Welcome to x86 / x64 r63020 beta release thread for reporting, feedback to developers & 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.
DNS Resolution is working again Ty very much for fixing this devs =)
PHP not working currently, due to missing opcache.so module.
Code:
Warning: Failed loading Zend extension 'opcache.so' (tried: /etc/php/modules/opcache.so (Error loading shared library /etc/php/modules/opcache.so: No such file or directory), /etc/php/modules/opcache.so.so (Error loading shared library /etc/php/modules/opcache.so.so: No such file or directory)) in Unknown on line 0

Router/Version: industrial PC N4000 4GB RAM, 2*intel i226-v
File: dd-wrt_x64-webupgrade_full_vga_2GB.bin
Firmware: DD-WRT v3.0-r63020 std (12/10/25)
Kernel: Linux 6.12.61 #515 SMP Wed Dec 10 02:31:22 +07 2025 x86_64
Mode: Gateway, SFE disabled, Wireguard for external access, WAN (ETH0) (PPPoE/VLAN7) to GPON Modem, ETH1 to LAN, Automatic Drive Mount disabled - using own mount script for USB Disk, nfs to access USB3-ext4 SSD, Force reconnect 5:00 in the morning, using my own local NTP, CPU governour set to ondemand by script, Ignore WAN DNS, Recursive DNS Resolving (Unbound), using NAT66.
Reset: No
Status: Okish. NAT66 with ULA: Websites testing for IPv6 report IPv6 not to be available (this was working in releases up to r62606). Nevertheless traceroute, mtr, ping and nslookup or dig aaaa are working for IPv6.
"Uploadspeed of updatefile capped" - first observed in r62268 std (10/09/25)
The transmission speed for firmwareupdate from browser towards this router is slow. With older releases takes a few seconds, with newer 300s++ making it tedious to test or flash back and forth to review possible solutions.
This happens with firefox, firefox nightly, both tested on X86 or aarch64 and debian13 aarch64 chromium and android duckduckgo.
Strange, since I can copy files to router or download files in its /tmp way faster (NVMe drive!).
Also I tested this on several PCs, all wired and set to 1GBits/s.
WAN Speed still there, only speed for firmwareupdate is slow.
IPv6 throughput is hindered for LAN facing eth1 by "rx-gro-list" being set to on.
Code:
iperf3 -c anyiperfserver -6
sports max upstream when used on this N4000 router. It connects through its ETH0 to WAN, using PPPoE VLAN7.
Code:
iperf3 -c anyiperfserver -6
sports 1-5 Mbit/s upstream when used in my network connected to its ETH1.
This behaviour started unbeknownst to me.
Possible this is related to me using nat66 in my network.
