I'm currently running Phoenix 4.1 and noticed that even with wifi connected, it shows that it's scanning for new networks every few seconds. Is there a way to stop the constant scanning for wifi networks even when it is currently connected? I don't really want to have to set it to disable wireless on sleep since my work connection requires you to accept the t.o.s. every time you connect.
Not that I've found and I've looked too. A "feature" of the wifi so if you're moving around it will connect to open networks.

My wifi seems to disconnect from my wifi when the screen turns off, despite me having changed my settings to never sleep. When I look at the wifi settings it says "Unsuccessful Connection". I didn't have this problem with my MT3G.
Anyone having similiar issues or a fix?
wifi Reconnection issues
I'm having the same problems with mine.
It initially connects to wifi fine but when the screen goes off it sometimes drops the connection and will not reconnect without a reboot.
I have tried setting it to keep the wifi when sleeping but it makes no difference.
I found a few similar reports elsewhere and followed most of the suggestions, like changing routers, changing wifi channels, setting an IP address instead of DHCP etc. Nothing seems to make any difference so far.
Mine never seems to reconnect after waking up, but I just go into the Wireless settings/Wifi settings window (where it lists all the Wifi networks in the area) and press on the network name and it brings up a dialog allowing me to connect again. I press the Connect button and it instantly reconnects. No reboot required...
Try increase your router's "Group Key Update Interval". I had the same problem with my D-Link DIR-655. I changed mine to 10 hours and it's working fine for me now.
i have the issus that my wifi is "connected" i mean i see the logo at the top bar but after a few minutes i don't get any update from the internet like gmail oder twitter when is wake up the device from sleep i get them back again
maybe it something with the Group Key Intervall but i can't switch it on my speedport w700v router
I just tried switching mine, highest it can go is 7200 seconds, so I bumped it to two hours instead of one. linksys
my wifi reconnects when I wake the screen almost 100% but it's not reliable.
I have to go to wifi list and reconnect. Sometimes I disable wifi and then re enable, conects no problem. Irritating
i heared that switching the encryption from wpa/wpa2 to only wpa2 will solve this issues, will try it when i am at home
...seems like almost everybody got this problem.
for example with my Hero i don't had this problems so it's something with the W-Lan card of the Nexus
Got this problem too but will try the suggested work arounds when I get home tonight
found out that my encryption is wpa2 not wpa/wpa2 ... damn so thats not the reason
and my router cant configure the group key intervall
I don't have this issue, running CM5.0.3.1, mine is set to Never Sleep and it does not. My connection does not time out either. I connect to two Trendnet TEW-637AP's at home, in mixed b/g/n mode with WPA2-PSK mode security.
Could it be, that this prob exists just for nonrooted phones?!
i've got mcr 1.6 which is rooted and don't work
i think it's a problem with the wifi card and the wifi router
rooting just means that you get read/write access to all folders
doesn't change anything on your wifi connection

Not exactly, it means also modified system files, which could include those that interface with the wifi chip and those that control the sleep state of the device.
Also, Cyanogen (and most other custom roms now) are running on a different (newer) kernel.
yes i know
but mcr is although running on different kernel and it's not working there
i don't think its an issue bei the stock rom and mcr
maybe here is someone with CM where the wifi drops?
edit:
okay i tried it with the desire rom version from modaco, the same failures, maybe i try a CM built now, and see if it changes
Code:
[B]Rom [/B] [B]Router / Access Point[/B]
MCR 1.6 | Speedport w700v | not working
Desire MCR | Speedport w700v | not working
CM 5.0.3.1 | Speedport w700v | not working
i think this means it's not a rom issue, its something with the routers and access points in combination of the wifi card from the nexus
That´s strange..perhaps just accidentally, but: yesterday I installed "Task Manager" , which has an auto-kill function.....since then my Wifi reconnects perfectly
maybe because it automatically does anything inside of the 10 minutes which keeps the wifi active?
which one did you install?
there are a lot of them on the market
which developer?
edit:
ah i found a strange issue, today i was at the wifi of my girlfriend, she has the same router BUT i don't have the wifi problems there, with the same model of router thats very strange
i found another work around, i set my twitter client to 5 minutes update intervall, this means every 5 minutes is network traffic and the connection won't drop after my 10 minutes public key intervall change
don't know how much battery is used while setting from 10 to 5 minutes but i think it should be okay
Try a different WiFi channel
I've seen reports of WiFi connection problems being solved by changing channels on the AP. Channel 10 seems to be a consistently reliable choice.
All of the WiFi issues I have found seem so to be that the WiFi cant connect properly.
I have the opposite problem in that I am not often near free networks. When I leave my house, I turn the WiFi off on my phone.
So I will be watching something on youtube or updating mail at work and everything will just quit. I check the connection and the WiFi is back on and everything stopped because it is trying to connect to WiFi and not staying on my Sprint data connection.
How do I make it quit? I will be at work where there is a highly secured WiFi connection used by some of the more remote robotic systems. My phone will suddenly pop up and tell me that a WiFi signal has been detected and I will get better service by using that connection.
I only want to use WiFi when I turn it on - not when the phone suddenly decides to turn it on.
Thanks
Roxann
If you're on Sprint then you have an S4 and are in the wrong forum. This forum is for the S4 Active.
Running any Marshmallow rom on this phone always turns the wifi off after about 30 seconds of screen-off time. This is incredibly frustrating because it breaks any app I have running in the background that uses wifi. For example netflix on chromecast always loses it's connection and I cant control my chromecast because the wifi disconnected. It's also needlessly using cellular data while asleep.
I have checked all the wifi options and theyre all set correctly. There is a whole 10 pages of complaints about this on a simple google search with no real solution provided. You guys have any ideas?
Hi community,
I'm writing because I have a strange WiFi problem with my S21 Ultra which I had with no other equipment before.
Setup:
- Galaxy S21 Ultra
- FritzBox 7590
- Fritz WLan Repeater 1750E (2x for better range coverage)
- WiFi 5G Auto channel WPA2/3
- WiFi coverage is good (tested with a lot of other devices)
Phone Setup:
- Paired with the WiFi
- Do Not use Mobile Data
- automatically reconnect to wifi
Problem:
The phone does not automatically connect to the WiFi.
The phone also looses the connection to the WiFi several times a day.
When the phone is not connected to the wifi I open wifi settings.
- It happens that the wifi list is completely empty and the circle animation indicates that the phone is searching for nearby connections
- It happens that the wifi list contains a list of wifi networks the phone has seen before when it was connected last to a wifi
- Switching off an on the wifi helps to find the actual networks and the phone then connects back to wifi (most of the time)
I tried already several settings and combinations but so far none of them brought any success. So I would like to know if someone else had a similar issue or has an idea what could go on here.
To me it seems strange that the wifi scan is not working as I would expect it. I would expect the phone to continously refresh the wifi list with networks it sees, but always when the phone lost its wifi connection the list is not working anymore.
Try tinkering with the wifi channels and encryption until it shows up.
Or you can try resetting the routers to see if it does anything
This person has a similar issue

Has anyone else have WIFI connection problems ? With not finding any WIFI until i factory reset it? And after a few days the problem reappears. Last time i didn't factory reset it and after 3 days, with no adjustment, the phone found WIFI, but...

You said the phone loses connection and etc. Does that happen only at the location you described, or does it also happen at other locations?
It is possible that your phone also gets confused with the router and the repeater.
1st you need to clearly understand if the issue comes from the phone or possibly from your WIFI devices. Once this is clear, you have something to go on with...

- Phone is on standby (placed on a table, etc.)
- I turn it on to check messages,
- No connection to wifi
- Open wifi manager
- No wifi networks listed at all
I do not know why my router/network should be the problem. All other devices in the wifi work flawlessly. It cannot be that I have to restart my wifi router every time the phone finds no wifi at all. That makes no sense to me.
It looks more like the android wifi service is still on sleep and does not report new wifi networks (which would be necessary also to see any wifi at all).
May I suggest....
Settings -> Connections -> Wi-Fi -> (three dots it top right) ->Advanced
Make sure "Turn on Wi-Fi automatically" and "Wi-Fi power saving mode" are both off.
If you use a repeater is it a mesh or AP solution? I find Android will drag its feet letting go of a wifi signal even when walking into range of another known network. Had an extender in garden and even when down to 10% connection on Wi-Fi it would stay connected to extender, I had to turn wifi off and on quickly to get it to pick a better network.

It seems to be the phone...
Definitely try what lywyn suggested...
you can also submit an error report on Samsung Members app, it sends reports directly to Samsung and get the feedback.
Download the app from the Galaxy Store if you don't have it on your phone > Memers app > + button > Error report

Unfortunately no success. I configured exactly like suggested. Does the S21 Ultra have problems with handover in meshed WiFi setups?

Never had any problem with my S21U (Exynos) with my Mesh WiFi (Deco X60) setup.

sometimes it happen when you connect at certain locations.
If you haven't already done so give this a try. Settings, search "Wi-Fi", scroll down to Location, Improve accuracy - toggle on, Wi-Fi scanning - toggle on.

Mesh is a single network solution so should not be a problem.
The only other thing I can think of is the power-saving mode. My son has his Pixel on power saving all the time and I know sometimes he has to turn off/on wifi to get a connection when waking the phone up
I found the issue! It is WiFi Direct related. The app "nexar" from the dashcam is interfering with normal WiFi on this phone. Nexar conquers the WiFi functionality and is responsible for my wifi disconnecting. The app requires the "Location always" permission. If I remove this permission my WiFi works again normally. So: one has a similar issue: remove "Location always" permission from the nexar app. In my case it helped.
You said the phone loses connection and and many others. Does that show up best on the region you described, or does it also happen at different places?
Kodi nox
It is feasible that your phone additionally receives harassed with the router and the repeater.
1st you need to honestly recognize if the issue comes from the cellphone or likely from your WIFI devices. Once this is clean, you've got something to go on with...
I would like to create a task on Android 12 to run the "fix connectivity" under internet. I would like it to check my cellular connectivity first and if not connected run the fix connectivity. Is this possible. I would at least like to run it when disconnecting from wifi. Since my phone updated I have been having problems with my cellular connection going to not connected, while still having bars, after being on wifi for a period of time. It does not connect back when disconnecting from wifi. When this happens I can't receive certain texts and can only wifi call.
