Welcome to Atheros r62966 beta release thread for reporting, feedback to developers and community benefit.
Please do not flash builds until installation is understood, risks involved and device specificrecovery methods.
Avoid discussions, create threads for questions, general problems or use search; this thread is not for support.
List router model & version or revision, operating & wireless modes & exact filename/firmware image flashed.
CLI Flash: 'cd /tmp' then 'wget {file URL}' (httponly) or 'curl -O {file URL}' (http, https, ftp) 'write {file} linux' then 'reboot'.
Issues, observations, and/or workarounds reported:
• WebUI: Clear history or use a portable. Temporary cache bypass: Ctrl+F5, Cmd+Shift+R or new private window/incognito.
• Please report findings with steps needed to reproduce, configuration, clients, output, logs and important information below!
Important:
• Detail issues & relevant configs, logs: syslog klog 'dmesg' 'cat /tmp/var/log/messages' nvram set console_debug=1, serial.
• Firewall NAT: 'iptables -vnL' 'iptables -t nat -vnL' 'iptables -t mangle -vnL' & 'cat /tmp/.ipt'. Debug Analyze: stracetcpdump.
• Gremlins: reboot. cold boot. Reset & reconfigure not restore backup. Search Trac & discuss in forum before opening tickets.
• Include operating & wireless modes (e.g. Gateway, Router, AP, SB, WDS, Mesh) and applicable configurations to reproduce.
Router/Version: Linksys MR7500
File: https://download1.dd-wrt.com/dd-wrtv2/downloads/betas/2025/12-06-2025-r62966/linksys-mr7500/dd-wrt-webflash.bin
Kernel: Linux 6.6.118-rt29 #4713 SMP Fri Dec 5 17:09:47 +07 2025 aarch64
Previous/Reset: R62924 using GUI and no reset
Mode/Status: Gateway device - NSS-ECM - NAS/Local FTP/Samba - OpenVPN server - DNSCrypt - A/P [WLAN0 : 1 SSID, 1 VAP] [WLAN1: 1 SSID, 1 VAP] [WLAN2: 1 SSID]
Issues/Errors: DNS traffic from Virtual access points are blocked by NFTables, on going low memory.
Here is a look at memory:
Code:
total used free shared buff/cache available
Mem: 380164 294440 9224 0 76500 67616
Swap: 524284 0 524284
I have read multiple posts that mention Virtual Access points do not have internet connectivity. What I discovered is the VAP's have internet connectivity, but NFT firewall is explicitly denying DNS traffic from Virtual Acccess Points. Here are the four rules stopping DNS traffic:
I realize it says "...do not touch!" I rewrote my firewall rules to use NFT.
I modified my firewall startup script to remove those four rules anyway. Now my guest network functions as expected.
Yes I'm aware the GUI inserted those rules. That means I have to remove my modifications from the firewall script and reboot before modifying the guest network in the GUI.
FYI - I setup my simple Guest Network with 1 SSID on wlan0.1 & wlan1.1 using Guest WiFi + abuse control for beginners from the WIKI.
Yes, there are better more complex methods of creating a guest network, but only having guests/relatives actually on my network four, maybe five, times a year this method is more than sufficient.
WOW! It certainly was nice to flash to a new build using the GUI without resetting, involving the OEM firmware, and manually reconfiguring every time. Thank You.

Notes on configuration: Used for Wifi Lab (no internet)
Errors:
Enabling NSS on R7800 still kills WAN. Not sure why NSS options are even there, should be disabled until fixed or completely removed if fixing is not possible.

Went back to r62540. Router would reboot every 45-60 minutes _________________ My $55 wireless backhaul Mesh setup (r62540):

NSS has been broken on R7800 since DSA was added in r60832. I have also asked on occasion if this is likely to ever get fixed, but never gotten a clear answer.
