Upgraded 3200ACM from previous version 3 February 2021, no reset of settings, web flash image.

So far so good, no issues.

There's a new warning message at boot but I don't think it's a deal breaker since DNSSEC is working:

Upgraded WRT1200AC v1's from r45667 to r45677 using Firefox 85.0 (64-bit) running on Linux Mint 20.1 OS hardwired via Cat6.

Successful update and reboot. No reset, nothing disabled prior to update, uptime approx 15 hr, wired/wireless connected, vpn up immediately (Expressvpn). I do not use NAS. SFE and IPv6 are always disabled. OpenVPN client/DNSMasq, QoS with PIE always enabled. I do not have any Apple devices.

Kernel Version Linux 4.9.254 #2388 SMP Thu Feb 4 02:05:53 +07 2021 armv7l

No issues with a routine update session.

I almost posted "why are there two threads for this build with different dates?".

1900ACv1 here. Up about 8 hours. I have had WiFi hangups on both Android tablet and iPad requiring toggling of WiFi. I use my tablets pretty much for streaming video content only.

I have a Windows laptop that experienced some temporary slowdowns, but it recovered. I usually don't have issues with this laptop on firmware > 44048, so it might not be related.

Haven't gone back to 44048 yet.

Upgraded my 1900ACSv1 via Safari from 44048. Did a complete factory reset and re-entered my settings manually. No issues with upgrade.

Problems with Apple devices: Wifi stays connected but most traffic stops flowing. Speedtests on multiple Apple devices can trigger it pretty quickly, as can normal usage such as opening the lid on your macbook- all of a sudden the ping stops but the wifi connection is strong. One time, the ping stopped but I was still able to run speedtests - very strange. After watching ping times for a while, you can see when it starts to get wobbly - ping times go up - a few pings are missed - speedtest performance plummets - and then eventually, no traffic is flowing. Recycling wifi on the apple device fixes it right away.

Couple hours of testing this morning: I tried WPA3 and then disabling wifi security completely, but the problem remains. Next, I created a separate SSID to ensure just my iphone and macbook were the only two devices on the 1900ACSv1 - this helped but I eventually was able to trigger the problem. I also shutoff my two chromecast audio devices thinking they may be the culprits, but the problem still remains. IMHO, when you have multiple Apple devices talking at once, using their location services all at once, the problem can be reproduced in seconds or minutes.

44048 is the last good release if you have Apple devices in your environment. Something broke with 44085 and 44112.

Linksys WRT1900ACSv1: router mode, hardwired ethernet lan to a WRT3200ACM. WIFI: 2.4ghz: NG-mixed, 20mhz channel width, channel 11, WPA2-CCMP-128. 5ghz: AC/N mixed, 80mhz channel width, channel 36+upper, WPA2-CCMP-128.

Clients: Apple MACOS x 4, IOS x 4, Apple TV, Chromecast Audio x 2, Eufy doorbells, Lutron Caseta, Axis Camera, Samsung TV, Nest thermostat, EtekCity outlets (Espressif)..

Is there a ticket # for these WiFi stoppages?

I searched in SVN, but couldn't find anything obvious.

This build is problematic for wrt32x router. After web upgrade, 2.4/5 Ghz wireless cannot connect after few hours. Also, the build causes webpage slow and freezing.
