[Q] WiFi connection issue after updating p3100 to ICS 4.0.4 ?

I have trouble connecting to WiFi networks (once in 5 iteration) after updating p3100 to ICS 4.0.4. If the problem surfaces, I have to turnoff and turn-on the WiFi couple of times to make it work again.
I have seen this issue consistently with multiple WiFi network with different configurations (WPA, 802.1x, without security).
I am considering downgrading to ICS 4.0.3. Or could this be a hardware issue in my tablet ?
Suggestions please.

My tab 2 (P3100 on 4.0.4 via OTA) have similar behavior sometimes it will connect but other times it just shows connecting until i turn it off and on several times.
But one thing I notice this thing happens when I try to connect to my home router which use 'n' networks while using my mobile 3g router (b/g) it connects easily (that I've tried currently). Does your wifi networks use 802.11n or b/g?

I have the same issue with 4.0.3.I hope it is not hardware related.

My home router supports 'n'. But i have configured it to work only on b&g.
In my case I see this issue with b&g setup as well.

I have been chatting with 3 Samsung agents and none of them are able to fix my tabs,they just want me to fill out the service request form,give me a break,I received the tablets today. What a joke.

I have an interesting find.
Instead of just turning WiFi off and on, if you do 'forget SSID->WiFi off-WiFi on->Connect" there is no connection issue at all and it connects every time without any issue. Which makes me believe that it is a software issue.
I have got another update last week (P3100DDBLF3) and I am disappointed to see the issue exists yet.

Removing the SIM card and doing a factory reset will wipe out this issue.
But then again put your SIM card back and try to connect disconnect your WiFi, There you got the problem again
This looks more like WiFi, GSM-Nework co-existence issue. Samsung .......:cyclops:

I reckon that recently samsung re-deploy 4.0.4 update for gt-p3100 and its variant. Does it still have this issue?

i dont think it is because of the hardware. ive used to had this problem. since ive updated my device to 4.1.1 jelly bean. it works fine. connected to the wifi almost immediately after i push the button

do you have wifi issues with 4.1.2?

Is anyone having wifi problems when connecting to a wifi network using 4.1.2?on 4.1.1 and below, wifi always worked perfectly. But it has been kinda broken with every 4.1.2 rom i have tried. Am i the only one?i see a lot of people complaining about wifi issues with 4.1.2 but i see no one mentioning this on our device.
what happens with me is that the phone stays in state "obtaining ip adress" for a long time and then proceeds to properly connect. The "avoid poor connections" option is not enabled. anyone know why this is happening?Also, the signal is worse than with previous android versions!

I've had that, happens only with certain routers and never really knew why. Also happened on GB though AFAIK.

but i have the same router as before and it also happens with my university wifi(and it didnt happen on 4.1.1 and below)! Never had any issues(ever!) with GB, ICS and early JB=/. But for some reason this 4.1.2 messes my wifi.
here is a logcat i took. as you can see the wifi "stuff" begins and then stops. Only after 30 seconds or so it displays the message that the phone is now connected

This could be a rom specific problem or even simply a kernel issue.

not a rom specific problem and also not a kernel issue. Have tried several roms and many different kernels!

Had this issue. Sometimes it doesn't even detect my wifi. Had to reboot the router for it to work. I think this is android-specific on SOME routers.

i always detect wifi networks. rebooting router does not fix this. Also, it makes no sense that it is related to the router since it happens with both my home wifi and my university wifi (and with 4.1.1 and below it worked properly on both my home wifi and university).
Some change must have been made in 4.1.2 for the wifi to behave this way. Anyone can get anything from the logcat i provided?
Also, the wifi connects properly if i set static ip on my phone but i can only do that at home because i have acess to my router. Is there any way i can restore wifi files from 4.1.1 to 4.1.2 to make it work properly without having to set static ip?

Same issue here

[SOLVED] P6200 XXMC3 Official JB 4.1.2 WiFi problem

Hi there
P6200 WiFi+3G
So I installed the new official release for Open Austria JB 4.1.2 but I am having a BIG annoying problem with WiFi :/
I tried to connect to my router which is WPA2/PSK secured but it just doesn't wanna connect! stuck on connecting then "saved" and nothing happens!
I've tried everything and every method:
wipe data/factory reset
re-flash
rebooting both my router and the tablet
changing my router's security to WPA,WEP and OPEN
It used to work just fine with Aorth's port of CyanogenMod 10 but I wanna use the official release!
Any help appreciated, thank you
P.S: I solved the issue by ignoring the feature and using this workaround found HERE

my wifi is working fine
maybe at one time i also had the same problem. i restarted my router and it was solved. now it is working fine.

Maybe country code is not set correctly , was a problem with me before, malaysian tab in US, search WiFix manager in PlayStore. Also wifi Connection Manager free by roamingsoft is a good app to get you connected and stay connected.
Also check your router to make sure you are on a channel that not many other people are, for less interference. Good luck. Wifi has been working without issues for me on JB.

I tried both apps but unfortunately it still doesn't wanna connect :/

I think that the only possible solution to get the wifi drivers from HC 3.2 stock rom or from any other p6200 working rom.
If someone could help me with that, I would really appreciate it

if wifispot is not visible then try to change chanel on router i had similar problem on stock ics only chanels 1-6 was visible idk

I have tried to change the channel to 11 and also changed SSID to a short one but still same results.
I have got this message too: "authentication error occurred"
The weird thing that when I made my network set to OPEN, I got this message!

I wouldn't expect everything to work for the US when you install a European ROM release like the XXMC3

I am actually from Egypt ^^
and the annoying thing when I had XXMC3 that WiFi was connecting just fine with other networks but not my own!

I too have the same problem !!!
The European version is JB is the XXMC3, .... but I'm in Italy! and the wifi does not work, and it worked perfectly with ICS.
I think the problem is similar to that of the Galaxy Note 2, but I do not know comne solve it.
I tried to do all the wipe, but nothing to do. Can anyone help me?

same problem here works with SOME routers but mostly it just says "saved, secured" or just authentication problem on open wifi
tried format / factory setting, reflash nothing works
had the same problem with 4.0.4 but it went away for some reason after a while

I have same problem

I have same problem with My Galaxy Tab P6200.
When I connect to a fine wifi : "type password -> authentication -> obtaining ip address -> Connected"
With my wifi when I typed password it's say: "saved, secured" and no wifi icon.
I have an ADSL router and connect to wifi router, wifi router like a bridge network, so DHCP in wifi router is disabled.

sounds like a UK vs US problem in the setup on your device. Try changing the wireless AP channel to channel 1 or 2 and see if that fixes it. If so, that is the problem. In UK mode, it won;t see wireless channels above 6

have experienced the same problem before, problem not with your tab but your router (something to do with router not able to automatically adjust or identify your tab after the upgrade and detecting a conflict), try going to your tab advanced wifi settings, select static i.p. address and input manually your tab i.p. hope this solves your problem

Im having the exact same problem that the OP had. Was a solution ever found, other than flashing another ROM? Id like to keep the factory JB but no wifi is a big problem. Any help would be greatly appreciated.
How do I change the channel on my router to 2? I havent tried that yet.

Wireless 802.1 EAP stuck at "obtaining IP address" on KitKat stock (can't connect)

Wireless 802.1 EAP stuck at "obtaining IP address" on KitKat stock (can't connect)
Hello everybody,
i know that it seems to be a common bug but i've found a lot of complaining about it but no solutions, so i hope i'm gonna be more lucky opening a more recent post.
I have a Nexus 4 and i was using Paranoid Android 3.99 (based on Jelly Bean 4.3) and then yesterday i decided to come back to Android AOSP stock in order to upgrade to KitKat 4.4.2.
I followed this procedure that is the official Google procedure, by the way.
I've wiped everything, including SD Card, and flashed every piece of the stock KitKat 4.4.2 for Nexus 4 (Android 4.4.2 KOT49H): boot, bootloader, flash, radio, system, userdata and recovery.
Now, i'm not able to connect to the wireless of my office that is protected with 802.1 EAP (PEAP + MSCHAPV2). The authentication is passed but then i get stuck at "obtaining IP address" and after a few attempts i receive the message "network disabled poor connection".
Once every 1000 attempts, i am able to connect successfully.
The signal is excellent, i'm really close to the access point.
I'm the only having this problem; we have a lot of Android phones and iPhones and they all work great.
I can't use a static IP address and i can't change the router/access point settings.
I have no problem with domestic wireless, protected with WPA or WPA2 PSK. I've tested 2 different wifi.
I had no problem with Jelly Bean AOSP stock or Paranoid.
Any suggestions?
Maybe a different radio?
I really don't want to wipe and flash everything back the second time in a couple of days. It's frustrating.
Thank you in advance.

By the way, i think i've found a workaround: the problem seems caused by the fact that the access point in my office transmits using both frequency 2.4 and 5 Ghz.
This bug seems to affect the 5 Ghz.
So i went to the menu Setting > Wi-Fi > Advanced > Wi-Fi frequency band and i've changed from "Automatic" to "Only 2.4 Ghz".
Noe everything's working fine with the office's wireless and every other network.

the employer blocked the WIFI from employees (obtaining the ip address issue)
we cant access the WIFI in the hotel at where we work and although there are a password you put at the hotel's WIFI website but they did something lately to all of us and it is when any of the staff open the WIFI on his mobile it just keep showing obtaining IP address and no result so if you guys could help me in this and do i have to get a new phone or to try hiding my IP i tried a lot of apps but no way plz help

Can't access WiFi at work since Marshmallow

So since I got the Marshmallow update on my Moto G (XT1540) I am unable to connect to the WiFi at work, I have the correct SSID and password and it worked fine on Lollipop, but keep getting "Authentication error" now that I have Marshmallow. I have tried doing a Forget Network and rejoining it and doing a Network Reset in the Backup and Reset settings menu.
Our internal help desk and myself are puzzled by it isn't working... We have a fairly current Ruckus WiFi deployment, using WPA2 and EAS encryption. This WiFi SSID is specifically intended for employee's mobile devices, and no one else has reported any issues, but to our IT staff's knowledge mine is the first Marshmallow device attempting to access the WiFi.
Any thoughts, or any way to track down what the real cause is? Would a logcat show me anything?

BUMP
Anyone else having issues with WiFi since Marshmallow? I only have this issue at this one site, always the same Authentication Error and I know it is not the password (on my company issued iPhone I have deleted and added the WiFi network several times, so the password is correct). Our help desk is stumped. I am assuming this is related to encryption type (TKIP/AES) from the error. This worked fine on Lollipop...

Were you able to resolve? I had no wifi issue until today. I am in the process of changing routers and just installed a Linksys 1900ACS. When connecting my phone to wifi, it gets stuck on "Obtaining IP address". However, when I try to connect to the guest network, there are no issues.
Update: I wanted to keep WEP to avoid changing the settings in all my wifi cameras. But when I changed to WPA2 Personal, all worked. Don't know why WEP did not work as it did with my previous router.

No, we were not able to find a solution other than I connected to the guest network, which oddly is on the same APs, using the same encryption, just a different SSID and passphrase, which works fine. Can't explain it or find a solution, sorry.
