Bell JK4 - Wi-Fi Discussion

After upgrading to JK4 via Kies I've noticed some strange Wi-Fi behaviour. It seems to manifest at different times and for no apparent reason, so I'm starting a thread to see if a) anyone else has this issue and b) if so, how does it manifest for them.
First manifestation: after turning on Wi-Fi through Notifications the text switched to "On" but the Wi-Fi symbol did not turn green. Going into the Wireless and Network settings on the phone caused a temporary lockup, when it did let me in Wi-Fi was showing "Error". A reboot of the phone fixed it, temporarily.
Second manifestation: after turning on Wi-Fi through Notifications the text switched to "On" and the Wi-Fi symbol turned green, but it did not connect to my wireless network automatically like it should. Going into the Wireless and Network settings on the phone caused a temporary lockup, when it did let me in Wi-Fi was rapidly switching from a "Turning on" state to "Turning off". It did this about 10-15 times in a few seconds then went to "Error". Turning on and off the Wi-Fi again solved this issue.
Every time I solve this it seems to come back within a 24 hour period. I didn't have this problem (from what I can see) on JK3. I factory reset before and after flashing to JK4, and I flashed JH2 back just to be on the safe side beforehand.
Let the discussion begin!

I quickly tried out after reading your post, and I did confirm your first issue happening, but only when I turn my Wi-Fi on and off really quickly. Also my phone didn't lock up as you described either. Basically, I could only make that issue to surface once I turn off the Wi-Fi, and then turn it back on as soon as my phone reports it is disconnected. When I go into Wi-Fi settings, it does say "Error" there, but if I check the "Wi-Fi" there again, it connects automatically.
I almost never use Wi-Fi because I get 6GB of data, but I can see this becoming a very annoying issue if you have to use Wi-Fi frequently.
Edit: Actually, I ran into a different issue just now. I kept on playing around with my Wi-Fi, and confirmed this happening: Wi-Fi text turns to "ON" but the icon doesn't turn green. When I go into settings, it says "Turning Wi-Fi On.." or something similar and is stuck there. I wasn't able to turn on nor off the Wi-Fi. Reboot fixed issue...for now I guess.

I have also had this issue but I believe it has to do with trying to turn on wireless when your preferred network has a very weak signal. When I'm next to my router, I can turn wi-fi on and off rapidly with no issues. I have only had the issue in my room which has a much weaker signal.

i was having problems with my wifi today...i wasnt able to pickup any wifi signals and i couldnt manually turn the wifi on either...i got a few force closes on some apps and decided to reboot the phone, hopefully sovling the problem...instead i got stuck in the boot loop at the i9000m logo and now my internal sd card is done....hopefully i can return this pos at bell(im on rogers) and do a hup through rogers for the iphone4...at least thats a stable device.

I've never tested right beside the router, but my room is next to the room which has the router so I would think I'd have a fairly strong signal.
Interesting, though...

I tested my Wi-Fi pretty much right beside my router as well...like less than 3 feet away. My phone was reporting it was seeing an "excellent" signal.

I find my wifi on my phone to be pretty solid.
I have an occasional issue where it does not see my wifi router at work, but all I do is turn it off / on and off she does. Just happens with the work router. Never had an issue with my linksys at home.

I've experience this issue with JH2 and it was caused by a change to fast in the settings. Just give your phone some time to connect and get identified on the network before you turn it off ans don't torn it on right after you disconnect it and you should be fine.

Been having the same issues since upgrading to JK4. Wifi gets stuck in "enabling" state occasionally when it try to turn it on. Sometimes I have to go as far as restarting the phone to get it to work again. Not a huge deal but still a nuisance.

I have seen both of these situations occur once after applying JK3 from Odin. It was shortly after booting it up for the first time including the "ERROR" text. I attributed it to a one-time glitch and it has not come back since. When I am home I force WiFi on and leave it in that state until I leave the house for work the following day so I am not constantly messing with the settings.

I get a similar issue butt only when activating my mobile AP.

I've been having a similar issue with my wifi since upgrading to JK4. I've gotten the "error" message on enabling wifi, but as others have mentioned it may be because I'm re-enabling it too quickly after turning it off. However, in one instance yesterday I tried re-enabling it several times after turning it off via the control widget and was ultimately forced to reboot before it worked again. Also, this morning I found that after leaving home and coming to work, I was still only seeing the wifi hotspots near my apartment rather than the ones in my new location (one of which I have saved and automatically connect to). I had to reset the wifi to find the local hotspots. Other than these wifi issues, I'm really loving JK4 so I just hope they get sorted out.

Odd Behavior on Boot

I have a stock unrooted Verizon Galaxy S5. For several months my phone has been plagued by several issues at startup. Whether I reboot the phone or start it up after the battery has died, it always enters an odd state immediately after loading and seems to get stuck in this state for an undetermined and variable amount of time (anywhere from a few seconds or minutes to hours or even overnight).
While in this state, this is what happens:
1. Screen stays on. Once I unlock the phone, the screen stays on. The side button doesn't do anything to lock the phone or turn off the screen. Holding down the button, however, still triggers the power menu. The screen timeout never triggers, even though it should turn off the screen after 2 minutes of inactivity.
2. WiFi and Bluetooth turned off. Even if they were turned on before I powered down the phone, they are not enabled when the phone first boots up. I can manually turn them on but the WiFi will not connect to a network, even if one is available. It may show it is connecting to the network, but it gets stuck at "Checking the quality of your internet connection" and continues to use the 4G network for data connectivity. This happens no matter what WiFi network I am within range of, so it's not an issue with the network or router itself. If I am not near a network at all I will still experience the other problems of not being able to lock the phone, etc.
3. Startup applications don't load. I have Tasker on my phone, but it doesn't load and show it's notification bar icon.
Otherwise, I can use the phone normally and open applications, surf the web, etc. It seems that loading some applications and using the phone eventually causes the phone to exit this mode, but I haven't been able to find a single particular application or series of steps to fix the problem. If I power on the phone and don't use it that just seems to make it take even longer to fix itself.
Once it gets out of it's weird state, the WiFi connection will become active (it will turn on WiFi if I haven't done so manually already) and it will connect to a known network if one is available, the phone will lock itself or I can do so from the side button, and things like Tasker and Power Save mode will turn on.
I am stumped as to what could be causing this problem or how to fix it. It seems the phone may be doing some kind of check, maybe related to Knox, that hangs during startup and prevents certain things from working until it straightens itself out.
Any clues into what this problem is, what is causing it or how I could further analyze this problem and determine its cause would be greatly appreciated.

Never heard of or experienced these issues. May want to contact Samsung.

Have you installed any official updates from Verizon at any point? I've heard of phones having phantom problems like this after receiving a bad update. I would definitely contact Verizon if you did update at any point. If not then like BigBot96 said, contact Samsung about the problem.

My wife's Note 2 did something similar when the battery died. I had to factory reset. Her phone was rooted/unlocked & running a custom TW ROM, though. May I suggest doing a complete factory reset and Odin. Backup data to computer or external sdcard since this will clear the entire device.
Edit: After rereading OP's post it actually sounds like an app is hanging at startup which could cause this behavior. A logcat should tell you what's going on.

Wi-fi is bricked

Ok, so my phone has this problem where it keeps turning on and off randomly, which I think is now known is an issue with some LG G2's and you know I hate it but I guesss I can live with it. Even though if any of you have a solution for that please tell me. But now one time when it turned off and then powered back on, the wifi stopped working. I don't mean my network, I mean the actual wifi on my phone. When I scroll down my notification bar, the wifi logo is grey but it's flashing, like it usually does when you turn it on, but it doesn't turn blue. When I got to the wifi section on my setting, the on and off switch is greyed out (but faintly blue, even though you can't touch it), and when I tap on the wifi section itself, it just says "wifi turning on.." HELP PLEASE

re flash the rom. i have things happened like that before, wiping all and flashing another rom fix, or go back to stock, sometimes the options settings are grey out. that fixes it.

LG G2 Wi-Fi won't turn on

Ok so I recently upgraded from a LG G2 to a G4, because my G2 was bricked. But I was hoping to still use the G2 for music and games so on road trips I don't need to waste battery on my G4. But the wi-fi won't work on my G2.
My G2 had the problem of just randomly restarting, sitting on a table or going on snapchat, you name it. But one day it had a really bad loop. It would turn on, and off, and on, and off for about 10 minutes, and then finally it stopped, but when I went on the phone the wi-fi stopped working. Not just for a router, but it wouldn't turn on. The wi-fi logo on the notification bar keeps flashing but it won't turn on and when I go to settings, it just says "wi-fi turning on.." I've already factory reset it. Can anyone please help!! PLEASE!!

S6 Edge+ SM-G928T WiFi issues

So I have the SM-G928T galaxy s6 edge+. It has a few issues, one being the wireless charging constantly pauses and then comes back and sometimes just stops all together. I fixed this with turning the daydream feature on. My BIGGEST issue is the Wireless! The wireless adapter CONSTANTLY turns itself off at random, then turns back on a few seconds later. This causes any downloads, updates, etc to fail.. I've read that I am not the only one with this issue, but so far no fix has been really found... I've gone into recovery and cleared the cache partition, made sure that smart network switch is turned off, keep wifi on during sleep is set to always (even though it shuts off while ACTIVELY using the phone). I've done a factory reset more than once, each time clearing cache partition. I've been told in several other places that it's my wireless router... This is NOT the case.... For one, I'm a network admin. If it was router issue, I would know it. Secondly, it happens no matter what network I am connected to. Public wifi, home wifi, corporate wifi, etc. All have the same result. The only thing I have not noticed is if it does it even when there is no network traffic on the device, mostly because I don't just sit and stare at my phone when I'm not using it.... Only notice it WHILE I am using it. My assumption though is that it's only happening when the device is USING the wireless connection. It is also important to mention that this is the 2nd device to have this issue. I thought it might be hardware issue so I exchanged it for a new one, and it also has this problem... Maybe I just have terrible luck....
Does ANYONE have any ideas on this?
