For whatever reason the wifi on my IMac does not work. Apple support could not figure it out so my short term fix is to unplug the Cat 5 from the router and plug it directly from the wall into my computer. Unfortunately that means there is no wifi in the house when I am using the computer. Afraid what it will cost to take the IMac in for repair so wondering if there is a way that the Cat5 can come from the wall and plug into my computer and router at the same time. Not a techie so could use some help.
