Wifi Issue: sell GT7 or wait for ICS

Dear seasoned Xda members,
I love my GT7+ and have enjoyed the versatility of the Android Os (my first device). As I carry the device around and (attempt to) use it at work the size is perfect. However, I have terrible issues with the WIFI. At home there is no issue - but I work in a hospital, and the device is only good for me if it can get WIFI.
Well... in the hospital it will connect to both the "guest" wifi and the "secure" wifi (for which my device has been setup), but in both cases the connection just "dies" after about 2 minutes. The only way to get on again it by re-booting the device.
I had hoped that all of the firmware updates would address the issue - and I have read that some routers are troublesome for the GT7+. Unfortunately I will have little control over what routers are being used.
The device is no use to me if I can't use it at work - and Im wondering if I should sell it or if ICS will resolve the Wifi issue.... I would appreciate any guidance even if its speculation.
[btw the device is entirely stock, not rooted, and using ADW instead of TW]
Cheers!

Here's samsung's ics update list.http://androidandme.com/2012/02/devices/official-samsung-android-4-0-update-list/. You'll probebly have to wait until Q2 or Q3 for ICS, unless someone ports CM9.

I guess it was my fault to get the WIFI only version thinking it would be easy to switch between networks. Seems like a bug that they should have wrinkled out before shipping a "Wifi-only" device.
In any case, if anyone is looking for another device to play with - shoot me an email (aliota [at] gmail.com)

I had the same issue prior. I bought this Tab twice and with both devices the same thing happened at work aswell. At home it was working perfect. At work any wireless connected but dropped in like 2 minutes. Very Frustrating. I was actually thinking of picking it up again assuming the issue had been fixed..

Have you tied to do a factory reset on the device and then reconfigure the wifi connections? I bounce between many wireless networks during my day and the connection is stable.
I did have a few reboots until I set the wifi to turn off with the screen and never to turn off when charging, now the device is rock solid.
I believe that once ICS is dropped there will be some custom firmwares (ROMS) available for the device. Every new device I see posts like this where there is one feature or another that is flaky, once the developers start working their wonders on it the device becomes wonderful. The biggest hold up right now for development is the WiFi driver. Based on history of other devices, eventually that will be overcome as well.

Interesting... I've tried this in the past without any luck, but will try again. I really want to keep the device because it is quite powerful and the 7" size makes it much more portable than a 10"+ tablet.
Thanks for the feedback.

I have noticed some wifi issues with mine also but they dont seem to big of a deal for what I use mine for. I would really recommend keeping it as it is duel-core, lightweight, can even fit in some pockets.
But rather you keep it or not I suppose depends what you use your tablet for mostly I suppose.

WiFi is connected even when 20KM away from hotspot

As title says, I went to the theatre today and realized I still had 5 bars of WiFi when I was 20KM away from home, was this a one time glitch or is it a known problem?

sounds familiar....
hey there,
I'm down here in New Zealand with a both versions of device, X & XL
my XL has the problem you speak about.
When i leave my house, it takes for ever to disconnect, pain of course because the 3G or 4G wont flip on while it thinks it is still on wifi.
When i return to my home/SSID the device takes for ever to reconnect, if it even does. i go to the wifi settings, and the connection initiation is just cycling, end attempts to connect, over and over.
I've thought i had fix it once before, by installing a new RUU. I was on RUU 1.77.708.3 Asia, could only find 1.77.708.2.
this seemed to fix disconnection on departure problem, but the cycling and hunting continued when i returned.
I have since found that this must be linked to the bluetooth. I say this because while the wifi is hunting/cycling i flip off the bluetooth and the wifi reconnects within seconds. I tested this more and with bluetooth disabled i have no wifi problems at all, but with bluetooth on, its gives my problems.
The second issue is the bluetooth its self. unlike my flawless desireHD, i can only stream music to my car head-deck, when i get a phone call, the music cuts out like it should, but the phone audio doesn't happen, been like that from the get go. wifi was a problem all the time because this dodgy bluetooth was on all the time so i could listen to music in the car and hopefully one day take calls in the car also.
well i have good news for me, today i flashed CleanROM.3.Standard .
http://forum.xda-developers.com/showthread.php?t=1655011
Today for the first time I can take calls over bluetooth in the car. this is good news because i was certain this was a hardware issue, even it it is, i am confident it can be resolved in the software now.
I'll do a few drive-by's my house tonight to test this wifi, see if that got resolved also. I'll let you know the result later.
I tell you all this in-case our issues are the same, it might save you some time... maybe.
good luck with, and check that bluetooth theory because i'm dying to know if its a common problem.
Cheers

Thank you for that very detailed post.
I also have bluetooth running (connected) to my car and it works flawlessly but it may be a cause for the WiFI staying connected as well. I will turn it off and see how it goes as the week progresses and keep this updated as well.
I would also like to flash clean rom but I am using the Rogers variant so I am worried it might not be compatible.

This has been a known problem since the HOX has been released.

First reaction: It's not a glitch, that's just really good WiFi...
Sent from my HTC One X using xda premium

I did those drive-by's......
Me again...
I did those drive-by's of my house, unfortunately there is no joy for me, still the WiFi behaves the same as before.
Its funny, down here we have assumed that the X is the same as the XL apart from the cpu. But in reality they are two completely different machines.

So I turned off Bluetooth and the problem does not occur anymore, WiFi disconnects as needed but it is obviously not a permanent fix. Another problem is the WiFi being on and off with 5 bars swapping between 4G and WiFi...

CleanROM again......
OK, I was doing some more reading and have since found that the developer of CleanROM has released a GSM patch so the hotspot on his ROMs now work.
You might remember i said earlier in this thread that CleanROM.3 worked best for me but the hotspot didn't work so i couldn't use it.
Now i have CleanROM installed again, Hotspot works, bluetooth both Audio & Phone work, and the WiFi at this stage seems to be doing what it should without having to manually toggle the bluetooth on and off. No apparent bugs to report at this stage.
Software Info on phone says this version is built around 1.29.728.12. I don't know if that means all ICS version of that number are good or not, but again its a place to start. Its looking like some versions have the issue and some don't, this re-assures me that it can be resolved within the software. I don't mind testing this stuff, as long as the developers don't mind developing it, and its a good learning curve.... its all good.
Check this CleanROM work out, it could be your answer.

I'll check back in in a day or so and update you on my WiFi situation.
Cheers!

Thanks again for all your research and assistance.
I have the Rogers variant, should be no problem flashing it to CleanROM correct? Also, for each new CleanROM update, I would have to wipe and flash again? Seems troublesome.
Can you advise on the process required to flash the ROM? I am new to Android and the steps in the thread is not as comprehensive.
Many thanks.

hi there, show you how to load roms, thats a big job for me....
...I'm new to this myself, but i know a tutorial that will save me a ton of typing.
you need to do 2 things first, before flashing roms.
1,Unlock your bootloader
2,Install clockworkmod
have a look at this ,
http://forum.xda-developers.com/showthread.php?t=1647272
Study this thread, very helpfull. He explains how to install clockworkmod on your device, once you have that done you are 80% there, and you only have to do this process once, once done, flashing roms will always be the last 20%, you never do this again.
Infact flashing roms and backing up your own rom is a very simply task. the commands are on a list, just choose them as you go. To backup, wipe, and flash a new rom takes me less than 10 minutes.
Go to you tube and look at this, this shows you how Clockworkmod works.

dont be freaked out, take it step by step, you'll be fine.
I also started this thread, regarding working roms for this wifi issue
http://forum.xda-developers.com/showthread.php?p=27585586#post27585586
no one has replyed yet, but it might yeild helpfull info later on perhaps

Thanks, I will do this shortly. Will unlocking the bootloader or doing any of the aforementioned steps give me the tampered signature?

Yes
yes, your phone will be marked.
Boot loader will be marked "Unlocked" , even if you relock it, its just gonna say "relocked" . nothing you can do about that.
The boot loader will also say "tampered" if you update the rom, but that msg dissappears completely if you update the phone via an RUU.exe

Can this hurt me with regards to warranty requests? I know I can remove the tampered status by flashing a stock ROM but I am concerned re: bootloader.

[Q] WiFi errors on the One S?

Ok, this is a strange one.
My wife got an Telus HTC One S (running stock ROM, I think it's ICS 4.0.3, might be 4.0.4) yesterday, and we've been having no end of troubles stemming from the WiFi.
First, we tried to install Swype over WiFi, and the download bar kept getting stuck at around 10%. Switching to the 3G network allowed us to install it. We figured it might be a Swype issue.
Then we started grabbing some apps from the App store over WiFi, and everything kept throwing the error "Package File is Invalid". We tried over 3G, and it worked fine.
Remembering some troubleshooting I had to do with my Galaxy S and its wonky WiFi, I set up the HTC to use a static IP. This worked, but only temporarily. After a few apps were downloaded, it started throwing the same "Invalid" error.
The general advice around the web seems to be clearing the Play store cache/data, and uninstalling its updates. We have tried that multiple times, with no luck. Besides which, the store works over 3G, just not WiFi, so I doubt it's the store itself.
We have two other Android devices in the house, running Gingerbread 2.3.3 and Honeycomb 3.2. Both of them can download fine over the same WiFi connection.
Because of this, I'm pretty sure it isn't the Play Store (since it works on 3G), nor the WiFi itself (since it works with other phones). My best guess is either the HTC One S's WiFi hardware is faulty, or it has a software/firmware bug.
Any ideas?
EDIT: At some point during this process, we also made sure to update to the latest firmware (1.84, I believe), just to rule that out. The firmware also kept saying it was corrupted if I downloaded it over WiFi. I had to download it over 3G to install the update.

you could try a custom rom, that might fix your issue, but void your warranty

Yeah, with a one-day-old phone, that's not going to happen yet. If it's hardware, we'll be getting it exchanged this weekend.

oh well yeah. if it's still within the exchange period then do that

Heh, that's the plan. I've been searching around trying to figure out if this was maybe a known problem for this phone, though, or a software issue that people knew how to fix. Doesn't look like it.
Thanks, though.

it could be a bad wifi chip or a fault in the antenna. probably just a hardware issue. defective electronics, the bane of the modern era

So we exchanged the phone, and have the same error on the new one. We took the second phone back and tried it on the store's WiFi, and it works there. So it looks like it's an issue with our WiFi network. But that's insane, because we already have two Android devices on the same network, and those work fine.
Are there any known incompatibilities with ICS and WiFi networks? I'm pulling my hair out here.

Same problem here,galaxy s2,after playing around with some custom roms,i went back to stock generic ics and now I have this ptoblem,i realised that on mobile data works perfect, my wifi is from virgin media,but 7 months while it was not rooted it did not have this problem at all. I have to mention that it doesn't happen to all apps from the matket.also once I got "nit enough memory" error which is hilarious. I don't know what is,but I will try to download the apps while I am out connected on other wifi ntw

if it's occured on multiple phones, i reinstate my opinion that you should attempt to root and flash a custom rom

For example I can't install blood brothers (not that I need it,just because I get points on money factory),but can install angry burds and a b rio which are bigget than the tirst one

Yeah, I don't really want to do that to my wife's phone when it's this new.
Luckily we found a workaround, by daisy-chaining our old router into the current one, and connecting the WiFi through the second one. Not ideal, but it works.

Unexpected problems after updating to MM through Smart Switch

Dear Forum,
My wife acquired the S6 last week and I helped her through the initial stuff of creating backup from her previous S3.
All went fine, all was where it should have been, nothing missing, great stuff.
The "Software Upgrade" utility inmediately tells you that there's an upgrade available to MM and I thought to myself "Well, that phone is from November 2015, the upgrade couldn't harm, in fact, it usually improves things", right ?
My wife asked if there was going to be an issue with the upgrade and if it would be possible to downgrade again....
So, I went to Kies3, which directed me to Smart Switch and I began the upgrade. After it was done I did a factory reset and the phone booted, all ok...so far...
I gave the phone to my wife (an avid Instagrammer) and she told me : this is not working, what have you done to my phone ? The nightmare begins for me...
1. Apparently the wifi signal was quite poor (even if sitting in front of the router). It takes some time to connect, which means that pages like Instagram, tumblr, facebook, even searches in Chrome take an eternity to load ! It didn't happen on version 5.1 apparently on her S6 (which I doubt) , and on her S3 it worked flawlessly. I have to say though that I experience the same issue on my current Z9 Max. I believe that the router (Glass Fiber connection) is quite old and not up to new standards, that's why it hangs with new phones. I only have wifi issues at home, any other router I connect to (Bars, brother home, mother home, at work) work perfectly fine. I will change the router as soon as I can, but I firmly believe it has to do with new hardware the router is not used to.
2. Mobile Data
They did not work at all... The look on my wife's face said it all "What the Eff have you done to my fresh new phone" ??? I'm asking this to myself also now...why did I upgrade this thing ? In the end I managed to get mobile data, simply by trying 3G, 2G, individual options and finally 4G worked again. But yeah, what do you do at home with a smartphone if you don't have an internet connection ?
Why did Samsung push-out this upgrade, why are they forcing messages onto the user that an upgrade is needed ? I mean, I've been using Android for quite some time and I've flashed many many Roms, installed software upgrades, I never ever faced any issue on my HTC or Nubia, all worked fine after an upgrade, at least mobile data were working always. Samsung is supposed to deliver top notch phones with top notch upgrades...how can they possibly offer/push something that might cause more trouble than joy ?
I assume a FW upgrade is needed as well, why don't they warn ?
Now the question.... if 5.1 worked fine, is there any possibility to downgrade the S6 to a previous Android version ? Would it be possible with Odin ?
I got an angry wife sitting at home , which is convinced that I only wanted to play around and didn't want to help her.
Have you guys experienced problems after upgrade to MM on the S6 ?
Cheers,
Ken

Question Home Wi-Fi, sluggish apps

Hi. I have not visited since some time this great place, but for some time i'm encounter some issues with my S21+, Exynos version with 8Gb/128Gb.
More exactly, i have some long waiting-times when i'm opening some apps during my home connection via Wi-Fi, on both versions: 2.4Ghz and 5Ghz. For instance, Samsung Weather almost is not updating when i'm requesting this or if i'm opening the app. On other apps, local one, similar with ebay, i cannot access my account, it just shows me that is loading, but nothing happens. Strange is that if i'm connected via mobile-data, i don't have this issues. This leads me to believe that is something wrong with my Wi-Fi connections, only that i don't know what's the problem. I'm having a lot of other devices connected to wi-fi and no issue. I'm owing this phone since more than one year and this issues i'm encounter only in the last 1,5months, i would say. I remember that also in the past i've encounter same issues with the former galaxy phones i have owned: Galaxy S9 and Galaxy S20+. Last week i've also performed two times Factory Reset from the Recovery, but seems that this annoying issues continue. This is the reason i've finally landed here as seems for me the last place to receive some advices. During first reset i've restored some backups i've did before, but noticed the same problems. Second time i did not restored anything and no improvements. I really don't understand what should be wrong with my wi-fi network as long as is worked for one year and afterwards suddenly it creates me headaches. Phone is updated to the latest available OTA software which is Android 12, ONE UI 4.1, baseband ver: ...CVH7
Any advices will be kindly appreciated. Somehow, Samsung is trying to convince me that i need to upgrade? Which seems sad for me after so many years spent with them, more than ten years when i have owned i think all their galaxy models.

I've found the answer to my trouble. Seems i was not alone. The solve is to disable IPv6 from your router and this type of issues are solved later. Topic closed.
