hi guys good day! .it is running on jellybean 4.1.1 and equiped with rk3066 chipset.the problem is when im far from our wifi router like 5 meters away my wifi signal drops to 1 bar i have already updated our router to the latest firmware but unfortunately the problem still exist. i think my tablet's wifi driver is the problem. .is there anyone could help me to fix this problem? thank you im willing to upload my wifi driver for you to modify it i know that there are lots of devs here in xda that could help me.

AFAIK not all drivers can be modified because they are not all open source , i guess your tablet is chinease and very cheap , maybe it is just a hardware issue , do you have the same problem when you try to connect to another router (in a public place , your friend's....)? , since when did you start having this problem i mean did you already manage to connect to that same router with your tablet while being farther than 5 meters? and are your other devices connecting without problems to your router ?

AFAIK the only way to be sure if it is a software (android?) or a hardware issue is to reset your device after backing up everything (nandroid backup if rooted or something else), if the problem is still present after reseting your device i am 90% sure it is a hardware issue , in this last case you can go to your manufacturer support center or send them your device to repare it , if your device is still under wanrenty it might be free of charge , if it is a software issue , resseting your device should solve the issue but you will lose your data (if you backed up your apps on your sd or on the cloud it will be easy to get them back) , to reset your device if you are rooted (after backing up everything) go to your custom recovery (twrp , clockworkmod...) and then go to factory reset (or something like that :silly: ) and select the only "yes" option that you will see in the screen , if you are not rooted (stock rom) you normally will find an option for resetting on system settings/personal/backup and reset (i am on cm9 it might be different for you but just look for reset option in settings you might be asked for your gmail account to be sure you are the owner of the device) , normally resetting is a natural process but i am not responsible for any damage that might happen to your device (be careful with cwm and BACK UP everything)

[Q] Wifi hotspot and usb tethering problem on GB

Hi, I finally decided to post my question after many hours searching trough google and xda.
Two weeks ago like many of you I uptdated my x10 to pre-rooted 2.3.3 stock Rom. At this moment I successfully tested wifi hotspot and usb tethering built in fonctions.
But Recently I tried to use it again but any time I checked the option, Android activate it for a second, an then says me "error" under the option name. Usb tehter can't be reactived at all and wifi hotspot can be checked but always uncheck himslef with the error subtitle.
Anyone facing this issue or know where it can come from ? And maybe the fix of course ^^.
Hope I made my self clear because actually I'm french.

I use Baracle to solve the issue with wifi tethering
https://market.android.com/details?id=net.szym.barnacle&feature=search_result
Yeah this is the solution I used to adopte when was on 2.1. And it was the best until the update.
But as far as what I tested when built-in tether worked it's clearly better. Not just an Ah-hod network but a real hotspot. Basically it's easier for other devices to connect and remember the password without configuring everything especially on windows.
And the usb option was even better, nothing to configure, no password, battery charging during tethering.
Anyway thank for the advice, until I get the solution I'll probably continue to use this app.
When you say "solve the problem with wifi tethering", do you mean you have the same one ?

Please, no one else, am I the only one facing the issue ? Even on an other device maybe ?
Finally I used SEUS to repare and root it like azazu said. Everything is back. Didn't find any other solution

I have the same problem and it never has been working from the start ! but USB tethering has no problem. The only way to fix it is to re-flash ?
Well I guess this is the best until someone more expert than us find a solution. I made a reparation with SEUS (sony ericsson update service) and then restore all back with Titanium Backup. Remember to save your contacts and sms before (cause Titanium doesn't). It only took one hours to get it all back just like before (root, bravia, Xloud, fps uncap...)
Hotspot error UNSOLVED 2012-02-01
Here's what I've done so far. I've suffered from this issue on two different Samsung Galaxy TAB's 7" (1 generation), two different Samsung Galaxy S2, two different HTC Desire HD, one ZTE Blade.
This issue is NOT caused by:
*Manufacture of phone
*Internet Service Provider (ISP)
*Operator
*Bluetooth ON/OFF
*root ON/OFF
*Stock Kernel
*Mod Kernel
*Stock Rom
*Mod Rom
*Stock Modem
*Mod Modem
*Android version: 2.3+ has this issue. (I've experienced a different issue on 4.0+; the Hotspot is up running although no device can connect to it.)
The only solution I've found is:
(From Clockwork Recovery):
Wipe Data(system reset)
Wipe Cache
Wipe Dalvik
Format Cache
Format Data
Format System
-Install a Rom (try a different one from what you are using right now).
Reboot
RESULT:
Hotspot working fine....for a while..
When it stops working; you'll have to do the steps above again. Install a different ROM, now you probably can return to your previously ROM which had this issue first. It will probably work. If it doesn't, switch ROM till you find one that works. Sometimes, total randomly; you will be able to use ROMS which this issue has been present earlier.
Yet, this is NOT a permanent solution. You will, no exceptions, experience this issue, on whatever ROM, modem, kernel, stock, not stock, phone, whatever, whatever you choose.
Here's one scenario which I couldn't figure out:
Galaxy TAB 7" 1st generation.
Android 2.3.4
*HOTSPOT ERROR*
WIPE/FORMAT
RE-Flashed Same Rom
*HOTSPOT WORKING*
1 hour later
*HOTSPOT ERROR*
WIPE/FORMAT
RE-Flashed Same Rom
*HOTSPOT WORKING*
5-10 minutes later
*HOTSPOT ERROR*
WIPE/FORMAT
RE-Flashed Same Rom
*HOTSPOT ERROR*
?????
I've also noticed that USB tethering is affected by this issue aswell.
If you have it working, congratulations! Use it while it lasts, nothing stays forever.

[Q] Root will me wifi, Now: Stuck installing ClockworkMod Recovery to install new ROM

Hello everyone,
first of all, I am new on this Android world, so, any basic question I post, I ask for understanding in advance.
Trying to root my Viewpad 7 (Froyo 2.2), I come across to GingerBreak, I run it and it sucessfully root but it killed my Wifi (that's all connectivity I used, I have no mobile data plan)
as I wanted also to try new rooms, and flash a new one seems to be a only solution for the wifi problem (I have try factory settings without success). I come across Rom manager,
I download and install ROM_Manager_Premium_v4.3.2.3.apk from SD
and download CleanViewpad7_signed_v1.0.zip to my sd card
If I try to flash ClockworkMod Recovery from ROM manager, i get:
"Error while downloading from the server. Please make sure you have a stable internet conection ..." but that's no possible as I have no WIFI in my viewPad7 after root!
If I try to Install ROM from SD card (from Rom manager), the device restore in "Recovery mode" of "Andoid system recovery <3e>"; and it brakes with message "E:signature verification failed".
I have donwload it from several servers (http://forum.xda-developers.com/showthread.php?t=1168562), and all give the same error mesaage
I try to search for manual mode to install clockwork (http://forum.xda-developers.com/showthread.php?t=755379) but I can not find a way to go.
"wipe data/factory reset" inicializate the device, but it doesn't help with the wifi. it keet saying scaning->disconected->scanning->disconected ... (and of course, my wifi conection is set to remember with the password memorized)
In the cofig menu, i can see:
baseband: PR3.7_128
Kernel Apps_2.6.32.9
Build 4027_3_16R
In the FTM mode:
SWver=3.16R
Model:FM6-0001
HWVer:106
what can I do?, I just have a 7inch no apps-no connection beautifull "thing"
More: I have try two other Rooms:
EUViewpadV1.4.zip
Viewpad7 Stock EU 2.2 +rooted+CWM.zip
nothing works, signature verification failed

Okay, you willl be fine - just need to flash & restore it first to factory/stock ROM first, then root it and go from there - here are the steps that I would suggest:
First, save anything important on your mSD card if you need to, perhaps to a USB drive and/or computer's hard drive.
Next, use this link http://forum.xda-developers.com/showthread.php?t=1260463 to download - for the stock ROMs from Viewsonic.
The newest one is for newer ITE hardware VPAD7 (and, I believe yours is NOT if you could get CleanViewpad v1.0 to boot up & activate the screen - and a number of users are having trouble with wifi ....) To override that signature verification error message that you get, look into CWM (I'm using v3.0.2.8) under Apply update from .zip file on SD card, and there's a "toggle signature verification" switch - change it and trying applying the zip file again to flash - it should work, as I recall. Before that, make sure you wipe system/cache/dalvik & reset data, etc. for a clean(er) new installation.
FM6-316Q-*.nb0 should work with earlier, non-ITE Vpad7 and so should FM6-3310-*.nb0, whereas the FM6-3350-*.nb0 should be for newer ITE devices with either HWver 107 and/or (some) HWver 106.
To flash it, you CANNOT use CWM but must download the SUTL3 (v1.7.9 worked for me) - read & following the onscreen warnings/directions and it should be finished in less than 10 minutes (have the Vpad7 fully charged first & do NOT need to have the mSD card installed)
When it's finished, reinstall the mSD card, take a deep breath & reboot/restart, and you should be up & running with the stock ROM in a few minutes - if so, check your wifi connectivity first before going any further. Start with 316Q ROM first and if it's good, you might want to move up to 3310 next (it's newer) & recheck wifi connectivity. STOP then, as yours is non-ITE and the 3350 will NOT work. You can then flash CWM and/or root it - with SOC or GB methods, etc. etc. which you're familiar with.
I had no problems with wifi connectivity and/or 3G data (prepaid GSM 3G coverage) running the Froyo Enhanced custom ROM (non-OC version since I have ITE hardware) OS 2.2 - However, I'm running stock ROM OS 2.2.2 rooted and wifi is perfect for me. (I'm written up a quck tip/guide also - in case you didn't come across it while searching for answers) http://forum.xda-developers.com/showthread.php?t=1264647
Lastly, TJ_Style's FM6 ROM w overclocked kernel should work for you as well, it's OS 2.2 but I patched the boot.img with my saved newer 2.2.2 ITE kernel and got it working too, and, no issues with wifi access at all.
In short, check & change your Signature Verification options under CWM and try again, and, if not - restore by reflashing with SUTL3 a factory *.nb0 file, then - proceed from there.
Good luck, have a bit of patience - it's both fun & exciting, challenging & disappointment often followed by the joy of luck & success. Let us know how it go & write down any error message(s) so we can help figure it out together - plenty of "newbies" been around but still stranded at times.
Regards -
Thanks, SUTL3_v1.7.9 and FM6-3310-0-5029-A02.nb0 works like a charm, easy and bring back my ViewPad7 to work,
for anybodies info, that change my ViewPad to:
Android version : 2.2.2 (from 2.2)
Baseband version PR3.7_128 (same)
Kernel Version Apps_2.6.32.9 (same)
Build Number 5029_3_310 (from 4027_3_16R)
I got encouraged, and I try FM6-3350-0-1008-A01.nb0, that gives me:
Android version : 2.2.2 (from 2.2)
Baseband version PR3.7_128 (same)
Kernel Version Apps_2.6.32.9 (same)
Build Number 1008_3_350 (from 4027_3_16R)
Swype included !! (seems a little odd and disordered the configuration process, so skip it)
what means ITI / non-ITI ?
languajes: both nb0 are English/Spanish/French only
now I will start with rooting and so, I will let you know
once more, many thanks.
Wonderful, we are all glad to know that you had success. Is your wifi working once again with either stock unrooted ROM?
Once rooted & CWM reinstalled, do a backup first to save those *.img files, etc. so that you can easily restore/go back later on if necessary.
As I said, check out Enhanced Froyo and TJ_Style's FM6 custom ROMs, both of them should work nicely for you - including wifi (I believe, as least on mine - both solid signals in both G and N routers, WEP & WPA-2 modes. (Also, try open or unsecured mode)
Happy flashing ....
YES !!, wifi is working back to normal. At least sometimes (I have need to re-flash few time already, it has stoped working few times more, and not becouse of rooting, just installing apps from market)
I have also encoutered the next problem : http://www.youtube.com/watch?v=6XuccAxXY_8
and that shouldn't be normal behaviour?, isn't it ?
try with diferent room or return to viewsonic ?
by the way, what ITE means ?
thanks once more

ITE refers to Panjit Touchscreen (Multi-Touch Resistive) used on newer Vpad7 built & shippped vs. older hardwares used on earlier models.
On that subject, I've looked at a # of youtube video reviews & posting about the device's orientation/rotation issues, and it seemed to me that it prefer to be in a landscape mode. But, there are times where we wanted to have a choice, turn it 90 degree for a vertical or straight up - not so sure it's 99% hardware problem - rather, problem caused by a mix of Android codes & Apps used. Some were defective but that's a production & quality control issue, so, anyway.
I'm not sure after seeing at your YT video what the problem is, please describe & I will have another look with my thoughts on it.
Does it happen with the stock/factory ROM or only with the ROM being runned now - I would flash a different ROM to compare the results.
Sending it back to Viewsonic is an option but you will be without its use for 2 to 4 weeks (usual timeframe, could be longer) & deal with packing, insuring, shipping & waiting - but, if it's "bad" - get authorization & exchange it or repaired.
Regards !
Bad news, as later day, wifi come alive, it went down sometimes, and as I was trying application I flash the three diferent factory rooms few times. What I didn't notice is that the wifo was disconecting more and more often: now it does connect at all.
As said, I have try the three diferent ROM in viewsonic, and also an app called FixMyWifi, nothing helps, wife is all the time "Connecting..."->"Disconected"->"Searching"->and so on
about the strange behiviour of the screen, the matter is that as soon as using two fingers, the right one, can not be in lower position than the left one. So forgot about plenty of games, drawinf with two fingers, dificulto for rotating maps (when the rotation of finger goes beyond 90 degres)
And one of the reasons I bought it is my little boy, explain that to a children of four years..., in deed he found it as "that does work well, the tank does not follow my fingers"
so, as a multitouch is basically pointless if you have to care your right finger does not go bellow your left one ...
Anything to do with the Wifi ?
rooting may help in some way?, and some terminal comands?
I am willing to try, I am just in the point before return it as faulty device.
Many thanks for all the help given.

Thanks for clarifying and I looked at the YT video again - perhaps you would be better off getting Viewsonic for authorization to return for repair or exchange it. On my device, the screen is responsive 98% of the time but I do realize that sometimes, when we're playing Angry Birds, that it too doesn't always readily respond to commands or launch the bird shots .... Not a big deal for games, it will usually get going again - worst case, use the Go Back key & restart the level - I figure that it could be a combination of the Froyo or Android codes written for the OS and/or along with the Angry Birds gaming itself.
Afterall, my "regular" & 2 years old smartphone, HTC Eris running a nearly identical CPU & configuration is running custom rooted GingerBread ROM - and, is must better & responsive in overclocked mode. The Vpad7 will not, I feel, be running Honeycomb but let's hope that some of the veteran xda developers will soon release a working GingerBread ROM - perhaps it will fix many of the issues across the field, so to speak. (or, if Viewsonic will release it as official update .... wishful thinking, huh - but !)
On the wifi issues, have you tried doing the SuperOneClick and/or GingerBreak apk to root, and then flash TJ_Style's custom FM6 ROM - http://forum.xda-developers.com/showthread.php?t=1264647 - this OC version with WiFi fix might work for you without any mods (patching or zip flashing the 2.2.2 boot.img)
On wifi configuration itself, is this happening with different routers - "older" G mode or newer N (faster) routers, unsecured or open network or secured (WEP, WPA or WPA2, etc.) - any issues on the host computer/router's firewall blocking ? Can you log in at a public hotspot or cafe like Starbuck ?
Go into Settings > Wireless & network settings > Wi-Fi settings > and, then, tap the Home key (the bottom of 4 keys on the device - held in landscape mode) and you should see "Scan" & "Advanced" - does it pickup a decent signal ? Click "Advanced" & look at your "Wi-Fi sleep policy" - mine is checked for "When screen turn off" - tried "Never" or "Never when plugged in" - any difference ? If you get this far, you might want to try to set up & Use "static IP" instead of using dynamic ip addressing that these devices usually count on .... it's a bit of work, but might help to "zoom" into your own router only.
I use "Wifi Analyzer" v2.5.13 from Kevin Yuan (Google Market) to help scan the spectrum for signals and possible interference, which sometimes do happen - and moved 1 of our 2 cable broadband router to a different channel so that all of our wireless (up to 15 of them, yes) devices around the house can easily connect to the hotspots. (Reading posts @ other forum sites & ran my inSSIDer v2.0 from Dell laptop for baseline, it scanned 17 active APN's with varying signal strengths, our Sony W995 picked up only 6 signals with 3 good ones, the HTC Eris picked up 6 signals also with 3 good ones, and the Vpad7 only 3 signals, 2 of them from our own indoor G & N routers plus 1 from neighbors that's marginal. It's safe to assume that our device's internal radio receiver or Baseband isn't very good with reception to begin with - you might need to flash a different "build" like mine to give it a try - and try switching your wifi channel.)
Just some of my thoughts on the wifi problem as I do run into signal problems myself every so often installing a new device or configure a guest's new gadget at home. If all else failed and along with the touchscreen problem, then I would say get it fixed via repair or exchange from Viewsonic, and then .... (a few weeks later, upon its return to you - happy rooting & flashing, etc.)

about the wifi issue, I have try all the steps you mention before, nothing helps with my router (deliver by the telephone company). The only thing that works, sometimes, s turning off the router for several seconds, then it connect again. As absurd it sounds, it looks like the viewpad doesn't disconnect from the router even as turned off, so the router doesn't allow to negociated again a conection (and it keeps it in connected device while the viewpad is reseting or turned off)
I have try connecting a Linksys Wi-fi and connecting trought it : WORKS GREAT.
Trying in different locations, some of them same problem as the router, others works perfectly.
Solved for home with second wifi-point, I see myself one day asking Starbuchs guy to reset their router...

SGS2 loses network / wifi and problems with data

I have huge problems with my SGS2 , after update ( I think so ) to official android 4.0.3 (I9100XXLPS) it constantly loses 3G network when not using SGS2 or browsing internet on it.
But it never loses network when talking with with someone , it keeps voice and data connection correctly.
It also loses both wifi / 3G network at same time when I am connected to net via wifi.
But thats not all...
Also happens pretty often that SGS2 sends some data but never receives response from network and for example net communicators like ICQ loses connection when it occur.
Tonight it lost 3G network which I picked manually earlier and displayed error that selected network is unavailable , SGS2 started looking for all networks and it found none displaying that there was error when searching for networks ( that error honestly happens very often even when SGS2 is connected to some network )
I tried of course wipe , even flashing firmware via odin but its always the same.
For now I flashed modem KI4 to see if it changes anything , but looking forward for any tips.
Try flashing a different kernel to help with your wifi problems like Siyah / Neak / Redpill and different modems to see if that helps with your signal / data
unfortunately ...
changing modem / kernel didn't helped ...
its still loosing network and don't wanna connect again until I reboot it.
Even exchanged sim card to new but no luck.
So should I give it to Samsung so they hopefully fix it ?
Sounds like a hardware issue... darn that sucks.

and I seriously have enough of doing wipes :/
Wanted some stable android device , not the one that needs wipes every week, earlier I had Galaxy Gio and were no such problems there.
I even started thinking about Iphone , but sad to loose all those applications that I bought at Android Market .
I used many roms and this rom is the best one check link http://forum.xda-developers.com/showthread.php?t=1436854

Thanks for posting link , tho after reading issues list in this ROM , I won't even try it.

Also on most of those roms ( Cyanogenmod, Miui based roms ) 3G video talk and FM Radio is not working which I am using often.
chmmm I flashed NELP3 modem and is stopped for now loosing 3G network and generally data connection works better too just ...
exactly every 2 hours it closes data connection and connects again, maybe there is somewhere some hidden setting which sets maximum session time ?
You should wipe phone flash original rom and test if it fails return under warranty .
jje
hehe thats what I was about to do , wipe totally all data, from internal sdcard memory too. ( just 1st making backup of all data )
Then flash using odin the newest official firmware for my country.
ehhh after full wipe and flash well , it doesn't seems to drop 3G network , but does drop data connection every few minutes
and it does it even with sim card from different operator
so seems only samsung service for me :/
edit :
nah it drops also 3G network totally.
you are sure guys its not software fault ?
couse I read A LOT of threads on this forum and others , that SGS2 and other Samsung phones have this issue and they saying samsung knows it and working on it ...
Software ICS yes possible .
Test by flashing stock GB rom .
jje
seems its working MUCH better on Android 2.3.5 .
But .... Why my friend who have SGS2 and ICS ( same as me ) also same mobile operator don't have any problems with network ?
Seems will give it to Samsung anyway , as I wanted stable ICS :/

You need a motherboard replacement.
If your phone is still covered by warranty, you can send it to a Motorola repair center to have it fixed (and wait 2 or 3 months).

Then there is no solution.
Mine is still under warranty, I sent it to Motorola two months ago, and they have NOT fixed it yet.
I will NEVER buy another Moto again.
I had this problem with wifi (mac 02:00...) and it came out to be a 100% software problem. I got it as a result of unsuccessful BL unlock, twrp, then root... Finally I decided to get back to locked BL and stock ROM. And "voila!" my wifi is back and is fully functional...
Very Well

Congrants :good:
That is a great new for all of us (if the cause is the same of course).
now the big question, how did you do it?. You could be a little more specific please.
1. what stock frimware you used?
I try whit this (XT1650-03_GRIFFIN_RETAIL_7.1.1_NPLS26.118-20-5-3_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip) this because the build number of my moto z in this moment is NPLS26.118-20-5-3 but i dont sure.
The Frimware i got it from this web https: //mirrors.lolinet.com/ firmware/moto/griffin/official/RETUS/
2. You previous version ROM ( 7.1.1. ) of android corresponse to the new version stock (7.1.1.) you used to flash or are diferents ??.
3. The Build Number Version was equals?
Thanks for your time!!
i got it fixed when i formatted my cell from recovery now wifi is working but bluetooth is not so definitely its not the hardware issue its only related to software
I have a similar problem with wifi (and hotspot) in my Moto Z. Wifi MAC is 02:00:00:00:00:00.
The battery is also drained really quick - it lasts only 1 day.
The problem occurred a few days ago without any good reason - I did not update nor install anything lately. I tried wiping cache - no success.
edit:
MAC has returned to normal, bluetooth is working.
Wifi still does not find any networks.
My battery mod does not charge the phone - I have no idea why

How did you got it back ? Explain something
I did not get it back - wifi still does not work, only MAC returned to normal.
I did not do anything special - just discharged and recharged the phone a few times.
Yesterday I reflashed the kernel (latest TurboZ), wiped cache and power drainage has returned to normal, but MAC is again 02:00:00:00:00:00. No idea why.

Question Pixel 6 wifi bug

I got pixel 6 2 months ago .. when I unboxed I couldn't connect to wifi cause it couldn't find any wifi network ... After February update the problem still remains even after March update... I can connect by putting my device in airplanemode then reboot the device and my device can connect to any wifi without any problem and I can switch airplamode off and still connected ... Who has this bug too van we find a fix for it .. and thanx..
I just got my Pixel 6 about a week ago and don't have this issue. The phone came with the Jan update and I updated to the March update (skipped Feb update because of its issues). Since this is likely a software issue, I'm thinking a factory reset (without restoring from backup) may help you?

Before the big hassle of resetting the phone, maybe try a smaller hassle first. When a network device has trouble looking up names it could be time to flush the router's DNS cache. For home routers this usually means a factory reset if the firmware doesn't have the option.
have you tried a network reset back to default values?
i cant remember where i saw it, but its a feature
Ive tried every method from network reset to factory reset to full flash firmware .... Nothing happened ... Same problem still there
Is this only happening with one access point? If yes, maybe the AP has a configuration which is not suitable for ur phone.
I personally never experienced any WiFi issues since I have the mobile.
Cheers
Tom
I was going to say much the same - find a friend/family AP to test with to compare.
I tried another 5 ap...still problem
