What does 'mii-diag' report?

No, this is a very uncommon problem.
The closest problem is DHCP failing due to autonegotiation delays, which
will have the effect of the network being unreachable.

Another problem -- very unlikely with a home network -- is that the
connection to a Cisco switch won't work for about a minute after
plugging in because of a discovery protocol.  Plugging in through an
always-on repeater avoids triggering the link-up-triggered discovery.
