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!

Hi Alozaros,

Were you able to get a workaround to prevent VPN leaks at startup? You are correct it definitely can be an issue, in my case it is a safety issue if any leaks at all.

Thank you,
SSP

Issues/Errors: Site Survey MACs are truncated

Thanks BS, egc, and others who create, improve, monitor, and report.

The "Site Survey MAC addresses are truncated by one digit" issue still remains.

This issue is unchanged from previous release(s), see for example my post on this topic here:

https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=338900

Specifically, in the Site Survey the MAC addresses displayed are truncated by one digit, i.e., they're missing the last digit of the MAC.

I've found this mis-behavior occurs in the Mar24 build r60467 and AFAIK all builds thereafter.

Builds prior to r60467 do NOT have this issue.

I noticed that issuing '/sbin/service site_survey main' on the command line returns truncated mac addresses as well, FWIW.

[egc]

A comparable rule should already be installed by the firewall see:
https://svn.dd-wrt.com/browser/src/router/services/networking/generic/firewall.c#L2720

So not sure what is going on but the boot up is rather complex and convoluted with multiple restarts

I use WireGuard and do not have any apparent leak
