Problem automatic switching between wifi & mobile network - G3 Q&A, Help & Troubleshooting

Hey there,
everytime I leave my wifi-area my G3 keeps on looking for another wifi instead of switching to the mobile network. Only after disableing the wifi and restarting the data connection it connects to the mobile network.
Is this a bug or a feature? Got my new G3 for 2 weeks now and never had a similar problem on other (LG) devices before.

Go to Wifi settings advanced and try switching off "Allow Wifi scanning when Wifi is off" this should stop your device scanning for other Wifi connections when it is disconnected.

Never had that option activated in the first place.
Any other ideas?

Data connection problem when coming back from Airplan mode...

I've stumbled on a strange issue.
If I switch the Desire to the Airplan mode when the Data connection is off (I use the appropriate HTC Data connection widget to do this), when I switch back to Airplan mode off, the phone is no more able to restore the data connection.
The only workaround found is to restart the phone.
Has anyone got the same experience?
Two questions.
1. When you say you switched off data connection, are you talking about syncing, wifi, mobile network, ... etc?
2. Why do you want to switch off data connection and turn on Airplane Mode? Doesn't Airplane Mode cater for shutting down all wireless?
1. I'm talking only about the "Data connection" option on "Wireless and networks" menu, that is switchable via a special HTC widget. Switching this option off, the phone is no more able to access to the GPRS provider. I often keep this option off to save battery life. I turn Data connection on, if I need to sync and access to Internet.
2. This is not the matter, just it happens. Eg. When I go to sleep, I turn the Airplane mode on, doesn't matter if the Data connection is on or off (it is possible that it is on) in order to avoid any disturbs (calls, sms, etc.).
I just wonder if this issue is a true bug of the phone:
1. Switch off Data connection
2. Switch on Airplane mode
3. Switch off Airlplane mode
4. Try to activate Data connection (for me it seems it's not possible without a reboot)
Had a similar problem which I wrote to HTC about: after the phone has been data connected via wifi and I leave the wifi network it often will not connect to data via mobile network (GPRS/3G), giving the message "connection failed" if I try to manually connect in the "mobile networks" section of the "wireless & networks" settings page.
It seems to have fixed itself now, and I think it's because I've since ticked the option to "enable always-on mobile data", which I had turned off to save battery. Give it a try.

Thanks yurikg, but on my phone the "enable always-on mobile data" option is checked, anche there is no mobile network connection problem coming back from a Wifi connection.
The problem I shown is probably caused coming back from Airplane mode.
The other possibility is Juicedefender which apparently is known to cause problems recovering a mobile data connection (recent update may have fixed this):

I've not juicedefender on my Desire...
I've in plan to do some other tests...
I have a problem with my Desire reconnecting to a mobile data connection too, but not when I come out of 'plane mode, its when I leave a Wifi covered area. It could be the same problem, triggered by anything that disables and then reactivates the data connection?
I have no solution yet, and I have contacted HTC support about it (still no reply). There is some discussion here:
http://forum.xda-developers.com/showthread.php?t=656192
I seem to be having this problem too when coming off WiFi connection, unfortunately restarting the phone has not righted the issue...
I'm also having this problem with the connections. Fine on the wifi at work and at home but not switching over to the mobile network. Apart from that the phone seems awesome! Soooooo much better and more fun than the HD2.
OK, my phone appears to have no network connection whatsoever in fact...
Have the same problem as well. Coming from Wifi and to mobile network only - I do not get any data coverage. This is for the Desire and I had the same problem with Legend.
I hope this will be worked out ASAP.
Well, my problems all sorted. Turns out I had to manually input the APN for internet, took me by surprise since no phone I've owned since 2006 has needed that...
Just had to put in the settings manually too. Seems there is an issue with some of them. Would put a link here but as i'm a newbie not allowed Just google vodafone apn settings for htc desire and hey presto
Same problem here, my Hero had it too. I found it did work when you switch to gsm only and back to 3g/gsm... Would love to hear good solutions.
Im also having the same problem.
If i try switching my connection from wifi to mobile data, my mobile data connection fails to work. A power cycle fixes the issue but if i try switching connections again, the problem returns.
Can I suggest to anyone still having problems getting their phone to switch to mobile data when leaving Wifi to view the following bug report on Google Code and to star it to help raise the priority with Google:

[Q] wifi problems and some related questions

Hello
i have a htc desire gsm
and im running cyanogen mod 6.1.1 with radio version 32.49.00.32U_5.11.05.27
i have the following problems:
i can connect to networks without a problem, and the connection seems stable and fast
but reconnecting is a problem, if i disconnect from a network, by disabling wifi or moving out of range, most of the times the wifi does not auto reconnect. it just stays as remembered and disabled. if i then click on the saved network it connects fine.
sometimes it has to connect two times to get a conenction, looks like connecting, then searching then connecting in the wireless and networks config screen.
its not a big problem but annoys me as hell
on the other hand i have one network, protected with 802.1x eap (ttls and pap) its the configuration where you need to input username and password and use a certificate.
with this network i have connection problems, connection works 1 out of 4 times and if not then i have to redo the whole config. this annoys me even more because the network is unusable for me most of the time.
and
today i had the problem that the wifi conenction dropped regularly, connected, then came scanning which disconnected my wifi and then reconnected. and so on.
wifi settings even force closed then
had to reboot, after that was fine. lets see for how long
i have googled around but never found an answer or fix for this.
so can anybody help me here ?
and i have some related questions.
is there an app that can show me only wifi and related logs ?
is wifi connection related to radio version ?
where are the wifi settings located ? like saved networks and so on ?
thx in advance
I also have that auto reconnection problem. Waiting for a fix for that.
Does it manifest exactly as I described it or in some other way?

portable wifi hostspot

Having problems with my turning my phone into wifi hotspot (have uk orange htc desire hd chocolate). Turn on the portable wifi hostspot ok, my laptop and my archos 70i tab can both find and connect to it ok, BUT it dont work - on the laptop it just says local connection only - on the archos just wont connect to internet. most frustrating. also some problems with the data connection - phone shows the h or g icon and the arrows, but not connection when try browser etc usually works after a restart, but who wants to have to restart the phone every time you wanna use the data connection?
Any thoughts/suggestions?
Same hotspot problem
I ran into the same problem yesterday. I was testing if the wifi hotspot functionality worked, to use my phone for wifi tethering. As soon as I turn on the function, my data connection (3G) is disabled.
Doe anybody know how to keep the data connection after activating the wifi hotspot function?
Thanx in advance!

LG g3 WiFi issues

Is anyone else having this problem? My phone keeps dropping the WiFi signal even if I'm next to the WiFi router. The WiFi indicater shows good signal with all bars lit at all times and I don't get any notifications of signal being low but it still doesn't load/connect to anything. It's very sporadic, but regular.. once singal is lost it won't load anything for a minute or 2 even if the WiFi on the phone is turned off and on. I've tried resetting the router but the problem still persists. All other devices connected to the same WiFi don't have any problems. I'm using the virgin super hub by netgear.

Same over here. I have 3 other devices on the same router and none have a problem. Restarting the router does not solve the problem.

I have a similar issue at my partner's house. When I first got the phone I had no issues connecting to the 5 Ghz wi-fi connection, but lately I have issues with the 5Ghz, but connecting to his 2.4 Ghz connection works well. His device and other household devices work well on the 5 Ghz connection. It is annoying, but since the 2.4 Ghz seems quick, I am not going to worry too much about it right now. Hope there is a solution though.
I remember my z1 having similar problems...it was fixed by changing the security mode I think...wep..wpk...or something...just fool around with it...no harm in trying
I have a NetGear accesspoint that the G3 refuses to connect to regardless of the G or A bands. So frustrating.
Stard having this issue this weekend, thought it was the router location and I repositioned and still no help.
Hoping and update fixes it
I too have experienced issues with WiFi during my last 4 days of ownership. Perfect WiFi signal (I was sitting within feet of the router) yet no Internet connection. Cycling WiFi off and on fixed the issue. This occurred on two different networks using different hardware. Both were using WPA2-PSK authentication. No other devices on the network experienced any issues.
Go to WiFi ans hit the top right button and go to advanced setting than put yes on keep WiFi on when screen is off

That option was already enabled on my device. I never enabled it, so it must have been on by default.
Also, when this happened, my G3 still had a valid IP address
Have same problem since day 1. Cycling between 5Ghz and 2.4Ghz and vice versa seems to fix for the short term.
But seems to happen on a daily basis.....!
I have the issue has well. In fact, mine will sit at obtaining IP address.
i have same isuee
i have same isuue here with my lg g3 16 gigs model
wifi sigal drops all the time i did factory seetings and did not help
plzzzz help as am start to hate my device
add static ip address to resolve the issue
I added static ip address and it was able to connect to the wifi but it will
be the same problem when you connect to another wifi at a different location.
Do not change network prefix length/DNS1/DNS2. Keep these the same.
You could use this as temporary fix at home atleast and connect to wifi.
Disconnect completely from your WiFi, switch off WiFi on the phone, turn back on and go to advanced settings, uncheck the Google auto scan thing, then connect back to your WiFi.

Still have same problem
It worked on mine. Much more stable.
I am also experiencing this and it is really annoying. Toggling WiFi off and back on always fixes it, but that is not an actual solution because the problem happens so frequently.
I have tried:
Disabling Sprint connection optimizer
'Keep WiFi on when screen is off' is enabled
'Allow WiFi scanning' is disabled
'WiFi signal weak' is disabled (set so that it does not disconnect from WiFi when signal is weak)
'Battery saving for WiFi' is disabled
Using a static IP address
Factory Reset
Forget network
I still have had no luck. Does anybody else have any suggestions? I have about a dozen devices on my network and they play nicely; this is the only device giving me trouble. I am starting to wonder if it is time to RMA?
EDIT: It doesn't seem to happen when I connect to the WiFi at my work. Hopefully flashing a newer build of DD-WRT will remedy this. I love this phone except for that one issue; unfortunately though, this issue would be pretty hard to live with....
Same thing here. Before G3 I had G2 and Flex, both had the same wifi problem. Funny thing is that some $150 Chinese almost noname generic phones never have this problem on my home wifi. It's exclusive to LG.
Same Problem here. I am having a Nexus 5 sitting next to it. No problem with the N5 but constantly interruptions with the G3. This phone is starting to annoy the hell out of me.
I have the VZW G3 rooted, have no issues with WiFi on either antenna using an Asus dual band router.
I did have issues with a dlink, but it had issues with all phones not just the g3 so I replaced it.

Wifi network not found

Hi.
Since a few weeks I have a strange problem with my Wifi connection.
When I'm at home and turn on Wifi everything works fine for some time and my M9 connects to my Wifi. But after some time (haven't found a rule, sometimes after 1 hour, sometimes after 5 hours, etc) the wifi connection is lost and my network is no longer listed in the list of available networks. It also seems like the list of available networks is getting shorter the longer wifi is turned on.
If I turn of wifi and turn it on again after a few seconds my network is found immediately and the phone connects without any problems.
I'm not 100 percent sure but bluetooth seems to have almost the same problem and the phone no longer connects to my smartwatch until i turn off and on bluetooth. Sometimes it is also ok to turn off and on bluetooth to get my wifi back running.
The problem started to exist on lollipop and is also present on mm. I already did a factory reset but it didn't seem to help.
Anyone experiencing the same problem or has any clue what it could be? Maybe a hardware problem?
Kind regards,
TeQuiLLaXY
Perhaps a router problem ?? Or a service provider issue with WIFI ?
Does the device connect with other WIFI signals other than your primary signal ?
Just a few other areas to check beyond the device that can be overlooked...g

Hi gregsarg, thankfs for your reply.
The router doesn't seems to have a problem since other devices have no problem to connect to it. Service provider has nothing to do with wifi, the phone is not connecting to the wifi it has no problems accessing the internet via wifi when it shows it's connected. Also the connection can be established as soon as i disable and reenable wifi on my phone for about a second.
I don't have access to the other networks that are around my home so I can't check if it connects to other networks, it's just strange that the device does not show my network in the list of available networks after it has lost connection. If I disable and reenable wifi on the phone it immediately shows my wifi in the list of available networks. SSID is not hidden...
Could be hardware related...
And you could RUU back to stock and test again to rule out a software issue...g
