No mobile internet after wifi disconnect - Samsung Galaxy S9+ Questions & Answers

Hello everyone
A week ago I bought my Galaxy S9+. Sad to say that I've been having connection issues. When my wifi connection drops neither apps nor browser can connect to the internet even though the 4G logo is present at the top bar. To resolve this I need to do a reboot and then everything works normal.
Anyone have an idea what the problem might be?
Does this seem like a problem I could fix myself or should I return the phone (which I prefer not because of the hassle)...

Hi, have you found any solution to your problem? I have a similar one and it starts doing that after the last update in June, before it used to work fine.

No Data When Going from 3g to Edge?

I've been having this problem for about 2 weeks now. First I was using Radio 1.50 on the AT&T network in South Jersey and out of the blue when the connection would go from 3g to edge I could no longer connect to the internet, receive emails or anything, voice was fine. When I would get back into 3g range everything would work again. So I upgraded to radio 1.54.07 and at first everything was fine no problems what so ever. But after 5 days this radio does the same thing, I cannot do browse the web or get my email if i go from 3g to edge but everything works fine once it is in 3g range. Anybody have similar problems or know how to fix them?
Just to clarify things, when it switches from 3G to Edge my phone still shows that there is a data connection but for example if i try and look up something in Opera it says looking up host and then times out. Any program trying to use the data connection times out, which is weird since I never had any problems til about a month ago. I've tried soft reseting and still all it will find and connect to the gprs signal but all my connections time out if i try to look anything up
I have the same misterious problem. Did anybody - especially jc67 - already found a solution for that?

[Q] Wifi dropping even when it shows it's connected (w/ Video)

I've had two Galaxy S II phones now, and I've had the same problem with both devices. The phone's wifi is great -- when it works. Although I noticed that the death grip lowers the wifi signal bar, I can still browse the internet and download apps just fine.
The problem is that, at times, the phone will show wifi connectivity and yet, I can't browse the internet or access the App Store. I'll have to shut off the wifi multiple times and even this doesn't work 100% of the time. Shutting off the phone and turning it back on works 100% of the time.
Since this has happened to two phones, I'm beginning to question whether I have an issue with the wireless router because I have not come across this as a prevalent issue. At the same time, my laptop and a family member's iphone doesn't have the same issue.
Anyone else having this problem? Or have suggestion for fixing the problem?
Thanks
Here is me showing the problem on video:
My roommate and I both have the Galaxy SII and he constantly has problems connecting to our wifi. The only difference in our phones is his is rooted and mine is not. I plan on rooting my one of these days but would like to fix the other issues I am having first.
Mine isn't rooted, but it still has the connectivity problem.
EDIT:
I may have found the the solution. Probably unique to my situation, but what I did was disable WPS on my router. It's a medialink router and I thought I had disabled it (per instruction) but it was on. Perhaps that was the issue. So far, no problem.
EDIT:
Nope, the wifi has dropped again. By dropped, I don't mean it drops in the middle of browsing. It seems to drop after I've stopped using the phone for a while. I've already checked to see that the phone is to never turn off the wifi when the display is off/sleep.
Arghhh
same exact problem.

Don't have any issue with wi-fi , mine is rooted on stock rom
i have no issues with wifi on my sgs2, i have wifi on 24/7, and on wifi proabably 50% of the time. it connects and disconnects when supposed to, picks up on cell data and drops when its supposed to..
fwiw, my GF has an iphone 4, she had problems connecting to the HOME wifi, but no where else, i updated the firmware on the router, same problem, i swapped out the router for a spare a friend had, and setup a second access point on the same network, just called it the same SSID but put a "2" after it.
her connectivity problems went away, immediatly she noticed a difference and has never complained of a drop since...
try different encryption methods, if you're using wep, try wpa, try a few different things.
also try a firmware update, you might lose your settings during a firmware update, but there is usually a backup/restore option you can use. backup your settings before flash, then restore after. if you have access, for at least testing purposes, hook up another router and use it to connect to and see if the same problems persist.
No problems at all connecting to a WHR-G54S running Tomato.
The Moto Surfboards are known to be flaky.
I had the same problem. after getting another one I found out that if I didn't download so many apps at one time the problem mostly stopped and after running a couple weeks, I haven't had the problem with connection since. I'm not sure it will help, but I did a factory data reset and reinstalled the apps one our two at a time (it's frustrating, I know).

[Q] Samsung Galaxy S3 Data freeze.

Hi,
I'm new to the forum so apologise in advance if this is a stupid question.
I recently bought a Sim Free S3. I haven't rooted it as i'm quite happy with the stock os for now. Everything had been working very smoothly on it. But since getting the over the air update for it my data signal randomly drops out or freezes. It seems to do it over WiFi too. It does this even though it shows a wifi connection or with the H+ visible. I've also noticed it cycle through H+ to 3G and back again.
Sometimes the signal works again on it's own and other times i have to switch the phone off and on aain.
I find it happens on tweakdeck the most but has also happened whilst browsing the net.
Do you think this could be linked to the update or could this just be a coincidence and there's an underlying hardware fault.
Let the new update run for a little bit...let it settle in
It might just be the spot u in and I doubt its the phone
Might be uodate but how long u been on the update?

Think the update came through on Tuesday.
Will give it a few more days to settle and see how it goes.
Thanks.
Still having an issue with this.
My internet worked all weekend then today started to fail on me again today.
The phone shows a HSPA connection but will not download any data.
I know it's not the network as my wife is on the same network and is having no issues.
Any help will be greatly appreciated.
Same problem
I am having the same problem here. I just bought SGS3 about 3 days ago and I started noticing data drop out yesterday. I wish someone could help me. I was hoping the problem to be solved by the time we get firmware update.
BTW, I am also having problem using usb tethering or wifi hotspot. After using usb tethering for about 10 minutes, it stops connecting although the phone still has data connection.
Is it hardware or software problem???
Thanks!!!
having the same issue after power saving goes on i lose h+ until god knows when

[Q] Network Issue

Hey guys I've had my S3 for a few months now and after a few days from purchasing I received a WiFi problem in which the device disconnects from the connection and reconnects after a few seconds and this happens simultaneously.. I didn't contact Samsung then because I thought it would be fixed after updates and installing a few ROMs and tweaks.. But I bore with it too much now for 4 months and it is really annoying me.. The recent problem now is that it connects to the WiFi and HSPDA+ but never sends or receives information, like i can't use data/internet at all.. i tried many things but it never worked, not even updating to the latest 4.1.2 helped solve the problem..

[Q] Wifi connected but no internet connection?

Has anyone else experienced wifi issues with their 920 where it's connected to the wifi, but there is no internet connection? It has been working fine since I got it back in November, then yesterday I noticed that when I was trying to open skype it just said connecting... forever. I tried IE and got nowhere, same with the people hub updating.
I eventually decided to reset the phone, and of course it then got stuck on the spinning cogs, so had to go through the whole mess of flashing the phone with the original EE firmware which did luckily bring it back to life. Then when it was running again, still the same wifi problem!!!
I eventually managed to get internet through the wifi again (for now) by switching the security from WPA2/PSK to Mixed WPA & WPA2, and then I switched it back to WPA2/PSK and it's kept on working now. But why did this happen in the first place as all my other devices (wife's iphone 4 and 5, surface tablet, latpop) were still getting internet through the connection no problem?

Click to expand...
Click to collapse
This sometimes happen to the L920, a reboot will fix the problem....L920 have still a lot of bug... so if you do not want to kill you phone, stay away from BAYGON
On what channel is your Wifi operating? I have seen People Report Troubles when their Access Point was set to operate on channel 12 or 13. Those are not available in all countries so that might be the reason.
Other than that I have no idea what the issue might be.
Reboots didn't help.
After a lot more investigation, firmware upgrades, tweaking of pretty much every WiFi setting under the sun, it looks like the issue was being caused by the two netgear WiFi bridges I've got attached to my sky boxes - every so often they randomly seem to interrupt WiFi connections from other devices - my wife's iPhone started having issues and when I necked the ip details, it had the netgear bridge ip as its gateway. Resetting both bridges seems to have solved the problems so will have to be my first port of call for any future issues!
