Vera 3 UI5, working fine, no change on network. I can control everything on the LAN but not remote. Vera Ui telling me it has no internet.

test shows this…

More details on your network topology are needed to make an educated guess as to the issue.

Since it seems to be getting to your gateway and it can get to the DNS server at 4.2.2.2 it looks like it has a connection. However, it seems to have issues resolving eg google.com indicating a possible DNS issue.

Are you familiar enough with SSH and Unix shell to SSH into Vera and do a DNS flush? I’m not able to access my Vera right now but below link shows the various ways of doing this under Unix. Which OpenWRT is a flavor of. I’m betting it’ll be the dnsmasq way…

reset the network setting to default and let things pick up again and it solves the problem.

I have Vera on DHCP reservation so it just reassigned the same address.

Must be a DNS issue as you mention.

I did some research and OpenWRT indeed does use DNSMasq to cache DNS entries. It sounds like that cache got corrupted.

SSH’ding into Vera,entering service dnsmasq restart at the command line and hitting ENTER should resolve the issue as well.

good to know… I also have my own DNS server. I just added that and 8.8.8.8 this should fix it. I don’t know why I only had the opendns in there to start with.
