Welcome to x86 / x64 r62508 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-r62508 std (11/02/25) (prev. DD-WRT v3.0-r62418 std (10/24/25))
Kernel: Linux 6.12.56 #371 SMP Sun Nov 2 07:34:00 +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, a few things to add which accumulated over the last releases:
1) "Uploadspeed of updatefile capped to a crawl ~10Mbit/s" first observed in r62268 std (10/09/25)
Update via Webgui did not end after the usual "a few seconds" timespan, but it took the whole timer to count down to 0.
The transmission from browser towards Router did never max out 10 Mbit/s, according to iftop.
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)
PPPoE does not autoconnect after firmware upgrade and its reboot.
Despite being setup to do so, the first connect has to be done by hand.
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.

Router/Version: i7 4770k 32gb ram and attached five HDD drives for NAS
File/Kernel: x64 full VGA
Previous/Reset: YES
Mode/Status: Gateway, Router, NAS.
Issues/Errors: Not yet still testing. So far the ports that refused to work after disconnecting and reconnecting has been fixed. Realtek 8125b is working with the manufacture driver instead of the buggy kernel driver.
CML750 try this build. May have to use RUFUS or Physdisk write utility. I didn't bother upgrading from previous release. See if this fixes your issues.
EDIT: Uptime at 12 hours no issues yet. I have transferred at least 600GB to the NAS drive and no weird issues. Everything seems to be working as expected. Kodi, Windows and Linux versions work perfect. Samba/ksmbd seems to be pretty stable too.
I finally got around to installing this one. I did a clean install of the Full-VGA-2GB image on a thumb drive. So far no major issues after about an hour. It recognized the Intel X540 2 port card I installed. I purchased a couple of the 2 port x540 cards off of eBay cheap to test a 10 gbps connection with my server. It is working great so far with limited testing. I plan to purchase an Intel x710-T4L (which does multiple speeds including 2.5 gbps but is VERY expensive), if I deem the 10 gbps is worth it.
The only issue I am having is it did not recognize my Qualcomm Fastconnect 7800 wifi card (NCM865). It works in OpenWRT (at least the 2.4 and 5 ghz not the 6 ghz) with the ath12k-kmod and Atheros 7850 drivers. This is the first time I have tried it with DDWRT. I wonder if Brainslayer could add those to DDWRT? I use two routers as access points so it is not a big deal but I would like to try testing using wifi straight from the X86 setup. _________________ Optiplex 7060 with i7-8700, 32GB Ram, X710-T4L, i226 four port, & an AQC113 M2 slot card.

Brainslayer will need the output from using lspci command in the terminal to see what the hardware ID is for the WIFI adapter. Post it here and in the unrecognized adapters forum.

Thanks! I will work on that this evening. _________________ Optiplex 7060 with i7-8700, 32GB Ram, X710-T4L, i226 four port, & an AQC113 M2 slot card. DDWRT 64327 & Adguard Home.

My router is set to force reconnect its PPPoE connection each night at 5 in the morning.
Does anyone else see inadyn segfaulting then?
It gets restarted automatically and works without any problem afterwards.

I haven't seen any segmentation faults on my system. What is the system specs you have? Is the CPU overheating or overclocked?
The System is a small (~10*10*4cm) passive industrial PC.
Picture:
CPU intel N4000 / Celeron "Gemini Lake", 2 cores no HT.
RAM 4 GB DDR4
Disk 128 GB NVMe
2 USB3, 1 HDMI, 2 RJ45 (i226v).
It does not run hot, currently 42°C while idling at 796 MHz, no OC of any kind.
Its governour is set to ondemand. Even under load I have never seen temperatures above 6x°C.
I guess the other difference is that I am using DHCP and not the PPPoE. The other three differences is that I am using a 4th Gen i7 and DDR3 1600 32GB. Using MBR legacy and not the uEFI images. Did you happen to update the BIOS at all on this?
