Keeping an eye on SmartDNS as prior version 6**** working ROM releases 61848, 63020, 63223 and 63355 would stop resolving at random intervals. Workaround is to restart the service every minute with a CRON job. */1 * * * * root service smartdns restart.

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!

Router/Version: Asus RT-N18U/Rev. A1
File/Kernel: DD-WRT v3.0-r63391 std (01/17/26)
Previous/Reset: 01/14/2026 - r63355/No
Mode/Status: Gateway/IPv6 is not working properly.

I'm not a tech-savvy person, please pardon my poor English.

Issues/Errors:
IPv6 using radvd
Configuration
Enable IPv6 : Enable
Type : DHCPv6 with Prefix Delegation
Prefix Length : 64
MTU : 1452
Router Advertisement Daemon (radvd) : Enable

I made the router firmware upgrade without reset.... My client(PC) was assigned with an IPv6 address initially, and thus the online IPv6 & IPv4 tests were passed. Then, after a router reboot..., my client wasn't getting an IPv6 address, meanwhile the router showed that it still got it's WAN IPv4 & IPv6 addresses. What gives? "Radvd daemon went dead." is my first impression, so I try to enable it again via IPv6 tab's "Save & Apply" button, hoping that the daemon would start executing again.... Well, I tried a few times with no luck.


Issues/Errors:
IPv6 using Dnsmasq IPv6 Settings
Configuration
Enable IPv6 : Enable
Type : DHCPv6 with Prefix Delegation
Prefix Length : 64
MTU : 1452
DHCPv6 Server Daemon : Enable
Dnsmasq IPv6 Settings
IPv6 Router Advertisement (RA) : Enable

After enabled the above setting, and clicked "Save & Apply" buttons, waited a few seconds later, my client(PC) got it's IPv6 address. And, the online IPv6 & IPv4 tests were passed. On the other hand, a router reboot would still cause my client failed to get it's IPv6 address. Again, I put my hope via IPv6 tab's "Save & Apply" button.... It went well this time, my client got it's IPv6 address after a few seconds later!? So, I reproduced the whole scenario again for a few times just want to be sure. And, at the end of every time, IPv6 just ends up working.
