Data Connection works but just once!

Hello,
1. I switch my Desire on (the smartphone heh!).
2. Everything works fine when I switch on the Network connection (Internet OK, syncing OK,...).
3. I switch the data connection off.
4. Later, if I want to switch the same connection on again, well it doesn't.
I hope I made myself understand.
Any idea?
Thank you!

If you switchit off/on with the Mobile Network widget sometimes it stays off/on.
Try deleting and then adding the widget back or switching on/off from the settings->wireless networks ..
Or, of course, rebooting the phone..
(sometimes the widget does'nt do what is supposed to do)
cheers !

Unfortunately, it isn't a widget problem!
In the settings, it says connection failed... (at the second attempt)
Of course, rebooting helps but it is a pain in the...
Thank you anyway!
Any other suggestions?

Delete the APN and then put it back.
And if you have APN's that you do not use, delete them.
Give it a try, maybe it helps.

While you are connected (via GSM) are you trying to connect to wiFi networks too?
Because I found a problem with connections.
When I:
1. I connect via GSM
2. then I connect to a wifi network
3. then if I leave he range of wifi my GSM connection does not work
The only solution is to switch of GSM module and turn it on again. To prevent this I always have to disconnect from wifi correctly.
I hope it's understandable.

Had the same issue, could only get it to reconnect after switching phone off and then back on, returned the phone, got a new one and now seems to be OK

[Q] T-Mobile WIFI calling issue from behind corporate proxied-connection

I have no T-Mobile tower reception at work, and was looking forward to the wifi calling capability to come to the rescue with this new phone/service. Unfortunately, my work wifi requires a proxy-serverort for browser connection, and once I update the wireless connection with these settings - I am able to browse fine.
Regardless of the wireless signal strength, the WiFi Calling status states : Poor WiFi signal, before timing out with REG99 error - unable to connect. I have also noticed on this phone and the HTC EVO 4G, that while on wifi at work, my download speeds (via speednet) are high (>10mbps), but nothing shows up in the upload section.
Given the above, and knowledgeable of the fact that my corporate network does shut down access to other ports - is there any workaround to enable wifi calling behind a proxied network? I have even tried to add a new APN to include the proxyort to no avail.
wifi calling from the home network works without any issues, and yes i am rooted.
TIA for any help.

Found the solution. Turns out that accessing the proxied wireless network was the root cause of the issue. We also have access to a guest network, that interestingly does not require a proxy connection to the outside world, and that works perfectly fine!
Still unanswered then, is what ports does this phone require that are being blocked by the proxy server?

I would also like to know the answer to this. I do not have access to another wifi server to test this. What is weird though is that my Sensation that I just got rid of had no issues with wifi calling on the same network, explain that!

Smart Network Switch option Missing?

I have a Verizon G4 and have one major gripe.
At my workplace, the wifi is somewhat spotty and it's a guest network that requires authenticating (clicking an "i agree" button)
So my phone will, throughout the day, as it detects the "weak" signal, automatically turn off that network due to "unreliable internet connection".
Even as I'm back in an area with a strong signal, now my phone is ignoring that and stuck trying to use mobile network. I have to go into my network list and manually tell it to reconnect.
During all of this, wifi is enabled the entire time.
I see where others have had the same problem on other phones and have turned off "Smart Network Switch" and I even read where someone had done this on a LG G4 (not verizon).
So I'm thinking this is something Verizon removed. Anyone have any ideas?

Smart Network Switch is just a feature that checks for a "data" connection over wifi and switches to use Mobile Data if WiFi loses internet access.
I am not sure the G4 has this. When I am connected to WiFi with a bad signal, it will just send me a popup telling me the WiFi has no internet access and whether to use Mobile Data or not. The feature you are looking for is "Avoid bad WiFi Connections", which is the same thing with a different name. Just make sure that is OFF. That will force WiFi to use WiFi as the only connection.
And it sounds like your wireless network sucks and needs to be upgraded to a corporate solution.
Just FYI, in my WiFi > Advanced WiFi settings, I have everything unchecked + "Keep WiFi on when screen is off" = Yes.

Well "avoid bad Wi-Fi connections" is off. Read on another forum that the mobile version I think it was had the smart network option.
I have the same options as you except I also allow Wi-Fi scanning.
I have tried with that one both on and off and see the same behavior.
I never get a popup, it just ignores that wifi connection and used mobile data. When I look at my Wi-Fi list, it'll say something about unreliable internet connection in small text,on the Wi-Fi network that it disconnected from. Surely I'm not the only one seeing this.. :/

Beats me. Sounds like the Access point you are connecting to has a bad internet connection. What is happening is you are connected to the WiFi and it notices that the WiFi AP is either dropping internet connection (Google pings google servers to test connections) or bouncing.
In order to keep from losing a data connection, it seems to be switching to your cellular network.
I see this often because we install APs (I am a network engineer). I think your phone is trying to protect you and that is normal behavior. Here is another scenerio: In a hotel, wifi is always set to OPEN. If your phone automatically connects to the hotels network, you will lose a data connection because Hotels require you to "sign-in", just like most free wifi places do. The phone sees that your phones WiFi connection is not accessing the internet and making sure you are good.
I am not sure how often it "checks" the wifi for a good connection or if it ever does once it switches.

Using WIFI will terminate my Mobile Data connection after turning it off

Hello guys!
Here is the deal. I hope somebody is able to help me. I have a galaxy s6 920p with the ramified ROM (OH1 version on OI1 band) that works perfectly except for this weird issue. So, i am in Peru and i unlocked my phone, it works perfectly with my local carrier on LTE or 3G depending on the coverage EXCEPT when i connect to a wireless network(WIFI), if i do so my LTE 3G icon will dissapear as expected and be replaced with the WIFI bars and i would then be on Wifi internet which is fine. The problem comes when i move away from wifi signal or turn off the WIFI myself, the signal bar will remain full and i can make and receive calls normally but there will be a "!" sign next to it indicating that the mobile data is not working, the only way to fix this is by either rebooting the phone or setting it to flight mode for around 10 seconds and then bringing it back to normal, which makes my mobile data start working normally until the next time i turn on the WIFI. I have also noticed that my APN gets unticked everytime i connect to WIFI, regardless of this sometimes (i would say 30%) if i turn off the wifi the 3g/lte connection will resume normally. I am a pilot and sometimes i keep my phone without airplane mode, in the air i lose signal but as soon as i regain ground i recover my lte/3g, so this also indicates me that is not something related to the reconnection of signal itself but something regarding the WIFI. I hope you guys have any clue of what is going on here because it is really annoying and i haven't found any info about this. TY in advance!!!!

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
