I want the application I am developing to use the Wi-Fi and Mobile Data (cellular) interfaces simultaneously on my Android 11 Galaxy Tab S7 5G device. The setting "Mobile data always active" does indeed allow fast interface-changeover. However, both interfaces are never data-accessible simultaneously. Using a third-party channel-bonding VPN service, called Speedify, this is possible on this Galaxy Tab S7 5G tablet. Speedify uses something mysterious called channel bonding with their VPN service to accomplish this. Also, a Google Pixel running Android 11 is also able to use both interfaces simultaneously, without any third-party utility help. In addition, the Garmin ActiveCaptain App also, somehow, gives this tablet the ability to communicate on both interfaces, simultaneously. How can my application use both interfaces on a Galaxy Tab S7 5G without using the Speedify App (not possible because of security and business reasons)?
Did you get anywhere with this?
How have you verified the Garmin app has this functionality? And when are both interfaces used? I wonder if only one channel has a typical data connection, and the other is for some other purpose (location, or something).
I think Speedify gets around the usual OS limitations by creating a single virtual device that all requests go through, then they decide which network to send packets on. It is neat to hear this can work on a mobile device though! I had assumed their service was for people on more typical PC like hardware.
In a way I'm not surprised Google's own phone has managed some tricks others haven't. Though I'd hope it wasn't an Android 11 only feature (meaning 12+ don't/won't have it).
This assumption of only cell or wifi being active might be baked in at an OS level to force better battery life. Personally I like flexibility and choice, but I can imagine less knowledgeable users getting angry at their terrible battery life (after they enable a feature they don't understand).
Maybe this is worth filing a bug with Android and seeing what they say? Or asking Samsung directly?
I was bummed when I figured out I couldn't just pay two ISP's for internet service and load balance across both easily. That my consumer router's optional 2nd WAN port was only a failover option (use one or the other).
As you alluded, for Samsung phones and tablets running Android 11 or Android 12, the ultimate solution is to route both WiFi and Mobile Data (cellular) data through a virtual interface e.g. tun0, via a VPN tunnel interface. I believe this will "shield" the Samsung one-or-the other route-switching that prevents simultaneous operation over both WiFi and Mobile Data. I am assembling just such a VPN now. I could certainly use any tips or suggestions from others that have already been down this road.

I have been looking for an application which is a more powerful version of the WiFi Tethering already included in a phone.
I have been looking for an application on Xda, Google, and the Marketplace but none I have found provides me with the ability to see individual users (or Mac addresses) data usage.
First a little background on what I am trying to achieve.
I regularly provide a WiFi router for people with IPods and devices with wireless but no internet connection who need internet access to update games / browse the internet, and whilst my FUP at 500mb is quite low, I rarely use more than 20mb in a month so it doesn't bother me as beyond 500mb the connection is just limited to text and images (downloads and internet streaming are disabled after 500mb) which is all that I need.
However when my FUP has been exceeded alot of devices cant do the small updates this is no good when games or apps require it (as I have seen a couple even stop working till updates are completed) due to the connection being restricted. I have usually tracked it down to an over enthusiastic user who is watching videos on youtube, which has wiped out 100mb of my usage within 2 minutes on one occasion.
I am running both Android and Windows Mobile on my HD2, however I doubt WM will have a suitable app which is why I am hedging my bet with the Android market place, however a Windows Mobile version wouldnt go without great thanks, Whilst the built in "Portable Hotspot" of Android is good as it lets me restrict the number of users and see the Mac address of connected clients, it doesnt let me monitor their usage and then let me disconnect individual users them from the connection.
Whilst im sure there is apps for overall phone usage I am looking to monitor the individual devices usage as with 3-5 devices it is hard to distinct between legitimate usage and constant heavy usage.
Is there any Wifi Tethering app to let me do this?
To summarise:
Wifi Tethering App
Android / Windows Mobile
Shows Client Usage
MAC filtering (or alternatives which allow individual devices to be disconnected)
Preferably freeware however im sure I could be persuaded otherwise.
Thanks in advance
I was also thinking an app like this would be useful.
I can keep track of all data with 3G Watchdog, but knowing exactly how much data each wifi connected user takes up would be nice.
I realize this is thread necromancy, but did you ever find such an app? I too share my unlimited connection with coworkers, and there is one in particular that likes updating Xilinx (a "patch" is 8GB) and Windows Updates and so on over my connection. I am looking for something with QoS so I can put bandwidth caps on the heavy users that aren't my 4 machines.
Bandwidth ruler
There is an app called " bandwidth ruler free " for this . But this app monitors all users data connected to the Wifi hotspot . So it gives the overall data usage.
It can also set the download/upload speed for the wifi hotspot and this applicable for all the users .
it can also create multiple simultaneous data plans for the wifi hotspot.
you can download it via this link :
Also , you can find its description in the following xda thread :

Hey guys,
I was wondering if there was any app in development that let me use my phone as a real Walkie Talkie.
What I mean is, instead of using my network connection or accessing an external access point, is the any app that lets me use the wifi module in my phone, connect to another phone and transmit audio data between the phones?
I'll make it simple.
> Say I am part of a major event where my buddies and I using cameras to record from different angles.
>Instead of using Walkie Talkies to contact each other, can we turn on an app that lets uses my wifi module to connect to his module and relay voice messages between both the phones?
Services like Tickl are dependent on the strength of the ISP. I am looking for an app that allows me to create a secure connection based on the hardware already present on the phone.
If I can use my phone to connect to the internet, and in fact use it to create a Wifi Hotspot, why cant I use it to do something measly as say call for free in a large room or any event where it isn't feasible to shout?
http://www.crocko.com/903E0046F8BC4EC796E0A3A033C82DC7/Intercom_1.0.rar
it is for real walkie no internet but need hardware.
Craig's Walky Talky!
ok, this does not use voip, no servers, no Internet required!
It has 2 modes
1st mode (default on run) it simply uses your wifi modem to relay your voice data, so everyone using the app on the same wifi network can hear each other!
2nd mode "enable ap" this turns your phone into a wifi router, once enabled on 1 device.. on the other android device click wifi and scan for the ap from the first device..
This mode allows you to talk out in the open anywhere anyplace using just 2 or more android devices just like a real walky talky!
https://play.google.com/store/apps/details?id=com.walkytalky.craigs.walkytalky
you have a range issue with relying on a wifi chip only.
google : " smart your walkie talkie "
Range issues with wifi chip?
Well yes... it's a mobile phone, not a walky talky!

Look for PMR - Walkie Talkie WiFi on Google Play . I used it on my 2 phones: Galaxy S1 and A5. This app uses WiFi connection.
You can talk to one or many persons. Range 100-150 meters, probably depends on phone.
Zello works great. It runs on internet or Wifi all you have to do is download and make an account then find each other by user name. You can make a group channel with multiple contacts or talk individually.
I have a grandfathered Unlimited Verizon Data Plan that my company is paying me to have. I do not like Verizon, and am out of contract, so I recently purchased a Nexus 5 and plan on paying monthly with Ting. I have to maintain a "company phone" but using Google Voice, and importing all my accounts, it is really trivial that I would be using the Nexus 5 on a different carrier, since they only subsidize their employees, the device does not actually belong to them.
Instead of leaving my GS3 in a shoe box somewhere or selling it, I wanted to try using it as a dedicated hotspot for my apartment since I live in an area that has capped data from ISP's and no real solution (read FIOS) yet.
I purchased a Netgear Wireless Bridge Adapter WNCE2001 and set it up to connect to the phone's wifi hotspot and plugged that into the WAN "internet" port of my router running Tomato 1.28 firmware.
All seemed ok as far as ability to surf the web, use netflix from my TV, etc however there was a huge problem with some of the things I host from my internal network, such as media servers Subsonic, and Plex.
I am not able to access anything hosted on my internal network from any external network, even though I have not touched or altered my configurations - just replaced the WAN / "internet" port of my router with the tethered data connection.
After days of research and reading I have attempted a few fixes, although none have truly worked so far:
1) I tried connecting the phone to an open VPN server and then routing that traffic through the built in wifi tethering . This indeed worked - I followed some threads linked below, and was able to verify that now everything on my network was using the Open VPN connection - however I could not figure out a way to forward the ports appropriately and access Subsonic or Plex from the outside world.
http://forum.xda-developers.com/showthread.php?t=1993689
http://forum.xda-developers.com/showthread.php?t=2317841
2) I attempted using SSH tunnel from a remote Linux Server and although I could verify tha the tunnel was getting data piped through, I could not actually access Subsonic or PLex from the outside world. I tried to use tsocks to force all traffic for each service to use an established SSH tunnel but did not have much success.
It is important to note that these methods were tested on a shared server of a friend of mines, as far as I know they do not have root access and can not alter the open VPN or Open SSH configs or manually open ports on the server side. I wanted to just test it out to verify that it could work because I do not have a dedi or vps at the moment, I would consider getting something small from digital ocean or Amazon EC2 if this could actually work.
3) Lastly, I tried to use this port forwarding app, which as far as I can tell did absolutely nothing
Any help or direction is much appreciated, at this point I am more frustrated because after hours of reading and trying things out I feel as though I am now even more confused as to why this isn't / can't / could be working?!?!
Another thread I found here that seems like maybe it could be similar is the ability of getting NAT free with XBL using tethered data. I dont play video games, but I am wondering if something similar could be done using a crossover cable to allow for opening up ports through the wireless ISP as well? The older computer I use to host my media stuff from is running Ubuntu, and I have a Macbook Laptop, I only run Win7/8 in VM's on occasion - ideally though I want to find a solution that only uses the Linux Laptop, the phone, and the router - I can't leave my laptop home.
TLDR;
Halp! :silly:

How to I send media servers from one side to the other and avoid all the NATing and dynamic IP's ? :victory:
I use versavpn with verizon and connect with openvpn. They give 3 ports to forword and dedicated ip. You chose the ports u want to forward on there web site. I have plex and remote desktop and a ftp server running on my unlimited data Verizon plan 300 gigs used a month for 3 years now. This has worked OK for me. I also ditched the tethered phone and went for a 4glte router instead much less hassle.

I was trolling thru the settings and saw there's a built in VPN that can be used is it worth it or is this one that Verizon has control over and would just hand over your info to the mafiaa anyway ? Anyone know more about this or have you used it yet ?
It's just a remote access client. Stock Android comes with one, which you can still use here, LG has provided a more advanced one that has better compatibility with more advanced forms of IPSec encryption, haven't really played with it to see what else it does.
I highly doubt that Verizon has instructed LG to intentionally compromise the security of their VPN client, the legal ramifications alone would make this a very foolish decision, even for Big Red. The security of the traffic sent over the tunnel depends on what type of encryption was used, and we can't currently be positive that there is a type of encryption out there the NSA can't crack, they don't need Verizon's help to do so.
What type of VPN are you trying to connect to? If this is corporate or educational the security of the traffic isn't your responsibility anyway.
I just use the stock Android on. I have been using it for years so I stuck with it. I played with the LG one but for what I need, the stock is all I need. I use it to stream movies to me phone from my home server and I can access my drives.
Sent from my VZW LG G3 (tapatalk)
I never used it before and all I would need it for would be the occasional stream when Netflix don't have something. So I guess the LG one would work just fine. I didn't know much about there VPN being on he in the first place or android. So thanx I leaned a bit tonight. ?
And ya I know all about if the nsa wants you they'll get you lol. Which is why I won't even step near anything like Expendables. Lions gate is like a pack of wild dogs going after people right now. ?
Given the actions of our Broadband and Cellular companies over the last few years, i have decided i wont use my computer and phone without a VPN. They have no right snooping.
I use VYPRVPN and i have tried many Vpn services over the last 2 years. VyprVpn seems to be the best bang for the Buck and the have the fastest speeds and a large amount of servers. Two things that separate Vypr from all the other VPN services is they use their own proprietary Protocol called Chameleon Protocol which is built on top of OpenVPN. It adds another 256bit layer of encryption on top of OpenVpns 256bit encryption and keeps our ISP's from knowing if were are using a VPN at all. The other added Benefit is they use their own DNS servers and detect and prevent DNS leakage also built in kill switches for in case you loose your VPN connection for what ever reason it will disable your internet all together to keep whatever you were working on from leaking out for prying eyes. They do minimal logging. They would prefer you not to do any torrenting but they dont block you from torrenting. But if you are someone who likes to torrent then use a server outside the US that doesn't have strict piracy laws.
Like i said i have used many VPN services and VyprVPN is by far the best ive ever used. There are tons of perks that others cant come close to offering. I have the premier plan and its worth it.
YES VPN IS WORTH IT. Anonymity is a must for me and should be for everyone else. What i do with my connection is none of anyone else's business. Especially since i pay a buttload of money to have internet. Hope that helps.

My ISP (Sonic.net) allows VPN if you have a valid account.
The LG VPN works fine. Still getting LTE speeds through their backbone.
I guess I'll keep VPN enable permanently.
Sounds good. Now to learn how to use it properly lol. But ya my thoughts exactly no one needs to see what I have on my connection but me. And with all the snooping going on and intrusive adds grabbing info to see what sites you visit just to send you relevant adds (cough cough ) it's a great idea.
Most routers support VPN so its free to setup and easy to do

Hi all. Trying to get the lg VPN going but I've only ever set one up for my home comps n they basica9did everything for you. One click setup so to speak.
I got to name the VPN then it asks for the ip address but is that my ip or the one I want it to show (masked) ?gotta admit I don't know much bout this lol thanx in advance guys .
VPN on Android
VPN on Android has kind of been a sore subject since KitKat. I used to connect to L2TP on Mac OS X Server (snow leopard) from my phones as far back as Gingerbread, but with KitKat, L2TP became incompatible with Apple's implementation. That being said, PPTP works fine although being slightly less secure than L2TP. Android connects just fine to my Ubuntu Server PPTP, but no matter what I do I can not get get OpenSwan (Linux L2TP) to work outside my local LAN. Considering I have the EXACT same problem with OS X L2TP over the Internet but iOS devices can still manage to "phone home" to my L2TP server, I'm sure has something to do with my ISP considering L2TP an "enterprise" application and blocking my traffic, but iOS devices use some form of non-standard/undocumented L2TP.
I use VPN all the time for the simple fact that it provides a secure tunnel back home so I can grab files off my server, etc. Not only that, but it's a good way to provide at least some security when using public wifi. The thought of using public wifi without VPN gives me chills. It is disappointing that Android has deemed PPTP not secure enough to enable "always on vpn", which would tunnel 100% of your data through your VPN whenever a data connection (4G or WiFi) are available.
Hi there,
I am building a home router on some decent pc hardware. I do this only to have a router with enough power to support decent encrypted vpn connections.
What I need to know is the following.
Is there a way to let an android device connect to WiFi -only- if the vpn is working?
This is tricky I guess. There has to be a WiFi connection otherwise the device cannot contact a vpn server.
But the point is that I don't want my users (wife and to lovely boys aging three and five) to connect to the Internet (via wifi) without any decent encryption.
I don't want to use a vpn service. I do this at home with the power router I build.
If I must pay for an app that does this than please suggest that. I love to pay for a good app that does what I want.
Any thoughts or suggestions?
Many thanks,
Sebastiaan.
You could use Tasker to kill their mobile data at home (depending on the phone, ROM, root, etc,) and then if the *only* Wi-Fi hotspots configured on the phones are the VPN-enabled ones, then you should be fine.
At my house, I use an Asus router with VPN Fusion. I set up my Surfshark once in the core, and my entire mesh has VPN. I just go to a page to tag each device, or set default to whatever VPN I want. Some of them go to another site I use in a different state, and some use Surfshark. If my mobile data was off, I'd be totally disconnected from the evils of the internet.
Also recommend using something like Blokada, and ensure you have always-on VPN set to either that, or another service. You can definitely set it so Android pulls that up on boot. That being said, in the case of rebooting the phone away from home, I'd imagine there's some period of time that the stuff on your device could hit the regular internet. That's where something like Blokada comes in handy. I use it to block as many google servers as I can, while still having some of those apps still work to some degree.
Depending how crazy you want to get with this, you could set a static DNS on the phone that only works when the VPN tunnel is established. There are many ways to skin this cat.
