Welcome to x86 / x64 r62540 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.

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-r62540 std (11/05/25) (prev. DD-WRT v3.0-r62508 std (11/02/25))
Kernel: Linux 6.12.57 #379 SMP Wed Nov 5 06:58:01 +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: Working, three issues to add though. Those accumulated over the last releases:
1) "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 and more.
This happens with firefox, firefox nightly, both tested on X86 and 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.
2) "PPPoE does not autoconnect after first reboot" first observed in r62104 std (08/22/25)
Also subsequent reboots end in PPPoE does connect, does not connect, connects, does not connect... and so on.
--> always two reboots required.
Despite being setup to do so, the first connect has either to be done by hand or the router has to be rebooted one additional time.
If error is there Status --> WAN gives:
Connection Type PPPoE
Login Status: Disconnected
Access Concentrator Name: "The one used when connection was up before reboot"
Connection Uptime: Time since boot
IPv6 Address: fdXY (UlA I provide in firewall command with ip -6 addr add fdXY::/64 dev br0).
IPv4 Address: 0.0.0.0
Gateway: 0.0.0.0
Forced reconnect to a time set works, if connection was up.
3) 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.
