I have an SGH-I337 that is running Cyanogenmod 11-20151112-SNAPSHOT-M12-jflte with baseband I337UCUAMDB, and I am experiencing some odd WiFi behavior.
The WiFi will be connected, showing in both the notification bar and the WiFi settings, the notification bar with show traffic (blinking up and down arrows), and yet apps won't be able to access the network. I can restart the WiFi via settings and this will usually restore app connectivity, though not permanently; eventually apps will lose connectivity again. Rinse; repeat.
At times I'll get annoyed at having the WiFi problems and turn WiFi off and use LTE. However, the WiFi eventually turns itself back on, often times exhibiting the connectivity issue that drove me to switch to LTE.
Another issue is that the WiFi will forget the settings for a given network. The WiFi app will simply show the network, not indicating that settings are saved, and I'll have to enter them again.
I haven't been able to establish a pattern to these issues, and it's driving me mad! Has anyone seen anything like this? Have any suggestions, besides taking a handgun to the phone?

Ran into some weird issues this weekend with my wifi connection with my focus.
The phone would randomly disconnect from my home network (strong signal, secured) and connect to an open network with weak signal. I would find this out as I would try to do something that required data and it would just hang and do nothing, I would have to go into settings and disconnect from the open network, reconnect to mine.
Frustrating that there was no way to force it to use our home network or to forget the other network and it stay forgotten.
Anyone had any similar issues. It was just this one day it did it, but was incredibly frustrating. I'm still within my 30 days, so if this is going to be an ongoing issue, I might should reurn the thing for something else.
I'm running Cyanogen 7.2 stable on my Droid 2
It seems I cannot successfully transition from wifi to 3g, or from 3G to wifi without hard resetting my phone. If I turn wifi on, then hard reset the phone, it will connect to my chosen access point, I'll get an IP address, and be able to use internet. But when I go into wifi settings and disable the WiFi, it will claim to connect the 3G but I will not be able to connect to any internet site. The notification area will show 3G icon in white, but never turn cyan to indicate a successful data connection. Trying to turn on airline mode does nothing, and the phone will not go into airline mode until I also, turn it off and turn it back off. Then it will reboot into airline mode. A simple soft reset doesn't seem to solve this problem, I have to preform a power off, and then turn it back on.
Conversely if I set it to use 3G and hard reset it will successfully connect to 3g and work fine, but turning on wifi will result in a connection to the access point but no actual data tansfer. Just as before it will show the connection option's icon on the notification bar will show the WiFi icon but it will say white, and never successfully connect. Alternately wifi will connect and the drop the connection repeatedly.
I've looked all over here, and Google for any working solution but I haven't seen any. Mostly just people having trouble connecting to a specific router, which I DO NOT have. Specially the hand-off to 3G and back seems broken and I have to do a hard reset 100% of the time to change from wifi to 3G and back.
Could somebody point me in the right direction for a solution that hopefully won't involve wiping my phone?
Just popped open my S4 yesterday, and it has been fantastic. I've just been wondering if anyone else has been experiencing a problem with the smart wifi feature. Whenever you leave it on, if a Wifi Signal is a dynamic IP it seems to drop it if you move around within the area and is unable to connect with other routers hosting the same connection, however, when it switches to the data, either 3g or 4g, I am unable to resume data connections over the network, even after waiting a few minutes, and sometimes have had to restart it. Any others having this problem? Or am I just impatient.
Hi,
I have the strangest behavior with my wifi, the phone keeps connecting and disconnecting between 4G and WiFi every few seconds when i'm at home. This drains my battery in couple of hours and I can't do anything unless i turn off WiFi. I have smooth transition between 4G and Wifi enabled in settings (i've tried disabling it, all it did was to speed up connect and disconnect between 4G and wifi) Anyone else experiencing this strange behaviour with WiFi and 4g?
I have the same behavior. You need to disable "Smart network switch" under the advanced Wi-Fi settings. I have not found a fix that will allow leaving this feature enabled.
I disabled the "smart network switch" and my phone still refuses to connect to known networks that are well within signal range. It may be staying connected better once connected but I have my wifi sleep with the screen so when I wake it up, the wifi should re-connect. Not working well at all. This 5.0 update sucks, you'd think that since Verizon takes forever to get updates to flagship phones that at least they'd be well tested and stable, NOT!
I know i'm not alone since i've seen this issue not only on my phone. When i'm at home my phone is mostly connected to wifi. My router is Linksys AC1900. Sometimes both the wifi and 4G icons appear together. when this happens my battery is draining like hell. a simple restart of the phone or the router is not a solution - i found that in order to make the 4G icon go away i need to first turn off the router so the phone is connected only to the mobile network, than i have to turn off both the data connection and wifi of the phone; than i need to go and clean the cache through the builtin recovery menu. the problem is that sometimes even performing all these things is not enough and the 4G icon won't go away. Download booster and Smart network switch are both turned off, but playing with them do not really affect the issue. also i tried connecting to both 2.4 or 5ghz wifi with no difference. i also tried setting a fixed IP address for my phone, but again this does not affect the issue. any ideas? i'm pretty certain that it's not a hardware issue since i've seen it happening to other people too. it's quite annoying since it's totally destroying the battery life of the phone and it seems that there's no real solution for this behavior.
What model number is your phone? Have you considered reflashing firmware / factory resetting the phone?
The model is 935f. I've tried reflashing with stock several times (the phone is not rooted) but after a while the problem comes back. This is the only issue I've had with this phone but it's quite annoying.
I've got the same issue. The only solution i've seen till now is to reflash with a custom rom.
Same
I have picked up the same type of issue. I did some snooping around and have found that if I have my mobile data on when in the streets and when I get home and I turn on my wifi, that if my wifi signal is very bad and my mobile data is on, then it would show both signals. It's as if the phone tries to get whatever data from both, since the wifi is so bad. I agree that it really chows the battery. The only fix I could get to work is to switch of the data and move closer to the wifi where it's the strongest. I will sit at the router for a minute or two, It then automatically removes the 4g sign and only works on wifi. If I stay where the wifi signal is bad and disable mobile, it stays there even though my data is off.
Did you do a factory reset and restore your phone to its original settings?
