[This is probably only UK related but may be relevant in any Vodafone region]
OK, so Ive posted here and on Modaco a number of times regarding an issue that was driving me nuts. Whenever I moved out of range of a known WIFI ap for more than a few minutes, wifi would just turn off, and not turn itself back on when I came back in range. I would have to manually turn it on before it would connect.
Well, for the past week I have been looking at the various apps on my phone and looked at anything with Wifi permissions and uninstalled each one by one to see if that solved the issue. Nothing changed until I uninstalled the My Vodafone app. Turns out that the issues with my phone auto connecting to BTOpenzone APs are related to the wifi off. The My Vodafone seems to continuously tries connecting to BTOZ APs and after it fails a few times it switches the wifi off it seems. Since its removed my phone has been working normally.
So there you have it. This will mean nothing for most, but hopefully someones sanity will be spared with this info.

I don't have that app, but thanks for letting us know.
My wifi has no problem so far.
Are you sure its not setting your AP to ignore due to poor speed?

I had noticed that as well with my wifi settings. I changed it right away.

Yeah, this stopped happening for me too after uninstalling the My Vodafone app. Maybe that's one of the reasons why they've pulled it from the Android 4.0 marketplace.

i had that problem, just realised the problem had stopped when i got a replacement Nexus and it didn't re-install, thanks

I have the same problem OP had but i don't have that Vodafone-app (though i have a Vodafone sim)
How do i change that AP (don't know what that is) setting?
So I have it set up to check for the cell tower...and turn my wifi on and if I'm at home change the lock screen off/on
I'm having an issue where the wifi keeps turning off....and I don't know if its a issue with the gs2 and ill have to set it different...or an issue with my wifi or an issue with cm9??
To test to make sure it was not a connection issue with cell tower or tasker. I set it all day today to instead of turning on wifi to turn on Bluetooth when I'm connected to the same towers..and if my Bluetooth connected to my home computer to change the lock screen and didn't have any problems with it.
What can I use to monitor what happens that causes my wifi to turn off?
Tasker. I'm not sure why but I tried a similar setup after turning wifi on or off a few times it gets buggy.

Incase you still want to set it up like that its a no brainer but it took me a few days to think pf it and then I slapped my forehead in a "duh" type manor... I set up a profile so the cell towers by my house turn it on... Then I set up a profile pasted the same towers clicked to invert it.. So if its on any towers besides the ones by my house.. Had it turn them off.

How has this worked for you? I was experiencing this issue as well and have just implemented this new setup. I was wondering if it was working out for you since you made the change or if I needed to keep searching.

It works amazing! Recomended for sure. Sorry that took a while for me to get back to you.
I obviously have the Sprint S2, and I continue to have issues staying connected to my home wifi. I have no problems connecting to other wifi networks. It will connect, then after a few minutes, it disconnects, even though it shows I'm still connected in my notification bar. I've searched high and low. It seems many other people are having the same issue, but no one seems to have a fix. Anyone here know of a solution? Thanks in advance.

I'm thinking it might be the router because I've not had problems with any other networks. I just ask because I've noticed that other people have had the same issues with this phone. Here's a screenie of what I'm running. Thanks

So I finally figured out what the issue was. A lot of mobile devices have a hard time connecting to highly secured networks such as wpa2. If you have a wpa, or wpa2 protected router, you can only use numbered passwords. Up to 10 characters. I tried this, and it's the only solution I found. If that still doesn't work, change your wpa2 security to wpa, with a numbered password only.

Try changing the channel on the router, force it to a different frequency B or G only also.

if you have to use numbers and only 10 chars, it sounds like a router config issue. sounds like you have WEP on rather than WPAx
Wifi busted
I actually have the same issue. Wifi worked flawlessly on gb. On ics every time phone goes to sleep it drops, notification says connected. Toggle wifi off and back on works, phone sleep back off. Tried wifi never, only when plugged in. Switched to 2.4 ghz only tried 5 ghz , too. Linksys ea4500 wpa2/aes(setting) brand new. None of the numerous other devices in the house have any issues. Speeds seem awesome.
Tried factory reset nothing works. Even got sprint to get me a new phone, still no solution other than going back to el29. Currently, running fi03 stock rooted. Scared to try latest fi25. Any other suggestions would be great.

still sounds like a router compatibility issue. See if it happens on a different wifi.
The only way i can successfully stay connected is if there is no security or wep is used. Same router nothing had changed. Again worked flawlessly with EL29 update comes to FF18 and it no longer works. Sprint has said it is a known issue with ics on samsung and htc but no fix. Don't want to give up my security just to use wifi. If i roll back to gb everything works again without changing anything in the router. So i don't believe that is it. Plus, i know all about router settings not a noob. I beleive it to be something in the phone update.

My wife runs fully stock newest release and its fine. Try a different router. routers can have compatibility issues with devices. Also you say "its a known issue" but can you give a source?
I'm not saying its router settings. I'm saying it can be a compatibility issue between router and phone chipset.

I was having this issue on fi03 and fi25. Tried different modems, kernels, routers with no improvement. Downloaded WiFi keep alive from the market and use workaround #1 and it hasn't been an issue. Doesn't answer the question but it does solve the problem. Hope it helps. Good luck

I guess i should've mentioned there are 2 of the same phone in the house. Wifi works fine on the other device. Source? As in sprint tech support told me over the phone it was a known issue with samsung and htc devices, not all are affected. This is why sprint decided to replace my old non working phone for the new one.
Not sure why of it were truly a setting inside the router why would one work but not the other? Seems highly improbable to me, just saying. I do appreciate the feedback though.

So two of the same phones. One connects and one doesn't. Interesting. About the tech, seems a pretty wide declaration of an issue. samsung and htc phones. lol. There are a ton of those and its a 'known issue'. If it were a known issue, they would have it tied to a specific phone and wouldn't say 'well err um some phones work and some dont'. lol. Anyway, I don't usually trust those techs.
Back to the issue. If one works and one doesn't... Then it sounds software or still compatibility type issue.
Have you tried these things? If it were me, this what i'd try....
1) I'd reflash your phone's ROM fresh and try again. Full wipe. It's possible the update boinked your wpa_supplicant settings.
2) DHCP: stick a static IP on your android and see what happens. (dont confuse this with a static dhcp lease) DHCP does some interesting things on android phones as far as wakelocks and such.
3) In the router, turn off all the bell and whistle crap... Some of these routers have things like 'afterburner' and things like that. It can cause issues at times. Keep track of what you turn off and obviously if it don't work, turn it back on again.
EDIT:
This is interesting as well. Your not the only one.
http://forum.xda-developers.com/showthread.php?t=1847889&page=4
Try the things I posted but ultimately, you may need to just flash a different ROM version... Doesn't mean you need to go all the way back to EL26. At least you know its not only you...
So I initially called Centurylink, and they told me to change security settings. I did this, and it worked for a short period, but then dropped again. I couldn't figure out why this kept happening, and it had become quite frustrating. Then I realized that I had created a new network with a personalized name and password. My laptops connect fine to that network, but my phone won't, so I connected to the initial network created by Centurylink, and have had no issues. So I can suggest trying that as well. Hope that helps

Same issue for me too, since moving from gb. Running S710.10 S.FI27
I see this on both of the WIFI networks I connect with regularly. Home is worse. Every other device at home, including phones, PCs, TVs, tablets: mine and guests, can connect and stay connected just fine. My Epic 4g with ICS can't stay connected to save it's life.
I'm about ready to try the less complex key route, but not my 1st choice. Any other ideas?

different rom? mine never ever disconnects running cm10.
Set up both home networks using WPA/WPA2-PSK and no issues. Did have issues at work with WEP so perhaps that's the offending solution? If so try TKIP instead.

Gone in FI25/FI27 - looks like it won't be re-appearing until JB, at least if FI10 was accurate in this respect.
I have no signal on my galaxy nexus. It just started doing this today, haven't had a problem for 3 months or so. It just started today, and once in a while there is a little R above where the signal bars would normally be. How do you fix this?
The R is for roaming and just go to settings then mobile settings then click on system select and click on home only and also click on network mode and just click on CDMA/EdVo auto and that should help it to not roam and stay on sprints signal hope that helps ..let me know if u need any other help and also make sure u updated to latest PRL

Mine did the same thing too -- lost signal - Google GSM play store phone that was less than two weeks old.
After few reboots trying to diagnose the issue, the IMEI changed to UNKNOWN in the "about phone" -> status
/factory was intact and undamaged - a backup of /factory - showed that none of the files had changed. The radio appears to have failed..
Called Sammy and got replacement cross-shipped - and sent the broken one back..
Got a new Sim card works fine

Mines done this several times and it always took about two reboots to get a signal again. It said I needed to insert a valid sim card...
Sent from my Galaxy Nexus using xda app-developers app
Even without a a sim I used to get bars and "Emergency calls only" - After it flacked out, I would no longer get any bars.. when I tried to search for networks it would error out immediately. I tried three different sims, none of them were recognized..
Once in a while, my phone will loose data connection. The 'data icon' in the status bar, turn from blue to grey and the only way to get data working again, is to reboot the phone.
Had it happen a couple times now. Airplane mode toggle on/off works to fix it.
Mine losses connection when I leave a WiFi network. Also here and there it looses signal so bad I have to go into airplane mode and back to land mode.

take out your battery and then restart your phone. if that does not work. check in your network settings and make sure you are on the correct network for your carrier. if that still does not work, go to your local store and see if they can warranty you out a phone or check your settings

It's not neccesary to take out the battery, a restart of the phone is enough. It's just an annoying problem.

I understand that but there has to be fix right? As soon as i reboot the phone it works but it seems like whenever it changes cell towers signals it locks up again. Crazy thing is all the signal bars on my phone are full green, but have no data until i reboot.
So this has happened to me at home and work but it's not consistent. Some times when I try to connect I get a message on the WiFi connect that says "Network disabled because Internet connection is slow" (see picture). Any idea what criteria is used to determine this, and is there a way to over ride it?
I'm at work right now and I just got kicked out wifi due to too slow lol.. but at home I have not got it yet.. maybe too much people at work using the wifi network. .
I setup my home network to have separated name (SSID) for 2.4Ghz and 5Ghz Network.
When I connect to the 2.4Ghz channel, no problem.
At the same distance, like 6 inches away from the router, when I connect to the 5Ghz channel, my 2 Galaxy Note 3 shows the same "network too slow" error and it will drop the connection.
This is one of the many reasons I returned my GSN 3
I also experienced another WiFi error.
At work, I can connect to the WiFi network with the WPA password provided, on my HTC One with no issue whatsoever.
When I tried to connect to the same network using the Note 3, it keeps telling me I have to "sign-in", when I click on the browser to "sign-in" (like those Free WiFi you can get at the hotel), there is no sign in page (because there is none) and brings me right to Google.com.
After that, the connection will last for 30 seconds or so and drop off.
The one I got initially and the replacement, both have the same issue, and I did inform T Mobile before I return them back.
4.3 problem? Samsung's problem? I don't know... All I know is I will wait until they resolve all these before I will reconsider getting this phone.
I spoke to them on same issue. Got new phone and they working on updating the WiFi drivers.

Here is the fix for this it worked for me try this....
Go to wifi advanced settings lower left corner then uncheck auto network switch. Then check the box that pops up that says don't ask again. This should fix your wifi connecting issue...

So far yes. Not a 100% sure though because the problem was not consistent. Sometimes it would connect sometime give the message. So, I'll keep you posted if it comes back.
Not trying to say your post isn't serious enough but we all who are having this problem on a consistent basis need to make a thread about this and just not take anything for an answer, but to give people somewhere to complain about this & hopefully bring more attention to this because there is nothing that is fixing this issue. The only thing that will fix this is Samsung or a Dev on a custom ROM hopefully. If you uncheck the options in advanced settings, it just stops the pop up from coming up telling you the connection is to slow & dropping you, after unchecked it dont drop you but while still showing you a full connection it will not do anything data wise, connect to the internet, switch to a different site, no facebook, no twitter, no market etc..... Nothing, you dont get dropped you just cant do anything. I hope my anger dont make anyone think Im arguing with anyone in here and their opinions, we all have this problem and are trying to help eachother, im just poitning out that those who are thinking this is fixing things its not, its just stopping the pop up. I am very frustrated this is happening on a brand new phone i waited this long for and paid as much as i did for. There should be a freaking petition started for this cause its just wrong.
Works fine for me my wifi never disconnects now after unchecking auto network switch and always scanning... Idk what to tell you guys that are still having the issue because I had the same issue when I first got the phone too...
Maybe try forgetting the network then reconnect after unchecking those settings and reboot...

Not all phones are created equal. Samsung needs to change the wifi drivers on the phone or a dev needs to take note 2 drives and add them to a custom rom.

I posted this in a different forum also but figured id post it here to. I just got off the phone with Samsung & they told me its not a major reported problem, wtf, lol? Everyone i know who owns this phone has this problem with it sayin internet connection to slow and booting them off, even with full signal. Im on my 2nd phone now & have the same problem. They tried telling me to go in to the wifi call settings & turn off wifi calling preferred, & i said why? Even though it's checked I have it off. I said seriously? what is that going to do for a wifi signal problem, lol. It's not my wifi calling it's my full wifi signal. I can tell this is going to be a huge problem & im returning my phone, 3rd time now, for a new one today, if i get the same problem, almost positive i will, im sadly going to have to return this phone & just get a refund instead. & that would really suck. Maybe i'll try a black one, but im sure it probably happens on that one to, lol.
I have been having this problem also. Turning off "Auto network switch" in the advanced network settings allows the phone to hold on to the connection, but it is completely unstable. I tested the connection using iPerf and it was all over the place. I can post screenshots when I get home later if it helps anyone. Samsung definitely needs to step in here.

Samsung could careless about us. They sold the phone to TMOBILE not us. Or whatever ur using. Everyone needs to complain to the big 4 major company. Then if they get hit hard then they can light a fire under Samsung butt.
