RX errors on Boost

Helllo!

I'm connecting my Boost (Boost2.0-85ea )to the home router (NH20T) with a Cat 6 patch cable and getting a 2500Mbps connection speed. I am experiencing intermittent slow wifi speeds - 120-150 down from a few test devices. 

looking at the router, I see 600 rx errors on the port. I power cycled both devices and the router reset, but already starting to see rx errors.I have replaced the ethernet cable already. 

Are the rx errors normal? I'm looking to eliminate that as a source of the problem.

thank you!
