So, I just received my iMac yesterday in the mail. I have the i7 3.4GHz/8GB/1TB/680MX variation. I love the machine so far. It's my first iMac. I have a MacBook Pro, and I have since 2011... Anyway, this leads me to my question. The iMac (and MacBook) both lose wifi signals quite often. I'm assuming since it's happening to both, my router (D-Link DIR-655) doesn't agree with the computers. Could anyone offer any input on this? I've searched high and low and I can't seem to remedy the problem and it's driving me absolutely insane. I've tried reseting the router and our modem, several times. It seems to fix it for a little while but the problem always comes back. Thank you for taking the time to read this, and for offering any help!
