We are experiencing periodic DNS failures on our network.
We are Xfinity customers, The SVG2482AC Surfboard modem is in bridge mode.
I have checked the power levels as recommended in another thread, all look ok.
We are using an ASUS Wifi router RT-AX3000 (switched back to older RTX56 for testing)
we have updated, reset, tested to no avail.
the failure appears as webpages suddenly will not refresh, and usually we receive a DNS response error. the failure resolves in 10-30 seconds. this happens to ALL phones and laptops at the same time, whether wired or Wifi.
I cannot find anything in the modem nor router logs to explain.
Traceroute results are inconclusive.
Here’s the QUESTION: will/can a modem in “Bridge Mode” interfere with DNS requests?
I have not reached out ComCast yet because , well, Comcast...
