Mac OS X 10.8.3, RMBP.
I have an all-in-one wireless modem-router, which has several Ethernet ports on the back. In wireless mode, which is what my computer is now set up to use, downloads have been exasperatingly slow.
To remedy this, can I switch, temporarily, from wireless to Ethernet connectivity, and if so, what must I do? Just plug the cable into the modem and computer via its Ethernet-Thunderbolt adapter? Or?
