[Q] WiFi connection issue after updating p3100 to ICS 4.0.4 ? - Galaxy Tab 2 Q&A, Help & Troubleshooting

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

Wifi has been working great for me. It reconnects automatically and doesn't drop. The signal seems on par with my nexus one.
Speed wise, is it on par with the 3G network?
[Q] Wifi does not work anymore after rooting :(
So, I unlocked my Android 2.3.1 and rooted it ... But if I click on wifi so I could connect to my modem it says Error and wont even search or anything. I tried reseting too but still no luck .. What is the problem and how to fix this ??
That's odd, I didn't have any issues with wifi as I connected to Android Market to downloaded ROM Manager during my rooting process earlier. Have you tried flashing a custom ROM on your device to see if it'll fix it?
No I didnt, would that work? .. A friend told me to install a new "kernel" but I dont want to overwhelm my android with custom made kernels .
your problem is you used one of the quick methods of rooting your phone, which used a kernel that wasn't from the exact rom you have.
if your on stock 2.3.1, you will need the stock 2.3.1 boot.img, and then you'll need to root it manually the long way via adb command line. search the nexus s development section for how-to's. they are all there.
i too had this problem, had to install MoDaCo ROM to fix it, but i dont regret rooting, i now have custom rom and over clocked cpu on the nexus s
you have two options, either to flash NANDROID backup to un-root and return to stock or install a custom ROM, i choose MoDaCo bcoz of its UI, it looks and feels just like the stock one.

Yes, that's the point of MoDaCo roms, to make minimal changes to the look and feel of the phone, but to improve performance with his custom optimizations.
[Q] Nexus S wifi issue. Unable to access wifi from my nexus s.
Hi Guys,
I was able to connect to my wifi network for a day. I am using windows 7 machine as hotspot with connectify. From second day I am unable to connect to any wifi network. I did factory reset my nexus s but no results . Can some one help me how to solve this issue?
Observations:
*when i use static ip, It shows connected but the bars are in white instead of green color and i am unable to browse.
*When i use dynamic ip I am unable to connect to wifi. It shows obtaining Ip and never connects.
*In connectify when I was able to connect to wifi the device is shown with an android device name. but now the device is shown as unknown.
Sorry for my bad english, I m not a native english speaker.
[Q] Nexus S Wifi Settings - force close
Hi all,
Just got a new Nexus S - all was well at home. Took it to work today and noticed something very odd. It was fine until entering the wifi settings menu - at which point it dramatically slowed down. I got two 'not responding,close or wait' messages before being able to join the network.... all other settings are fine - just the wifi area.
Weird - wondering what could cause this... too many wifi networks broadcasting (am in middle of London)...?
Anyone seen anything similar?

Too many WiFi around you shouldn't cause that.
Try rebooting and setting again if you haven't already.
Hmmm - rebooted and still have the same issue. At home, or even a block away from the office it all works fine. But in the office itself, although it connects and uses the wifi fine, the settings page is VERY slow to load and gives me the wait/force close message.
Out of interest - I also have 'wifi analyser' from the marketplace. This too is very slow and unresponsive when in the office.
So - it is definately something to do with the wifi here.... but have not got a clue what. Before I join the wifi, or when I am physically somewhere else it all works fine.
Wifi is WPA-TKIP, the key is a very long jumble of letters but surely that is not an issue.
Strange eh!!!

[Q] Possible WiFi problem?
Hi there, just bought a Nexus S, also used to have Nexus One.
The thing is for some wireless networks even though I enter the password correctly, it says connected and still there is no connection at all. (I mean browser tries to connect but at the end it says page could not be found) I even tried with an ad-hoc network that I created with my laptop but still the problem exists.
At home I'm able to my network without a problem. The type of network I'm trying to connect is: WPA2 Personal with AES. Is there any known issue about AES at Android system? Afaik there is no way to change the encryption used right?
this might actually not be a nexus S issue.
some modems/switches/routers are configured to block certain devices/applications/package's
we have a modem and router with both wifi.
but my psp/nDS cant connect to the modem,but can connect with the router

i have a similar problem. My Nexus S connects to my router only within a few hours after a router reset. Then it stucks at "obtaining ip" and never connected before I do another router reset.
My home wifi is WPA2 type, and for WEP type wifi my NS never got connected.

[Q] Wifi continuously authenticating

I just flashed to jelly bean 4.1.1 on my verizon GS3. I can't get wifi to stay connected. It continuously rotates between "Authenticating", and "Saved, Secured". Eventually it gives up and just says "Disconnected". Anybody else having that problem?

Probably wont help but try a different channel on your router. Change from "Auto" to something else. Are you using WPA2 security? Try removing the security settings (TEMPORARILY) as a test. Try resetting your router to factory defaults and set back up again.
In the end... sometimes certain routers appear to have connectivity issues.
My Netgear WNDR3400 can be very problematic

I've had my Verizon Galaxy s3 for about a month without any wifi connection problems - until yesterday. It worked with my old router (Linksys) and several other secured routers (when visiting friends) with no problems. I installed a new Netgear WNR2000 in my system after the Linksys developed problems. I had the "Authenticating - Saved, Secured" rotation problem as soon as I tried to connect. For lack of any other ideas, I tried all of the encryption codes available on the Netgear - one at a time. When I got to WEP, it worked perfectly.
I called Samsung. The tech I spoke with said the WMR2000 is supposed to be compatible with the GS3. For the present, the solution is to stay with the WEP encryption. I intend to contact Netgear to see why I can't connect with their WPA or WPA2 options.

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!

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.

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

[Q] wifi and mobile network keeps disconnecting

Hi
i'm having some issues with the radio on my Nexus 5, it startet after i upgraded to 5.0.
I did this by first deleting all user data (i use stock fw, no root), then by flashing the factory images with fastboot.
What happens is that wifi keeps disconnecting very often, like every 2-3mins.
if i turn wifi off, the same dropout happens with the mobile network..
I thought this was just a bug that would be fixed in later releases, so i waited.
5.0.1 OTA popped in and did not fix my issue, so i did a factory reset (read that in 5.0.1 android resets more thoroughly).
Still it keeps disconnecting.
now when 5.1 was released i flashed that image (didn't edit the flash-all.bat file so there was another wipe), it still disconnects.
Can anyone help me diagnose this problem (i can try to do a logcat?) can i flash the old radio from 4.4 safely?
is there anyone having the same problem like me?
I don't have quite those symptoms, but I do have a Wi-Fi problem, ever since 5.0. My Wi-Fi connection drops at random times. You can see the drop outs on the battery page, and it just stops whatever network activity was happening at the time. If I'm using Chrome, I know it's going to fail when the progress bar goes to about a cm then stops. If I toggle Wi-Fi off and back on, or sometimes if I simply wait for about 30 seconds, it works again. With 5.0.1, I was using the 4.4.2 radio, which was a lot better, dropping the connection a lot less often. I hoped 5.1 would fix it, and it's better, but it still happens sometimes.

My problem has, though it is worse on some networks. It's worse on my own home router, for example, which is an Asus RT-N66U running Merlin firmware. It happens less often here at work, but it has happened here. Both of these networks are 2.4GHz only. It happens just infrequently enough that I can live with it, but it's annoying.

My N5 WiFi is always rock solid on baseband M8974A-2.0.50.2.22 on 5.02 Euphoria.
I connect regularly to an Asus RT-AC66U router @ 2.4GHz running Merlin . So I doubt its' router related.

Well, i only use wifi at home so i'm not sure.
I've been testing with wifi off at home to rule out wifi, but it keeps disconnecting on mobile network as well.
It doesnt happen during calls, just while browsing etc, using mobile data.
It also keep switching between LTE (with low signal -117dB) and Hsdpa (better signal, -117) so i tried locking it to use only GSM/CDMA, that didn't help either.
Now i tried setting up my old router to try anoteher wifi network, no luck..
Guess i must try kitkat radio, see if that works any better
edit: that didnt work either

I've been trying to isolate this problem forever, and I'm starting to think it is something about my router, after all. Could you possibly post the settings from your Wireless General and Professional tabs in the Merlin firmware?
I now have a perfectly stable phone. Nexus 5 with 5.1.1, rooted, TWRP recovery, Xposed alpha, otherwise stock. I found the source of my Wi-Fi disconnect problems: it was my Belkin WeMo switches! I unplugged them, and I haven't had a disconnect in over a week. I haven't experienced a single other problem with this setup. (knock wood)

Did you manage to resolve your wifi problem?
I bought the Moto G (2015) 2GB RAM / 16GB ROM for my wife and she's having problems with the home wifi. It often says there is a "connection error" and loops to try to connect again and then fails. Her work wifi seems to function ok.
Having read about similar problems with older moto gs, people recommended (1) turning on and off airplane mode. (2) changing channel number of router.
Both sometimes work and sometimes don't. But it's not really a permanent solution. I'm a bit reluctant to do a factory reset and reinstall everything if it won't resolve the problem. The device came with the latest firmware already installed (5.1.1) and I haven't rooted or unlocked bootloader so should be a pretty clean install.
Anyway, would like to hear that factory reseting could resolve this issue or not before trying.
Thanks for any advice!
Mine does it every now and then. I just unplug my router, wait a minute, plug it back in, and then it connects.

Yes. It works for me too. But what happens if you're on a public or work wifi where you can't reset the router? It doesn't really seem like a long term solution.
Is this a standard problem with this phone? Anyone else have a similar problem or preferably a solution?

Yeah resetting other than home router is not the answer. It's an Android issue as all my phones do it from time to time. I haven't been able to figure it out. The other "fix" if you can't reset the router is try going into the Wi-Fi settings, and forget the network/name, and then add it back as new. It takes longer, but it could work for you. That's how I get around it when connecting to work when it won't auto connect.
Hi, I had also faced the same problem with a open wifi network which is free for 15 mins ..
Other than that one ..i had every router connected to my phone..
I was thinking the problem is not in your phone.. It's in router which might be old ��
Because old routers will have 802 a or something which are in compatible to some phones..
Or the router is not allowing your phone to get connected.. As your phone is latest and it has advanced protocols inscribed in it..
Do one thing.. Shed some light on this now :
1) router model (if known to you)
2) phone models which got connected to that router and it's operating system version (like 5.1.1)
And there is also one more point.. I found our phone might find problems connecting to 5ghz band router ..while it works fine for smaller routers like 2.4ghz
We can decide when you dig some info about the questions I mentioned...
We will get answers
Just turn off wifi and then turn it on it will fix the problem

You would think it would be that simple, but it's not. It just sits there "Connecting", then nothing, then "Connecting". Keeps cycling like that.

My router is a netgear CG3100Dv3 (using WPA2-PSK [AES] encryption) and uses 2.4 GHz. I don't think it's the router's fault though because I've had many friends connect with a variety of phones and none of them have had the problem before. I currently have a Oneplus One (android 5.0.2) and have used a Nexus 4 and Samsung Galaxy S (1) on this router without problems. Maybe it's a problem with android 5.1.1 as I guess not many of my friends have it yet. I've written to motorola support but they still havent got back to me.

Strange. I've never had a problem before with wifi. Maybe I've been lucky until now. Yep - have tried forgetting and reconnecting to wifi signal. Again, a temporary solution that will quickly become irritating when there shouldn't really be a problem for such a simple operation.

It's a temporary solution but a pain in the arse if you have to reset the router every few hours. And as I said before, what happens when you can't connect to a router which you can't reset? (i.e. public, work)
Change the router's channel, then refresh the wifi in the phone.

Firstly i agree that our Moto G has some kind of issue with some routers.. but there will be solutions for them from the ROUTERS POINT OF SIDE to make it work
i have read about your router .. Things i suggest (if you have already done them then let me know )
1) your router has option to change MODE to get speeds more than 150mbps.. try changing that 802.11 MODE , restart your Phone and Router and also keep CHANNEL to AUTO , try changing the security WPA to others also..
2) your Wifi of your phone will have a MAC address , copy that and paste in your Router to allow this device..
i am still finding info on your problem..
the reason why i think your Router can solve the problem is : i had once read about 802.11 b/g/n/ac types.. i am getting a doubt that they are the ones causing the problem.. if you are aware of it
have a look at this bro once : http://www.smartmobilephonesolutions.com/content/cant-connect-to-wifi-on-android-smartphone
in this he said that Wifi fix apps can solve the easy problems..:highfive: , hope you find solution

Hmm. That doesn't sound promising. Will they sort it out with the next firmware update? Are motorola even aware there is this problem?

1) your router has option to change MODE to get speeds more than 150mbps.. try changing that 802.11 MODE , restart your Phone and Router and also keep CHANNEL to AUTO , try changing the security WPA to others also..
2) your Wifi of your phone will have a MAC address , copy that and paste in your Router to allow this device.

Ok. Will change channel to auto mode. It was already on "up to 300 Mbps". Will also put MAC addresss in the router.
However this still relies on having access to the router. What happens when you don't have access. If this is going to happen on many routers then I prefer to return the phone and buy one which never has this problem.

I'll give a wifi fix app a go to. But they just seem to automatically delete known wifi SSIDs and passwords.
Another option would be to root and install new ROM and radio, but would prefer not to.
It seems like a lot of Nexus 5 users on 5.1.1 are having wifi problems too:

Anyway, thanks for you advice!
Just a quick update if there is anyone else reading this thread with a similar problem.
I changed the channel mode to auto and that has seemed to fix the problem. The moto g seems to connect without problems now. I didn't enter the MAC address nor used a "wifi fix" app so far.
Fingers crossed...
I have the same problem. Wifi just stops working and had a ! Symbol beside the wifi icon. I have probably had a 100 phones and devices connected to this router without a problem. I have changed a bunch of settings the router and it didn't help.
Disabling wifi off then on works, but that is no solution. I will try anther Rom or kernel. I am on resurrection 5.1.1

My problem was slightly different in that the phone wouldn't even connect to the wifi signal. It would cycle continuously between "connecting" and "authentication error".
Does it work with other routers?

Thanks for your help! I'm still a little wary that the phone will have problems in the future on other routers, but it's a good enough fix for now. Hopefully a later firmware update will sort it out.
Unfortunately, my wife took the moto g on a business trip last week and could not connect to any wifi signals (her colleagues did not have a problem).
Not sure what to do now. I'm in contact with motorola support but they don't have any suggestions yet (apart from blaming the router - which has never had a problem with any other devices!)

Well I just emailed Amazon and they're sending a replacement. Hopefully this will solve the problem
