GT-P3113 Wifi Issues

I have a Galaxy Tab 2 7.0, model number GT-P3113, running Android JB 4.1.1 stock ROM. It is rooted.
Also: Since I am new, I can't post any links.
Due to accidentally deleting the Google Play store (yes, that was stupid), I decided to factory reset my tablet. Once I factory reset, it would not connect to any Wifi networks. It would attempt to connect to the network, say "Obtaining IP address..." and then display an error saying "Network disabled. Poor connection". It did this for every network I tried to connect to, including the ones at home.
Some things I did prior to the factory reset (I don't know if this makes any difference as I'm new to Android)
The Galaxy Tab 2 originally came with Android 4.0.1, but was upgraded to 4.1.1
Was rooted with CF-Auto-Root-espressowifi-espressowifiue-gtp3113.tar.md5
BusyBox installed. (from BusyBox installer by Stephen Stericson)
Some things I already tried (and obviously didn't work)
Clearing the /data/misc/dhcp folder
WiFix Manager, it crashed when I tried to use it. (app on Google Play store)
Wifi Codes, no longer on Google Play store to my knowledge.
Already checked router, firewall, etc. at home, found no problems to my knowledge.
Factory reset again.
Forgetting the commonly used networks and re-entering the password.
Forgetting the commonly used networks and adding the network manually.
I've seen this post already, please don't respond with a copy-paste of this list.

may sound crazy but try resetting the wireless router. sometimes after flashing a new ROM I have trouble connecting to wifi and resetting the router (even though my laptop, cell phone, brothers cellphone all connect fine) and bang it works.

Thank you for taking the time to reply. However, I have tried this, and it didn't work. Anyone else have a fix?

Thanks for the advice. I'll try it.

Same issue on stock 4.1.2 . Just purchased the tab 2 days ago

[Q] WiFi hotspot connects to other machines, but provides no data.

Hi:
I recently moved an unlocked phone to a new carrier (Virgin Mobile, Canada).
The WiFi hotspot connects fine to other (Win7/Win8) machines, but no data gets through.
USB tethering works as it should as do all the on phone internet data functions I have tried.
I have looked at all the setting I can find values for in the APN menu, thanks to another poster in this forum) but all seem correct. The hotspot setup itself has not changed from the, previously, working one.
Tech support at both the carrier and the phone manufacturer are not able to help and now are pointing to the other side so I am on my own at this point.
Any ideas?

That is the problem in android. Somethings "something" will change, causing it to malfunction. I have seen a loot of those problems, even in real life and here on xda. I recomend if you have custom recovery to do a full wipe, and if you are willing to, install a custom rom.

[Q] No Data and Wifi data transfer (but connected))

Hi guys,
I'm using moto g for about 2 weeks and everything was fine until yesterday. I will try to explain what I've chronologically. My phone isn't rooted. Android 4.4.2, 174.44.9.falcon_umta.Retail.en.GB, KLB20.9-1.10-1.9
For last few days I was testing some battery stretching apps, such as Juice Defender, 2x Battery, GreenPower and maybe one more, but I don't remember the name.Finally I've bought Juice Defender Plus as that app was something that I needed (control mobile and wifi in an intelligent way, but that's not the point). Before JD I've uninstalled other battery aps (but without reverting their settings to defaults). Then I've installed JD, configured it and started to learn JD with my wifi network, whatever.
Next day I went to work and I'm not sure if mobile network was working or not, but wifi network was ok. Updates, synch, etc. was working well. I've installed 2-3 new apps (don't remember, but it was camera360, total commander with few plugins, and maybe something more). Then I've left wifi network, entered car and connected with mobile network. From this point everything stopped to work. There was no connection to any site, no synch from google, weather, and so on. Icon on top of the screen informed me that connection is online (with H or H+, sometimes worse, but probably it doesn't matter). I've tried to connect with many apps to Internet, but none of them succeeded... I thought that maybe there is something wrong with mobile and after that, when I get back to wifi coverage, everything will rise and shine.
Unfortunately when I get back to wifi zone, phone found new network and connected to it. It doesn't matter what network it is, because few days ago I was working with that wifi net and more on that, laptop connected to that network works like a charm. As I said, connected, data transfer in 3g watchdog shows very little net usage (about 200-300B/s). Can't load web pages, can't sync. The same behavior as in mobile, there is connection, very little data usage, but nothing more, no web pages, no sync, etc..
I've restarted phone many times, entered in airplane mode, removed, cleaned and inserted back the sim card - none helped. I've checked ip, gateway and dns which came from dhcp router in wifi network. Everything was fine, addresses were the "same" as my laptop (beside ip address, which was different). I've checked what's up with JD, then I've disabled it, uninstalled..., checked transfer limit for mobile, turned on and off mobile, wifi in many ways. Checked proxy in browser (chrome).
The result was always the SAME.
in chrome: entered address, page starts to load, nothing shows and stalls, after a little while (tens of seconds) there was a message telling me something like: page is unavailable (I can't remember the right message).
in gmail: sync lasts forever, when I send email (to myself) it popups message about sending, but it disappears in a while, a no new email...
other apps, for example, weather on main screen, sync could last to eternity, and no new data.
Today, after whole day without wifi coverage I went back to wifi zone and tried to connect to it... and all emails, sync, whatsup and so on, updated. I think that, I didn't change nothing, but why wifi started to work? I don't know.
I've checked if mobile Internet works as it should, but without any positive results. In mobile there is the same problem as for a last 2 days...
Does someone know any solution to my problem?
PS: I've even tried to enter ip address of wp.pl host, and then phone redirected me to address: 194.9.223.70/ns/cs/deny.html?trx=...something&tpd=3&ts=somenumber&sid=HTTP_DRSTD&url=...mobile[dot]orange[dot]pl

Are you able to send & receive calls? Have you checked your APN as well? Wondering if one of the apps you've tried has changed a setting or set itself as some kind of proxy that your phone's still trying to use even though you've uninstalled it.....not sure......had a similar experience when I tried out a firewall app & removed it without disabling the settings it applied. Can't think of anything else, sorry mate

Yes, sms and calls works fine. APN is okey, moment ago I've sent configuration sms for internet apn from my operator. I know that it could be one of my apps, which I've uninstalled, but I don' know which one it was .

Might be worth checking device administrators in settings as well just in case the culprits there? Good luck

Checked that, there is only Android device manager (sorry, maybe there is another translation, I'm not using EN lang in my phone) enabled. The rest dev admins are disabled.

Factory reset. That way you start from scratch and if still a problem you can rule out any apps or incorrect config etc. Its the easiest way to narrow down the issue.

maybe it's the easiest way, but I think it's not an option if I want to know what was wrong...

Sounds like one of the apps is the problem, as you already suspect. You may have to concede and do a factory reset:
Settings > Backup & reset > Factory data reset​

Please make some effort... factory reset is not the first thing to do when sth is wrong.

I suggested a factory reset as this then rules out all apps and config you have setup. If the problem still happens after a factory reset then you have narrowed down the problem a lot. Possibly it will just fix it though.
However if you want to find the cause of the issue then factory resetting is not the best thing to do as you say. But you seem to have installed a whole bunch of apps in a short space of time so even if you find the problem I doubt you will be able to find out why it happened, ie which app caused it.
You will maybe fix it but never know what caused it or how to prevent it again.
If you factory reset and it fixes it you can take things more slowly this time, is install apps and configure more slowly until you hit the problem, then its easier to see what caused it.

As there was no chance to get other suggestions than "do factory reset" , I've made factory default. Unfortunately, without any change in my problem. Right now wifi works fine, but 3g/data is dead. I've checked my sim card in another phone and 3g/data didn't work too. So I've called to my telco and heard that everything is ok, but probably my sim card is damaged and that's why my data connection is dead. I will try to get new sim card tomorrow.

So those of us suggesting a factory reset were correct then. Had you not reset you would have spent wasted time trying to fix what now appears to be a sim card error. Possibly best not to tell people to 'make an effort' when they are trying to help.

Wifi problem - on-off and no wifi hotspot, phone restarting - Please HELP

Hello everyone,
me and my wife enjoy our htc U11, but few days ago mine start playing up - wifi have difficulties to connect its doing like on-off-on-off, and after while connect to router, doing same thing at work and home too, and I really can't use any longer wifi hotspot, and phone restart at least once a day, not very happy, but today my wife experienced same problems as I have few days, must say both phones bought in UK from two different companies and different times, both are on stock rom, completely standard phones, I am only using modified camera apk, can anyone give me advice what it could be?, I do not have even Facebook or Twitter account, so can't be related to these apks. Was going to do hard reset tonight, but after my wife told me she got same problems and she use her phone very little, I am not sure if hard reset will resolve problems. I will welcome any help...
Forgot to say we are on 2.33.401.10
Many thanks..

Settings>more>data usage>network restrictions>check to see if the network has been restricted.
Settings>more>three dots (overflow menu) and hit "reset network settings"
Have you reset the router, checked the network settings are correct (if you use dhcp just reset your router).
If the ssid has spaces or characters/symbols then this can cause issues.
I have personally known routers that use signal binding to run at speeds incompatible with some devices. Especially those with 1gb interfaces. *cough netgear*.. Falling back to a basic setup helps significantly.
A factory reset will probably solve it but you'll lose your data. That is the last ditch effort.

Hi, what is latest update for this rom?, as we can get no ota update, if you point me right direction, will be great, and I will update at least one phone, and see difference. I already reset home router, I reset network setup on phones, wipe cache on both phones, still problems, and even when I am not at home, wifi playing, as I can setup wifi hotspot and I am away from any wifi. Many thanks..

Sorry that was my bad, I forgot I was looking at my m9, not my U11. You are up to date.
My post has been edited. Follow that.
To have the same problem on both phones is very strange indeed. It must be network settings causing the problem unless you have an app running that monitors WiFi in some way..

I, too, have been having WiFi problems all of a sudden. I am not stock, I'm on viper with EAS kernel, but was running it all just fine for a while then without changing anything, I have the same problem.

Still looking for fix, but no luck so far, tonight I reset router just to be sure, but problem is still there, I am sure sooner or later I will find out what is behind this problem.

Mobile network internet access stopped working

Yesterday was like any other day, I took the bus to work and enabled mobile hotspot on my Oneplus 6 so I could do some work. On my way home in the afternoon, I did the same thing. This time however, I had exclemation marks on the mobile network symbol in the statusbar. Tried enabling hotspot anyway but there was network. Rebooted the phone but still the same issue. Oh well, I thought it was just my carrier then. When I came home to my wifi, I checked my carriers status information on their websites and there was no disturbances. Then I restored a backup which failed and I had to reflash the phone entirely with the latest pie zip. Today, I still don't have any network on my sims. I use two sims but they are using the same carrier. I also asked around my friends which has the same carrier and they have network...
I would understand if something might have happened when I reflashed the phone last night but that does not explain the sudden malfunction of the network on my bus ride home, the phone had worked flawlessly for a whole week.
This thread seem to be about the same thing and I tried the solutions regarding clearing caches and settings but it did not work:
https://forums.oneplus.com/threads/...ot-working-but-network-bars-are-there.844978/
Could it be something with the IMEI number? But it doesn't explain why it stopped working out of the blue. I can see both my IMEI numbers in the settings and I have also tried install Magisk 17.2 beta as suggested by another user. I think I still have a backup of the modem on my pc. However this is from when the network still worked and then suddenly stopped working.
TLDR: I have full reception, Calls and SMS work, there is just no Internet connection.

Just to be sure, datasave is turned off?

Yep, that is off. I have also reset my APN setting and double checked them with my provider, it didn't help.

No hotspot
I'm having a similar issue, I updated to android p stable and since then I can't use hotspot. It turns on fine and says devices connected but internet doesn't work on the connected devices. This seems to be an issue with Android P because my gf also has the op6 and I tried hotspot on hers before updating and it worked fine, then updated and it stopped working for her too. I have also tried clearing cache and manually entering the APN. I need to be able to tether to my laptop and tablet for work so anyone solution to this problem would be highly appreciated.
Thanks.

Although the problem I decribed in this thread isn't the hotspot problem, it was caused by my carrier. But I also have issues with hotspot, my laptop has trouble finding the wifi from the phone.
