I'm running the official BTU 4.3 release on my I9505
I've noticed two issues with 4.3
a) Wifi
From time to time, perhaps daily, my phone loses connection to my home wifi. I get a notification which says something about being disconnected -- don't remember the full text. When I click on it I get taken to the list of wifi networks and underneath my local wifi network it will say "Sign-in is required".
It may be working as designed - checking my newish BT HomeHub 5 I can see the PPP session recycled twice overnight. Oddly this was initiated by upstream admin according to the logs, not a vdsl failure.... since the hub will intercept pages when ppp is down it's possible this caused the confusion
b) Security policy
I sometimes see a notification that an app required access to system, but didn't have permission - yet when I click on the notification I get taken to a full list of apps -- how do I find out which one was trying to be naughty?
The WiFi problem can be quite annoying.
I think this is not an improvement over the previous functionality.
The idea seems to be that as soon you have to manually log in to a WiFi network Android switches to the cellular connection to make sure you are always connected.
The thing is that at my work place this means every time I get somewhat out of range of WiFi (elevator, toilet, staircase) and walk into range my WiFi stays disconnected until I remember to reconnect it.
I only have to actually sign in once a day, but as Android thinks it is a network you have to sign in to it will not automatically reconnect to that network.
Meanwhile the phone is using up my data allowance....

The issue I have is that I live in an area with minimal mobile coverage so have to rely on wi-fi connection when at home. Just today my HD2 has started acting up with an issue that I have experienced previously. When I try to update weather, stocks and other apps that require connectivity I get the error message about the dial-up modem being disconnected - the cause is fine as I have no signal but I don't understand why these apps are not swapping to the wi-fi connection. Browsing the internet is fine as is the YouTube app but all others (including email) are failing as they are trying to dial-up.
I have done some experimenting with mixed results:
1) If the phone radio is off (aerial followed by an x) - then the phone will fallback to wi-fi and applications that require connectivity seem to work.
2) If the phone radio is on and it is trying to find a signal (aerial with 3 dots cycling) then it will not issue the dial-up disconnected error - instead it will try to connect but then either time out (for apps like Omarket and Sky Mobile) or will work with mixed results (stocks and weather - although it only updates locations other than my location).
3) If the phone radio is on but there is no signal (aerial followed by exclamation mark) - then I get the dial-up disconnected error on apps that require connectivity (with the exception of Opera and YouTube).
Does anyone have any thoughts on what causes these inconsistencies and if there is a way to resolve them? When I had this issue before I did a hard reset which seemed to do the trick although with hindsight I am not entirely convinced whether it made any difference - especially if Apple's excuse for their iphone4 signal issue is to be believed (i.e. at times I could have a signal even though the phone is indicating that I do not have one).
I presume in the real world i.e. one where one has decent mobile coverage - this issue is unlikely to occur or certainly less obvious to spot
Hey,
If you set up your dial-up connection as part of your WiFi connection ( ISP or Work) and then set "programs that automatically connect to the internet" to the WiFi connection the automatic program will no longer try and connect if you are connected by WiFi.
go to settings-menu-all settings-connections-connections and add a new modem connection to your Work network. You need to get the settings from your service provider or copy them from the existing data connection.
once done, got to advanced and select networks and choose the work connection for programs that automatically connect.
that should help

So in short I would have a single config that contains both the wifi and mobile settings as opposed to the two separate configs that I have at present. I will give that a crack and see what happens.
Thanks
I've noticed that my [rooted] Vibrant frequently has trouble connecting, or staying connected, to WiFi networks.
At first I thought it was specific to my Verizon Actiontec WiFi router, however I've also noticed this at my office, where we use Motorola routers, as well as a few other locations that I frequent.
It's still possible that its a site-specific problem, but, less likely as I'm seeing this in a few locations.
Symptoms:
I configure my phone to connect to X network.
It successfully connects and all it fine.
I get out of range, it no longer sees network X and disconnects.
Some time later I return to my previous location and expect that in N seconds/minutes the phone will automatically reconnect.
A considerable amount of time passes and I notice it's still not connected.
I check the wifi settings and it days connection unsuccessful.
I tap the network, click connect and it works.
I've also noticed this after connecting to a network and the phone goes to 'sleep' or into an idle state. When a wake it up, it doesn't always automatically reconnect.
Anyone else seen this?
Any suggestions?
Many thanks.
i've had that problem. i am not sure what it was because I was rooted and Ryaned. I got sick of all the stupid lil bugs and had to wipe format and unroot. Now that I am back to the original condition, theres this sense of comfort knowing if something buggy happens, it's not "my" fault.
Thanks for the reply.
I noticed this prior to rooting and 'Ryan'ing'.
The capacitive buttons don't work all that well from time to time - specifically the Home button so maybe I should just exchange it. I'll call TMO tomorrow to see what they say.
We have a Windows box with a wifi dongle and we're having an issue when a customer with a GS4 running Android 4.3 connects to it. The connection and DHCP negotiation work correctly. Once that happens we begin pinging the phone twice per second*. The phone answers the pings for about 3 seconds, and then never answers a ping again. The phone screen is not turned off. The user hasn't left the mobile app, hasn't killed any tasks or anything like that. Does anyone have information on why the GS4 would stop responding to ping?
I've read that there are issues with this phone/OS *originating* ping - that is NOT the case here. The 'ping' command is never used on the phone. The phone is receiving pings.
Pings are not entirely blocked since it responds correctly for the first few seconds (though not quickly - usually well over 40ms).
This feels - wild guess, could be way off base - more like the GS4 has determined that these pings are some kind of attack and therefore decided to stop responding. Is there anything like that in there? I don't know who would know the internals.
We have not seen the issue with GS3 4.3. We don't currently have any other devices running 4.3, though there is one Galaxy Nexus which could be upgraded.
* Why? Two reasons.
1. The Realtek function which we can call on our computer to determine whether there are any wifi clients connected quite frequently returns false data, and Realtek won't help us. Thus ping is now our method of detecting when the user has walked away.
2. Some older phones (not GS4) are quite sluggish in the ensuing file transfers from our mobile app unless 'prodded' in this manner. We haven't figured out why. It's like they need to be kept awake at a sub-second level.
Some cases were nothing complicated - the phone was deciding that the quality of the wi-fi connection stank so it was switching back to 3g. Turning off Auto Network Switch in the phone's Wi-Fi / Advanced settings fixed that. Other cases continue to show the problem even with that switch disabled.
My Nexus 4 isn't connecting to wifi. More specifically, if I am connected to a remembered network, my phone does not automatically reconnect when I leave the range then come back into it.
Now, there are 2 wifi networks in the apartment and I've tried both. I actually just "forgot network" on the last remembered network on my phone because I was trying to connect to the better one.
Since I've done that, I am unable to connect to wifi at all, because the only way for me to connect to wifi before was to restart my phone and have it automatically connect to the remembered network.
Now that I don't have a remembered network, I cannot connect to anything, and my Wifi page on my phone will not show any wifi networks available and it won't even give the option to turn on wifi or to refresh the list. I have to reboot my phone, making sure the wifi is off first (using the toggle on the dropdown notification menu), then I can at least refresh the empty list. When I refresh the list, it gives me an error, "WPA failed. Retry in a few minutes."
I need this fixed. I live in a basement apartment and my cell signal is usually unavailable while I'm home.
I was running the AOKP 4.3 milestone when I started having the problem, then went back to stock, put on a 4.4 nightly ROM, had the same problem, then went back to the same 4.3 milestone. Unfortunately, I didn't leave my phone on stock 4.4 long enough to see if the problem persisted there.
Is there anything I can do at this point before going through the process of bringing my phone back to stock again?
Thanks
Update: After restarting my phone some 20 or more times, I was eventually able to see the list of networks and put the password in for the new network. So I at least have wifi now because my phone automatically connects.
However, all the problems stated above are still the same. I lose connection and cannot automatically reconnect when I go out and back into range of the signal, and can only regain the connection when I restart my phone and it automatically connects to the one known network on reboot.
If there's any information or anyway to try to fix it, I'd love to know.
Thanks
This started Feb 3rd or 4th. The phone will connect to the wifi network, with a good signal. It will then re-scan every 5 seconds or so. This is causing all sorts of data transfer issues from downloads freezing to apps losing connectivity while running.
I am running on Verizon.

I am now running Android 5.0 but had NOT updated to 5.0 when this problem started.
I scoured google a bit and found an ATT forum that is essentially reporting what I am.
forums.att.com/t5/Samsung-Discussion-Support/Samsung-Galaxy-S5-Wi-Fi-Connectivity-Problems-After-4-4-4-Update/td-p/4190704
All other devices on the network are operating without issue - phones and computers - as was mine until now.
I have power cycled everything.
I have checked the routers settings.
The phone has been power cycled several times.
The phone has had every wifi setting that would be causing this scanning, that I know, disabled.
The following are off in Wifi > Advanced:
Wifi notifications
Passpoint
Always allow scanning
Smart network switch
I then, after the above, updated to Android 5.0. The issue still persists. Help me please.
My device does this, too. Cant say I have ever really noticed, I dont know if it has always done this or not.
I am not experiencing any issues like you describe.
Now that I think about it, I think it will always scan at a set interval when you enter the Wifi settings. It assumes you are looking for a network to connect to. I doubt its scanning when you are not in that setting.
I had this problem the other day. I went to wifi settings and had it forget the network and then rebooted and reconnected to my wifi network and it seems to have resolved the issue. others have just switched airplane mode on and off and this fixed it. good luck
