Hi guys, I've already solved this issue but couldn't find any info on it while it was going on, so wanted to share what happened and how to fix it, just in case someone else runs into this. I think this is the most appropriate section to post, but if not, please feel free to move it, mods.
The problem was this: WiFi suddenly stopped working on my rom. It just straight up wouldn't turn on. Pressing the wireless icon in the launcher did nothing, and from the settings menu I'd see the "to see available networks, turn Wi-Fi on" message, even if I turned it on. Coming out of that screen and going back in would show the WiFi was still turned off. Reboots didn't work, uninstalling suspect apps didn't work. I was ready to wipe & reinstall the rom.
The solution is this: I then had what I thought was a really dumb idea. Try changing the WiFi frequency band. It worked. I'll explain what I did step by step;
Long press the WiFi button in your notifications bar, or go to Settings>WiFi
Press the menu button (either the menu key on your phone, or the three dots at the top left of the screen) and select 'Advanced'
Tap on 'Wi-Fi frequency band', and change it from automatic to '5 GHz only' (it may be your WiFi is on the 2.4 Ghz band. I'll come to that)
Reboot your phone
If your WiFi is on the 5GHz band, and your issue was the same as mine, it will now connect to the network and you'll have internet (you may need to turn WiFi on, first)
If it didn't, repeat the steps above, but this time choose '2.4GHz only' instead of 5.
Hopefully you'll now be online again. If you like, you can now change the frequency band setting to automatic again, and the WiFi should work just like it was before.
I really hope this can help some folks who might experience this in the future. It was such a weird issue, and it's such a simple yet obscure fix. With any luck this'll prevent any unneeded wipes.
Had a similar issue on another device... this might help with that too.

Hi
I have an HTC Desire HD
I have changed a setting somewhere (i remember doing it) which switches off wifi when the screen times out. I did it on purpose at the time thinking it would come on again when the screen was unlocked. Wrong!
The problem is I now can't find or remember the exact setting I changed!
Could be powersaving, wifi, screen lock or any other non-obvious setting!
I have tried everything I can think off. At the moment, everytime the screen goes off, so does wifi. Very annoying
I would really appreciate any help

I wasn't aware there was an option for this is froyo! Unless you're referring to the WiFi sleep policy? Try menu > advanced when in WiFi settings but I think this only allows you to determine the time out period, not the condition (ie the screen going off)... however, there are apps that will allow you to do this. Are you sure you haven't installed something that's causing this?
Go to wifi and press menu. Its under advanced settings.
Hi
Thanks for your tips. Found it!!
It wasn't in the Wifi, or screenlock settings (I had looked at everything on those!!)
I remembered that had installed the Battery Booster app and then messed with the Battery Teak settings to turn off wifi on screenlock
Actually a handy app, if you set it up properly, which I hadn't!!
Thanks once again for the prompt
Mark
don't forget after change setting hit menu button again to save the change lol
Guys,
I updated my tab a few days ago. Now the market looks different but unfortunately I'm facing another irritating problem which I have no clue how to solve.
Every time that I turn off the tab, and let it be idle for 10 minutes, when I turn it back on, the WiFi icon will show no bars - which translates into no internet connectivity. That happens while the WiFi button is still pressed (green in the pop-up menu). In order for the device to connect to the net I need to turn the WiFi OFF and than ON and it works.
I checked the WiFi sleep configuration and they are set to "never turn it off" I also rebooted the device but with no change.
Please let me know what to do... as this thing sometimes just drives me crazy.
Thanks.

Flash a custom rom bro. Otherwise you are stuck with Samsung's awesome bugs. If you don't want to flash a custom rom there isn't really much you can do about it considering you're not rooted. What did you update to? KMP???
I did the regular Samsung update -the latest one that was released a couple of says ago. The problem with rooting is losing the coverage I have for insuring the device... which I'm reluctant to do. I'm sure it has a solution somewhere...
Yes I confirm.
This "reconnect" issue is being discussed on many forums with no solutions yet. (except custom ROM)
Hi,
I have some problems with finding my location, and I think it started since the 4.3 update, but I'm not sure.
I see it mostly with Tasker. I have some profiles for different locations (like home and college..) triggered by "net" without GPS, that is ment to turn Wifi on and off.
I noticed today when I left college, I opened the screen on the way home and I saw for a brief moment that the WiFi is still ON and my "college" profile was still activated, and immediately after that, the profile went off and also the WiFi. The Net location only triggered when I opened the screen, and it seems it thought my location was still in college until I did so.
When I got home, I opened the screen to see if it activated my "home" profile and turned on the WiFi, and nope, nada, even when opened the screen it still didn't know my location, only after I turned on the WiFi manually it knew where I am and activated the "home" profile (which in that case was already pointless)..
My guess is that on the way back from college it found my location when I opened the screen cause the WiFi was still on, and when I came back home the WiFi was off so it didn't find my location without it.
But if that's the case, then there is simply no point in those "wifi on / off" profiles if it can only find my location with WiFi.
I posted a similar thread on Tasker support group, but honestly I think it's a problem with the google's new location services.
What's that point? now we can get a good location fix only with WiFi or GPS?
and also why I must turn on the screen to "refresh" the location? isn't "net location" works on the 3g network? which is always on, so what's the problem.
By the way these network delays doesn't only happen with location, it happens alot with messaging apps, that sometimes I get the messages only when I turn on the screen. Is there a fix for that?
Sorry for throwing out so many questions without order
Thanks in advanced
same issue
Yah, I'm experiancing the same issues.
Hi,
My H990DS has been bothering me for a couple of days as WiFi turns itself on without any kind of intervention.
Turning it off manually or having the phone restart does not help. I made sure the latest apps installed make no impact.
Playing with Developer Options made no difference.
I am ready to Factory Data reset.
Anyone experienced something similar ?
Thanks,
My 918 always shows wifi active in GSAM's graph, even when set to "Never" under the "Wifi on while inactive" option in system settings. I ended up just downloading Leandroid from the play store and setting it to disable the wifi radio, and renable it periodically to check for push messages. Seems to work fine with doze and standby time has improved.
Under settings, location, three dots top right, scanning, turn wifi scanning off. It turns back on anytime you use wifi and you manually have to turn it back off each time.
Mine (918) does this all the time. Im thinking its a 7.0 thing. There has been a few exceptions where it has stayed off. In my case I drive through a busy section in town and it constantly connects to the 20 or so open wifi spots so I turn it off. Well once I pull into the garage at home its magically back on.
Maybe something to do with networks it recognizes, Xfinity wifi wreaks havoc on it as well.
As soon as I uninstalled the latest apps, the issue disappeared. Not a single exception in 24 hours.
I suspect a Sip Client had caused the problem.

What!?
That sounds utterly horific for the battery, nevermind privacy concerns. I thankfully haven't experienced anything similar myself, but I've only ever used custom ROMs so perhaps that's the cause. But that sounds terrible.
All day today I have been having Wi-Fi connectivity issues. None of the other devices in my home are experiencing this. It is just my OnePlus 8 Pro that keeps dropping Wi-Fi and refuses to load games. While I'm on Facebook or any other app it refuses to load. It doesn't matter what frequency I am on or what channel I am on. It is not my service provider I have already called and asked. I think something is messed up. So is anyone else having Wi-Fi problems on the OnePlus 8 Pro?
Do you have a private DNS active?
Same here

Mine will only stay connected for short periods. If I put it down and leave it for a while 9 times out of 10 it's swapped me back to mobile data. I've reached out to OnePlus to see if it's a fault or a known problem they're working on.
This is actually happening to me as well. 10.5.8 stock rooted. I see that exclamation point next to the wifi signal sometimes and nothing else in the house is having issues.
Okay so this is what you have to do to fix the problem. Click onto your Wi-Fi and let it go into the settings then swipe up on your screen and go into the app info. Clear your cache. Turn your Wi-Fi off and back on and it should work just fine
I have a much better fix. Change your MAC privacy setting to "Use device MAC" and change from default "Use randomized MAC". Wa la I haven't had a drop all day. This has been driving me crazy!
It might actually be a really simple problem with a simple solution, just i need to see a screenshot with the diagnostics, or the troubleshoot from the device why doesn't it want to keep the connection steady. You can actually learn all these things related to the wifi and some little programming things really easily, it is not that tough, trust me. I took the cisco programming course from SPOTOclub.com, during this pandemic, and in one month i was already an expert in the wireless connection and the LAN and so on and so forth.
If you're having Wi-Fi connection problems or see an Wi-Fi icon with an exclamation point Wi-Fi problem, try the solutions below:
Make sure Wi-Fi is on. Then turn it off and on again to reconnect.
Make sure Airplane mode is off. Then turn it on and off again to reconnect.
Press your phone's power button for a few seconds. Then, on your screen, tap Restart Restart.If you don't see "Restart," press and hold the power button for about 30 seconds, until your phone restarts.
