Hey Guys -
I've got a Linksys WRT1900ACS router currently running the latest DavidV502 snapshot using kernel 4.14.91 which I updated to today. I have a unique issue which I believe existed prior to the upgrade which I wanted to post about.
I obviously have 2 wireless interfaces - 2.4Ghz & 5Ghz. Devices can connect to both and DHCP assigns correct IPs to both - however - devices connected to the 2.4Ghz interface do not have internet.
Long story, short; my router which hosts DNS for my LAN has the IP 192.168.0.1. When a PC is connected via ethernet or 5Ghz, I have no issues. Devices connected via 2.4Ghz do not get DNS, though. I connected a PC to 2.4Ghz and was able to ping WAN IPs, but not WAN hosts. Although DHCP gave it 192.168.0.1 for DNS, I statically set it as such in Windows and was still unable to ping WAN hosts. If I set the adapter's DNS to something like 8.8.8.8, it works flawlessly.
I do use dnscrypt-proxy in my router so am wondering if it is somehow involved. I still don't know how it would just affect 2.4Ghz, but have restarted a couple of times and verified all settings.
Any suggestions? Thanks!
UPDATE
I've been digging through configs and verified that dnscrypt-proxy seems to be configured correctly. Below is my wireless config. Formatting looks a bit off, but as you can see, both interfaces are pointed to the correct network: (I changed some values like the MAC addresses)
config wifi-device 'radio0'
option type 'mac80211'
option hwmode '11a'
option path 'soc/soc:pcie/pci0000:00/0000:00:01.0/0000:01:00.0'

option legacy_rates '1'
option htmode 'VHT20'
option txpower '23'
option channel '161'
