For quite a few years I have been running 3 M5 units in my house alongside my Rogers router.  In the last week the M5 network is not connecting to the internet via it's wired connection to the Roger's router.  If I run the speed test on the Deco app, all seems fine, but not able to load pages in safari, and the Speedtest app fails.  Ping seem to take very long or fails. Wondering if there is a DNS problem.  Any ideas?
