Ethernet slow to initialize on startup
Lately, on startup, my mac won't connect to the network. It's wired in though ethernet but for some reason it takes a long time for the internet to initialize; sometimes minutes. No issues once connection is established and AHT hasn't revealed any internal hardware problems. The specs for my machine are below. I'm using an arris modem and an Airport Extreme. Not sure if the issue lies with the router and don't know how to test that. The delay seems to be increasing over time. Advice?
