel 3 XL Questions & Answers] nick_22:
What happened to me was, while browsing or watching videos, I observed a cross icon on Wifi very frequently. And the issue seemed to be this, as mobile data was always set to active, data related stiff tried switching to mobile data. After I turned this off, everything seems to be working fine now.

It's weird I have the value set to 0 and amazon app works but none of the other apps work hmm it's anyone else having this issue
[Google Pixel 3 XL Questions & Answers] cmlusco:
Not sure of this is the same problem, but I had an issue where alot of the time apps would load their data very very slowly or time out all together on wifi, but not on the network. All other network devices were fine. My pmtu discovery was already set to 0 and i disabled always keep network active with no luck. So i started messing with all the setting, and found that disabling private dns seems to have fixed my issue all together.

Had a similar issue over here in germany, but only with open Hotspots

whenever I tried to connect to an open hotspot, it just kept staying at "connected, no internet"

usually I would have been redirected to an authentification page where I can enter credentials, or just say "connect now" but this never happened.

Now it's working again, but as far as i know there were no updates recently, the only change I made was a newer Magisk version (from 18.0 to 18.1, and now, sadly, back to unroot, because of my banking apps ....) but hey.... wifi is working fine now :shrug:
[Google Pixel 3 XL Questions & Answers] DrUnkeN_TiGeR:
You can hide root in magisk to select apps
[Google Pixel 3 XL Questions & Answers] dvsk69:
Thank god I'm not alone here with this annoying issue. All my other phones at home work flawlessly with the same WiFi router settings and my Pixel 3 seem to not load apps properly at all.

Twitter, Netflix are the two most impacted and other apps are intermittent. Turning off WiFi and using LTE immediately fixes the problem.

Interestingly, WiFi at my office works without any issues on my Pixel 3. ?
