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!

Previous: original r63230 build
Mode: Internet Gateway, WIFI 5GHz AP, smartdns with DoH, iptables firewall, SshD
Status: Working with issues
Errors: Smartdns module working unstable. It provoke unexpected reboots, suddenly stop DNS translation operations. We can't open websides, using Steam client, update software installed on workstations
Uptime: difficult to type now, many reboots and Smartdns unstable

Smartdns unexpected stop working. When I use method smartdns restart -> file /etc/smartdns.conf is absent and can't simple restart module. When I make it via GUI device goes to reboot.
My version of Smartdns: 1.20260103-1315
Config of Smartdns:

On GUI:
- Dualstack IP selection -> Disable
- Prefetch Domain -> Enable
- Serve Expired -> Disable
- Use Additional Servers Only -> Enable

Additional config:
- server 8.8.8.8 -bootstrap-dns
- server-https https://dns.google/dns-query
- force-AAAA-SOA yes

My Smartdns config file content:

bind :53
prefetch-domain yes
log-size 32K
log-num 1
log-level warn
log-file /tmp/smartdns.log
dnsmasq-lease-file /tmp/dnsmasq.leases
ca-file /etc/ssl/certs/ca-certificates.crt
ca-path /etc/ssl/certs/
server 8.8.8.8 -bootstrap-dns
server-https https://dns.google/dns-query
force-AAAA-SOA yes

I. Why configuration is not stored in /etc/smartdns.conf ? You moved config file to /tmp/smartdns/smartdns.conf What is reason of this ?
II. Log file doesn't exist. Original location is /tmp/smartdns.log File is absent and why location isn't /tmp/smartdns/smartdns.log
III. When I'm config Smartdns in GUI and have options: Dualstack IP Selection Disable and Serve Expired Disable - Why that values not found in config file ?
In my opinion should be "dualstack-ip-selection no" "serve-expired no". And where that values in config file ?

Generally Smartdns is definitely unstable and provoke crash of this module and whole software.

Mode/Status: IPv6;Not working

After reverting back to r63230, and via https://www.test-ipv6.com/ testing, it's working again. Maybe the problem is related to my ISP side, but I reported it anyway, just to be on the sure side.

Netgear R7000P

Unbound didn't use my custom conf

Not sure what changed

Had to revert to previous build

[kernel-panic69]

The usb drive my unbound config was on got munched a while back on my R7800. What filesystem is yours formatted in, if not on internal flash jffs, and does everything else that needs the USB drive(s) working as it should? P.S. Logs and exact configs would help...

[itwontbewe]

my notes with more info are on a PC. I'm on a phone right now.

I use jffs2 and an adblocking script also stored there ran without issues
