[Q] I keep getting: - "Data Connectivity Problem - The server failed to communicate"
"Data Connectivity Problem - The server failed to communicate. Please try again later"
I keep getting this message when I try to connect to some websites.
How can I overcome this situation please??
I have searched this and other forums but not found the answer.
I have tried resetting - power offs - etc, etc but this message keeps appearing and I remain totally unable to get onto some sites that I need to spend a lot of time on.
I am in UK on o2 network but use wifi most of the time.
Help please.

I have also now tried sim cards from Tesco Network and Vodafone Network but still get the same result.
Please help me if you can

What rom are you using? The JMG rom for example has wifi connectivity issues. Or are you having trouble using cellular network?

Not sure what ROM I am using (i am unsure of how to find this out) and yes I still get same issue when using cellular network.

The problem is your browser is not compatible with your webserver. I had this problem back in blackberry days. Download dolphin or opera to see if a different browser fixes your issue.

I suggest for you to search around for a APN setting that suits your network provider. Sometimes it may be caused by that.

Wrong apn settings would keep you from even connecting to your cellular network. You wouldn't be able to get any message.

Same here
I've had my tab for only a few weeks, and have had a very shaky wifi connection because of the same error you get.
With the wifi I can logon no problems, but I continue to get the error you mentioned. The stock browser is essentially useless with this, so I tried many others. Dolphin HD, Opera Mini & Mobile, Miren, and Firefox beta were mostly better, but still not really useable. The best I found (even though I think some of the others are better browsers) is Skyfire. It doesn't seem to suffer the wifi issues to the same extent as any of the other browsers.
The wifi issue seems very strange, and I think it is more my ageing Netgear router. It doesn't work well close up when I get a full strong signal, but is acceptable (not good) when I am in the next room or even outside. The only thing that really worked was switching back to b from g, but I didn't stay with that for more than a couple of days because of the speed difference.
I have also flashed to Rotohammer's latest ROM JMI (unfortunately with the same issue, and no GPS).
I will continute to try various things I find around this forum, but as you say, no one seems to have an answer.

Thanks but I have tried Opera, Dolphin, Skyfire but am still unable to login to some sites such as the OPDA forum in China that I want to use.

Thanks but my APN settings were provided automatically by my network provider and I have checked and double checked them and even tried editing the APN settings but without success.

As mentioned in a reply above - I have already tried Opera, Dolphin and Skyfire but still get the same message when trying to login to my account with the OPDA Chinese forum specifically and SOME other websites or forums in general.

Do you know anything about tomcat? I googled your error, where I found out about the browser incompatibility, and it could be on the server side.

Well I have had a "slight" success in that I installed Mozilla Firefox and it allows me to sign into the "offending" websites/forums etc.
It is slow but at least it is doing the job!!
Any other suggestions would be most welcome.

You are not alone in this frustrating issue. I have a T-Mobile Tab and I constantly have data issue when on the celluar network. I constantly have to reset the data by turning off and on airplane mode or holding the power button to reset the data and as a last ditch effort, I just switch it to GSM only *Shudders* Wifi works flawlessy. Data on the other hand is shaky at best. I will try another browser other than stock today. Honestly I suspect the issue to be APN related because it's definitely not the SIM card related, as i've changed that several times. Any help would be greatly appreciated

Rangercaptain - I found this reference also, but could not figure out where this server might be. Logically there is only my tab, router, adsl modem, and my internet service provider (Telstra). I could only think that the 'tomcat' server could only be within Telstra, but also thought that if this was the issue there would be many more people complaining about this isue.
Can you throw any more light on which direction I should look to follow this through? I am also puzzeled about where I might change things to make my browser 'compatable'.
Thanks very much for your interest and help.

I am still looking. The server in the reference would be the sever that hosts the website you want. I will check back here later when I know more.

Thanks - I think you are right. My only problem is that the problem occurs on manywebsites, and even on Market and other internet accessing apps. While this could still be right, I don't see why many more people wouldn't be having the same issue.
It also puzzles me that changing the modem from g to b decreased the error significantly, as does moving further away from the router when it is in g mode.
Very confusing.

Please Help (data connection problem and one more)

I have tried searching and searching but i cant find any solutions to the problems in my Samsung Galaxy S2.
1. Data connection doesnt not turn on automatically when i leave my wifi area.
2. BBC iplayer does not play anything for me both in the app and in browser. i have latest flash and adobe air installed.
Thank you

i have used the search tool here nothing specific to my problem.
my data is always on. when i turn on wifi, wifi connects very quickly and when i leave my wifi area, theorotically my data network should take over from wifi but it doesnt happen.
i never had any issue with any other android phones i have owned before such as HTC hero, Xperia X10.
i connected my phone to kies today, it could not detetc it so i turned off usb debugging then i could connect to kies. i checked for update there is no update available. i think i have to flash a different rom using ODIN.

hmm ok , yes , I would recommend flashing other rom , but first give it a try to the newest stock rom , my thoughts..!

Wifi connected but doesnt work.

We have 3 SGS2 at home and a Billion 7800N modem
There is a recurring problem on my wifes phone where there is no dataflow. I cant even reach the modem. It will just start working all the sudden for a short period then stop again.
Things I have tried.
1. Using it right next to the router
2. have tried using different channel
3. have reset modem
4. made sure sleep policy is on never
5. Update firmware and hard reset phone - no new apps installed - worked at first but now having problems again.
It never loses wifi connectivity....internet just does not work. Turn 3g on...works fine.
What could be the problem?
Only things I can think of
1. Faulty phone
2. Virus? That phone is sometimes used to check out Chinese websites...and I know some of them can be dodgy. I forgot to ask her not to go to any of those sites after the hard reset as trial and error.
3. Not certain but this problem may only started when we updated to 2.3.4.
If need be Ill hard reset AGAIN when XXKG6 is out - I dont want to flash back to 2.3.3 to try

I have the impression, that the Broadcom WiFi drivers of Android are still buggy, because my Asus Transformer's WiFi also isn't very good.
When using a static IP address and setting Google's free DNS 8.8.8.8 as a secondary DNS server (the router as primary), my SGS2's WiFi works best.
Maybe give it a try.

I have the exact setup and tried all the things you mentioned to no avail. It works sporadically after I reset the phone wifi on and off but it won't maintain data connection for long. Although the signal indicator says it is still connected. the billion 7800 works on my wifes sgs and connects without problem to my work htc legend.

If you google for "galaxy s2 wifi no internet", you'll find out, that several SGS2 owners have exactly the same problem.
I all cases it seems to be the router's firmware, that causes this problem. I found two users reporting, that the only solution was to download a new firmware from ...
http://dd-wrt.com
But maybe it helps to drop the speed from 802.11 N to G?

I have the exact same problem and my firmwire on my router is the latest. What I do to fix this problem is just unplug my router and plug it back in. I find that fixes it for me. Post back if that doesn't work

That's why two guys reported, that they had to download a new FW from DD-WRT, which solved the problem for them.
Sorry, that I don't post links ... it were german forums.

I have the exact same problem. You say that the other two S2's work perfectly? If that's the case then it must be a hardware fault. I'm gonna take mine to be fixed or replaced.

Likely ... maybe different firmware?

Yes....my SGS2 and my brothers work fine. When I update....I update all 3 so we are all using the same firmware.
Thats why I believe its a problem specific to 1 phone....not the router (although I did update my router to latest firmware just in case.....same problem)
As a side note - my brother has a microphone echo problem when using a specific gel case. When my wife and I use the exact same case - no problem. I dont know how Samsung build their phones - but its not very consistent.

That's why we have a thread about the "Made in ..."
But that's not only a Samsung problem ... I know that from the Asus Transformer forum.

Ill see where our phones are made if I have time. If anything though, my brother should be the odd 1 out as his was bought in Australia whereas I got the other 2 from UK.
Ill get to the bottom of this....even if I have to keep doing hard reset and trial and error tests. Not being able to use wifi is a huge deal.

Just to confirm, the problem's not only apparent in 2.3.4. My phone has the same problem with 2.3.3. I've sent my phone in for repair now so i'll post my findings here in a week or so. Have you got any further with it?

I sure hope they do fix it somehow....It's becoming increasingly annoying having to flick wifi on and off, downloading apps is the worst. This never happened on mine or my girlfriends htc's.

Anyone able to find a solution for this problem? Just picked up my Galaxy S2 and have the exact same issue Wifi connects, surf the net for about 10 sec, then nothing.. still connected to Wifi and everything.
At work at the moment so can't really play around with the router settings but will try once I get home. Have been looking forward to getting this phone for a while now and to have Wifi issues right off the bat is quite disappointing..

wifi connected no data flow
i had the same problem
i tried different ways no sucess
i tried Set DNS Pro from market
tried different settings
applied different dns
shift from open , custom to google ang keep checking the internet in browser
after few try it works everytime
its to do with assigning ip address in android
thanks

I posted a solution a few weeks back....but i think most people overlooked it....so the solution is
Go to settings>>>>wireless and networks>>>>>wifi settings>>>>hit menu and go to advanced>>>>regulatory domain>>>>change the channel to 14.....thts it....it worked for me on vibrant,nexus one and even on sgs2..hope this helps

Channel 14 is not allowed in most countries ... my german router e.g. doesn't have channel 14, only 1-13.
I had similar issues with my Asus Transformer and found out, that a static IP works best, BUT only if a secondary DNS is assigned too. I used Google's 8.8.8.8
Give it a try. The Broadcom drivers seem to have a bug, when no secondary DNS is assigned.

The "regulatory domain" setting isn't there on my galaxy s2 ;/ Will give the static IP solution a try.

[Q] Package File is Invalid - No mentioned fixes working for me

I got my Nexus 4 today, and I've been pretty excited since.. So far, it's worked flawlessly everywhere except for when I need to download something from the play store.
Almost every download results in "Package File is Invalid"
I googled for hours, literally. I wiped data/cache of Google Play Store, Services Framework, wiped Cache from the stock recovery, and even factory resetted the phone to no avail.
I'm guessing it's a problem with my home's router setting. Everything works fine on my nexus except for the play store. Haven't gotten a chance to mess with other wifis yet, but can anyone tell me a way of fixing it?
If it doesn't work by tomorrow, I might run a custom ROM and try, though I really wanna stick with stock till 4.3/5.0 comes out :\
Any help?

Login to the Playstore from a PC and make sure your N4 is listed on your account. Also, try and install an app on your phone from there.

What happens if you try to install an app with Wi-Fi off (Mobile Data)? This could rule out an issue with your router or ISP.

It works fine on 3G for me. It's not a ROM issue since I tried it on stock, PA, and now CM10.1.
However, very small apps download without issues. I think the cap is around 5 mb above which the error shows up.
I'm 100% sure it's my router's settings that seem to be working against the nexus. Any idea what I could do?
I absolutely LOVE the fluidity of this phone (coming from a single core phone running a buggy JB rom) but this is killing me!!
The worst thing is, all the workarounds that I've read about since yesterday work for few, but not all people. And there are lots of workarounds. I've tried all that I've read but nothing's working :\

What router (Make / Model) is it?
Check for a router firmware update. If there are no updates or support, check if it is supported by DD-WRT.
Try doing a factory reset on the router, then set the security settings to (WPA2 only / AES only) and use the Android app WiFi Analyzer to find the best channel.

It's a DLink router.. No updates available
I reset it yesterday and put WPA2 but it hasn't solved the problem still :\
Wifi analyzer told me channel 6 onwards were good, so I tried 6 and 7 but didn't help either
I've had to download apk's for all the free apps to make it work as of now
I'll check with my mom and dad's phone to see if this problem exists for them too, but they're running gingerbread so idk if it'll mean much even if it works

First I would return to stock ROM. A custom ROM could have it's own WiFi issues.
As for the router, the only other suggestions I can make are;
test it in unsecured mode (open Wi-Fi access)
force 802.11G (disable B and N access)
lower the MTU from 1500 to 1480
disable uPnP
disable (or enable) WMM support.
disable any content filtering (like blocking java, proxies, etc).
Changing these options one at a time and see if any one fixes your issue.

Use VPN
Has been occurring a lot lately. Well, not a fancy fix but a simple one ..... use hotspot shield to connect and then all files install normally over wifi. Don't know why it does, but it works!

I have had "package file is invalid" issues with my Nexus 4 and my home WiFi connection from day 1 of owning a Nexus 4. I have tested it on 4 different WiFi Routers with different firmwares including stock and DD-WRT.
- Linksys WRT320N Dual Band (With Stock and DD-WRT Firmware).
- Linksys WRT160N V3. (Stock and DD-WRT)
- Tenda N60. (Stock "2012-12-12 V1.0.0.16_EN" and newer variants).
- ASUS RT-N66U "Dark Knight".
Tested 2.4ghz and 5ghz, varrious combinations of WEP,WPA-PSK, WPA2-PSK, WPA2-AES. It makes no difference the ONLY router from the above 4 that works correctly when downloading over WiFi from the Play Store is the Tenda N60 using the early release stock firmware "2012-12-12 V1.0.0.16_EN" that the router is shipped with. Even with the Tenda N60 if yuo upgrade the firmware to newer releases of stock firmware it will cause the issue to return.
Now this is an issue specific to the Nexus 4, I also have a Nexus 7, Samsung Galaxy S3, HTC Desire, Huawei Ascend G300. None of these devices have this issue using any of the router or firmware revisions. i.e: I can download from Google Play over the same WiFi connection with no problems.
I have had my Nexus 4 swapped for a replacment and the issue remains. So I've come to the conclusion that it's defintiely device specific the Nexus 4 has something inherently wrong with it..whether it's WiFi Drivers, Android Kernel, WiFi Chipset I dont know.
It doesnt affect all WiFi conenctions I can use my WiFi connectiona t work and the issue doesnt occur. It's strange that the cheapest router of the 4 I ahve tested i.e: The Tenda N60 is the only one that works consitently, I have never seen the "package file is invalid" issue using this router and Tenda firmware "2012-12-12 V1.0.0.16_EN".
This basically rules out any ISP, or WiFi security settingas as I used the same SSID, Security types and Network Key on the Tenda as the other 3 routers..
Poor show by Google, they obviously dont care about fixing this issue.

So your router having an issue is a Google problem? Well done coming to that conclusion...
For what it's worth, I have no such issues with my home router (Thomson) or my work WiFi network (no idea what router we have here but it's probably a Linksys/Cisco jobby)

Ermm...you might want to read that last post again, 4 different routers from different manufactuirers with different WiFi Chipsets (Linksys x 2, Tenda, ASUS) tested with stock and 3rd party firmwares all exhibit the same issue with the Nexus 4. Where as NO other android device or any other WiFi device on my network including a Nexus 7 with the same version android version as my Nexus 4 (4.2.2 ), connected via the same routers have any issues, even side by side downloading the same app from the Play store at the same time the others will suceed the Nexus 4 will fail the download "package file is invlalid" which sounds like a data corrption issue.
Co-incdecne thats it's only the Nexus 4 that has these issues ? I highly doubt 4 different routers are all faulty...especially since it's only the Nexus 4 that has this issue.
If you check the google code pages you'll find several other people complaining of the same issue.

All I'm saying is the 2 routers I use most have no issues and neither does the one my parents, my local pub or any of my friends. Might be a UK thing, I don't know, but I've never had a problem on WiFi at all...

I agree with that, maybe it's even a particular hardware batch of N4's, not sure. I can use my N4 fine on my work WiFi and other locations. Like I said it does work on my home WiFi if I use The Tenda N60 router with it's early release stock firmware, any firmware upgrades cause the problem to return though. But it cant be right that you should have to use a specific router and specific firmware which you cant upgrade without breaking the N4.
I've got another support case open with Google Play which they've apparently passed to their techs, lets see what they come back with... I have heard of someone with this issue using a custom ROM with a different Kernel to the Google stock build which includes newer Qualcomm Prima WiFi drivers (Paranoid Android) , they claim this fixes the issue for them.
Im relectant to flash a custom ROM and void warranty though for a basic feature that should work out of the box though.

I tried a lot of different things but nothing seems to have worked sadly.. I'm gonna update my ROM tomorrow to CM10RC4 and see if that helps, though I doubt it's the ROM's fault. Btw, I had the same issue with the stock ROM too

I've been having this problem whenever my portable wifi device connects to a slow mobile network. All my friends connect to my hotspot, but only my Nexus 4 gets the "Package file is invalid." error. For months, I've had to contend with switching to mobile data just to finish my downloads.
My only conclusion is that the Nexus 4 has a problem with slow connections over wifi by corrupting the data transmitted. It's fine when using mobile data.

Check this out:
http://forum.xda-developers.com/showthread.php?t=2300873
It requires the phone to be rooted. I'm already testing it out now.

I cant verify 100% yet but my Nexus 4 took the Android 4.3 OTA update yesterday. I have since tried several WiFi downloads over WiFI from the Google Play store and not a single one has failed !
So my intitial thoughts are that the Android 4.3 update has recolved this issue..and it was indeed a bug/fault in the previous versions maybe it's the new kernel, Qualcomm Prima WiFi drivers, New Google Play app... But whatever it is. It seems to have fixed the issue. Well done Google about time too !
The only down point is the denial of any issue their end from Google Play staff and blatant lies they tell customers about not knowing about such bugs.

Ironically, the 4.3 update on my Nexus 4 yesterday actually seemed to trigger the Package File is Invalid error, as it wasn't a problem before. MX Player and Jetpack Joyride are triggering this for me atm. Anyone else still have this on Android 4.3?

Having the same issues on all of my devices, but only while trying to download on my home wi-fi. Like the OP said, anything over 5mb won't download. Droid Razr M, Droid Razr HD, Note 10.1, Tab 2 10.1, and Nexus 7 (running 4.3), I cannot figure out what changed on my Belkin router (AC900) to cause this to happen suddenly. It was just noticed last night, and I have spent hours today trying to find a fix, and creating more problems to fix. If anyone has any step by step instructions of how to fix this, please explain to me like you would a 6 year old. BTW, rooting is not an option of all of these devices, so please make it a root free option. And I have cleared all caches/datas and done all the force stops recommended, as well as removed the google accounts and readded them.

Galaxy S8 WiFi issues after Oreo update

Hi,
I just received the Oreo update for my S8 and everything seemed fine from the start. It didnt take long though when
I noticed that the WiFi was acting weird. Even though I had great connection to my modem, my WiFi performance
was extremely poor. The two arrows beside the WiFi logo in the status bar only showed upload and no download when I
tried to open a website. I tried forgeting the network but it only seemed to work momentarily. So I rebooted my modem and
hoped that it would solve the problem. Rebooting the modem only worked momentarily too. I will be checking later if this issue
continues with other WiFi networks.
Has anyone else experienced this?

Same problem with My S8 after Oreo. Occasionally the !-mark next to wifi-symbol and the connecton is lost. By restarting the wifi-router or renewing the wifi connection from the phone fixes this for some time, until it happens again.

This fixed it for me
Mine was doing the same but noticed I could stay connected to a older router I use as an extender so changed my wifi security on my main router from wpa2-aes to the older wpa and it's been fine ever since stays connected on 2.4 and 5 now

Is there a fix for this yet? I just downloaded the newest update they rolled out today, 4/3/2018 and I still cannot send email if I am connected to my wifi. It tells me "couldn't send" and it sits there until I turn off my wifi and use my data. This is ridiculous. My wifi connection is fine. I should not have to turn off wifi every time I want to send an email. So frustrated. Why roll out another update so quickly if not to fix the issues the March update caused????

I am also a an S8 user and noticed my wifi dropping connections throughout the day and reconnecting. This has occurred ever since Oreo update. I have tried all the possible fixes and none of them seem to work. I have sent my phone to Samsung for a repair and they have useless approved centres that lie about fixing the phone. I have sent it back. Lets see what happens. Worst case scenario I will have to install Nougat as it was working fine on this version.

Same here ! =(

Same problem
Sporadic exclamation mark on the WiFi icon
and poor performance .
Opened another thread on too many open ports.
Used sockstat and too many ports are listening.

Me too

Did you guys notice this after the Oreo update or on Nougat as well?

I’m having this problem since the Oreo update too. I have to turn the WiFi off and on several times a day to fix it. When attempting to use WiFi, no pages etc will load and then eventually a ! Symbol appears next to the WiFi icon. Only fix is to turn WiFi on and off. It’s very annoying!

Exact same issue. Started occurring right after oreo update

Have you guys complained to Samsung about this? as making noise to them will rectify your faults eventually.

Same here, WiFi unreliable since Oreo. I need to restart the network to make a WiFi call and that isn't always a reliable fix. I started a chat with T-Mob on FB and gave up. They're clueless. Samsung S8+

Hello same issu, I'm from France an online the forum in France an Germany many people have this problem.

I read somewhere to delete the wireless connection from your device and then re-add. I'm not ready to say it fixed things but the WiFi does seem more stable.
UPDATE - Sorry to say there are still issues. Oh well, it gave me hope for a brief moment!

Go to settings- General management- Reset- Reset network settings- Then confirm and restart the phone. After re add your wifi networks. That fixed it for me
Update: It turned out that it didn't work for me... it looks like i may have to try and factory reset as it feels like i have tried everything else :crying:

T-Mobile just had be clear the cache from the "boot level" menus. Let me see if that fixes anything before trying yet something further. THANKS!
PS - clearing the cache did fix the problem I was having with the TX Lottery app. After the OREO update it would no longer scan the ticket barcodes. It's working again!
