Hey, Samsung finally responded to the thread!

 

Oh... it is the same advice that we have all tried (multiple times) months ago? Bummer.

Tons of issues here, too. Dropouts are around every 5 min but are irregular. 

Things I've tried that did not fix it:

On my access point (Unifi AP Lite 1x, no mesh):

  • 5 Ghz only network
  • 2.4 Ghz only network
  • Changed bands for both radios
  • Disabled automatic optimization, band steering, advanced device optimization

 

On the phone:

  • Static IP/DNS
  • Private DNS off
  • Private DNS set to "automatic"
  • Private DNS set to cloudflare's private dns server
  • Google location accuracy off
  • Location off entirely
  • Resetting network settings
  • Resetting all settings
  • Factory reset

I gave up and talked to Verizon for a refurbished replacement, and on Android 10 for an entire day it had no issues. Updated to 11, and wifi dropouts began immediately after restarting. At this point it looks like there's no user fix.

25 pages in and nothing from Samsung? Let's see I'm using a galaxy note 20 ultra my wife in on a galaxy s20 plus my 3 boys are on galaxy s20 fe phones and I'm really debating on switching to iPhones. I've been on Samsung phones since Samsung 4g infuse and never left because I felt they always tried to give the best product but now that feeling is gone. If this is not fixed soon I will move on.

Hate to reply to my own comment, more updates;

Talked with Verizon and asked them to submit a bug report from their end to Samsung, as well as submitted a bug report through Samsung Members (no response, although it's only been a few days).

Other things confirmed to NOT help:
- Disabling random MAC (necessary in order to set up a static IP while still using DHCP for other devices but worth noting)
- On the AP side, disabling or enabling other Unifi features such as blocking broadcast/multicast traffic (with gateway and phone whitelisted), unblocking multicast traffic, enhanced 802.11r roaming, etc.

Something that did help was using my desktop (Windows 10, has a wifi6-enabled NIC) to provide a hotspot for my phone. There's an incompatibility somewhere between the Android 11 update and my network setup, potentially with regards to IPv6 DNS and/or DHCP, which I cannot currently manually configure due to being forced to use my ISP's router.

I'm having this issue as well and it is driving me crazy. Went through all of the troubleshooting steps already as well.

So do you want ALL of us to send you that information?

 

Because if so, your inbox is going to be FLOODED with messages.

 

This is happening to many many many peoples phones and NOT just on this board.  Other message boards as well.

just got my Note 2- Ultra yesterday and I've been experiencing intermittent wifi connection. at first I thought it's our wifi connection but found out later on that this is the only device that keeps on disconnecting from time to time. tried all the possible troubleshooting on the internet but no luck.
