[Q] Wifi Keeps turning off - Vibrant General

This just started this morning
If I turn on Wifi I will get a dialog box for a few seconds that says "Unable to scan network" followed by "Unable to save network"
The phone is rooted, has clockwork mod, and I have changed to the Captivate Camera. Those are the only mods on the original firmware and kernel. I have rebooted the phone and it still happens. This is quite the problem for me, any suggestions?

On the plus side, I did a nandroid restore and now its working fine.

I had the same problem and found that the problem seems to stem from Allshare. I used it briefly and disconnected from WiFi, later that night, I enabled WiFi and had this problem. Today I opened Allshare and it prompted me to turn on WiFi, I was redirected to the WiFi menu and attempted to turn it on again. Of course it failed the first time, but I repeated this process of opening Allshare and pressing "Back" when it tried to redirect me to the WiFi menu. Doing this two or three times somehow managed to get my WiFi finally to recognize and now it all works. I would say, that if anyone is to run into this issue, I think it's Allshare related. This is what I did to fix it, hope it helps.

I dont use allshare but I do recall accidentally hitting it yesterday before it happened. Worth testing to see if that does it.

YouTube Not connecting Problems

Hey Everyone,
I currently running Artemis_v100_WWE_210_23563 on my HD2, everything is going great except the YouTube app. Every time i try to play a video it seems to state "Connection failed. Please try again." only while I'm connect to wifi. Seems to work with my EDGE though for a little while and then it keeps showing that message. I've noticed if i hard reset my phone, it works amazingly for a good hour and then, if i trigger the wifi off, and use EDGE it starts causing issues, and when i try to re-enable wifi and use YouTube, it fails and never work again. Every time i hard reset the phone it seems to solve the problem for a little while, and then it goes back to the usual message.
I did not install anything on the phone when this occurred, and also turned off my network and only had wifi and its not working. It will work for a while like i stated with no network off immediately after i hard reset my phone but after i turn off the wifi and turn it back on it doesn't seem to work.
My internet and all other things work on the phone perfectly fine. Has anyone encountered this issue?
Current YouTube Version is 2.6
Anyone got any ideas?
anyone got any ideas yet? i update and downgraded my rom and installed the new rom V11 and still occurs, works for only a little while and now it doesnt
my does the same thing i want to know why too

I had this same problem... I had to delete a proxy registry entry for it to work correctly! I forget which one... Do a search for it and you should find it here in the forums...

Wifi wont stay on

When I go into the settings to enable wifi I get the following messages back to back, either one can show up first:
"unable to save the network"
"unable to scan networks"
When this started the phone was not rooted.
I rooted the phone in an attempt to fix this.
I deleted /etc/wifi/wpa_supplicant.conf after backing it up.
This fix was suggested in the EVO forum, however it did not work for me, also the wpa_supplicant.conf was not recreated, and I was under the impression that it would be.
Has anyone had this issue and fixed it without doing a factory reset?

Now that you are rooted, i would say do a nandroid backup, then do a factory reset to see if that fixes your issue, if not, then you have a backup to restore to incase it does not work, if it does, then your good to go, if not restore and you are no worse off.

How do you do a NANDROID backup? Using Koush's recovery image? I saw initial unstability issues so didn't bother with it. I'm still hoping to see Amon Ra's recovery.
oh jeez i'm glad this thread is here. I have the exact same problem now. I don't remember anything significant enough to screw up the wifi, but I did use XBMC and Allshare as a trial run and it worked fine and I was amazed.
The next day the wifi is gone and 'unable to scan networks' gets on.
Can somebody help with this issue?
I will nandroid back soon and see how it goes down.

that is a link to the how to, just follow the first post, once you have clockwork recovery installed do a nandroid back up through ROM Manager,(if that is the koush recovery you said you had your set, just install the app) try a factory reset after backup and see if that fixes your problem, if it does then your set, if it does not fix it, then you can always do a restore and it will put your phone right back to how you had it when you did the back up.
Just ensure that you dont partition your sdcard with the rom manager, it will wipe your whole phone internal sdcard, not the external one, you should have no reason to do this anyways, just wanted to let you know not to try for fun. as it is not one of the steps to backup or restore anyways.

thank you for that. i'll go try it out
None of that works. Does any developers or anyone with some experience have any advice or fixes? Much appreciated.

I'm pretty sure it had something to do with Allshare or XBMC. I think it has something to do with the phone having to scan a network for other devices to obtain indexes. When I was messing with allshare, I disabled the wifi in the middle of the phone attempting to scan my network for my media servers. That's the only thing I did, so it's the only thing that could have caused my issue. When I opened allshare again it asked me to enable wifi, I received the error a couple of more times then after a few times it fixed itself, which led me to believe that it was allshare that caused the issue to begin with. I'm hoping that samsung is aware of this bug.
Same issue, first time I restored a Nandroid backup to get things rolling again. This time I was testing a new DLNA server at home with AllShare, since then Wifi wont stay on. I have sent a message to Samsung support about it. Rebooting doesn't seem to help, not sure how to do a workaround.
Best thing is to go into AllShare, make sure Wifi is on, wait a few seconds and then go to home screen. Usually after a few tries the Wifi setting will stick.
Like I said, all I did was to try and go in and out of Allshare back and forth between the Wifi application and enabling/disabling Wifi. After a few tries, it magically enabled successfully and worked. I wish I had a better fix or better advice, but all I can say is that I just had Wifi disabled, attempted to launch Allshare, Allshare told me to enable Wifi, so it automatically took me to the Wifi settings menu, I enabled it, received the error, went back to allshare, it sent me to settings again, I enabled wifi again and immediately pressed back to get back into Allshare, at which point I just bounced back and forth between the two, hitting back immediately to get back into Allshare, and somehow Wifi worked. This leads me to believe that Allshare didn't finish "something" with wifi, so interrupting Allshare in the middle of a network scan is bad.
already returned one unit to tmobile because of this issue a couple weeks ago had no idea it was related to allshare. makes sense i was using it to try to stream to my xbox the day before
Looks like a pattern to me!
Also, if you are using Juice Defender, you may have a setting that is turning off WiFi.
Fixed for me
So I had the same problem. Not with allshare, never use it. Just randomly stopped working. Anyway, follow the link below, it fixed the problem. It does require root and editing the conf file rather than deleting it. I had a missing } from the end of one of my entries for some reason. I removed all of the saved ssid's and put in the missing } to the end of the t-mobile entry and no more problem!
I can't post links so change the below hxxp to http

I'm rooted, deleting that file worked fine for me and it was recreated (the one early in the thread)

It's worked . Thank you so much.
none of the "fixes" posted work. im bone stock, running eclair. same wifi errors as the op. The phone is to be used as a wifi only device, since the sim is not active. is there a real fix for this?
This is helpful information. thanks.

[Q]Network connectivity & Dexter's mod 1.41

Hello,
I would have posted this under the development posts but the forum won't allow me to...grrrr.
Anyway, I am using Dexter's mod 1.41 with the display settings fix also installed. Everything works great.
Except...I keep getting network errors whenever I try to download an app from the official marketplace, I also get them when sync'ing my dropbox, trying to download from the appoke apps store, signing into twitter, and a number of other apps. My browser works fine. Sometimes I can reboot and it starts working fine and then a few hours later I start getting the "network connection error has occurred" message from various apps again.
I did try reinstalling 1.41 & doing a complete wipe/restore after & still had the same problem eventually. It worked fine for awhile as I was able to go to the marketplace and download all of my apps again.
Anyway any ideas?
Thanks in advance!
i might ask if your network problems occur after the tablet was recently asleep. it seems, at least latest stock, that the power profile is set to sleep wifi/network connections when the display is off.
you might want to wait 5-10 seconds after waking up, or i suggest putting the power control widget on your homescreen and tapping the wifi button twice to re establish your network connection if you're getting network errors.
worked for me when i had download/network errors.

Yeah Forgot to mention that, but no its random when it starts happening. But definitely not just when it has been just woken up.
Nevertheless I am going to try what you suggested. I couldn't at the time when I wrote the post as it wasn't working. I turned it off and removed the SD Card, mounted it over on my PC, then copied your recent ROM update as well as Elocity's most recent firmware update, put the SD card back in, tried to reboot into recovery mode but for some reason it went into a normal boot. When I unlocked it, for some reason was asking me to sign into Google just as if I has flashed it but I definitely didnt. I've done that a bunch of time, this was definitely a normal reboot with dexter's 1.41 mod still installed. I canceled out of the google login after waiting 10 min for it to connect to Google's servers. (it was connected to my wifi network or at least I had the icon with the bars indicating I was connected to wifi) When I got to the main screen it started working normally. I went onto the market and downloaded Angry Birds Rio. Plus there were a bunch of updates for my other apps. So it is almost acting like I was not previously signed in with my google account, except that I did not relogin since I canceled it before finishing. Also I dont imagine that Dropbox would have been affected as it has its own login. But that is working fine too once I re-logged in.
It does seem to be intermittent. If it were the "not connecting after coming out of sleep mode" issue wouldnt rebooting fix that when it happens? I try that everytime I get the network errors and it works maybe 25% of the time.
Thanks for the response!
Did the 1.41 install and three patches also. Display still FC all the time. other then that works OK!.

[Q] Wifi isn't turning on/ not working properly

So i remember that i just rebooted my device and next thing i know is, wifi is stuck with 'WiFi is turning on'
Things i have tried to fix it : factory reset, hard reset and when none worked, paid a visit to lg service centre where it started working automatically. Came home, worked just fine but for 2 days.
Now it's been a week. I even flashed stock rom thinking it might be 4.4 rom issue. And nnope. Sane issue. So i guess that means is isnt software issue.
BUT here's what happens. Same modem, mother's galaxy mega2 connects, her laptop connects. I today tried connecting my phone to her phone's hotspot and it connected in first try. Confusion is, i don't know if it's modem that's faulty or phone ( idk if software or hardware )
Also, i noticed when i try to turn on wifi now, it shows no connection available and the wifi icon in drop down menu keeps blinking without being blue. I think it should just turn blue even if there if no wifi to be detected. Sometimes it stops blinking and doesnt turn blue still
It's so confusing
Any help will be much appreciated !
hi, it has almost been two years, did you fix the problem meantime?

WiFi unable to turn on

So this morning my WiFi was working just as usual. But after that I went out so I turned it off and when I return home, my WiFi isnt working anymore. Its not that it wont work completely, but it keeps connect and disconnect. I just can't use it. After an hour I'm going out again so I turned off the WiFi. I was so annoyed by what happened so I decided to play with the WiFi toggle. Guess what, it wont turn on. When I tapped on the toggle it slides to the right remained greyed out, and stucks there. It will not turn on. I rebooted it many times, it worked for about a second then it stops working again. I tried to find out if it was software problem or what, I rebooted several times, disabled root, reflashed ROM, cleared cache, but it still wont work. I even factory reset it by clearing data and caches and reflashed my ROM but it still wont turn on.
Then just now I did a few Google and found out it may be hardware problem and many solved the issue by whacking it at the back. I tried it it worked for a second and the problem comes back again. Then I suddenly remembered that I heard some shaky sound from the upper part of the phone when I shake it. I noticed the sound long time ago but I didnt bother. And I did some sports this morning with my phone in my pocket so I think its the wifi antenna contacts.
Okay assuming it wasn't a hardware problem, is there anything I can try to be more sure that it's a software fault? I did factory reset from recovery. And is that shaky sound a hardware bug or it's normal?
Update: I can't turn on Bluetooth too so it's definitely a hardware problem since they share the same antenna. More over I saw this line in logcat thus making me more sure it's the antenna

Yes it's hardware.
