Wifi keeps disconnecting - Samsung Galaxy Note 9 Questions & Answers

Hi all,
Hoping someone can help me out. I have the 512GB version and been having a hell of a time with my wifi randomly disconnecting and reconnecting. Sometimes it wont even reconnect due to "authentication error". Anyone have a fix or been experiencing the same issue?

Problems with just a particular router or any WiFi connection?

I haven't used any other wifi but all my phones are fine on my home router except for this one.

What router is it? Check/experiment with the settings on it.

Yea, I did that on Friday. No go, thanks for the reply though.

I have the same trouble with my note 9, wife's note 8, sons s9, daughters s8 and I am using Samsung connect home pro wifi with 5 AP in my system. Laptops and TVs all still work...just the phones randomly have trouble.

Have a look at wireless mode and see if changing that makes a difference.

Wifi issues

So I'm having Wifi Connection issues on my Mile stone. I'm running the Lastest STABLE version from Miui.us. Problem is I can connect but within a min or two of connection it looses connection and says wifi out of range even if Im standing right next to it. If I forget the connection and restart my router it will find it and connect again and do the same thing. I've tried my cousins Samsung Vibrant on my wireless router and he doesn't have any issues so I know its not the router itself. Any Idea's on how to fix this guys?

I've had some success with changing the wifi sleep policy in the advanced tab of the WiFi settings.

Yeah, 1.9.9 is a beta development build, but he's just remarking how stable it really is.
Hi, I have the same problem with WIFI, I cahanged the slep policy, and when I activate Wifi it's starting scanning for nothing, no wifi Network appears and when I can connect, after a whie it's disconnecting itself and doesn't reconnect. Somebody knows the problem?..I'm using MIUI android v1.9.9
I'm not sure, I updated to 1.9.16 and I'm having some issues with mine but not as bad. The weird thing is wifi won't work if the mobile data network is enable, when i turn that off my wifi will connect but if i get even like 10 feet away from the router it starts having connection issues and sometimes when im right next to it. But no where as bad as it was before.

[Q] Wifi connection

Hello forum! I'm having an annoying issue with my I9070: when I connect to my domestic wireless LAN the cellphone regularly accesses the Web and web-based apps work fine. But if I leave the phone inactive for, say, 10 minutes, it won't be able to access internet sources. The strange thing is that it still reports being connected to the LAN: to regain the connection I have to turn off the Wifi and turn it on again.
This is annoying because those apps that work in background can't actually access Internet and thus won't function regularly!
I've looked for solutions on the Net: I found that Android phones have troubles with WPA-PSK-protected wireless networks, such as mine; I found suggestions regarding the code *#001#* to access a debug screen where to turn off Wifi sleep mode (but for heaven's sake, I couldn't be able to find this goddamn option!); somebody suggested to switch to static IPs on the phone, to no avail.
If it can help, I have an unrooted phone with Gingerbread 2.3.6.
Try to go to Settings - Wi-fi - Advanced - Wifi always on > there check always.
I hope it helped

Yep, the setting was already checked.
I can't seem to understand if the problem is in the router or in my smartphone. Hope it's not an hardware issue.

Do you have some battery boost application installed or something else what could affect turning wireless off? If you have, try to uninstall it.

Only battery related app is Battery Widget from Elvison, and it's just a widget showing me the charge left. Don't think it could be the problem, it doesn't feature any battery saving or battery boost function.
I'm experiencing exactly the same problem, but I only have this using my home Wifi.
Looking for a solution also!
EDIT: Do you have this everywhere but also just at one specific place or router?
What brand is your router?

Sorry for the delay of my answer.
I noticed that this happens at my girlfriend's house too, and also her wireless network is protected via WPA-PSK.
My brand of router is Sitecom, while my girlfriend's is DLink.
I'm using a sitecom at home too.. Guess the problem is more in the router than on the phone.
I've already been through the routers setting but unable to find anything..

is there any way/tweak to get more speed from the existing wifi connection in galaxy s advance??

Wifi disconnecting problems..

Is anyone getting the wifi problems that the other versions of the Note 3 are getting? Preferably when it says the network was disconnected for being too slow or something like that? I know it happens on the T-Mobile, Verizon, and International versions.

Mine doesn't disconnect but it says wifi signal is unstable, then I looked in settings when this happens and it says wifi signal strength VERY STRONG, I'm sitting 10' from my router and I know damn well the the signal is strong as it says 72mbps. Lots of issues with wifi signals are popping up in the N3 sections, not good.
Yep, same as Quickvic30

Go to wifi advanced settings and uncheck Auto Network Switch. It appears the phone will "test" the speed of the wifi network to your 4g and picks which is faster.

Hey all,
I realized that the wireless issues were all where there are at least access points broadcasting the same network. The signal indicator flickers back and forth between solid and weak, and I think the wireless manager is jumping back and forth instead of sticking with the stronger one. I installed one"WiFi Manager" from Play store and the connection is more solid. I haven't rooted my device yet, so this may be the best answer until a patch shows up.
Let me know if it works,

Hello I was having this problem I had to remove my ad stop program and everything starting working normal again adblockplus to be exact but that fixed issues with mms messages and the wifi.
Yes- nothing but problems with wifi dropping and reporting as slow/unstable. Rooted on AT&T MI1. Various AP's, not specific to any one location. Basically renders wifi useless.

Yall- this issue has been bugging the hell out of me. Finally tried something I found buried in a few other forums that immediately fixed the spotty connect/disconnect and wifi data stalling errors.
Enter into the service configuration mode by dialing *#0011# and hit the menu key- touch "wifi" and turn off "wifi power saving". Reboot. After having tried everything else I was skeptical but I can confirm (in my case) it worked like a charm!
Hope it helps someone else.

Great info! I just did it and rebooted so I will report back with the results. Thanks!!!
Another possible fix for you guys.. go into wifi in settings..hit menu then click advanced. Inside advanced make sure to uncheck auto network switch. Reboot and voila.

I've been using that method for most of the day, and I've noticed some good results with WiFi. Unsure how it's going to affect battery life yet though lol
auto-network switch
I didn't have to reboot, but disabling the auto network switch did help. I kept getting the 'unstable messages', and I finally had to click the "don't show this again" button and hit 'cancel' so that the OS would stop trying to help my be re-enabling the auto network switch. So, the question is, is this just #LTE2fastprobs, or are there real wireless n/ac issues that make this phone less than desirable?

Sony RX100 ii connectivity

Hi anyone have experience with connecting the n8 to this camera? Using the sony memories software it tries to connect but disconnects immediately. Any ideas folks.
I have an A5000 but i believe the method should be same.
When using wifi transfer i set it to wifi direct rather than through a router/access point (never had any success with using wifi router), when connecting directly to the camera the phone will complain about no internet access, make sure you pull the drop down and select stay connected anyways (otherwise the note may drop the connection so i can reconnect to your router that does have internet connection)
Found the solution I had to disable mobile data. Only found this out this by checking whether it worked on my tab s3 and it did so was a matter of deduction. Thx

strange mine works fine with mobile data on, do you have the switch to mobile data when ever your wifi internet connection is slow or unstable turned on in the advance wifi options?

nope thats off. weird huh

Reboot is always required to use internet.

This is very inconvenient. If I disconnect from WiFi or LTE, then reconnect, apps do not detect the netwoork unless I reboot first. Has anyone experienced this problem or have a solution?

Never thought of doing that. I don't think that would be a complete solution though, because on LTE the issue still exists; it is not just a problem on WiFi.
Are you using some extreme power saving options/solutions/aps etc etc ?

Last nite I installed the OTA update of android 9. Since then the problems have been non existant. I will continue to update this post, and try all the tips I have been offered, if the problem returns.
I found the source of the problem. The VPN I use was preventing the apps from accessing the Internet.
