Kernel: Linux 4.4.302-rt232-st63 #13972 SMP Tue Jun 24 06:00:23 +07 2025 armv7l
Previous: pulled builds and then JUN 12, 2025
Mode: Internet gateway, WIFI 5GHz AP, smartdns with DoH, iptables firewall, SshD
Status: Working with issues
Issues: Can't correctly start CTF module. Speed of internet connection is ~180 mbit/s download
Uptime: 33 mins

I have weak WAN performance. CTF module won't work correctly. I'm back to build May 17, 2025, that last version where CTF works good and start via GUI during device work. I'm attach logs for authors to fix problem. If I use newer builds than May 17 CTF usally start with problems or totally can't work. Earlier was hint about low NVRAM size. Currently is only 31 kb and CTF work on an old build.

Mode: Bridged Network Switch + WAP (5GHz1&5GHz2&2.4GHz), No firewall, Only passing through traffic
Status: Some issues
Issues/Errors: All 3 radios are MIMO, however MIMO options are missing (BCM43602 x3); Switch Config port mapping is incorrect (WAN1 LED is port 4 UI, LAN1 LED is port 3 UI, LAN2 LED is port 2 UI, LAN3 LED is port 1 UI, LAN4 is port WAN UI); Not able to select channel number for any 3 radios when set to 40mhz & 80mhz(5ghz); Changing & applying settings for WLAN results in a temporary lock-out of reaching the router (no response to ping on any ethernet ports, browser times out upon applying. WiFi works and is able to ping to and from wifi devices very unreliable.)

As always, the Quantenna chip has its own quirks. This is a closed source chipset
There is no way to install a channel.
But you can disable 5.0 GHz. @mpgalaxy hack "If you set the radio mode to station bridge and disable the network mode, the 5GHz device will turn off completely even after reboot."

If your router's light turns red, don't worry. Internet connection is ok.

Thank you BS and gurus!

Netgear R7000
version 61848 updated from 61745 via web

Issues/Errors:
Netgear R7000 version 61848 - random restarts. Couldn't go longer than 12-18 hours without a reboot. Two different R7000 models and two different power supplies. Every router reboots after several hours. I went back to version 61745 and the routers have been working for over 3 days and no reboots.
