In Android, I noticed that my data connection is lost from time to time. The modem application (the one that always comes with our builds) shows me this message when it gets disconnected:
PPP connection went down.
Done.

Well, I think that when this happens, the connection should be reestablished again, but it is not. This way Gmail is not receiving e-mail anymore. To solve this situation I have to go back to Modem, press Disconnect and Connect again. Then, after some seconds, it connects again.
This task is very tedious. Is there any way to keep the connection alive? or to reconnect after it is lost?
Thanks!!

I tried the Feb 14th zImage and initrd.gz from the HTC Android Sourceforge repository on my Orbit 2 (Pola 200) and had quite a stable PPP connection. I think there's some changes in initrd.gz that deal with pppd.

Check out the application KeepConnOn in market...I believe it does exactly what you needed.
After trying the app, I confirmed that it doesn't fix this behavior.
Sometimes the connection is active, sometimes it is not. Isn't there any way to reconnect automatically when the connection is lost like in Windows Mobile??
PLEASE! This is a major problem for me, mainly for Email receiving.
Is there any way to reconnect when the connection is lost? It's terrible inconvenient, because you may think that you are receiving mail messages, but you actually aren't. Suddenly, every access to Internet is impossible and I've got to go to the modem app to disconnect / connect. After 10-15 seconds, the connection is established again...
It happens really frequently! Help me, please!

Only 2G mode can maintain your connection alive in standby all the time without problems.

On my phone do I can't see if you have a signature. It would help to tell us which rom you have installed, like JH7. That would make it easier too troubleshoot.
Sent from my SAMSUNG-SGH-I897 using XDA App
official att JH7, nothing rooted or modded in any way
I get this exact same problem. The Wifi on my phone sometimes works, sometimes does not (although it says it is connected). I too have had to reboot my phone just to get it working again...even then after it stops working after 30-ish min.
I also am also having other issues after the official update as well.
1) cannot add a gmail account for syncing on my phone.
2) cannot connect to AT&T server when trying to find an update.
I went to AT&T for the three issues that I am having and they were unable to find a fix, we even tried changing SIM cards.
Sounds like you have a corrupt file somewhere. You could always get the Odin3 one click here, do a master clear (same as factory reset), flash back to stock, download Mini Kies EXE File here to get back to the JH7 build. [HOWTO] Update to JH7 using Kies Mini (USA) just in case.
Just make sure you read the Odin steps, if you haven't done before.
Hope that helps.
Hi all,
I have a Galaxy i9000 and it won't connect to wireless. It used to connect just fine, then one day it stopped working. I ignored it for a while (3G still works) and once I finally got around to trying to see what had happened, I could see that the phone does connect to wireless networks (at home and at work), but once it had authenticated to the network, it would fail at "Obtaining IP address from <network name>". There's no error message, but the phone just sits at that stage forever. Not obtaining an IP address makes it pretty hard to connect to a wireless network
I don't know what happened to make this problem occur, it's been about a month now since it happened. I have AdFree installed on the phone, that writes to the hosts file, right? I suspect that it may have been a hosts file update which had caused this problem, but I'm not sure.
Does anyone have any suggestions as to what may have caused the problem?
Thanks!
what about reflashing your phone?
so you have everything stock
if this doesn't solve the problem then contact a service, or if you have warranty, just send it back...
same problem
The funny thing is is have exactly the SAME PROBLEM ... SINCE the same time?!?!
mybe we got some kind of virus for phones? ... altho i do have anti viral software on the phone. and i didnt upload any kind of stuff on it for at least half a year.

I am also experiencing similar wifi issue..except I get pass obtaining ip address it's after that I get error message "authenticate problem".??
My brothers works fine connects within second on home wifi, when I connect on same wifi I get error message..I have tried restoring previous wifi data..I have done phone reset too but nothing works
I did some googling and found brief answers not that helpful..but it was mentioned that frequency range I'm trying to connect is incorrect.
"does anyone know how to change wifi frequency mgh our any help"
question
Hello , did anyone solve the problem ? My I9000 wifi problem apeared today. thanks
same "authentication problem"
Well after i flashed custom rom (android 4.0.4 -SmoothieICS-v2) i can´t connect to wifi any more. But mobile data works perfectly.
And before flashing custom rom ,wifi worked jsut fine. phone is Galaxy S Plus I9001 .
Hi, I am trying to get an idea of how many people this is affecting.
I am on my second T-Mobile Galaxy S6. The first unit had a hardware camera defect as well as this wifi bug. I had them replace it and the new unit's camera is good but it has the same wifi issue. Here's what happens:
When I go to an area with an "open" wifi network, a notification pops up on my screen that says "Click here to connect to null." What's strange is I have almost all wifi features off, particularly "Network notification." It should not tell me when any network is available. I also have "Allow Always Scanning" off as well as Wifi Calling disabled (not that relevant). Anyway, once this happens, I have about 2 seconds to turn off wifi or else the phone will reboot. It's a "soft" restart though, meaning it shows the Samsung and T-Mobile logo then is back on again within 5-10 seconds and fully "booted" within 30 seconds. This will keep happening until I turn off wifi.
It's not just any wifi connection that will cause the issue. I think it has to be an "open" connection that uses a portal for authentication (think universities, hotels, airports, etc). Recently, I clicked on one of the notifications (connect ot null) and saw a Cisco portal. I am not sure if it's isolated to Cisco AP's
I have found about 4 people so far that have reported this issue. I am guessing we are not the only ones. I am guessing it's a software issue.
Have you seen this?
Yes, I have the exact same issue. Sadly I dont know why it's doing it or how to prevent it. I'm located in the Netherlands and when I click login the browser directs me to a KPN Fon login page.

I am very confused what's causing this. Can you confirm what settings you have enabled or disabled? Wifi calling, advanced switching, always scanning, etc? I disable everything and still get it. So it seems like it's not just Cisco login pages. It's also FON. Do you have any areas in your city that have public wifi hotspots with login pages like McDonald's or Starbucks or a university? It'd be great to see if it happens at those locations too.
I don't have wifi calling, advanced switching is disabled, always scanning is on, keep wifi alive in sleep is on. I will check when in the neighborhood of public wifi spots. to see what's happening. Only solution for me now is not using wifi, but that's not very desirable. Have you contacted Samsung about the problem?

Yes they told me the same things you'd expect. First they said to restart the device. Then clear cache. Then try safe mode. Then finally to do a factory restore. None of these items work. Just curious, is there any way you can easily give me a dump (plain text list) of your apps installed, in a PM? I wonder if it's something software related. I can do the same but I just need to find a tool that can do it.
Edit: I found an app called "List My Apps" in the Play Store. I can't link you because I don't have enough posts under my name. Hopefully I can send you a PM with my list to compare.
wifi null and reboot Samsung galaxy s6
I have the same problem like other guys. My S6 reboot continously when the wifi is on and I am I'm the City ( Zürich -Switzerland)
Then only solution was to switch of the wi fi.
Anybody else expierencing the same issue?
Regards
I'm having the exact same issue. AT&T Galaxy S6 in Southern California.
How do we get this fixed? It's not limited to a provider (that's good).
I already exchanged a unit for the camera issue. I think I am probably past my date for another exchange and quite frankly the first one was such a pain to go through, I'd prefer not to. Anyone have any ideas? I am guessing it's some sort of software issue. Something trips it up when the phone is near a captive portal.
I'm not sure swapping units will help. I did that but it didn't fix it sadly. I contacted SamsungNL and they told me to go to a Samsung repair center to show them the problem. I will try to do that next week. Until then, mobile data only.
Hi guys,
I have contacted Samsung UK and they told me to bring the phone back and ask for a new one. This is not normal and we need a replace.
In the meantime I have try to install FXR wifi Fix and Rescue from play store. Did a reset of my WiFi with this app and since then Its working everything ok. No more Reboots in the last 5 Hours. I was also in public and crossed a lot of open networks but did not report more this issue.
Give it a try.
Regards

Samsung UK support are idiots. Seriously, they tell you to return the device for software faults. I contacted them about the LTE signal showing incorrect in the settings, a clear software fault, they said to return the device.
Honestly, Samsung support is useless.
I think no way to stop it atm bcoz it is a software issue, we'll need to wait for an update. I think the baseband of wifi/bluetooth is still not stable, today I heavily played with bluetooth and got a soft reboot too.
Luckily, my HK firmware got no wifi calling and any bugs, my wifi is fine.

This seems to be working. I also ran it and it fixed the problem. I think this points towards a faulty wifi database or something.

Thanks for posting this. It's the first attempt at a solution I have found. I am going to have to agree with others and say that replacing your device did nothing to help solve the issue. I think its a software issue, perhaps with the wifi drivers or database. I tried running FXR but I won't know if it worked til I get near a captive portal. Keep this thread going guys. This problem is frustrating as heck.
So guys,
I am Happy. In the last week (After I ran the FXR app) looks like the problem is solved for me. No one reboot and any problem with. Null or open networks.
Got 920f model but im not sure is the wifi problem on my phone or not. Phone keep rebooting itself in my pocket. 10 reboots minimum during the day. Tryed flashing another rom but same nothing changet. Not sure its a hardware problem or software.
Will a replacement fix this issue? I'm about to do it tomorrow. But I'd rather not do it if it's not necessary.
UPDATE: I replaced the phone, it did not fix the issue. Seems like we need to wait for an update, unless I am extremely unlucky.

I took replaced my device, but for a real camera issue, not the wifi bug. I agree with Stolpler, running the FXR app completely fixed the issue for me.
For those new to this thread/issue, let me try to explain what's going on and why a phone replacement doesn't work.
The issue is entirely software and I think what's happening is that for some reason, a small amount of us have some corrupted entries in our wireless login database. We all know that if you get a new Android phone and sign into your Google account, all your saved wifi credentials (home, work, school, etc) will be automatically migrated over. That's why you don't have to re-enter your wifi password. For some reason, one of these entries must have gotten corrupted for some reason. Another possibility is for some reason, the way the S6 expects the data/format is different than how Android normally stores it. So say you had an entry from your Nexus 5 for a hotel login. Then now that you're on your S6, it tries to read it and it doesn't like the format so it blows up.
Now, the reason why a phone swap won't work is the moment you sign in with your Google account, it will transfer over your wifi database/settings. If you get a new phone but don't login (ever) to your Google account, I bet the wifi issue would not exist.
With all that said, really, go download and try the FXR fix. It works, it really does.
After getting N5 updated to the 5.1 update whenever my phone goes into deep sleep the WIFI turns off (yes I have checked the option to keep WIFI on during sleep). But it's really frustrating as I cant get any update on my mails and on messengers. Tried 5.1.1 custom roms, they are also facing the same problems. Are you also facing this problem ?
Nope, never

I would check your router, I remember a year ago my router started kicking off people for no reason on WiFi.
Found out it wasn't the devices but the router itself so I replaced it after seeing it was faulty even after a reset and now those devices were working fine.
So check your router's firmware, try a power cycle and whatnot.

Sorry to maybe dragging up some thing you've already tried but have you got "scanning always available" turned on (the Google location one in wifi - advanced)
Good luck.
