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:

*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

Okay so over the past few days I've been flashing a bunch of diff roms to see what I like. I've had a constant problem with getting mms to work on any of them. Well I was doing all of this from home and always had wireless to use for data, hence I used it.
Tonight, however, after flashing a few diff roms I found out I didn't have a data connection at all. Tried a couple diff cm6 nightlies and the blackmod of cm6, and after flashing the only way I can access the internet is through wi fi. Otherwise I got nothing.
Sooo, maybe my mms problem was just this all along or maybe not. Anyway, what could be the cause of losing all data connectivity. Phone says it's connected in status. And the widgets somehow magically update. But the browser, market,mms, etc don't work at all.
I'm gonna flash the 0.7 aospmod and see what happens. Any help you can offer is appreciated.
And yes, I might just be an idiot. Forgive me.
Just flashed aospmod v.07 and same ****. No data connectivity.
What gives? I feel stupid.
a guess
possible APN settings issue, did you flash back to a 2.1 sense rom, and try an Over The Air activation and update profile?
I honestly don't know but thats a guess... I use my phone with pageplus (verizon) and editing my APN settings is what fixed it for me.
Ruu. Started fresh.
Everything seems to be okay.
Thanks.
This happens on a lot of roms. I've found to fix it all u have to do is toggle on and off either or both airplane mode and moblie network.
I found having to open browser and put in my cell number b4 sprint data would work, also prl update works for me.

I had this happen to me (including all bars showing and things refreshing) and spent several hours working on it only to determine the only solution was to RUU and start over....but its faster this time around because you have nandroids....just flash one after you re root from before you lost data (if you have one) and if not, back up your apps and data with titanium backup or mybackup pro...
(I had tried all the things listed in the previous posts....not saying they wont work for you, but in my case, they didn't)

Hello All,
I have been in battle with Verizon ever since I first got the service with my Thunderbolt. The internet would run for about 15 minutes and then drop connection even though everything said it had an internet connection. Verizon has had me change out the SIM card, reboot the phone, reset to factory, made sure that always on data was enabled. I have used multiple different tethering applications such as PDANet and EasyTether along with rooting my phone and installing wifi apps. (they don't know about the root). I have been through 4 thunderbolts, all had the same problem. Internet would run for about 15 minutes or less and then stop working. Verizon checked out the network and said everything was fine. I now have a LG Revolution and am having the same problems again. So I know its not a phone issue. I read on here that turning off voice privacy can possibly fix this problem. So I did. I pinged google and at 13 minutes into it started to fail. It would time out or if it did successfully ping the time it took was above 3000 ms. I have a 3G connection of -82dBm (4G currently turned off for trouble shooting purposes) and a 1x connection of -90dBm. Does anyone have any other suggestions? Verizon help is useless so im going to you guys who are much more knowledgeable than they are. I have also tried this on several different PCs. I have to reboot my phone to get the internet working properly again.
Sorry about the long post but its all information you guys need to know.
Thanks,

Phone calls are like this on my phone. Its a call dropping fool. But, the signal doesn't cause it, it doesn't change. I think its the software myself. I've run log cat, and all i see is a message that says there was a signal change. I dobt know if its an instantaneous thing that i cant see happen, or if its a crock of shinto.

but my problem isnt with calls being dropped. Its with my internet connection.
Right, but its still over the 3G network. People are having texting issues as well. I think its LG's radio software, is what im saying.
Sent from my VS910 4G using XDA Premium App
i dont think it has to do with software because I had the same problem on four different thunderbolts. I also rooted it and tried multiple different roms and radios. So unless LG and HTC all use the same radios odds are thats not the problem.
Well, my Xoom runs fine on 3G,and it doesn't have a 4G radio yet. So I doubt it's Verizon.

I was thinking maybe there is something wrong with my account or sim card? The girl that set everything up originally was a complete and utter moron that did not know what what was doing.
temporary problems.
Earlier on when I got my phone I had intermittent connectivity issues, but toggling airplane mode on and off or a reboot usually fixed it...and for longer than 15 min, more like days. I'm in a 4G area now, but for about a month and a half only had 3G. Occasionally I still loose connectivity but both methods I just spoke of will fix it for the long term.
It seems very odd that it's not a widespread problem. It’s just so weird. I can stream several Netflix movies back to back without any breaks, even on 3G.

I run into this same problem while tethering whether on LTE or 3g. It runs great for a while, hours even, then all the sudden it will quit for anywhere from a minute to an hour or more. Sometimes a reboot will fix it. Interesting thing is I ran into the same problem with my old motorola droid. Make me lean towards this being an issue on verizon's end.
Does this occur when you are connected to wifi or only on 3G/1x? Have you tried testing in different locations with varying signal strengths?
Do you have the problem without root?
I'm wondering if this is an issue with your local network, meaning Verizon's network in your area. Since it happened on two different models and several phones, it would seem to indicate that it is an environment issue rather than a radio or other hardware problem.
I have a similar issue, but with text messages. I can send 3-5 text messages before it just chokes up. Then I have to reboot, or turn airplane mode on/off. Then I can send 3-5 text messages before it chokes again. I've done everything I can think of to isolate the problem, to no avail.
If anyone has a solution to his, please let me know. It's almost worse than not being able to make phone calls.
I also experience the Internet issue, but less frequently. It;s not my ROM, because I've used three different ROMs (including stock) and it was a problem on all of them. I saw on some other forum that it may be an issue generated by switching from a 3G phone to a 4G phone. If the VZW rep who setup your phone didn't do everything right, there's a "behind the scenes" setting that sometimes fails to get changed. The suggestion was to dial *611, describe the problem, and they should be able to fix it (though it may take 2-3 days).
I plan on trying this tomorrow, will let you know if I experience any changes. If anyone else has done this or wants to try it, post your results, and lets see if we can get this figured out.

Does not occur with wifi. Happens both at my house which has weak signal and also at my work about 20 miles away. At my work, the tower is practically in the parking lot.

This is almost certainly a VZW problem, whether they will acknowledge it or not is an open question. The only other things I can think of is a bad SIM card or incorrect programming of the SIM. The OP stated that Verizon swapped his out, so that leaves only the programming or the network.
Wish I had a better answer for you, bro.
My internet connection just started messing up with me today too. The internet will work fine with 4g and wifi but i get no internet connection with 3g only...
I have the exact same problem as the OP.
Really pisses me off. Want to throw vzw out the window and go back to a feature phone sometimes.
Vzw customer support is less than helpful. One will say your phones the problem, but why did I have the exact issue with my Incredible. Another will say its because I live in a fringe market area and we aren't really an important part of the network. WTF?
All I know is when I lived in Cincinnati everything worked fine. Moved up north and about 6 to 8 months later my service slowly starts sucking more and more to the point where I don't even bother looking up info on my Revo anymore.
I got my replacement LG Rev exactly one week ago to today. This one is all sorts of connection/rebooting issues.
Also unfortunately the update was already on my phone when I got, so no root for me
WiFI wont stay connected even if i'm 3ft from my router.
Phone will lose ALL signal and drop in to extend, and I'm only 1 mile from a strong 3g/4g tower.
Whenever i would pop it to airplane mode then back on, it would reboot.
I have 4 days before its been 1 month with this phone. I'm close to sending it back and getting the HTC TB or Droid 3.
In a test of patients I reset my phone to factory default, removed CWM and it updated to v6. I have to say the network connection was the most stable I have ever had it be but in turn the phone was not as smooth. Changing between screens had lag and was not as smooth as the original rom that shipped on the phone.
I have since down graded and re-rooted. The signal is not as stable either.
I was having same issue, especially with certain sites, including my own website for my business.
So far, what has fixed the issue, at least through Linux Network Settings, is setting the MTU to 1300. No other number has worked so great to date, but that seem to load everything and keep everything fast and quick with little issues.

EDIT: Upon further reading, I'm wondering if my reply was not quite on track. Is this problem on the phone itself, or via hotspot/tethering? It seems to be on the phone, so my reply might be way of course.
So today my data/internet 3g went down...I could receive calls send texts but no 3G verizon rep needed with my cell for a while kept going on how task killer and lookout was bad for my cell and was likely causing the problem...whatever I said and he couldn't figure it out do he hard reset...guy mentioned saving apps to SD card so here come
My noob question how do I save my apps to SD cars? And had anyone had 3g loss issues like I did today?

Don't bother with the hard reset. I tried it, it didn't work. I still lose 3g frequently.

I am losing 4g/3g pretty frequently now as well. When it goes off, it doesnt seem to want to come back - but a reboot does it.
The only thing I have kinda noticed is that if I am wifi, then leave the wifi area (thus disconnecting) it tends to drop the 4g as well and wont reconnect. I'll have to test this some more, but thats all I can tell so far.

I am having the same problem as you, between changing back and forth from wifi to 4g and loosing all connectivity besides voice. My girlfriend has a bionic as well and has no problems whatsoever. I also do have lookout installed and she doesn't so I will try uninstalling that to see if it help and check back. But it might be a faulty phone since my girlfriend is having none of my numerus problems. dropping 3g/4g, wifi super slow when my other verizon phone is having no problems with connectivity with 3g/wifi. randomly locks on me while Im using the phone and the timeout is set at 10 minutes. And one time it totally turned off, not even just a reboot. Anyways back to the connectivity, I will try uninstalling lookout and report back! Hopefully that works.
i think verizon is working on their towers and 4g as ive had alot of data issues too until yesterday when it seemed to resolve itself.
Hmm so it may be lookout... Well I installed it again so let's see how it goes on the wifi speed I had the problem the first day I connected to my home connection but as of late its all good. Is anyone else running lookout? Post what up with your bionic running lookout. The rep did say it might be just my cell in particular but seems I might not be the only one I guess will update as day goes

Ive been having the same problem with 3g. I stay on wifi most of the time but whenever I do have to leave the house or work, I will lose 3g at first.
At first, the only way I could find to fix it was with a power cycle. Since then, Ive discovered that turning on and off airplane mode seems to do the trick.
Next time you guys are having trouble, try toggling airplone mode once or twice. That has worked for me everytime.
It's not convenient, but I'm sure there is a fix in the works.
Oh nice i had tried to toggle airplane mode but just once ill give that a shot if i loose 3G again so far last night after hard reset and as of this morning everything running good even with lookout running... Might not even be lookout
Sent from my DROID BIONIC using XDA App
It is definitely not lookout. Or any other useless battery drainer. Toggling airplane mode, rebooting, etc do nothing for me. It decides when it wants to come back.
I have had the same issue once today. It was alot more yesterday.
If it keeps up, I'll be taking it back.
Sent from my DROID BIONIC using XDA App
Airplane toggle hasnt done the trick for be. Just as a shot in the dark, I removed juice defender. I do not think that is the culprit here, but anything that controls my radios is suspect at this point.
Huh i just thought about something yesterday in the morning i saw a post Bout someone developing an fm radio app and thinking about it now after i installed it thats when i started having issues... Just throwing that out there i didnt even use it though but i havent re installed it either so i dont know if that even the problem

I am not rooted yet and haven't applied any hacks/tweaks. My data connection drops whether Im in a 4G or 3G area, automatic or CDMA only.
Seems to happen randomly although this last time it happened after unplugging the Bionic from charging. Toggling airplane mode restores data temporarily. Verizon will probably issue an OTA update soon to fix this but I hope it doesn't break the root exploit or I won't install. Once we have a working ClockworkMod recovery the ROM chefs should be able to fix this...
I heard the verizon rep say that his bionic did the same thing when it was charging via computer because it was in debug mode so you might want to look into that if you charging via a computer... Maybe?

I've been experimenting a bit today and it seems that anytime my phone switches between data types, the signal goes down until a power cycle or toggling airplane mode. It happens the most when my phone goes from wifi to 3g. Whenever I leave my wifi area (work or home), the phone fails to find a 3g connection. This also happens if I manually turn off Wifi. If I've been on a wifi connection for a good amount of time and then disconnect the wifi, the phone won't find 3g.
Not sure if it has to do with my settings, but figured I'd mention them here.
Most of the time, I am in a 3g area so I keep my phone on cdma only unless I'll be traveling to a 4g area. Not sure if changing the settings to CDMA/LTE will change anything but I'm going to try that next.
Anyway, this is definitely something that needs to be brought up with both Verizon and Motorola. The more people who notice and say something, the faster we'll get a fix...at least in theory.
I switched to Verizon from Sprint and I'm not going back. Despite the issues, Verizon's 3g has been 5-6 times faster than the 3g I got with Sprint. Besides that, I should have 4g by the end of the year and the 25 Mbps down I am getting in surrounding 4g areas is killer. Just hope my switch to Verizon wasn't in vane. There isn't another phone on their network that even looks halfway appealing at this time and I can't wait a month for the Vigor or anything else to come out. Plus I like motorola build quality. So, let's hope a DEV or Motorola and Verizon gets this fixed on the fly cause its definitely an annoying issue.
Anyhow, if anyone finds a workaround or solution to this better than toggling airplane mode, please let us know. Starting to get tired of pulling out my phone looking for something, only to find out that I don't have data.
Hi just got the 7 plus.
I connected the phone using WiFi hotspot of my main phone.
When I try to update it during setup, it looks like it's going to start then it says waiting for Wi-Fi. I skipped that part then went on to set up my email using said wifi, which worked.
I then came back to update the phone and it keeps giving me the same message.
I switched the SIM card and downloaded some apps because it won't even download any app, and downloading the update won't work that way as it requires WiFi.
Browsing works though as does YouTube and the Reddit app am using while on the hotspot.
Is there anything I can do to get the update on my phone?
Phone was bought from UK though I'm in Nigeria now. Don't know if that matters.
Unchecked the metered connection on the Nokia so now it downloads apps but still not the update. Keeps giving me the same message. The model of my phone is TA-1055
Is there anyway I could get the update?
Thanks in advance.
