I have wifi tether app installed but when I open and run it it constantly acts like it looses 3g connection. computer will connect with local access only. phone will have 3g logo and will switch between up and down arrows then have both then none then the 3g logo will dissapear. it acts like it is constantly switching between channel/signals but never stays connected. I am on a rooted 2.3.4 using downgrade and s-off running stock+ rom. I had wifi tether working in the past after root and rom but now it doesnt. my wife is on a rooted 2.2 with no issues. we have same settings and radios and hers works fine. I have used tb to uninstall and restore older versions I have uninstalled and downloaded the newest apk version I could find and it still does the same thing. The phone has no issues connecting to other wifi hotspots(home or public) and work fine on its own data for internet surfing. the only problem Im having is with wifi tether to connect laptop to.
radio is 2.15.00.07.28
software 4.08.605.2
any ideas or different free rooted apps?
running wifi_tether_v3_1-pre105.apk

Therr is a way to change settings in the epst menu which you access by dialing ##778#, that will allow you to use the stock hotspot app for free.

Dial ##778# and hit call. A menu should appear, select edit mode. A password box will appear enter six zero's (000000) as the password. A menu will appear select security. Look for and change any entries that look like "your#@dun.vzw3g.com" remove the "dun." so it looks like "your#@vzw3g.com". Then hit back to the main menu and select M.IP Default profile and look for and change the same entries as before. Once done hit menu and commit changes, the phone will reboot. Once rebooted use the stock app as normal ignoring the you must subscribe to this service message. Note if you do a *228 option 1, an ruu, or a factory reset from the settings menu or hboot, or have to reactivate the phone, you will have to edit the settings again before using the stock hotspot app. I have been doing it for years and verizion is none the wiser. There are either 2 or 3 entries which need to be edited.

Why is it not working? The menu isn't there? Are you on a stock rom?
if u r using an app, dont, could be the app itself having an issue, especially if your phone is not rooted, as most tether apps require root, try doing it through the settings directly and test it out, make sure u allow access to all devices (after you set a password for the AP that is), because if u select only allowed devices, you cannot connect even with a password
I just tried it with the stock app and it worked. It didnt at first, I entered the correct password I have chosen in win 7, told me limited access. The problem was coming from the type of security it wasnt the right one, in my case wpa2.

i have just rooted my phone ....
didn't custom the rom....
there a lot of choise in the setting , what i have to do to make it work fine..?
settings
->Wireless and network->More settings
->Network->Tethering and portable hotspot
->portable Wi-Fi hotspot ----> Activate swiping to the right --> Green showing
...it will show for 1s "Enable portable Wi-Fi hotspot..."
tap on Portable Wi-Fi hotspot
-->tap on configure on the bottom right corner
-->name your network SSID
-->choose the type of security you want (I recommend WPA2 PSK then choose a password, but you are free to keep it Open)
-->Save
... it will show enabling... for 1s
Finally you can search your hotspot from the device/computer you want to use it with. (be sure to right click on the network then properties to select the type of security the password is assimilated to)
Voila
i have the exact same problem...i can't make it working.. don't know why...in my case the other device can detect my phone and i already allowed the device mac address...the device is connected but to some point it cannot surfing the web.. my phone was also rooted and running stock rom

Go to Settings -> under wireless and network go to More Settings -> Tethering and Portable Hotspot -> click on Portable Wi-Fi hotspot -> Click on what is under the "Help" line, it should either say Allow all devices to connect or Only allowed Devices, if its set on the latter then switch it to Allow all devices to connect
This option doesn't mean that you access point is open to everyone, as it will only allow the devices that has the WPA2 PSK/password to use the AP, it just wont filter them based on mac address etc, give it a try, and see if that works for you.

Of course the US carriers will charge extra for this.
Thats what I figured, but there was no warnings whatsoever when turning on the hotspot about tethering fees..

Hi
I still have the PB : activate swipping right to ON is going back to off with message " non available data or SIM non valid"
Sim's OK double checked with carrier
Mobile data ON
So what's wrong?
Device GN2 Sgh-i317 AT&T, unlocked, rooted, stock Rom, using different carrier : not At&t
Hey All,
I just picked up my T-Mobile LG G3 last night and rooted it.
I am trying to use the tethering app like I did on the Nexus 5 but my other devices are not picking it up when I have it enabled on the new phone.
The app say's its enabled and shows the Name and passcode to join it, but again, no other devices that I was using before (ipad for example) see it when I scan for WiFi networks.
Can anyone please help? I use this app when at work and need to get it figured out and up and running again if possible.
Thank you,
Whiteice
Is the Wifi Tether Router app you're using by Fabio Grasso?
That's the one I was using on my Nexus 5 without any issues. I also just moved over to the Tmo G3 and can't seem to get any of my devices to pick up the SSID either. The developer says that it does work on the G3 and I also followed the settings laid out by the developer in his devices configuration page but still a no go. I emailed him to see if he may have some suggestions but no word yet. Hopefully he replies with something I/we can try to get this running. It was a great app on all my previous phones. I have faith in this developer, he seems to update his apps fairly regularly.

Yes that is the same app I'm using.
I contacted him and he replied back asking Me to send a log file from within the app. I Did that this morning and waiting For further feedback. If I hear anything I Will report back here.

I had the SAME problem with the app with my G3 and I've been back and forth with him via email. I had to try a few methods he gave me but the last one finally did the trick!
Here's his email that had the steps to get it to work below:
strange, yes other users use this app on G3
please try this config
Interface wlan0
Method 2
Channel 1
Encryption wpa2-psk
"No Firmware Reload" <- UNCHECKED

It works now, because the settings on his site and his emails weren't working, but the above finally did it for me.
But I noticed the the DNS process, /system/bin/dnsmasq, was using on average 40% of my CPU constantly with the app enabled. So I checked the "Use Internal DHCP" in the DHCP settings and the process ended and the CPU use returned to normal.
I had asked in a reply if this app uses IP Tables to mask the hotspot use as mobile use or still shows up as Hotspot with T-Mobile. I wasn't sure if enabling or disabling the Internal DHCP would negate it or not, but he hasn't responded back yet.
Does anyone know if this app does mask it as mobile and not hotspot?
I just came off of Sprint to T-Mobile two days ago and I always used the native hotspot function on my rooted Note 3 that masked it as mobile use.
Hope it works for you guys as well.

Darn, I wish it was working for me. I found that on Fabio's page and used those settings but they're still not working for me. Also tried to use the internal DHCP option but still no dice. I just sent Fabio my log file, hopefully he finds something that can get me up and running.
Woo hoo...I overlooked the method. Just confirmed the strings above works. Thanks all/Fabio!

I can confirm the above settings including the internal DHCP work perfect on my end also!
As a side note, it also appears that the data usage shows up on my T-Mo account as regular "Internet Access", not Hot Spot usage. Maybe I was looking at it wrong, or maybe my account hasn't fully updated yet, but it looks promising.
Thanks to JustLok for the tips!
Good to know it works. I tried it a few days ago and I didn't get any data, so I uninstalled it. Now that you guys confirm it's working, I might buy it.
I've been trying to get the stock tether to work. Found where to change the APN so that it doesn't use the pcweb one that tracks as hotspot, but I'm running into other issues, some other checks that need to be circumvented. This app is probably using the fast APN since pcweb is only listed deeply in the frameworks-res.apk of the G3 and those should never be used unless this app tries to tether as DUN (which I doubt).
Question, does this app have Tasker integration?
Just to clarify...'No firmware reload' should be checked or unchecked? Cheers!

It would be unchecked, as listed in my post above in regards to the settings and tweaks to get it to work with D851 G3.
Also, been using it for days now and it does mask the tether use as mobile data and NOT as Hotspot data, as orbitalcomp confirmed, even using the internal DHCP server (which I was wondering if it would with the IP Table masking).
As for Tasker integration, I'm not sure what you mean havanahjoe with Tasker, as in the normal App Tasker or an app titled tasker?
I also noticed that my data connection just dies every so often, both on my G3 and my wife's G3. It show a connection with LTE and the data arrow up lit, but no data is moving. Even confirmed with the Internet Speed Meter Lite app that no data was being sent or received. I have to enable Airplane mode and then back off and the data connections becomes live again. I've read several reports of this on XDA too on Tmo G3's. This is either with the tether app or not, Tmo's data connection just stops working and needs to disconnect and reconnect to the tower/antenna to work again.
Finally, when using the widget for this tether app, when first tapping it (after a reboot or so), it does not enable it. You have to wait a little and then tap it again for it to enable. Once you get it to enable and become active, turning it on or off via the widget works on the first tap. It's just the first initial widget use upon a reboot that it takes two taps, about 5 secs apart to actually start up.

Thanks for the update and confirmation of mobile vs. Hotspot..which meets my own experience. FWIW, your settings quote from Fabio simply says "No Firmware Reload" and doesn't state checked or unchecked...which is why I asked. At least I can't see it on Tapatalk. [emoji4]

The hiding of the traffic is all about the APN. WiFi Tether Router uses the phone APN (fast.t-mobile.com) and the built-in hotspot uses pcweb.tmobile.com. That's why it's so easy to bypass, as long as WiFi Tether Router can do its thing by doing some iptables, dnsmasq and other Linux magic.
I have seen my LTE connection stop working from time to time. Not while tethering, but I rarely tether for more than 30 minutes at a time. Whenever I lose data, I just do the same, airplane mode on/off and it's back.
Tasker is an automation app. It's great for getting things done automatically. I use tethering in the car so that my dash mounted Nexus 7 can get internet. With Tasker, my hotspot is automatically turned on when I get in the car, and automatically turned off when I turn the car off. There is a method for applications to talk to each other in Android, these messages are called intents. With intents you can tell an app to shut down, to load a specific playlist (Spotify for example), or to enable/disable something. When using the stock Tether app, the system lets you toggle it with intents that Tasker already knows about. WiFi Tether Router has no intents, so there is no way to externally tell it to turn the hotspot on or off. The workaround is to emulate touching the enable/disable button (on the app or the widget). It's kludgy, but it works. It would be much cleaner and reliable if the dev enabled this functionality.
I tried the setting you suggested on the other thread, and by using Internal DHCP and not having WiFi Tether Router use DNSMasq to provide DHCP and DNS services, my battery drain is much more acceptable. I only lost 3% on my drive to work. I usually would lose 10% or more! This setting might be needed for other carriers where you do need to hide your data, but we don't have to worry about this with T-Mo.

Thanks for that explanation on Tasker, when I mentioned it to my wife last night, she said she was already using it on her old HTC One M7, so much for me being ahead of the curve. Or on the curve even, I guess. :cyclops:
I have noticed when using the Wifi Tether App, sometimes my laptop won't or can't connect to the hotspot after a while using it. I use it for extended periods of time at work, hours on end even, and my laptop will just disconnect from my SSID and won't connect, despite it being live. The SSID is seen and the laptop tries to connect but then just says it cannot do so.
I need to reboot my laptop for it to connect to it again. I'm not sure if it's the IP lease on my laptop expired or wasn't renewed with the tether app. Unfortunately, I cannot perform an IP renew or release in CMD on my laptop, because it's disconnected and needs a connection to do it! So I can't narrow the error to that function or not.
When I use the native Hotspot with TMo, I didn't have this problem last week when I was using it for three days before getting the Tether app.
Just some experience with it so far, in case anyone else was seeing the same or so.
How the heck did you all get this app to work? I cant change my apn settings to ipv4 like he says too. Data cuts off when I do

This app is broken in g2/g3 lollipop. It will also break built in tmo hotspot app as well and you would have to factory reset to get it working again. I switch back to kitkat just to use this app and also see no benefit in lollipop.. yet..
Can someone please help?
I can't get any of my computers to show the network name for WiFi tether router. I've never had this issue until today. My wife's phones doesn't have a problem, but mine won't show at all
I just switched to unlimited data on my LG G3 and got this app...
It works great with the G3 settings shown on the first page of this thread and on the app website. The speeds are the same on the device as on a client device so that's good...very fast LTE.
I originally tried setting the APN to LP4 (from default LP6) as the application directions stated must be done for T-Mobile but found that the network slowed (4G instead of LTE) and became somewhat unreliable. I'm wondering if this is even necessary on the G3 based on what I'm reading here. I switched the APN back to default.
My plan includes 5GB of tethering with unlimited on board so the problem is that how can I tell which data I'm using? My account page only shows unlimited it doesn't show how much of that is used for tethering even when I used the native tether app. I suppose I just have to try and go over and see what happens?
I've got this working on Cloudy 2.5 but the data is being counted as Hotspot data. Other than the settings earlier in the thread is there anything else I need to change so that it doesn't get counted as Hot Spot data?
TIA!
Is anyone else having WiFi issues? Like my phone won't connect to public WiFi like at McDonald's or Kohl's or any place I open the WiFi settings pick their WiFi and right away it says 'failed to connect'. Even at my house it'll connect and after awhile nothing will load. Facebook, websites they just keep showing that their loading but never do. I have reboot to get it to work, and I'm on stock everything.

I'm having this part. Every now and then, especially when I leave my home wifi range for a bit then come back, the wifi will connect, but websites. email, etc will load forever and never get anywhere. I find that I don't need to reboot the phone entirely though. I just have to disable Wifi and then reenable it again. After that, everything will work correctly, but it's still not supposed to do this.
I have tried cycling the router's power several times, and it never fixes it. It's all phone related for me. Other than this though, everything else seems to work fine except for text messages occasionally taking forever to send (another issue for another thread).
I've tried rebooting the router but it does nothing. When things won't load on my phone my sisters phone works fine. Its just this phone.

Hmm, we could try some troubleshooting steps.
1.) Go to Setings>Networks>Wi-fi>Advanced Wifi
-Make sure "Internet unavailable" setting is unchecked under notifications then under "Useful Settings", try first to set "Keep Wi-fi on during sleep" to always, and leave unchecked "wifi signal weak" as well as "Allow Wi-fi scanning"
2.) You may want to change DNS settings of the phone
-Download a DNS changer app (set DNS, And DNS changer, Override DNS, etc). Next, try setting primary DNS to 8.8.8.8 and secondary DNS to 8.8.4.4 (Those are Google's public DNS)
3.) In terms of browser usage, you may want to observe on which browser (stock, or 3rd party such as chrome), does the issue occur more frequently. Then go to that browser's settings and do some re-configuration.
4.) If the problem is more evident when you connect to your home network, you may want to access your wireless router settings and change some settings such as the wifi channel, rts threshold, etc.
5.)By the way, what phone model are you using, and is it tied up with a carrier network?
