T-Mobile Note 4 [CM12]: Cannot ping when tethering. - T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting

Hello, I'm new here on XDA, even though I've been browsing the forums ever since whenever.
Anyway, I have a T-Mobile Note 4 running CM12 and I also must say that I do have unlimited data.
The problem that's been bugging me is this: when I was tethering on stock ROM, I could not ping any host from any of my tethered clients. However, pinging used to work on CM12 (indicating of course that stock ROM has restrictions imposed) until two days ago. I know this because when I tether to my PS3/XBox One, I can access the Internet but cannot login to PSN (Playstation Network). I can only log on to it when ping is working.
I do have an HTTP user agent spoofer for HTTP traffic but this problem seems to be more related with routing on the Note 4 I guess. I have tried many tethering apps (with or without root) in hopes that they would fix this problem but I still cannot ping.
I have seen on the Internet people mentioning native tethering and I was wondering if you guys can recommend any tethering apps that can fix this. Also, I'm not really familiar with the linux iptables and the routing utility and have been trying all these scripts I found on here but they are not working.
So, correct me if what I'm asking for is already done (which would then mean T-Mobile is blocking my outbound traffic on their routers), but what I was thinking was to route the wlan0 traffic straight through rmnet_data0 without any tethering flagging or something like that. Again, I do have internet I just can't access other services like ping which is needed by some programs that I have for MTU path discovery etc.
FoxFi/PdaNet - Not working
Wi-Fi Tether Router - Not working
Other generic tethering apps on PlayStore - Not Working
Thanks in advance.

Dears,
I just finished to setup my laptop to be an AccessPoint for my nexus.
I did this creating a new ad-hoc wireless connection.
It works! ...for browsing websites
does not work for market or app web connection...
I configured proxy settings to enable websites browsing.
If I try change proxy settings on my phone, obviously websites browsing stops.
Note I'm inside an office network now and I cannot change or control about network setups.
any idea why android market does not work with my setup?
does market need some "special ports" opened?
help me please....
Just download connectify. It's a program that makes your computer a WiFi hotspot. I use it to get internet on my x 10, and it works flawlessly
-------------------------------------

eh......
I already tried... bit my network card is not supported by connectify...
The same with VirtualRouter.
The only way I has some success is as described before (ad-hoc network).
Please help me with that market issue...
Could it be that it's blocked by your company? Like can you go to youtube on your pc?
Like i understand you are using proxy to connect the net so http is allowd and all the others are closed.
correct: proxy is only working for http access.
I have troubles also with google sync, gmail, youtube, market etc...
I'm only able to surf the web via browser.
Note that wih my notebook I have access to all youtube... so cannot understand why it works whit notebook but does not work with nexusOne...
maybe notebook and nexus use different protocols or services that are closed by the proxy.
Any idea to make my ad-hoc network fully open?
I'm having trouble getting connectify to work... it loads up and runs fine on my Win7 x64 laptop, but when I try to connect with the N1 it appears to be eternally stuck at the "Obtaining IP Address" stage before it finally times out and the network state is reported as "Unsuccessful". I've tried both pulling the IP from DHCP and manually specifying a static IP address on the correct network, and I have attempted running both Android 2.1 and 2.2.
Even when specifying a static IP, I still get the "Obtaining address..." status before it fails out.
Any thoughts?
for me too: both with ad-hoc connection, Connectify (@home) or VirtualRouter (@home) I have same issue than you.
Sometimes n1 connects the wireless network with no problems, other times it dont connect the network... Dont know the reason. Only I saw that if you delete the ad-hoc network and create a new one it works... It's boring, I know... but works..
also I saw that @home connecting in same mode than in office I was able to navigate market, youtube and all other programs that need an internet connection .
This to confirm that the problem I'm having @office is caused by some LAN restrictions (filters, firewalls and something like this)
Cool, I'll give that a go when I get off work I suppose. I've only got about another week or so here in Afghanistan, but while I'm here the only accessible internet is a wifi access point that passes through a fairly restrictive firewall/proxy before hitting the satellite internet. I'm able to bypass the firewall and proxy if I use an ethernet connection on my laptop (luck of the draw: my room in the tent is the one with all the networking gear ), and was hoping I could use this Connectify or VirtualRouter business to then extend that internet offering to my N1. So far, no luck. Maybe I'll fight with it some more tonight and get somewhere with it.
Off-topic: How's Padova this time of year? I spent about three months up in Aviano back at the end of last summer and fall... absolutely gorgeous country.
Maybe is useful for you to knwo ho I'm able to surf web using browser on my N1 (using win7).
3 modes:
- ad-hoc network (pc-to-n1) directly from network control center of win7
- connectify (using a virtual access point)
- virtual router (same as connectify)
@ home: LAN without filters or restrictions. I'm able to surf web, use youtube player, market etc.
@ work: LAN with filters and restrictions. I'm able to surf web only.
These are my tests. I hope you will have more luck than me.
OT: Padova is great in this period. Weather is hot (25-28°), summer is starting. Unfortunatly in these days we have some rain but our "sunny season" is already started.
I know Aviano, there's a US militay base. Are you a soldier? I'm a fan of the "soldiers world" (I played for a long time a free online game called "America's Army" )
Sorry for OT

Thanks for the info
And no, I'm not a soldier, but I work as a civilian geek/technician/engineer for a US defense contractor that builds air/battlespace control systems - like a glorified Air Traffic Control. I get sent for a few months at a time to different locations that we have our systems to support the soldiers and airmen who use them.
Needless to say, Aviano has been the best assignment yet

If you can use everything @home this isn't a fault of your setup. everything gets blocked by the proxy server. if you really want it you have to talk with the administrator, i really doubt that he will do changes to please you.
for now i think it's impossible to use them.
ok... thanks for the bad news...

I have the same problem (ok, with a Desire). No IP obtained. OS is Win7/64 too.
Did you have any success in the meantime?
I think the market actually uses https:// ... is that set up as well? Even if it is, the phone might reject it because of redirecting certificate issues...
You're probably better off setting up a VPN on your home machine, or some server outside the network. Then VPN to that on your phone for open access (Of course u can buy vpn accounts from various companies too.)
What kind of proxy is it? Socks? http? remember most don't support UDP, and may only support port http or https.
How do you get N1 to see ad-hoc wifi? I tried but wasn't able to using stock froyo...
Heeeeeeeeeelp please!!!
i have installed connectify and the virtual router on my win7 laptop.
i can connect to the new wireless networks created by these softwares but I can't browse the web (no data is received in my Nexus one)
can you please help me?
I have stock froyo FRF91 on my Nexus one

[Q] VPN issues

Hi All,
I am having issues when trying to connect to my work VPN. I need VPN access in order to check my work email and browse an internal website.
Now, the VPN always connects, either on 3G (in UK) and wifi.
However, even if it says "connected", I am not able to download emails orbrowse the intranet unless when connected to my home wifi and sometimes on mobile internet.
If connected through other wifi networks (recently tried on a hotel free wifi, in the states and on a private home network, in Croatia), the connection itself seems to go through some sort of bottleneck, and no emails or browsing is then available.
I am blaming the phone itself, since my colleague had no problems whatsoever on his iPhone.
I am on Galaxy Note, non rooted, Vodafone UK.
Please help, this issue is making my Galaxy Note almost useless.

just FYI I'm also on UK Vodafone and I can connect fine with openVPN to my home network ... tested on 2G,3G/H+ and also on various public & private WiFi networks - always connects fine, only issue I have is that my server .ovpn tells the phone to use my home router as it's default gateway (so that I can browse securely on public wifi). This doesn't work out of the box - I need to use the openVPN app's "fix DNS" option.

errr ... I'm an android noob, but AFAIK you need root for openVPN to work? I never tried running openVPN on my note BEFORE I rooted it, but anything I've ever read says root is required?

What APN do you use?
I have to switch everytime to something called MyLan to connect over 3G.
I am using the stock VPN client, did not adventure myself into OpenVPN. Would that work with an encrypted VPN?
Ah, sorry - I somehow managed to read the thread title "[Q] VPN issues" as "OpenVPN issues" .. case of my eyes seeing what they wanted to rather than than what was actually there. You are of course right, the stock VPN options don't need root (and of course openVPN client will only work to talk to an openVPN server).
I did set up a PPTP server on my WinXP home machine and tested that with the note's inbuilt PPTP VPN client - it worked OK although I needed to turn off encryption, and I didn't do anything with it beyond just connecting as I was only dong it out of interest.
re. the APN - I don't actually know where to see that on the note (noob, as I said!) - when I do settings->wireless & network-> mobile networks, which claims to allow setting APN's, there is no info or settings re. the APN other than the "network mode" and "network operators" items, neither of which seem to show the APN used for vodafone data access.
Anyway, sorry for the bum steer, hope you get it sorted

Oh, never mind
Under mobile networks you have to go under Access Point Names, but most likely you will only have one APN, which is the regular from Vodafone.
So most likely is the encryption causing problems?
D'oh ... I thought that was a heading, didn't realise it was a clickable item! my APN is wap.vodafone.co.uk (APN type is "internet+mms").
IDK if encryption is anything to do with your issues ... I doubt it if you can consistantly connect from home wifi and sometimes from 3G - if encryption were the problem I'd imagine it would consistantly connect (or not) rather than be variable.
Maybe worth trying to ping your internal mail/intranet servers when connected and then talking to your work IT guys in case there are firewall/routing settings that you are somehow falling foul of?
Yes we are doing that, however that fact that iPhones can connect really makes me wonder!
Thread Moved To Q&A​
This is a question, and as such belongs in the Q&A Section​
there are lots of third party vpn tools and free available you can use those
Wilsonj,
Can you please suggest one third party vpn tools that works well on PPTP, with encryption?
I am not looking at OpenVPN, since it doesn't suit my needs.
Thanks!

How I got tethering to work (3 different type of methods)

Hey all, I been reading all kinds of methods to tether with the Nexus 5 (also during the Nexus 4 prime), and helped a couple of members here at XDA how I got to tether my T-Mobile's truly unlimited data with 5 GB sharing (it used to be 500, then 2.5GB, now 5GB) connection to my PS3, PC, and other smartphones. Many have PM'd me to explain it further for them how to get it to work, and I figured "I should just make a thread on how I got it to work". In this thread, I will explain to you how I got tethering to work on my phone using T-Mobile's service (it might work for At&T and other carriers). I will tell you the three apps I use and the pros and cons of each app when it comes to tethering a specific device.
Please note:I am not responsible for any consequences you will face with your carrier using my method, nor will I be held responsible if you use my method without having a sharing data plan. This method is for use of a sharing plan that YOU pay for. If you decide to use this method without having a sharing plan, then do what you want, it's your plan, and your money. I have spent a lot of time doing trial and error in order for my tethering to work 100%. I even went over my 5GB of sharing data and I still was able to tether. I think I know why, read the last paragraph of this post. Again, THIS IS FOR MEMBERS WHO PAID FOR TETHERING SERVICE.
Without further ado, you will first need to edit a database located in /data/data/com.android.providers.settings/databases/settings.db. You need to add a new entry that is called "tether_dun_required" with a value of 0. Google and T-Mobile decided to team up and provide a way for T-Mobile to sniff what devices you are tethering to, thus sometimes redirecting you to the T-Mobile page saying you need to add a sharing plan. You can either edit the database with a sqlite app/program, or simply install the install zip (thanks to yakman66). There is an uninstaller if you wish to revert back. I have no idea if you should reflash the zip after you install a new ROM or update it, but I did it anyway. If you need a deeper explanation, refer to the first 4 posts from this thread here:http://forum.xda-developers.com/google-nexus-5/general/fix-nexus-5-tethering-block-t2581035
Installer:https://github.com/marcandrews/hammerhead-hotspot-fix/releases/tag/v1.0
Uninstaller:https://github.com/marcandrews/hammerhead-hotspot-fix/releases/tag/v1.0u
Now we get to the apps. The three apps I use to tether are PDANET+/Foxfi, Clockworkmod Tether, and WiFi Tether Router
PDANET+/Foxfi: Note: There is a free version of PDANET/FOXFI, but you will be kicked off the tethered connection every 20-30 minutes,and I believe there is an a limit of how much MB you share daily. Purchasing the app is only $7.97.
Download from Play Store. Link:PDANET Foxfi:Foxfi Foxfi for At&T and Sprint:Foxfi (Sprint/AT&T Only)
Please make sure you download the correct Foxfi for you carrier. PDANET is for connecting via USB and Foxfi is for bluetooth and wireless. You must install the PC program located here. This app is pretty much self-explanatory. You just set up the network name and password if you decide to use wireless, or plug your phone in PC via USB with PDANET+ for Windows installed.
Pros:
No need to root.
Tethering for your computer: Pretty much instant. Easy setup. Just to be safe install a user switch agent and change it to IE 7.
Tethering for gaming: Using my PS3, I am able to play online with my friends. I am running around 30-40 ms ping, which is not bad for wireless. Smooth.
Tethering for other smartphones and tablets: Easy setup also.
Cons:
You have to pay the app in order to use the app for its full potential.
Computer: For some reason, I get kicked off for a couple seconds from my tethered connection and then connected again. I even enable "Hide Tether Usage" on the options with Google DNS checked on the settings. I think because T-Mobile blacklisted Google DNS (idk?)
Gaming: Your NAT type will never be opened. That means if you join a party that also does not have an open NAT, expect not to be able to join that person. If anyone knows a way to port forward your carriers IP address, please let me know.
Smartphones and tablets: Haven't experienced nothing wrong.
WiFi Tether Router:
Download: WiFi Tether Router
Configure your Network Name SSID, encryption type (whatever works best for you, I use wpa2-psk)m WiFi password, and then enable the tether.
Pros:
Much cheaper than PDA/FOXFI. Only $2.50
There are more setups you can do for this app. You can change the interface, method, drivers, WiFi Mode. There are also tweaks especially for consoles like MTU adjust, enabling DMZ, DMZ Port Forwarding, and DCHP settings. Perhaps you can port forward and have your Nat open with this app, but I'm not expert when it comes to these, perhaps someone out there can find a solution? Let us know!
Computer: Haven't tested it to be honest. If someone is willing to try please let us know how it went.
Gaming: Easy setup. Works just as good as Foxfi
Smartphones and tablets: Works just as good as Foxfi
Cons:
You can only use wireless, there is no USB.
Gaming: Same as Foxfi, Nat is not open.
Smartphones and tablets: None.
Clockworkmod Tether:
Download from Play Store: Clockworkmod Tether (no root)
After that install the drivers of your phone located here
Last but not least, install the tether software on your computer.
Mac: http://download.clockworkmod.com/tether/tether-mac.zip
Linux: http://download.clockworkmod.com/tether/tether-linux.tgz
Windows: http://download.clockworkmod.com/tether/TetherWindowsSetup.msi
Once installed, allow debugging on your phone to PC via usb and start the tether connection.
Pros:
Free, you just need root.
Computers: I don't get kicked out whatsoever tethering on my PC. Not once did I get disconnected for a second and reconnected. Like I said as a precaution switch user agent to IE7.
Cons:
Gaming: Won't accept USB.
Smartphone and tablets: it only uses USB tethering.
So there you go guys, these are the apps I use to tether my devices. You can choose whatever works best for you. When it comes to me playing online or sharing my net to smartphones and tablets, I use Foxfi because it is simple to set up. WiFi Tether Router I just use it as a backup. When it comes to tethering my PC, I use clockworkmod tether because I don't get disconnected from my computer.
I have been using these apps since Nexus 4 and not one time I got temporarily banned from sharing my net. Well actually I did, but it was the first time I ever tried it. Ever since then, I was able to use my tethering to its full potential.I use my data to play online (my home net sucks), and I have not been flagged. Playing online does not consume a lot of data (about 20-30 mb an hour).Here are a couple of ways to keep using your tether without being flagged by your carrier.
1. DO NOT DOWNLOAD BIG FILES ON YOUR GAME CONSOLES. Guys, please use your home internet to update your console version or downloading a patch. As soon as you download a file on your console you will be flagged. I have not tried it with the new 5GB sharing limit but I have tried it on 2.5 and I immediately got flagged, even though I was not close to my sharing limit.
2. Don't download torrents or pronz on your PC using your data. If you want to do that, I suggest going on your phone and downloading it via your phones browser or torrent app. This way your carrier will know you are downloading straight from your phone and not from a tethered device.
Other than that, use your tether how ever you like, but with responsibility. Tethering to other smartphones and tablets seem to not red flag T-Mobile at all. I shared 10gb of data to my coworkers and all they do is stream Pandora and YouTube. I hope this will clear things up and hopefully there will be better alternatives, but I think these methods should let you use your tethering service.
Sort of confused here, I use the built in WiFi tethering in my non rooted nexus 5 on T-Mobile without issue. Why does one need this?

Wait, what?
I've never had an issue using native tethering in stock Android on my Nexus 5.
So, are you saying enabling Tethering & Hotspot in the Settings menu doesn't work for you, and apparently many others?
I use built in tethering with the hot spot fix. No redirects to T-Mobile.

You got tethering too work despite your network, you mean? The n5 tethers wireless, bluetooth, wired, perfectly. The restrictions of your data plan or network are another thing that is nothing to do with an unlocked n5

[Q] Tethering without my carrier knowing

I have a Samsung Ativ S which I have been using as a WiFi hotspot to connect my laptop and Nexus 7 to while I am working away. Recently got a text to tell me if I carry on I will be cut off on my mobile contract. I have a sim only deal that gives me unlimited calls, text and 3G internet so I'm a bit brassed off. It took an hour of searching to find the no teathering in the conditions of use.
Any way what I want to know are there any Windows Phone apps that will hide the teathering from my supplier? I am hung off a T Mobile/ Orange network.
Daedalus1
ATIV S can use wired tethering (search the forum for it, I posted instructions and drivers sometime last year). Even though my plan supports tethering, it's data-limited and when I use the wired tethering they don't list the data usage for it so I'm guessing it's not detectable, or at least not easily.
There's also an app called TetherX or something like that, which will act as a SOCKS proxy server on the phone; you then set your PC to use the phone as its proxy server. Won't work for non-proxy-aware apps but otherwise should do the trick.
Of course, this all assumes they're checking whether or not you're using the phone's tethering feature somehow, rather than doing something more nefarious like deep packet inspection. If they're checking "are you using the 'Internet Sharing' feature?" then I would expect them to just limit its usage; the phone has the capability to test whether or not tethering is permitted on your plan, and does so test by default. If they're using DPI and noticing traffic to/from PC clients (based on user-agent strings or something) then you're in trouble unless you can route all your traffic over SSL, which mostly thwarts packet inspection.

Tethering PS4 through VPN...and Tmobile still knows!?

Hello Everyone.
I am using a VPN and the Wifi Tether Router paid app from the market. I am curious as to how T-mobile still knows I am tethering, as I just got a "You used 80% of your High speed data" text from them (Have unlimited data plan)
Any ideas on how to completely hide? SSL? Proxy? Only seem to have issues with the Playstation and not the PC....
Any help appreciated...
The PS4 data probably shows up different on the network than PC data. I've read that T-Mobile put some new things in place on their end to identify data usage being masked.
Sent from my LG-H811 using XDA Free mobile app
I saw similar results. I noticed that when I tether, it doesn't route me through my openVPN connection regardless of the tethering method I use. You can test this on your own, fire up the vpn, then tether to your PC, then go check the external IP on your PC.
You'll most likely need a non-stock ROM for it to work. The ROM probably reports all MACs and the traffic passing through it to T-MO.
