[Q] n00b question- rooting & OTA updates, 'unable to scan networks'

HI there, I have the dreaded 'unable to scan networks' wifi problem- it started after I set up a mobile AP (I didn't turn the AP service off after I'd finished with it- I wonder if that's what caused it?)...
Anyway, I've since learned via this board that I can fix my wifi by 2 methods: 1) performing a reset (would rather not) and 2) editing a line somewhere, root access is required.
I do have a third option- waiting until the 2.2 OTA update comes through, which I understand will require (and perform) a reset anyway.
However, I'm sick of waiting for 2.2.
What I'd like to know is: If I root my phone & fix my Wifi, will I still receive the OTA update?
Anybody?
TIA.

the 2.2 froyo is not OTA
it is OTK (over the kies)
just turn off your phone, then turn it back on, that should reset your WiFi stuck i/o
some times the GPS does that too, just turn off the phone, turn it back on and they work right away.
in contrast to the HTC Windows Mobile phones, the SGS is much much much better, i barely have to do any restart of the phone with Android
with Windows Mobile it was at least 10 reboot a day

Restart doesn't fix it... Tried removing battery, etc. etc.
The 'unable to scan networks' problem is a known issue- at least to this board, If not to samsung.

Im in the same boat as you mate with my Samsung galaxy s, i have tried turning it on and off with alternate battery in and out methods, my wi-fi just wont work now, it turns on, comes up saying "Unable to scan networks" and turns the wifi off.
I have read on many posts about the issue and the best fix appears to be here:
hxxp://forum.xda-developers.com/showthread.php?p=8062313
*Sorry its not linked, this is my first post so i assume it wont let me post links until im roughly around the 25th post mark.
The issue i find with using this method is that in order to browse the phone at a root level to get to that file, you need to pay for the App in the android market to do it.
I have rooted my phone already and already applied the lag fix (boy did that change things), but im more contemplating doing the upgrade to 2.2 than buying the app just to fix a wifi issue. Im hoping this gets fixed in 2.2, or at least a more easier solution / fix.
My question is, if i did buy the app to browse the phones file system and i fix the wifi, does it fix it permanently or just until it happens again and i will have to follow the same process again... ?

did you both turn off Bluetooth when using WiFi?
you can't use BT when using WiFi

I've never had to turn off bluetooth to use wifi before...
However: PROBLEM IS NOW FIXED!!
Here's how I did it:
First, bluetooth was off.
Tried to upload a video shot on the phone to youtube. Got message along the lines of 'will only upload video over wifi'
Next message pops up: 'waiting for wifi'
THEN message box saying' signal strength excellent' & asking for my wifi password!
I've been without wifi for 2 weeks, this is brilliant. Give it a go, try uploading a video to youtube.
I reckon it overwrites the bad line, but who knows. Maybe its a bluetooth thing. I don't care, it worked for me.
Spread the news!

how would I go about updating, when 2.2 is official, without kies or rooting? I've lost patience with kies!

This was mentioned on another topic already but here it is again:
Heimdall, Odin, Rom Manager Clockwork just to name a few, there are many other ways to go about this even without Kies

cool, cheers! I think I will try Odin!

Flashed back to stock and now wifi won't connect amongst other issues. :-\

Been having horrible troubles with my bionic since the update. Not that it was stellar before it, would drop data often, but it was better then now. After the update the phone randomly reboots while on calls and the tethering app fails often. I have to power cycle phone to get it to work again. Since I'm paying for the tethering feature I'd like it to work.
Well I had only rooted my device and flash Bigndad's theme on my device. That was it. I had flashed the restore to the theme that was in the thread. But I think it was missing stuff cause i failed the update calling out various things that the theme re-skinned. Nothing I had edited or touched on my own. So I replaced the "bad" files and updated. It passed and updated, however, my phone sucked badly. Tethering was really hit or miss. And random rebooting while on calls SUCK.
So I did a factory reset last night at work. Still tether wouldn't function right, even with nothing else installed. So I used r3l3ased and forever root to restore me back to stock OS the phone came with and rerooted. Now my system should be perfect and working with no issues. I did the update fine this time. No hiccups. However...tether is still broken and hit or miss at best. Seems to stop working randomly and I still have to reboot phone to get it to work and now my wifi on the device will not connect at all to my home network and it worked fine before the flash. Just will refuse to connect. Sees network but can't authenticate.
What is left for me to do? Honestly? Is there a red lite or fastboot flashable file of the current updated OS that works that i can just flash over mine and hope it fixes the issues? Getting frustrated. I can kinda deal with no wifi since I have unlimited data but would prefer to use wifi at home. And i pay for the tether. I need it to work. Don't get why it is so flakey.
Any help or tips would be greatly appreciated. Humor is always appreciated. ;-)

Only SSL connections are loading

TL;DR
Upgraded Android to latest on T-Mobile, only SSL connections load. Also can't send MMS messages. Factory reset after the upgrade, still having issues. No idea what causes it, but rebooting the phone sometimes makes the issues go away for a while (might as well be running Windows). The issues seem to happen at random but all happen at once and don't go away once they start.
I have an odd issue that after a little bit of Googling, I haven't been able to find anything on (outside of app developers forgetting the internet permission in their manifest file). I held off on upgrading my phone from 5.0.1 AOC9 for a long time because I had rooted it right after the release and I just never got around to it when others confirmed they could root newer versions. Everything was working until I decided to use Smart Switch to upgrade from AOC9 to the latest 5.1.1 DOJC. After the upgrade I used Odin to flash TWRP and Unikernel for root and it worked fine for a few hours until I noticed I could no longer send MMS messages (receiving them works perfectly fine). I also noticed certain apps would tell me I had no network connection and I knew this was wrong because apps like Facebook were still working perfectly fine on 4G and my WiFi. Eventually I started clicking links from Facebook and noticed some would load and others wouldn't. It took a few links to notice that anything that wasn't loading over an SSL connection would give the message "This site can't be reached. $SITE refused to connect. ERR_CONNECTION_REFUSED"
After all of those issues started happening I finally got pissed enough to factory reset, forgot about FRP and had to factory reset again using Smart Switch. I flashed TWRP/Unikernel again and I'm right back to having the issues. Has anyone ever come across anything like this before? I'm getting frustrated enough that I might just swap out the sim and use my G3 for a while until I can sort this out. If there is any kind of log I can post that will help I can post that as well. I tried using adb logcat while attempting to open a site that fails, but I didn't see anything that looked useful. Just calls to my keyboard and chrome opening.
EDIT: Completely forgot to try pinging. I am able to ping any normal HTTP site from a terminal emulator. They're all reachable from my phone. I came across a post from a Comcast customer with a similar issue, although not for Android specifically. The work around was to connect to a VPN service, so I also tried this. Still no luck.

Problem accessing Youtube and Play Store

Hi, I desperately need some support as my device refuses to sign in in both Youtube and Play Store. I'm therefore unable to use both these apps. An error message keeps saying I'm offline and proposes to retry, but it simply never works whatever I do.
Issue has been going on since many weeks; I googles and tried many suggestions without any success.
Before I do a hard reset, has anyone an idea what this can be?
The amazing part is that my daughter's tab (Galaxy S2) is also having the same issue since some time! She has her own google account. What the heck is going on?
Thanks!

This may be an bug in the updated version of google play store or YouTube..Have you tried to sign in specific apps usning another google account you have..Also try to clear cached data of phone as well as clear data of those apps* you can also uninstall updates of those apps and force stop or disable them and after enabling again try to access*..Also might be network related issue sometimes weaken network shows such type of errors..Try to acees with high speed wifi or data with maximum signal..Even if problem exist then simply reset is last option for you..

Hi, I tried most of the solutions you're are mentioning, without any success. What I find interesting is what you wrote about weak network. I cancelled my cable connection at home some time back and using instead a 4G modem. Could that really be the culprit, knowing the coverage is medium? It sounds to me strange that such possibility exists, also I often go out and have full 4G network for hours sometimes and still it doesn't work. Interestingly enough, every about once per month it suddenly works, and I'm able to update my apps and also access my account in Youtube. It'll work for 2-3 days, until it's again the same bad. Really boring and would love to understand this issue better so as to possibly fix it. Thank you.

1)It's possible sometimes your networks proxy enforce your google id not to be sign in into specific apps you have mentioned and yes sometimes low network coverage also causes the issues like offline or sign in errors like please check network connection due wireless functionality limitations
2)I am curious about one thing if you have tried almost all the solutions found on google as well as your own, is it that much impossible for you to make backup of your current imp data and give a try to hard reset?? If i am not wrong, please give it a try because sometimes software glitches also causes the app crashes or network errors
3) Next thing sometimes your stock software gets corrupted due to some fatal malwares so many system apps as well as third party apps pretended to show errors like unfortunately process is stopped also some network related issue, so one solution you can try is to re-apply or update your current stock firmware..i.e. if update is unavailable you can fresh install same firmware version again on your phone which most of the times resolves the issue
4) As i mentioned in my first post you should give a try to any high speed mobile network like LTE or 5ghz band Wi-Fi which gives constant access to internet connection which probably help you to figure out exact issue i.e. with modems or connection your using or with your device itseld due to corrupted software
5)Please mention your device model no,country,your mobile network provider information so that it would be easy to figure out your issue

Thank you. Yes, a hard reset could solve it although I'd like to avoid it if possible. I will try ASAP on a solid wifi and see. I forgot to mention an important point: my daughter's tablet (Galaxy S2 pro) has got the same issue, and it started near about the same time like it did to me. She has her own Google ID, and she uses a different set of apps. Will report whenever I can test on a wifi.
My mobile provider is Salt Mobile here in Switzerland, and my Note 5 is a generic one bought in UAE. I run Dr. Ketan rom of about 8 months ago.

1)Ohhhk now i got, i assume you might be using Indian Variant with indian mobile network providers as per your username 'prerna'
so your device might be factory unlocked SM-N920C
2)So you should try on any faster network provider or incase wifi to check if problem is due to weak singal strength or specific with your device software integration
3) And i think you should give a try to dr.ketan's nougat rom which is based on latest nougat firmware which will might help you to overcome your issue as new base,new kernel will help you to get stable connectivity
4)If your running dr.ketans MM 6.0.1 based rom then download latest N5 nougat rom to flash
5)I know u might not new in flashing custom roms ad your running a custom one only from 8 months but once again be sure to enable 'oem unlocking' and 'usb debugging' options from developers option before flashing latest twrp version(Don't worry u can flash dr.ketans rom using any 3.0 twrp version ur running now but if latest version with stability and improvements available for your device then you can install it as per your requirement) if your running old one or before flashing nougat based N5 rom by dr.ketan

S6 Active on AT&T - DQE1 firmware giving me wifi problems. How do I stay on DQD1?

S6 Active on AT&T - DQE1 firmware giving me wifi problems. How do I stay on DQD1?
So I had been putting the nougat builds on My S6 Active from a post here on xda. On the DQD1 build everything seemed pretty good for me. Then one morning I awoke to see that the phone had automatically updated itself to the DQE1 build. Then the problems started. Every time the phone would go into lock screen and I'd re-open it, I'd get the wifi connection message. Also had all kinds of problems staying connected to wifi. I put DQD1 back on to do some testing. Problem is, it keeps updating to DQE1 overnight. I found 2 places in android to stop it from doing that but both don't seem to stop it. Again, it updated to DQE1.
Some have suggested that I freeze the update application with package updater pro. Before I go that route, what application or service am I trying to prevent? I got another app that is supposed to allow me to suspend applications/services but I can't seem to identify what app/svc I would actually want to suspend.

U open app ATT Smart WIFI -> to settings. and config app.
or disable thit app.
Now, check wifi again.

I've had the same problems. I'm hoping the suggestion from above me works.
