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!

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:
http://jbenisek.wordpress.com/2010/10/05/android-2-1-and-2-2-vpn-pptp-over-verizon/
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.
Encrypted PPTP is broken on Android: http://code.google.com/p/android/issues/detail?id=4706
I've posted about this problem in this thread:
http://forum.xda-developers.com/showthread.php?t=992876
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...
Hi,
Firstly I should introduce myself, my name is George, live in Essex and have a passion for cars and gadgets.
I've been roaming this forum since I had my first android device a HTC Hero and try and use search as much as possible rather than repeating other peoples problems but I am properly stuck with this one..
To be short,
Device Details:
Device: Google Nexus 4
Android Version: 4.2.1
Carrier: Orange (EE)
Problem: Portable hotspot is active and I can connect to it from various devices but there is no data pass through.
Solutions tried:
Changing the APN type to every possible solution mentioned (i.e consumer broadband etc)
Using both open and sercured sercurity on the hotspot
Connecting using everything from another phone to my Google Chromebook and all imbetween
I've read there has been mention of Orange blocking this but most people find this isn't the case and its usually fixed via the APN.
The only thing that looks slightly odd is that an ipconfig on my windows machine(s) shows 192.168.xxx.xxx yet the IP address displayed by my Nexus is 10.166.xxx.xxx and if I ping my Nexus's IP from my machine i do get a response.... (all when connected to the hotspot)
Even with a ip release/renew still picks up 192.168
So that is my issue....
I can't think of anything else bar a factory reset which i'd rather not do just yet so thought i'd ask here first I geuinely searched everywhere!
any help would be much appreciated....
Don't mean to bump this but if anyone could offer any advice it would be much appreciated!
Even if someone could just confirm they are using the Orange/EE network with the Nexus 4 and has it working?
Thank you!!
i'm also on orange (EE).
bummer. mine's not working either. i thought it was but i think i was connecting to my router's wifi instead.
i also tried bluetooth tethering but couldn't get that working at all.
A sort of "me too", here: I'm also an Orange (EE) customer who can't get WiFi (or Bluetooth) tethering to work. However, USB tethering works fine - just appears to install a RNDIS virtual Ethernet adapter, and then just works.
Using Wireshark, I noticed that DNS lookups (which use the phone as a DNS server/ proxy) actually work. However, SYNs for connections to hosts on the Internet go unanswered. I'm beginning to suspect that the phone just isn't forwarding packets from the WiFi interface to the cell interface (but no idea why)
As a sort of aside: I'm pretty sure this used to work on my Motorola Atrix via Orange.
Having the exact same problem, running CM10.1.
Have messed around with APN settings but does nothing, laptop connects phone and even shows as having internet access but trying to visit any site just times out.
I have tried the exact same hotspot configuration with a giffgaff (O2) sim card and it works fine, so it must be Orange!
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.
Hello!
I have a bit of a weird situation here.
I have a WiFi router in a remote location that needs configuring (Linksys EA2750) as it lost its settings after a power outage. The person that could help me is technically challenged, but at least there is an Android phone there that I can access remotely. The phone is an un-rooted Nokia 5.1 Plus (still) running Android 9. This phone is connected both to the router via WiFi and to mobile data. I can remotely operate it via Team Viewer.
I have tried to use the router's official Android app, but it is unable to configure the router's WAN/Internet settings. I have tried to connect to the router's web admin page, but it is inaccesibile via the browsers (tried Chrome and Firefox). I have tried using a firewall app (Mobiwol and NoRoot Firewall) to limit the browsers to WiFi only without any luck.
The only thing that I think will work is to somehow force the browser to use the WiFi interface no matter what. I've already spent hours trying to find out how to do that, but I am kind of losing hope here. I am guessing that I might need root access to accomplish that, but I am hoping it will not come to that.
I would appreciate any help in making my friend's phone stay connected to Team Viewer's servers via mobile data and access the WiFi router's admin page simultaneously.
Thank you in advance!
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.
