After upgrading i get a user.err with the dnscrypt resolver and have lost internet connectivity.

-user.err : No resolver named [adguard-dns-ns2] found in the [/etc/dnscrypt/dnscrypt-resolvers.csv] list, unable to read file either and does not have an a config file.

-Unable to save specific options such as disabling dnsmasq and Recursive DNS Resolving (Unbound)

I'm not on this new release yet, but some general points: the last several releases have not had the "Encrypt DNS" button, so if you want DNSCrypt, you'll need an approach using Startup Commands like I described in a post (last one in signature below) in the new-build thread for 39144. (Others before me have discussed it also, in the context of using multiple DNSCrypt instances.)

In DNSMasq settings I enable DNSMasq of course, but the other buttons are optional, except I suspect (not sure) for "Recursive DNS Resolving (Unbound)". That option is used in the DNS-over-TLS approach (more involved than DNSCrypt to set up) discussed in Not sure whether it has other uses also. It may need to stay off to set up DNSCrypt.

Re adguard, the resolver list in my dd-wrt (39144) only includes four options, not including the one you mention:


I use the second one with no problem. Parameters from a newer resolver list you find online can be put on the dnscrypt-proxy command line in Startup Commands. (See my post that I mention above.)

Re file readability... ls -l /etc/dnscrypt/dnscrypt-resolvers.csv shows it not readable? If so, try copying it into /tmp in Startup Commands, marking it readable there, and referencing the copy from the dnscrypt-proxy line you'll use in Startup Commands. (Again see my post that I mention above.)

Good luck.

Five of the Linksys WRT1900ACSv2, on r39144 and r38159. On various: VLANs, client-mode travel router, two DNSCrypt DNS servers (incl Quad9), multiple VAPs, USB/NAS, OpenVPN client (random NordVPN server).

VLANs on the WRT1900ACSv2 and other two-CPU Linksys/Marvell routers:

This build fixed my WRT32x 2.4Ghz issues. My Nintendo 3DS now connects flawlessly and WPA2-AES is working too. I previously had to use WPA-AES as enabling WPA2 would crash the interface.

Just to inform you that I flashed my wrt3200acm (v2 I think) with the factory-to-ddwrt and for now, it's working fine (less than 1h ..).

My main issue was the scandalous Linksys stock firmware which constantly drop packets getting out through the WAN interface. I can't believe they are not fixing it, fortunately, I planned well before to switch to DD-WRT : it just pushed me to do it.

Thx for your work Smile

EDIT : flashed from Win10 and Chrome

I'm having packet drop at WAN output but it was the same as with Linksys stock firmware. I think I have a defect router, I will open a new topic.
