Issues:
• There may be remaining issues for Samba (for example NTFS), with frequent updates.
Important:
• If reporting issues provide applicable info: 'dmesg', 'cat /tmp/var/log/messages', syslog, serial output, strace, tcpdump etc.
• For firewall NAT or WAN issues provide 'iptables -vnL', 'iptables -t nat -vnL', 'iptables -t mangle -vnL' and the /tmp/.ipt file.
• Search existing SVN tickets before opening a new one. Before reporting, reset and manually setup (no nvram backup).
• Be sure to include operating and wireless modes (Gateway, AP, CB, etc.) along with relevant configuration information.
Upgraded WRT1200AC v1's from r45229 to r45420 using Brave Version 1.10.97 (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 1 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.

No issues with a routine update session. Everything up. Did a random check of GUI tabs and found no issues. Will do some streaming later and update post if I have any issues.

Router/Version: WRT1900AC v1
File/Kernel: DD-WRT v3.0-r45420 std (01/13/21)
Previous/Reset: r45000 - no reset
Mode/Status: Gateway / Access Point
Issues/Errors: None so far.
Wired speed seems good. Tested connectivity on 2.4 and 5 GHz bands. No dropouts on Windows (Intel cards), Android, or iPhone. Attended several Zoom and Teams meetings while my wife streamed Netflix without any hiccups. _________________ __________________________

Upgraded my 1900ACSv1 from 44048 to 45420 via GUI with Safari. No reset.
Performance was great for about 10 minutes before my iphone froze up - it remained connected to the router but no wifi traffic was flowing. It fixed itself about 7 minutes later, but I was able to reproduce it repeatedly with speedtests or other apps. Clash of Clans seems to trigger it immediately My macbook also had the same issue twice - temporarily fixed by recycling wifi on the macbook. In fact, my macbook froze up as I was uploading 44048 to fallback. I was able to fall back to 44048 and restore settings from a backup.
Here are wifi settings I have in-common between 5ghz, 2.4ghz. Note I disabled protection-mode but this did not seem to help. IPv6 is disabled. Firewall is disabled. SFE disabled. STP disabled. DHCP disabled. QOS is disabled. It really is a simple config.
Works fine on my 3200ACM upgraded from the 01/01/2021 build.
Works on all devices including an old xbox 360 wireless.
Will report back if there's any issues. _________________ Router: Linksys WRT3200ACM WLAN0 and 1 have same SSID

ACK Timing normally is 500 or Less. 1350 means device is far far away from the wireless router around 675 meters away from the router.
Reading your post and checking my ACK setting I found it to be at 2000. I have no recollection of changing the setting since purchase. Apparently 2000 was the default at one time? Having no issues I will leave my setting at 2000 for now. Thanks for noting this setting default.
I might try 500 or the 0 setting mentioned in the wiki later just for fun "-Recommended setting is 0 for a household network. Which for Linksys users means DD-WRT doesn't use ACK timing at all."
