Hi-
Just installed LineageOS 17.1 on my Moto G7. When I enable Hotspot, my phone loses mobile data altogether, and I can't get it back until I reboot. I can still ping google DNS servers (8.8.8.8). When I try to use Private DNS to dns.google, I get "couldn't connect". So, it seems like the hotspot is interfering with the phone's ability to resolve hostnames somehow.
Mobile data works fine all other times, and I spent a couple hours on the phone with my carrier, and there's nothing wrong on their end (phone also reports it's still connected to the LTE network).
Any help would be appreciated.
Thanks!
Update:
Just did the August 16 update -- no change. Here's some more information:
When hotspot has killed internet access on mobile data:
I cannot ping any hostname (I cannot ping websitename);
I can get DNS resolution (I can resolve websitename to 172.217.9.196);
I can ping 172.217.9.196;
BUT, I can't get my browser to load a webpage with 172.217.9.196 (on my phone; it works on my computer).
I also appear to be connected to the local cell towers -- just can't get access to their internet.
None of this goes away when hotspot is turned back off, although if I turn wifi on, I can get access to internet again.
Weird stuff -- especially the DNS resolution that works but doesn't allow me to load a page.
Actually, it looks like I am NOT getting DNS resolution for sites other than google. Instead, I get something about a Canonical name ....

My Xoom usually disconnects the VPN immediately after opening any file from an SMB Share using ES File Explorer. I preferred Astro but the SMB addon doesn't work with Honeycomb yet. A variation of different vpn clients all do the same, as soon as data is done being transferred from a single download, the VPN will disconnect.
Is there a workaround for this? It would be great to only have the VPN connect when resources on the network were accessed or written.
I haven't found a workaround or solution to keep the VPN up and stable.
(btw, this is a typical MS 2008 PPTP on a Windows Domain)
At the moment, I'm having to reconnect after every file transfer- again, the wireless network doesn't seem to make a difference (although the 3g connection is obviously poor)
I've done a little troubleshooting on this in the last few days using the magic of wireshark. MS PPTP Server, makes the connection and then drops after SMB traffic is attempted, as well any website will not load, and no email / communication will work.
I believe this fully involves a Default Gateway setting on the Xoom, being it's a client-side setting and the Xoom doesn't appear allow that option to be changed (silly that it's missing, imo).
When I make a connection, Verizon's firewall policies see a foreign IP return traffic at some point on their network and blocks the transmission completely, eventually causing PPTP to timeout.
Here's a good read on how to get around the restriction:

I myself have been on the phone this morning regarding this issue, I'm up to about a 3rd level of tech support and he is trying to tell me 'nothing is blocked at all on the Verizon network'...
I'm awaiting a call back now... at which I'll try to show him the above site/resource and maybe he'll move me to an unrestricted IP block. We bought 3 Xooms with the intention of working remotely in the field using PPTP- 4 more coming soon---
At this point, I'm still tempted to go back to Sprint and just wait on their Xoom release.
*btw, you can verify the above by tethering to the Xoom and changing your default gateway on a laptop/pc, the connection will work fine.

AH-HAH!

Apparently this is a known issue.

I've posted about this problem in this thread:

I've tried it on every version of Android since 2.1. I tried it with my Xoom on 3.0 and the problem remains. It appears to be a pretty low priority for Google.

Turned off encryption on the server and all was well. I can't believe google let that slide... !?
I guess I'll transition to a L2TP VPN...
I just bought a Nexus 6P, rooted it, and installed PureNexus (Android 7.0.0). At home my WiFi works perfectly fine but I have issues at work.
Little background on our setup at work, we have 2 different wifi networks. One is a guest network with certain sites blocked at the firewall but nothing else really unique. The other is the main network with no firewall restrictions but you have to install a certificate to allow SSL traffic to be decrypted. Without the certificate you can go to any non-SSL sites, but secure sites will not load.
I'm able to connect to the guest network with no problems, but anytime I try to connect to the main network my phone says it has no internet connection. I'm able to get to internal resources on our network and the web browser actually does allow me to go online, but other applications won't. I've tried without the certificate, tried installing the certificate as WiFi and VPN/Apps but it doesn't seem to make a difference. Before the Nexus 6P I had an iPhone, which worked perfectly fine on the main network with the certificate. The last Android I had was on KitKat and it worked fine with the network configuration at work. Other people with Android have no problems with the network, but nobody has Nougat, yet. Any ideas on what's going on here or what I can do to fix it?
Thanks in advance for any suggestions or help you can give!
TL;DR
Blocked ads (Google adsense specifically) via router with urls and successful​ly works on every device connected through router. G6 is still able to pull ads unless I proxy my wifi to a local server within my network. Is there a setting I missed that is causing the phone to be tunneling traffic even behind my own network?
Long story
Example AndroidPolice.com will normally have ads at top of webpage and in between posts. I blocked the ads urls via my synology router and works on all devices(10+ devices all varying manufacturers) EXCEPT the G6.
My suspicion is that the data over WiFi is being either proxied or tunneled somewhere else but I currently have no way of fully verifying how or where to. I will try to look into it when I have more time.
I run my own home proxy server and if I set the wifi connection with the local proxy address then reload the website all Google Adsense urls are blocked again.
I have checked all the settings I could and short of a factory reset, all diagnostic help, send data to improve, ect have been either turned off or disabled. Even put it in airplane mode and turned off wifi calling. I tried to remove as much LG and T-Mobile software as possible. Still didn't work.
If anyone could test my theory or help out please do.
I have the T-Mobile version running March '17 Patch.
If there is a setting I'm missing, perhaps at the setup? Let me know.
Apologies is this is posted somewhere else. I couldn't find it and this is my first carrier phone in 10yrs.
I guess I bought the wrong tablet for my kid because the stock tablet family management is terrible and no root. I tried to setup a limited version of my adult account with sideloaded google play and blokada but blokada stopped working and the app icon disappeared(or never appeared and I didn't notice till it stopped working). It seems blokada also broke my wifi settings as the network connects but no internet. I tried to reset to factory but I guess that does not reset whatever blokada changed because the network always has no internet. No vpn settings anymore... guess that got changed. I am able to tether to my phone hotspot and get internet but not my home wifi. I suppose I could change the SSID but then I would have to reconfig 2 dozen devs not fun. How can I get the stock ROM? Or, how do I get my wifi settings reset?
created a guest network with a new ssid but same no internet, it dont like this ap for some reason.
Yep, something buggy with 8.8.8.8 haunting DNS entries. Noticed my phone was giving out ip6 dns so I turned on ip6 for my local network and the crap tablet is working now.
Previously, I had no issues with AirMore on my Redmi Note 7. Recently, I can no longer connect by scanning the QR code. I've tried using another Xiaomi phone with the same version of Android and MIUI (both have Blokada as the only thing modifying their network), and it works properly with AirMore. I've also tried the method where you input your phone's local IP address to connect to its AirMore server. Works on the other phone, but not on this one.
I've also installed AirDroid, and it only manages to connect via the remote connection mode (over the internet), which limits you to 200 MB transfers in the free tier. So there's gotta be an issue with the phone isolating itself from the network. I do not remember modifying its network access in any way, other than using Blokada to block ads system-wide. I've tried uninstalling Blokada and it didn't help, while it works normally when Blokada is active on the other phone.
Can anybody help me diagnose what the heck is happening here?
Any help? I've managed to determined that the phone refuses all local incoming connections for some reason. I really can't afford a factory restore, I have so much installed and configured just the way I want it.
