Swapping from XFinity XFi to CM2050V / RAX200 drops my speed tests from 400+ to 100 ish

Thanks, will do,

I ma getting a slower speed hardwired also only just above wireless speeds - not what I expected.

I checked the pings and tracert and see the response times to the Xfinity gateway and DNS is slow  (see piong and tracert stats below)

I will check with Xfinity as this is meant to be a gigabit connection.
