WiFi/mobile data problems - AT&T LG G3

The issue I'm having is that my WiFi and mobile network both show that they are connected, but I don't actually have working internet. Even weirder is that when I first flashed the rom (OctOS MM), I could connect to and use WiFi and data. Chrome, Play Music, Facebook, etc. all won't connect even though it shows I'm connected to WiFi and/or mobile network. I know I read something about the same type of issue but of course I can't find it now. Looking for some help, I don't know what to try to do to fix it.

For mobile data did you set the correct apns?

Yep, also looked in WiFi settings but didn't find anything out of the ordinary there either.
Any reason data and WiFi would've worked initially then decided to quit?

Strange data connection problem

I didn't have any issue since this week but this week when I'm on wifi I can connect to all websites but when I'm on 3g I can't connect to some of them. And my applications which collect data from those websites also can't receive any data (eg. like some local forum or traffic apps). When I switch to wifi everything works. Any ideas? btw I'm on insertcoin 2.2.5 SSE. But I tried other roms and the result is the same.

Sounds like this could be carrier related. Did you have this problem when you were on stock ROM?
Also, try using the phone as wifi hotspot and see if you can connect to those sites on a laptop using the hotspot.

[Q] Browsers won't work while on wifi

I noticed before that a bunch of my widgets would only work while on data and not wifi, i ended up switching to other widgets that would work with wifi since I use that more often than data. I dont use the browser very often or i would have noticed this earlier, but browsers dont connect when on wifi. this is on stock and dolphin and they both work fine when on data so its definitely a wifi thing. Apps connect fine while on wifi, so its not that my wifi is messed up. Anyone else have this problem? Know a solution? Im at a loss, dont see why thered be a difference between data and wifi, both r internet connections.

Not sure if its the problem, but check Settings > Wireless & networks > Wi-Fi settings > Advanced > Proxy and make sure it's empty.

Similar loss of data.
I am having problems with data and the problem seems to be built in to the software I'm running. (I am a bit of a noob) went from xda to http://www.toms-world.org/android/index.html and installed the recommended ROM and Kernal (tweakstock 1.4 and PBJ). Had no problems and like it all BUT, if I turn on wifi it turns of data. The button looks like data is on according to my settings but the 4G/3G symbol disappears from the info bar. I can't use any service that requires the data connection. When I turn off wifi, data goes back to normal.
I tried the above suggestion clearing out the proxy but it didn't change anything.
btw, I am terrible on these forums. I swear I do search and search and try and find answers before I ask. I think I am really bad at using the search function. I am guessing that maybe there is an option for this built into the ROM or something but I can't find it discussed anywhere

2 things:
1) The disappearing 3g/4g icon is normal, happens on stock.
2) Check Settings - wireless & networks - wifi settings - advanced - proxy and make sure it's blank.
EDIT: I'm an ass. Missed the part where you said you did 2) - hopefully imnuts was more helpful on this one
Also make sure you have nothing in for static IP settings, or DNS settings.
This is sorta on the same topic, the removing all proxy info worked to get most things working on wifi and data except mms. if i get an mms it will not download unless i am on data. Anyone know if this is a normal thing or does something need to be turned on, or off? thanks

That is normal as MMS requires VZW's DNS server, and odds are, your wifi connection won't be able to get it.
I have the same problem but only at my work on a public wifi connection. My wifi works great at home but everytime I try to connect at work my browser crashes. I checked the proxy and it says none. Im running jelly bean on a galaxy nexus.

[Q] [HELP] G2x Wi-fi Issues

I'm at the public library and the wi-fi on my g2x says its connected but there is no internet. The signal's excellent but no internet connection whatsoever. I have tried battery pull & reboot but that doesn't do anything. Also forgot the network, turn off wifi, and reboot, but it doesnt work out either. Can anyone show me the steps on how to resolve thanks.
Step 1: disconnect from library wifi
Step 2: connect to reliable wifi

Well for one, are you sure that wifi offers internet access? Not every wifi has internet available to it. Next, how are you testing for internet? Some free wifi require you to open a browser and read a agreement of some sort before it allows you through. In that case just connecting then launching tapatalk would show as no internet, even if there is. Being a library wifi I imagine you need to log in first via browser.

I've had this same problem before. If you can rule out options like battery pull or any other trick then I would suggest using the wifi recovery app on the market (not sure if thats the name or not). It fixed mine. Well, it fixed THAT issue.

[Q] Internet Not Working

Hey everyone,
So, I was using my nexus 5 in my university over wifi and it was working all fine and then all of a sudden the internet stopped and I couldn't browse or use any app that requires an internet connection. I switched off my wifi and turned over to my 3g connection and the problem was still there that is it would connect and everything but it wouldn't allow me to browse or use any such application, I tried restarting the phone, clear the cache through recovery, gave it a soft reboot but the problem still persists even with the wifi that I have at my home. I have tried opera and chrome and both of them are not working, neither is whatsapp, facebook or anything that requires an internet connection. Chrome says "erro code: DNS_PROBE_FINISHED_NO_INTERNET" while opera said "DNS lookup failed" and the same error comes over both wifi and data network.
Would really appreciate if someone could help me with it cause I need the internet to work on my phone as I can't carry a laptop everywhere. :/

try turning off your router for 3 minutes then turn it back on. about your 3G.. have you called your provider?
I take it you have turned off the phone and back on?

Strange mobile data problems

Hi.
I noticed that after being connected via WiFi for a longer time, e.g. during work at the office and then when I go out of WiFi range and phone switches to mobile data some apps don't seem to be able to receive mobile data or don't see the connection at all. E g. Waze (shows "waiting for network") and OnePlus community app can't read contents. Chrome browser works without issues at the same time.
Only reboot fixes it.
Anybody experiencing similar issues?
Not sure how related it is, but I was having problem with my vpn. When I got off wifi it would not automatically connect and apps wouldn't have data, there were some other symptoms that I don't remember now. Anyway going to developer settings and turning on mobile data always active fixed the problem for me, might be worth a shot.
Same here

Yeap, I use nordvpn, ones I leave my house using wifi and vpn, I loose data when switching to lte.
I don't have this problem with my op6.
Thanks for your input. So it looks like it would maybe be worth it posting about this issue in the OnePlus support forum.
I just noticed default 4G network mode is not the one I used to have on all my previous devices. (See attached picture). I'll try to switch to LTE Global and will be checking whether it changes anything.
