[Q] suddenly Cannot connect wifi nor 3g - virus?? - Galaxy Tab Q&A, Help & Troubleshooting

Hi!
Somethig strange just happend... Grab my Samsung Galaxy Tab and noticed, that wifi was off... so i turned it on... it said scanning... and after 5 or 8 seconds wifi turned off by itself... tried again... turned off again...
so...
rebooting - no help...
what's going on??? help?
--------------
ok, factory reset helped.... but i'm still wondering.... was it a virus... does anyone know sth about it??

The word "virus" isn't really applicable to Android devices. If used in VERY broad terms it almost applies, but even then it's a stretch.
There are programs that do malicious things out there, and the best thing you can do to avoid that is check the permissions on everything you download.

I doubt it would have been a virus. There are a lot of other explanations. But, for peace of mind, search the market for AVG and download the free version. Personally, I think it is more often than not a source of false positives, but as I said, it can provide some peace of mind as well

Like...? Give me some ideas, please.

Well, I will say from the outset that I am not an expert at the technical details when it comes to such things. I would imagine that there was either some kind of corruption with the configuration files, or possibly with the OS itself. I have seen certain devices that occasionally reboot when power to WiFi is toggled on, for example. As to what caused it, there are really far too many possibilities to be able to say. I think that it would be difficult to get a virus from any of the app markets, most questionable stuff gets flagged. And of course you have the ability to see what these apps have access to. So perhaps it was an app that you allow network access to that screwed up the configuration through an error. Installing stuff that is non-market and of questionable repute could very well get you something malicious though.
Anyway, my original suggestion was going to be to try wiping all of the associated configurations and clearing the cache. But, you had already posted that you had it sorted out, so I didn't bother.
I am sure there are more informed people who could shed more precise light on the matter, these were just my ideas.

This does "just happen" sometimes. Usually, forgetting the connection information and re-entering it does the trick. If that doesn't then a hard reset (as you've already discovered) is the next best thing.

The technical term for what happened is "glitch".

PIE not working on 3G

Okay, I'm just wondering if there is a setting somewhere that I'm not aware of and hopefully someone could point it out. When I am at home and the phone is connected to my home Network ( WiFi ) Pocket Internet Explorer works just fine. Now turn off WiFi, reverting back to 3G, and Pocket Internet Explorer doesn't function. Just loads blank pages continually. The reason for me thinking it's a setting somewhere is because I also have Opera, which works fine on both WiFi and 3G. So while PIE is oblivious to the World around it, Opera's singing along. LOL! Honestly I wouldn't really even care except I have the mod installed that allows PIE to transfer live video streams to TCPMP thus making YouTube and such work rather well on the device. If that worked in Opera, PIE would never be used on my device. Hehe... So, anyway there's my problem. I eagerly await ideas. Thanks!
No one huh?
Geesh, I hate when I find a problem the technical like crowd can't even answer. :\ That leaves ya with... Technical Support from the... MAN... And we ALL know just how extremely useful / helpful those folks are.
Keep in mind that some people don't LIVE on this forum.. (i do though..) and the members of this forum are from all across the world, so people are on at different times.
Your posts are 13min. apart. If everyone could get their solution within 15min i think people that help out on this site should be paid! but thats not the case...
now to solve your problem; Are you on AT&T? if so i'd recommend finding the disablehiddenproxy.cab and installing that. I had the same probelm and after disabling the proxy everything was back to normal.
if i remember the manual correctly, for wifi you want proxy's off...
for MediaNet you want the proxy on

Firstly, thank you. I will try that.
Secondly, please check the dates of my posts. I realize that people do not live here. And all help is appreciated. I waited 24hrs.. And, by the way, I don't get to live here either. It is sheer coincidence that I happened to check back pretty much 24hrs. later on the button. LOL! Well, pretty close for not really even paying attention to that anyway.
Thirdly...
And thirdly, that is precisely why we all love ya! Disabling the proxy corrected the issue. I think that my phone actually came with that active, I don't recall PIE ever working over 3G... Until now that is. I figured it was simple since, as I said, I have Opera on the device also and it didn't care. It worked no matter how the device was connected to the 'net. Anyway, thanks much!

need some serious developer's input.

I need some input from serious developers, damageless, darch, gbhill, toast, etc. people who muck around in the real **** and have a deep understanding of the android operating system.
i have a hero that is no longer on the mobile network, and i want to turn it into a straight up PDA. i want to totally and completely remove anything that has to do with phone calls, mms, sms, and mobile network. ENTIRELY.
the only problem is that when i try to remove phone stuff from system/app, i get constant FC's until i nandroid restore.
how can i do this? anyone bored enough to try to help?
once again, i want to remove EVERY and ANYTHING that has to do with mobile networks and phone usage.
maybe wipe and just install debian? is this possible?
what can actually be DONE with this platform?
im looking for a discussion, some pointers of where to start learning, and some forward momentum on this.
thanks, guys.

You can install Debian, but it would be a pain to use and you'd have horrible battery life.
It would be easier taking something already stripped down, and stripping it down further.
I've been delving into this, and I have something working with no phone mms nothing.
I'll release something like this based off of Darch's build. It'll have a few issues, but it won't have any radio access to Sprint; just wifi.
You will want to look into an AOSP rom.. Since alot of htc's stuff all relies on one another. Alot of stuff is worked into htcs framework.
An aosp rom would be a good choice. And maybe just set airplane mode on so it doesnt connect to the network at all. This could be a temporary thing until something better comes along.

Once I upload it .
It's not much work. Just taking out the correct .apk's to ensure stability. And then adjusting some settings so that the radio never even turns on.
why would you need to do that anyway?
Why use the phone functions of a phone, If you don't have any service?
I think it's a great idea, I went 3 months using my hero has a pda using airplane mode and an app from the market that let me untethered wifi from airplane mode. Must say battery life was short of amazing but with a rom built for the very purpose I can see even more potential.
Thread Moved.

[Q] Internal Service Error - Lack of network....

Several months ago I installed CM10 on my Nook HD+ and for the most part everything runs perfectly.
However in mid March I installed a Cyanogen update and very soon after I noticed many of my apps (all downloaded from Amazons app of the day) would not run, giving me the following error:
Internal Service Error: An internal error occurred. This can be caused by a lack of network connectivity, please make sure you have a good network connection.
At the time, I Googled and tried the suggestions I found (although the suggestions were all for other devices such as Kindle Fire). I checked the time and date were correct, deregistered and reregistered my device and tried rebooting.
And that seemed to fix the issue, although I concede I havent been using the Nook much lately.
Tonight I went to use my Nook to play a few games and the problem is back and its even worse now. I now cannot play any of my games, even ones I have played numerous times before without any wifi turned on. We dont have wifi at home, I tether my phone when I want to use the internet on my Nook. I do know there are some games that require internet access, however the vast majority of mine dont, which I know for a fact as I've played them so often with no internet.
So, why all of a sudden, does everything need wifi? How can I fix this? Is it just coincidence the problem occurred immediately after a system update, and if it could be the update that caused it, how can I find out which update it was and can it be uninstalled?
The instances of this I found mentioned online mainly referred to it happening to just one app, and some people found uninstalling and reinstalling the app fixed the issue. But I have close to 200 apps all doing this.
Since I mainly use the Nook for playing these games, its useless to me as it is now and if I cant fix this issue I wont have any choice but to remove the Mod and return it to stock software, which I really dont want to have to do.
Please can someone help me with this, in basic, non-technical language please?
Thank you.
Hello?
Please, does anyone have any input on this problem? Have I asked in the wrong forum?
I asked about this in another forum and it was suggested that maybe the update made my Nook appear like a new device to Amazon and that the error message is the games wanting to confirm with Amazon that the license to run the game was correct (or something along those lines).
I have just tried uninstalling and reinstalling a couple of games and now they work so it would appear that suggestion is exactly what has happened. So I guess I now have to uninstall and redownload all those 200+ apps and games, which is going to be a nightmare with no internet at home.
And if updates cause the device to appear different, then how do I know this wont keep happening with future updates? I am not going to keep reinstalling every thing, so do I just turn updates off instead? That doesnt seem like a very wise idea.
I would really appreciate some help with this please, or even just to be pointed in the right direction if I should be asking elsewhere.
Thank you.
Well I guess no one has any advise or help of any kind to offer. I will post this update in case anyone else has the same issue.
I ended up having to uninstall and redownload every one of my apps, and now they all work fine again, so I can only assume the suggestion I received on a different forum that the update made my device appear as a new device, meaning the internet was needed for the apps to check licenses with Amazon was correct.
With this in mind, I would now never recommend the Cyanogen mod to any one else. Whats the point if updates are going to screw everything like this? I have now turned off the updates, which I would normally never do. When my Nook gets to the stage of having to have updates I will uninstall Cyanogen and just go back to using a stock Nook.
Its a shame as I have been very happy with it up until all this happened but since there is no back up or support from anyone when things go wrong, its simply not worth the hassle.

Work will supposedly start denying access to the wifi to rooted/jailbroken devices

So yeah, assuming their efforts is successful and they manage to set up their wifi to deny access to rooted devices, is there anyway around this without unrooting?

There used to be a module called Root Cloack(er) for Xposed frameworks that hides root, don`t know if there is a version for Marsmellow though. Its here on the XDA forums somewhere.
But how? I can't think of any way to detect a rooted/jailbroken phone from a Wifi connection, without you having to install or run some other piece of software/script that would give them that information.

I'm not sure. I would not put it past my company to make us install such a script in order to access wifi.
Many places are doing this. Detecting root is simple. Even Snapchat and others are doing it. Heck they are even looking for xposed and won't work if detected.
You would be amazed at what info people can get from your device when it's connected to wifi

a lot of info sure... But an app running on your phone detecting it, vs detecting that something is installed simply by connecting to their network? Your phone passes along a lot of info... but not installed binaries?
I could see them maybe having a black list, like if you're connecting the the exposed repositories your likely rooted... but if you are not using programs that require root access and communicate over the network, how are they doing this?

A simple request for the info. Have you ever looked at a logcat and saw everything running. I could be gone for weeks and come home and tell you every device that has ever connected to my network the whole time I was gone and with the right things in place could even tell if they are rooted or jailbroken
I can see the same as the poster above me on our network, it is not hard at all. And if we had such a policy and you used a cloaker I would have you fired.
Their network, their rules. I really don't think you should do this.

Can you provide any links or further detail? Obviously by viewing system logs you can tell whats running.... but I have never seen any standard network function to request a connected device to send logs without permission? Google searching the topic provides little info as its saturated with info on how to root, and using root for ad blocking.
Even a brief overview of the setup you would use to check? What are "the right things" and what "place" would the need to be in?

I wont get into it too deeply as I have my guys that watch this site as well and If they go around my security setup like with exchange pin request or using some devices on my network I will fire them on the spot. Lets just say the router logs everything that is done on the network. Connect your device to your wifi and then watch a logcat. You should be able to see what you are looking for.
Understand that unless approved by me no device can connect to my network. With the right router you can see everything about a device. you wont find much info on google as things like this are kept close to the chest with the IT crowd

No one here is trying to connect to your network. It's XDA and people are curious. I agree that it's silly to circumvent measures used by the company you work for (assuming you want to keep working there), but I also find it strange that you connect to a network and have that router, etc tell if your phone has a specific binary and apk. Is that what you are claiming happens?

This is not possible to limit an android version via network traffic, the best they could do is catch you updating cyanogenmod and ban your mac by guessing that your rooted, but its so much work, its a bunch of empty threats.

It can yes. And you are right this is XDA but you would be amazed at what info is not shared here or anywhere except between IT managers or other devs.
Once connected to a network it is not that hard to get everything from a device. This is why all the warnings about connecting to open networks. While Open networks are more of a risk it goes to show that anything can be done.
This has been a practice for a very long time even back to the WM days when roms encluded time bombs that would make the rom not work after a set time and date.

It's all smoke and mirrors to me until someone explains how it's possible to read files on a device by a user just connecting to a network and providing no further interaction. Sure you can get the device MAC, name, etc, but that's not how I read your statements. As mentioned in the post above yours, you can guess on network traffic, etc, but I really doubt anyone can "know everything".

Its not guessing network traffic. You can tell exactly what sites they go to. You can tell if they are using a mobile or desktop browser. (same way the carriers do it to prevent teethering)
All it takes is being connected to a network to be infected with a virus. Just how do you think that happens?
No one is gonna explain it. Just like we dont allow talks about network penetration. There are just something that are best not out in public view.
Here is an older example of how they detected jailbroken iphones on school networks.

I am specifically referring to detecting that a binary and an apk exist on a device SOLELY based on establishing a network connection (not viruses, not websites visited...user does nothing and no new code/software runs on the device). That does not seem probable to me.
It may just be semantics, but that's how I interpreted your original statement.
Of course network admins can see what sites users visit, what browser they use, etc and there is no guessing - only logs [emoji3]. I was using guessing in different sense (ie, you see something "suspicious" and draw conclusions).
Wow.... if i ever get fired after i found out they are 'reading' files on my device... this will be case for a courtn no doubt! I'm sure (at least where i live) the one that fires you based on such actions will have a big problem!

You would lose. When you agree to use their network you agree to all their rules. This is the main reason for things like Knox. As more and more place move to a "right to work" setup where they dont need a reason to fire you at all. I would be careful about what rules one does break. Gone are the days where we could get away with things like this.
You know this got me thinking. Maybe I will play around with my network and see what I can find out. I have to block root and xposed users anyway so this would be a great challenge. Might be awhile as I revert all my PC back to windows 7.
From an IT perspective, a rooted device provides little to no security. That's why most mobile device management (MDM) products include a feature that let IT block rooted devices from connecting to the secure network or accessing corporate assets. But these products must be able to detect rooted devices before they can block them, and there are ways users can get around those detection mechanisms. Organizations that rely on MDM alone to detect rooted devices should be aware of these limitations.

Trouble accessing specific site, regardless of browser of device (through hotspot)

Hey all - really scratching my head here. For the last two weeks, access to www.phantompilots.com has been really terrible for me *on my phone*, or any device connected through it's hotspot. Occasionally the site will work flawlessly for 30 seconds, but usually, each time I click a link, it will hang at 10% and take maybe 2-3 minutes to load fully, if at all. Nobody else on the site is having trouble, and if I use a different wifi connection, it works like a charm. This happens regardless of browser on my phone, my iPad, or my PC laptop. I called Verizon several times and they tried to reset a few things from their end, but none of it helped. They finally said "well, the internet is working on your phone, so beyond that we can't help you." They also knew my phone was rooted. They probably didn't know the bootloader was unlocked too
Anyway, I'm really grasping at straws here - anything buried in my phone that would be handicapping one specific site? Before two weeks ago it was working fine.
Many thanks in advance for the help!
Wanted to also mention that even when I go to click "like" on a forum post, often it takes 10 tries for even that to go through. Just like information is getting totally dropped...but every other site is fine. Thanks!
Do you have any kind of adblocker? (For instance, I use adaway.) If so, as an experiment, temporarily disable your adblocker.
Good idea, CM, but I actually don't. I experienced some strange things (not unlike this) when I had one, so I uninstalled. But it *is* acting similar to a problem caused by that - except it does let it through unfettered for brief spurts! So strange.
Hmm...well, now it appears there are others on the same site having the same problems! *Really* glad it's not just me! Which likely means it's on their end.
