Question 'No Wifi/5G Signal Icon' Beta 4 Bug - Samsung Galaxy S21 Ultra

I've been on beta 4 for about 2 days. After a reboot, the status bar has randomly and permanently stopped displaying any of the internet connection icons. It makes it look like there's no internet connection whatsoever.
If this had actually been the case I would have gone right back to AUHD.
However Wi-Fi and my 5G signal work entirely just fine. Anyone else encountering this issue?

Have you tried resetting network settings ?

Q Wifi issues

Greetings,
i have my HTC one for 3 weeks now but the past few days it started acting weird. Whenever i connect to a wifi it works for around a minute then it says no network connection but it is still connected to the network and the indicator shows full signal strength. Happens basically with every Wireless i tested with different encryptions channels etc. It also doesn't use it's mobile connection when wireless is connected that works perfect. First i had Trickdroid 7.5 on it and after 2 days when i was annoyed by that issue i did a full wipe and installed Trickdroid 8.0 but it didn't help. Any idea what that could be?

Did you ever find the answer to your wifi issues?
I'm having very similar problems.. It shows I'm connected, but no data is moving. I have 0-1 bar of cell signal, so I rely on wifi for everything.

Galaxy Note 5 N920W8- Wifi Cuts In And Out

Wicked wakelocks and WiFi issues
Just yesterday I started having wicked WiFi issues, where both 5GHz and 2.4GHz networks would connect, then immediately disconnect, then connect again a few seconds later for it to just do the same thing, over and over. It keeps sending reports everytime it does it. I haven't factory reset though, but I'm going to have to.
Also, I keep getting insane wakelocks. Android OS is the worst, causing 7h+ of wakelocks in a 10h day. Google Play Services is pretty bad too, around 6h+ in that same 10h day.
Anyone else having major issues like this with their Note5? I have the N920W8 model, which I can't really find any info about anywhere
Im having similar wifi issues. Initially trying to connect to my 5ghz N home network (wpa2 psk) connect attempt, drop, connect attempt drop rinse and repeat. After a while it connects and stays connected, however, connecting to any web pages is painfully slow (like a super slow dns lookup), and i frequently get failed web page loading errors or failed to download apps from teh app store. Wifi calling is useless in this state. The same thing happens on an open hotspot network at work (2.4ghz) and the corporate (5ghz n) network. The note will ususally eventually drop wireless and force me back onto LTE. I looked at my data counter after just 3 days, and had used 27gigs of LTE, which is more data than I've used on tmobiles network since last year. Had some spotty wireless issues with teh note 4 rev 3 5.1.1 as well prior, but only had that phone for about 10 days before swapping for teh note 5. Prior to that I had the nexus 6 and no wireless issues on the same networks.
J'ai le même problème avec le 5g damn!!!
Luckily i have a dual dualband router, I set up the alternate AP 2.4ghz N wpa2 psk and the phone appears to be working fine at the moment on that network.
I ended up factory resetting and it appears working for now. A static IP address (DHCP reserved in the router) seemed to help.
Another issue I have though is when disconnecting from WiFi and connecting to mobile data, it seems to have DNS resolution issues until I turn data off and then back on. Not sure if it's the phone or the carrier (Wind Mobile) but it's pretty consistent
Not seeing these issues on my W8.

I'm just having dreadfully slow WiFi on my att model, but it doesn't drop connection
Dial *#0011# and click "wifi settings" from the menu at the top right corner. Turn off power saving mode and restart the phone, see if that does the trick.
If not, google search "note 3 wifi issues" and/or "note 4 wifi issues"and look for answers there. In all likelihood the problems that are being experienced with Wi-Fi on the note 5 are similar to the Wi-Fi issues that the predecessors experience when they launched.

It's Lollipop. It's a known bug in the software since Nov 2014 and Google hasn't addressed it. I too had issues with my WiFi when I first purchased it. But I found the work around. The bug is in the security software. The WpA2-PSK with TKIPS or AES which is a catch all, reeks havoc on our WiFi chips. It doesn't allow the phone to have proper DNS addresses resulting in severely slow internet or dropped connections.
Solution: Change your security standard to WPA/WPA2-PSK without AES or TKIPS.

Is that a phone setting or a router setting?
Hey guys,
I've got an Australian Samsung note 5 that has wifi problems. It started not working all of a sudden so i decided to go along with it but after a while i felt the need to try and make it work again. So i went into recovery mode and factory resetted (thinking that it would help) but then on the boot up after i came to the setup screen and found out that i was screwed. The samsung setup screen doesnt let you go past the setup screen without any wifi. Please help, i wanted to post a thread but im new to this community so i am restricted.
Thanks
p.s wifi networks can be detected but only when the phone is held right next to the router.
I fixed same problem of wifi, its a setting in phone, but you need to root phone, its system setting in system folder.
Any updates on this? Im running one 920g completely stock and another 920g with hybrid n7 port v9. Both have this same issue.

Having a major problem with wifi

The first few days my WiFi was functioning just fine. Now it seems no matter the network, if I try to connect it just doesn't happen. It will show connecting under the network for a split second, and just appear to stop trying. Anyone else having this problem? It's really bugging me that even my home WiFi will not work on this phone. I've tried forgetting the network, restarting etc. My note 3 is having no problem but it's just getting nowhere on my 5.
Mine does this sporadically but eventually connects if i toggle wifi a couple times. I cannot replicate the issue or narrow it to a specific router - happens at home and at work.

constantly looses internet connection only Aeroplan mode helps!!!

This is drives me nuts!!! Connection status showed as H+ and very often suddenly internet dissapears!!! And it's not going to work again before I switch all phone to Aeroplan mode and back!!!
Today I thow my phone at a wall Hoping to break it to have a reason to buy a new one without this problem.
Anyone else?
What mobile provider do you have, and does it happen in more than one location so it's not just an unstable transmitter in your neighborhood?
Skickat från min ONEPLUS A3003 via Tapatalk
Yes it happens when Im at home, probably with not so strong signal. What seems to be the the bug is that signal status in systembar shows that all is well with connection. But internet is absent. I use two sim, and it happens at all combinations of slots
Probably a solution to this will be a script that periodically check some online url and switch Aeroplan mode on/off if internet is absent.

Meaning what exactly? Just having the H+ symbol, or showing a bar or 2, does not mean much. I often will get a bar or reception showing on this phone when in remote locations, where there is no usable data signal. My wife's iPhone is the same way, shows that there is a phone and data signal, but no actual internet connection. The signal is present enough for the phone to see it, but not strong enough for any data to get through.
Go to phone Settings>About phone>Status>SIM status>Signal strength; and see what the actual dBM signal strength reads. This is much more reliable than any of the signal status indicators.
Thank you. Buut problem is that Android don't recognize that internet is lost before I switch to Aeroplan mode and back. I can wait for internet forever but as soon as I switched it connects immediately....
Really hate this piece if **** of a device!!!!!!!!
Do you still get this running on LineageOS 16? Can't say I've experienced this, running LOS and with keep mobile connection enable while on wifi-setting enabled in advanced development options menu.
Unless it's specific to your operator/mobile network. Have you checked your APN settings? Try deleting them and re-create from scratch.

Mi 9 bad reconnection when low signal on mobile network

When I am using a mobile network (both 3G and 4G) and the signal is low, sometimes I lost connection (That's normal), but the stange thing is that phone don't reconnect soon and it remains offline. I have to manually reboot or enable/disable airplane mode... and the signal come back.
I'm using Mi 9 for about 5 months. I am on the last firmware and even on old versions same thing...
Anyone has got similar problems?
Hi i have also some problem with my connections, I am from Germany I got my Mi 9 since a week (Rom was Global Europe 10.2.30 EEU) now I have the Global Rom (10.2.13) but this is also no solution.
Sometimes it shows me a Network but I tried to call my girlfriend and it has no dailtone, also it shows me network but I can't receive calls, same problem I have with mobile data, it shows connection but then it isn't connect to the internet.
if I switch off the mobile data connection and switch it on then I have normal connection.
I hope there will be a fix in the next update....I heard that some people have that problem.
Mine loses signal sometimes on the subway but reconnects by itself in 30-60 secs, i find that a bit slow but overall I think it holds onto the signal better than the phones i had in the past. This is the type of issue that would be solved in 1 month at most but here we are, an update almost every 2 months that "optimizes" one thing and weighs in at 500+ MB.
Mine have the same problem. When I'm on the subway it lost the signal and when I go out to the street again I have to enable/disable airplane mode to get signal again, because it can't connect automatically like a normal phone.. I'm from Mexico and I have Global ROM 10.2.13.0

I have a similar problem. Where I work the phone goes from 4g to 3g, to avoid this I open the phone settings 1 (by entering * # * # 4636 # * # * on the call keypad) and switch from lte / td-scdma / umts which is default option to only lte.
The problem remains the same when the phone loses the line and then finds signal again, because although there is signal after I do not receive photos or audio from wa or cannot I access the services of play store for example and I have to switch to default option again...
I'd like to know if there was a method to increase the power of the antenna module even just a little with root permissions ...
I have a similar issue, especially when I am driving car - I am from Germany.
When I start driving with Google Maps open (to have an overview of the traffic), after about 30 minutes my Mi 9 loses connection and won't reconnect, even if I switch on/off airplane-mode etc. This does not happen every time, but relatively often. To get back network connection I have to restart the phone.
About 2 days ago when I was home I lost connection again. Google Maps was still running. After closing the app my Mi 9 immediatly connected to network. That may have been coincidence, but next time I will close Google Maps if my phone loses connection again in the car and will report here.
I am on Xiaomi.EU 9.9.26 Android Q (I just installed *.27 v2), had the same issue on different Xiaomi.EU Android P releases.

It happened to me several times and I can't understand why ...
In this case the connection seemed to be good too, I had all the signal notches in Lte, but in reality it was absent.
I had to restart.
Known problem it seems...?
Hopefully Xiaomi will fix it soon.. wonder if custom ROMS have the same problem

So, as I said I report back.
Today again after about 30 minutes my Mi 9 lost connection (0 bars). Again at about the same region. Probably the connection is bad there. However, my Mi 9 didn't reconnect even after few minutes (sometimes I waited 5+ minutes and IT didn't help).
I closed Google Maps and another App, which requires GPS. Nothing happened. Then I deactivated GPS from the quick menu and my Mi 9 connected immediately to the network with full bars.
I have "o2" as network provider.
Xiaomi.EU 9.9.27 v2 ROM.

I changed to LTE only, and use it for some hours...
It didn't help. Same as before.
Thanks anyway

Yeah, I know, For me is the same.
When I lose connection I've to change to LTE, When it happen again, I've to do it again so I come back to default option.
I do this to avoid restarting the phone and to be faster, but the issue remain anyway...
But remember, When u're in "only LTE" option, you will not able to call
Workaround is change to 3G connection preference
Hi everyone!
I have the same issue and after lot of things that I have done, as change MIUI to Global version, now I can use 3G without problem, but if I try to use LTE/4G after some minutes using GPS in high accuracy, LET connection turns OFF.
So, my workaround is change to 3G connection preference when I need to use Waze, Maps or any other app high accuracy.
I have the same problem too, and I always have to reboot the phone to get the data/wifi to work again. But just a minute ago I had the same problem and I just killed all tasks in recents and the network came back without having to reboot. May be coincidence or I'm on to something.
From experience this problem should have disappeared for quite some time now.
I have always been using EEA ROMs. I believe I have not seen this problem at all in MIUI 12. It has been such a long time since I last saw the problem I don't really remember if this was fixed during the MIUI 11 era.

Which ROM/Firmware are you using?
Try disable and enable airplane mode instead of rebooting
