Weird problem with connectivity - T-Mobile Samsung Galaxy S II SGH-T989

The other day I was trying to log into Facebook app...didn't work. Tried using dolphin to log on..didn't work. Used my bimmer post app..that was OK. Gmail doesn't work..using dolphin to log into yahoo news worked. Hotmail is a no go..a lot of random sites would work though. Using WiFi everything is OK. Yesterday everything worked like normal and then today back to random connectivity. Oh I get notifications from those apps just can't launch them. Any ideas?

u have droid wall or android firewall installed? adfree?

sounds to me more like a problem with your ISP then your phone, does the problem ever occur on 4g? what about if you have even spent a extended amount of time at a friends or family's home where they have wifi as well. it could be your router at home. I remember I had a Belkin router that just didn't like my phone and once I got rid of it, I immediately saw more reliable connections over wifi

No firewall or anything of the kind installed. Problem doesn't happen with WiFi..it only happens connecting to mobile data. I tried pulling battery and sim card and that worked. I'm experiencing it again so gonna try doing that. I pulled only the sim out and problem still there. Facebook won't connect but xda app connects. That's how I'm posting this now. Its weird that certain apps and sites will connect while others won't.

on a secondary re-read I almost guarantee that's a DNS issue. Do u maybe have a social networking only data plan, or a data plan with certain restrictions perhaps?

[Q] Market server errors?

Both my wife and I (both on Fresh 3.1.0.1) are getting server errors trying to access android market tonight. Anyone else having this problem? Tried rebooting, tried routing through wifi, neither helped.
Just flashed king's kernel 4 and i'm seeing the same market issues.

Edited OP. 3G here is spotty, so I thought it might be that market refused to go thru wifi for some weird auth-related reason. I wasn't seeing packets going thru the router, at least. But I turned off wifi, verified that I was able to route packets thru 3G, and still no market.

Gotcha. I do hope they fix it soon. There's nothing worse that being bored and wanting to browse apps. It's funny because I normally don't browse much on the app store. Maybe it's my fault
theres a all around problem with the market for the last hour or so i just tested both my Evo and a old Samsung Moment laying around the house and both are having the same problem.(Also my Evo's Rom is the stock rooted 2.2)
I just flashed a new ROM and thought something was bad. Good to know it's not just me.
Same here.

It got me too, hopefully it's just some maintenance, although the least they could do would be to post a notice
It seems to be back up. However, I can't find some apps, and it's not showing free apps in the list anywhere near the top when I search (e.g. my wife just searched for "clock" -- she wants a new clock widget). I'm hoping this is a temporary problem.
Actually I'd really like to be able to filter to get just free apps on a search, but, no go on this.
I think they are SLOWLY getting it back up. I don't have top paid tab in my market. Its loading very slow, and a lot of apps are missing. Hopefully it will be sorted out by morning.

Network Connection Issue - No 3g/4g

OK, I have been dealing with this since I bought my GSII and cannot find any information about it.
Firstly I want to say that I am completely stock and unrooted.
My phone does not like to keep a stable data connection. About 50% of the time, when I try to do anything that requires a data connection (facebook, browser, gmail, etc.) the 2 arrows under the 2g/3g/4g icon will stick being grey and my phone just sits there "loading". I tried a factory reset, didn't install any apps, and also got a new sim card and the issue remains. It happens everywhere so it is not just a bad network connection.
I decided to post the question here because yesterday I was playing with my brother's GSII, and his did the same thing.. So it made me think that maybe it wasn't just me. Has anyone else experienced this? Or does anyone know what might be the cause?
Edit: I set my phone to use 2g only, and the problem vanished.. So it doesn't like to connect to 3g/4g.

Try going to your mobile network connection settings, choose access point names, hit your menu button and click "restore defaults".. It may fix it, I had data issues and it did the job. Hope it works for you!

Do what the gut above me said. Also call Tmobile and tell them, they will refresh your data connection on their end. That will clear up three problems your having.
But if it's also happening to your brothers phone, it's a network error. Call Tmobile.

I restored the apn settings and had Tmobile refresh my data connection, and it still happens. I noticed today that it's not just data, I'm also unable to call or text when it happens.. Tmobile just said everything tested normal so there is nothing they can do.. And I really don't think it's the phone so I don't want to exchange for a refurbished unless I have to.

Its happened to me before. For about a week, the data connection just dropped. It would come back for a bit and later vanish. I called t-mobile and they guided me through routine steps (i.e. taking the battery out, rebooting, resetting) but nothing seemed to work. They really couldn't figure it out and later told me to replace the SIM. I can't remember if they shipped me one or had to go to the store but either way that relieved the problem. This was on an HTC HD2.
That might not be the case with you though. At one point in time all the phones under my name lost data connectivity just as you explain. This really had no solution but to wait it out.

you mentioned your brother's is doing the same thing, its probably not the phone, but rather the cell tower your connected to is fuggin up. Try going 5 miles from where you currently are and see if its still happening.
Network error
Sent from my SGH-T989 using XDA App
Just in case it's not a cell tower or network problem . . . My SGS2, purchased in October, had the same symptoms as the OP. After trying everything the OP did, and more, I came to the conclusion that the firmware on the phone was corrupt. I used Odin to flash the factory stock ROM & Kernel images (2.3.5 at the time). There was a definite improvement in the faltering/hesitant/fail connectivity problem at that point, but it was still very subpar. So I then also flashed, again using Odin, the baseband ("modem") image - I did it twice for good measure. The problem was finally immediately solved at that point and I had very prompt loading of webpages, etc. Still working fine months later (and even better with a custom ROM). See the thread entitled "[Q]Is there a "true" factory restore for T-Mobile Galaxy S II?" for help about the seemingly same symptoms/problem you (and your brother) are experiencing. If your underlying problem is in fact the same as mine (and the poster of the thread I cited) then it's apparently either a bad factory flash or a post-factory corruption occurrence that is causing your problem . . . the coincidence of your brother also having the same problem aside. Good luck!

Home WiFi not working on E4GT

I obviously have the Sprint S2, and I continue to have issues staying connected to my home wifi. I have no problems connecting to other wifi networks. It will connect, then after a few minutes, it disconnects, even though it shows I'm still connected in my notification bar. I've searched high and low. It seems many other people are having the same issue, but no one seems to have a fix. Anyone here know of a solution? Thanks in advance.

So I finally figured out what the issue was. A lot of mobile devices have a hard time connecting to highly secured networks such as wpa2. If you have a wpa, or wpa2 protected router, you can only use numbered passwords. Up to 10 characters. I tried this, and it's the only solution I found. If that still doesn't work, change your wpa2 security to wpa, with a numbered password only.

Try changing the channel on the router, force it to a different frequency B or G only also.

if you have to use numbers and only 10 chars, it sounds like a router config issue. sounds like you have WEP on rather than WPAx
Wifi busted
I actually have the same issue. Wifi worked flawlessly on gb. On ics every time phone goes to sleep it drops, notification says connected. Toggle wifi off and back on works, phone sleep back off. Tried wifi never, only when plugged in. Switched to 2.4 ghz only tried 5 ghz , too. Linksys ea4500 wpa2/aes(setting) brand new. None of the numerous other devices in the house have any issues. Speeds seem awesome.
Tried factory reset nothing works. Even got sprint to get me a new phone, still no solution other than going back to el29. Currently, running fi03 stock rooted. Scared to try latest fi25. Any other suggestions would be great.

still sounds like a router compatibility issue. See if it happens on a different wifi.
The only way i can successfully stay connected is if there is no security or wep is used. Same router nothing had changed. Again worked flawlessly with EL29 update comes to FF18 and it no longer works. Sprint has said it is a known issue with ics on samsung and htc but no fix. Don't want to give up my security just to use wifi. If i roll back to gb everything works again without changing anything in the router. So i don't believe that is it. Plus, i know all about router settings not a noob. I beleive it to be something in the phone update.

My wife runs fully stock newest release and its fine. Try a different router. routers can have compatibility issues with devices. Also you say "its a known issue" but can you give a source?
I'm not saying its router settings. I'm saying it can be a compatibility issue between router and phone chipset.

I guess i should've mentioned there are 2 of the same phone in the house. Wifi works fine on the other device. Source? As in sprint tech support told me over the phone it was a known issue with samsung and htc devices, not all are affected. This is why sprint decided to replace my old non working phone for the new one.
Not sure why of it were truly a setting inside the router why would one work but not the other? Seems highly improbable to me, just saying. I do appreciate the feedback though.

So two of the same phones. One connects and one doesn't. Interesting. About the tech, seems a pretty wide declaration of an issue. samsung and htc phones. lol. There are a ton of those and its a 'known issue'. If it were a known issue, they would have it tied to a specific phone and wouldn't say 'well err um some phones work and some dont'. lol. Anyway, I don't usually trust those techs.
Back to the issue. If one works and one doesn't... Then it sounds software or still compatibility type issue.
Have you tried these things? If it were me, this what i'd try....
1) I'd reflash your phone's ROM fresh and try again. Full wipe. It's possible the update boinked your wpa_supplicant settings.
2) DHCP: stick a static IP on your android and see what happens. (dont confuse this with a static dhcp lease) DHCP does some interesting things on android phones as far as wakelocks and such.
3) In the router, turn off all the bell and whistle crap... Some of these routers have things like 'afterburner' and things like that. It can cause issues at times. Keep track of what you turn off and obviously if it don't work, turn it back on again.
EDIT:
This is interesting as well. Your not the only one.
http://forum.xda-developers.com/showthread.php?t=1847889&page=4
Try the things I posted but ultimately, you may need to just flash a different ROM version... Doesn't mean you need to go all the way back to EL26. At least you know its not only you...
So I initially called Centurylink, and they told me to change security settings. I did this, and it worked for a short period, but then dropped again. I couldn't figure out why this kept happening, and it had become quite frustrating. Then I realized that I had created a new network with a personalized name and password. My laptops connect fine to that network, but my phone won't, so I connected to the initial network created by Centurylink, and have had no issues. So I can suggest trying that as well. Hope that helps

Same issue for me too, since moving from gb. Running S710.10 S.FI27
I see this on both of the WIFI networks I connect with regularly. Home is worse. Every other device at home, including phones, PCs, TVs, tablets: mine and guests, can connect and stay connected just fine. My Epic 4g with ICS can't stay connected to save it's life.

different rom? mine never ever disconnects running cm10.
Set up both home networks using WPA/WPA2-PSK and no issues. Did have issues at work with WEP so perhaps that's the offending solution? If so try TKIP instead.

[Q] Cell Data Issue with 2 Apps

The NY Times and Wells Fargo apps on my Note 2 won't work will the cell data connection. Either the progress indicator spins endlessly or they report there's no connection to the internet. I use both these apps on a Galaxy S3 and they work fine. If I switch the Note 2 to WiFi the apps work fine.
Has anyone else seen these or other apps not work with the cell data connection?
Thanks
Wells Fargo works for me. I use opendns for dns server so don't know if that would make a difference.
Update
Yo I can confirm when using opendns set through rom toolbox is what is letting me through. When I disabled it I could no longer access it. After I enabled it again I still had to reboot to get it to work again.

Sent from my SAMSUNG-SGH-I317 using xda premium
Thanks both of you for checking, now I won't go mad trying to debug it.
The WF app just worked for me over LTE, and I was able to mobile deposit even.
Wells Fargo is still not working for me, but there was an update to the New York Times app today which fixed the problem. The notes said it affected "a small number of users". Why is it I'm generally in the "small number" for problems, but not in the lottery
Since my original post I've also noticed Flipboard will occasionally claim "no internet" and refuse to update. Hopefully that and WF will both be cured by updates.

No data sync on wifi?

In the last week or so, my phone has started some weird behavior on my work wifi.
If I'm using an app, I have network connectivity. But if I'm not manually refreshing, nothing comes through. After being on wifi there for a couple hours, then either leave or turn off wifi, suddenly I get a flood of emails, Voxer, group me, eBay, etc. Basically all data related sync notifications do not come through.
It gets more strange. At home on wifi, this isn't an issue.
Any ideas on how to troubleshoot the work network?
Thanks!

This is happening to me with gmail on my home Wi-Fi. Then when I hit mobile data my mail comes through. Tried multiple apps, factory reset etc and to no avail.
Seems like a dns block. Maybe your work has setup the network to block anything not work related. As it should be.
In another thread the app "telegram" is responsible for similar behaviour. Delete it.
