I haven't been able to get anywhere with this issue I've been having for a few weeks, so I figured I'd fire up my old xda account and see if anyone on here can help since this is a more techy crowd. I've searched and searched but I haven't found anything similar unfortunately.
Tl;dr I have to log in to my work's guest wifi every day, but I didn't before. Nobody else does. Auto connect is set to on, but it doesn't work like it used to/is supposed to.
Longer: I connect to a guest network at work every day that's meant for employee personal devices. (I use a homebrew VPN for this.) Before the issue started, I'd periodically (maybe once/month if that) have a notification when I arrived to sign in, and you click agree in a captive portal and you're on your way. Other than that it auto connects just like at home. A few weeks (?) ago however, I've started having to do this every day. If I'm disconnected for over roughly an hour (say if I leave and come back during the day) I have to do it again, and if I reboot my device I also have to sign in again. If I just toggle wifi on and off quickly then it automatically connects just fine.
Ordinarily this wouldn't be a huge deal, but where I work I basically get no cell coverage. I also have a couple tasker profiles that I've been using for years to do stuff (vibrate mode, silence media, etc) when I arrive to work, and these don't/won't trigger until I have a minute to log in. Ideally these would trigger as soon as I'm within range of the building, as I've been doing for years now.
None of my coworkers have this issue, everyone that I've asked all say their devices automatically connect just fine, as mine used to.
I'm assuming this is something related to my device. Because it happens if I reboot, but not if I quickly disconnect and reconnect, I'm imagining maybe something isn't being cached correctly?
If anyone can help me fix this I'd be very grateful!
Solved: dev setting for non-persistent Mac address randomization was on.

I've read on this for several days now, I've searched the forums and I just can't find an answer so here's my thread.
I've recently bought a G1 it's running JF_Holiday and I'm on AT&T with no dataplan. I have WiFi at home and at work and it's getting e-mails while I'm around the office that I care most about.
What I've found on the forums talks about Wifi shutting off while the phone is asleep. I have that solved with Wifi Lock. However, I juts can't get the phone to stay on a wifi network for an extended period of time. Both at work and at home if the phone is left for 30 minutes asleep in a strong signal location it disconnects from the wifi. The wifi will reconnect if shut off and turned back on.
Is there a solution to this anywhere? Just an app that I could turn on that would automatically reconnect to wifi indefinately would be nice. When I'm at work or home I'm not that worried about battery life I can charge it at any time. I am however, dissapointed that walking around work it can't stay connected to my e-mail. If I have to unlock it, disconnect/reconnect, and then wait to see if I have any e-mail I might as well walk back to my computer and look.
Also, I have Locale turned off, Battery Monitor turned off, and I can't think of any other app that could be messing with wifi. Can anyone help me here?
Edit: A few times it does manage to stay on for 1hr+ sitting at my desk. I guess it's possible that the problem is when there is a brief drop out in the signal it just doens't reconnect (or doesn't try enough times). Is there anything to address that? I was sure someone would have a way to aut-connect to a network indefinitely but I can't find that anywhere.
Wifi Disconnect
I might have found part of the problem. We use repeaters and a single SSID to cover a large area at work. I think there might be an issue with the G1 locking onto an accesspoint based on MAC address and not freely jumping between them. I've added one of the routers from the 2nd building as an accesspoint we'll see if that helps.
If that's the case can anyone help:
1 - Set it to swap access points based on signal strength
2 - Add all the access points, currently I try to find a spot that's out of range of the one I'm connected too and add a new network. It associates that network with the new AP and my signal strength goes up.
It might be that I just need a way to add multiple access points to the setup and then it will swap automatically, but it's hard to say b/c I honestly don't know where each AP is
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.
Alright, this is a frustrating issue that I've been having since day 1 with WhatsApp, and it's not even just SGS4, but with my old SGS too.
Problem:
Phone screen turns off while on WIFI, after a while of inactivity, WIFI still seems to run, but WhatsApp lost connection and takes a long time to reconnect, and usually requires a full restart of WIFI.
This does not happen on 3G for me, it only happens when WIFI is active.
Things tried:
- Turn off 3G entirely, so it only runs on WIFI.
- Reinstall WA
- Restart phone.
- Do a clean install of firmware (on my old SGS).
- Test it out on new phone~ (Brand new SGS4 i9505)
I don't know what's causing this, can anyone please help me figure this out? Let me know if you need more info.
is your router set to "always connected" or does it disconnect after sometime if no data comes in?
maybe i'm wrong but if it's only a wifi problem you maybe should look into your router settings.

Already looked into that.
Weird part is that Skype stays connected perfectly fine, but WhatsApp never does.
Please search a bit, this has been answered just a day ago.

[Q] WhatsApp Issues on GS4
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.
Hi all, as noted in subject, occasionally I am connected to WiFi but I get no active connection (nothing comes in or goes out). The only way I remedy this is disabling/enabling WiFi and as this is a small annoyance, any reason this happens? I have an RT-66U router as well, if it matters.
Thanks and happy holidays.
Nobody?
Hi
could you solve it already?
if not, switch location settings to GPS ONLY.
good luck

Yeah I'm having the same problem except even when disabling/enabling wifi, I can't get a reliable active connection. It's only when I turn on airplane mode and off and reconnect. Then will I get a reliable internet connection. I'm not sure what's going on. The strangest thing is this problem occurred over time. First month, no problem. 2nd months, occasionally. now, into the 3rd, it's on a daily basis. My previous Verizon Note 2 also had this issue but then seemingly disappeared, only to rear it's ugly head a few months down the road.
Here's a post on reddit with others having the same issue: http://www.reddit.com/r/galaxynote4/comments/2ks0ap/note_4_wifi_issue/
Not sure if a custom rom would solve it. For now I'm just using my 4G connection as I have the unlimited plan.
turn smart switch off and see if it helps. does it get an ip address ?
Have you rebooted the router? Unplug it, wait a few seconds, then plug it in again. My router does this every now and then.
Also try rebooting your phone.
If neither one of those work, then you can try factory resetting your phone as a last resort. After that, if it's still not working then either your phone or router is busted.
