@superdragonpt Due to the fact that I'm not allowed to post to the original ROM thread, I'm providing my feedback via this channel.
As already reported under the thread "Jiayu S3 Adv - AOSP N stable 8 - automatic reboots, wifi, camera and sound profiles" (https://forum.xda-developers.com/jiayu-s3/help/jiayu-s3-adv-aosp-n-stable-8-automatic-t3563631) the phone sometimes reboots automatically and I had to enter my SIM pin again.
The problem still persist with MadOS stable 10, but I think I've now catched a situation in which the reboots are happening more often. Although the wifi connectivity has been improved with the latest release I found out that the phone sometimes freezes if an app is running in foreground and a wifi connection is automatically established or a wifi connection is lost in the background. I hope this will help you in one or the other way.
Concerning wifi connectivity I've also realized that a connection to a known network is sometimes not established automatically, although I can see available networks in the "Wifi Analyzer" app. I'm also able to connect to one of these networks by forcing a connect.
@superdragonpt I think I can provide some additional information about automatic reboots. Last week I've been at a location where the primary wifi network was WPA2 secured. I realized that automatic reboots only happened two times in eight days.
Back in my usual environment, where an EAP secured wifi network with Radius authentication has been installed, automatic reboots happen at least once per day. I come to the conclusion that the used wifi security protocol impacts how often an automatic reboot happens.

Last week it was time to investigate further on the annoying reboots and the wifi network connection problems. I realized that many people reported wifi problems after upgrading from Marshmallow to Nougat and when trying to connect to EAP secured wifi networks in e.g. company environment. Some people wrote that setting the following parameters have solved their wifi problems:
EAP method: PEAP
Phase 2 authentication: MSCHAPV2
CA certificate: Do not validate
I've also used that settings in the past but without any positive impact on the result.
Therefore I decided to add my CA root certificate to the wifi setup, using "Advanced -> Install certificate". It was a big surprise as I saw that wifi connections were established much faster and that no automatic reboots happened during the last 4-5 days .
My conclusion is, that although the CA certificate parameter has been set to "Do not validate", the certificate check is not fully disabled which causes the mentioned wifi problems and also automatic reboots, because of wifi reconnection attempts which might have happened in the background.

I'm running the official BTU 4.3 release on my I9505
I've noticed two issues with 4.3
a) Wifi
From time to time, perhaps daily, my phone loses connection to my home wifi. I get a notification which says something about being disconnected -- don't remember the full text. When I click on it I get taken to the list of wifi networks and underneath my local wifi network it will say "Sign-in is required".
It may be working as designed - checking my newish BT HomeHub 5 I can see the PPP session recycled twice overnight. Oddly this was initiated by upstream admin according to the logs, not a vdsl failure.... since the hub will intercept pages when ppp is down it's possible this caused the confusion
b) Security policy
I sometimes see a notification that an app required access to system, but didn't have permission - yet when I click on the notification I get taken to a full list of apps -- how do I find out which one was trying to be naughty?
The WiFi problem can be quite annoying.
I think this is not an improvement over the previous functionality.
The idea seems to be that as soon you have to manually log in to a WiFi network Android switches to the cellular connection to make sure you are always connected.
The thing is that at my work place this means every time I get somewhat out of range of WiFi (elevator, toilet, staircase) and walk into range my WiFi stays disconnected until I remember to reconnect it.
I only have to actually sign in once a day, but as Android thinks it is a network you have to sign in to it will not automatically reconnect to that network.
Meanwhile the phone is using up my data allowance....
Hall,
I got a TM530, rooted with Towelroot, no modifications otherwise.
When trying to connect to phone's WiFi Hotspot im getting asked for the password, after entering it there's the message "Connecting..." for a second or so - but I won't get a connection [emoji17]
A few days ago this was no problem - I'm a bit lost here.
My phone's running with Slimkat ROM with two weeks old weekly build, didn't change anything there, too.
Changing Hotspot setup and deleting the connection from WiFi menu on the tablet led to no success either ?
Any hints anyone? I'd appreciate

Pretty common problem tethering from a phone to tablet with the native tether method due to its lack of settings. Download the app WIFItether Router by Fabio Grasso. When you set it up, under "hotspot/tethering settings" make your SSID whatever you desire, use wpa2-psk for encryption type, then set a password, and desired channel (I usually use 11). Then under "device settings" for Interface select wlan1, under method use Method 3-HostApd, under drivers select nl80211, select WiFi -g for wifi mode. Then under "tweaks" check MTU adjust and also check HostApd patch. Now go back and select "enable wifi router". That should solve your issue.
This started Feb 3rd or 4th. The phone will connect to the wifi network, with a good signal. It will then re-scan every 5 seconds or so. This is causing all sorts of data transfer issues from downloads freezing to apps losing connectivity while running.
I am running on Verizon.

I am now running Android 5.0 but had NOT updated to 5.0 when this problem started.
I scoured google a bit and found an ATT forum that is essentially reporting what I am.
forums.att.com/t5/Samsung-Discussion-Support/Samsung-Galaxy-S5-Wi-Fi-Connectivity-Problems-After-4-4-4-Update/td-p/4190704
All other devices on the network are operating without issue - phones and computers - as was mine until now.
I have power cycled everything.
I have checked the routers settings.
The phone has been power cycled several times.
The phone has had every wifi setting that would be causing this scanning, that I know, disabled.
The following are off in Wifi > Advanced:
Wifi notifications
Passpoint
Always allow scanning
Smart network switch
I then, after the above, updated to Android 5.0. The issue still persists. Help me please.
My device does this, too. Cant say I have ever really noticed, I dont know if it has always done this or not.
I am not experiencing any issues like you describe.
Now that I think about it, I think it will always scan at a set interval when you enter the Wifi settings. It assumes you are looking for a network to connect to. I doubt its scanning when you are not in that setting.
I had this problem the other day. I went to wifi settings and had it forget the network and then rebooted and reconnected to my wifi network and it seems to have resolved the issue. others have just switched airplane mode on and off and this fixed it. good luck
In the past week my Galaxy S5 (SM-G900V - Android version 5, Kernal 3.4.0) has lost the ability to connect to the internet a few times when wifi is on (under wifi, it appears that it is connected successfully to the wifi but when using the internet I get an error message about DNS not working).
This first time it happened was at at home and I thought that maybe my router just needed to be reset (which didn't fix the issue) but it happened at work today.
Both at home and at work, the only thing that I could do to fix the issue was restarting the phone (resolved the issue at both locations).
I tried all of the following suggestions with no luck:
Turning wifi off and then back on
Making sure that 'Always allow scanning' and 'Smart network switch' were both turned off on my phone
Choosing the wifi network on the phone and 'forgetting' it and then connecting to it fresh
Setting the DNS servers on the wifi network of the phone to use a static IP address and static Google DNS servers
Trying a different browser on the phone
The only thing that has resolved the issue once it starts is to restart the phone.
Any other suggestions?
OK - I use LOS 14 which has been more or less fine ( a few documented niggles on the thread, but OK up to now)
About two weeks ago, without any obvious changes my WiFi locks the entire router - resulting in a router reset. Router is a "TP Linke AC750 Wireless Dual Band Gigabit Router"
I did initially think this was triggered by the IP lease expiry, but set IP addresses or maxing out the lease time didn't seem to work. But it does seem to occur when the phone reconnects
I have increased the log settings - see screen shot - with "network_selection_disabled_association_rejection=3"
Also, in the Logs there is WiFiQualifiedNetowrkSelector: <ssid>: <mac of router> is on blacklist
Looking around the net this error seems to be down to the phone blacklisting the router due to poor connections - but I didn't even leave the house today and it hit
I've tried lots of tweaks to WiFi, keeping it on, keeping it off. I have now just moved my Routers channel to a less busy one - but I have no idea what is causing it.
I have removed all the apps that I can recall installing just before this happened.
ROM is as it is and was stable for months before this happened - Router firmware is up to date and went through factory reset - can't do that for phone for a week as it is my key generator for 2 factor authentication to work network and if I zap phone you can bet work will need remote access before next week!
Ideas anyone?
Cheers
