hello all, so I have had a issue of late. It seems that my MacBook pro is crashing my network. I have a 2012 retina MBP, 2008? iMac, two iPhone 6, iPads, nest thermostat, Apple TV all being run off a newer model AirPort Extreme and a Motorola surfboard. I have a pretty decent internet plan and have never had a issue in the past. Lately, whenever my MBP is on the network, it will cause all other devices and the airport to lag. The Apple TV will stop streaming, my iMacs internet won't work. But the minute I turn off the wifi on the MBP, everything goes back to normal. I have been running the bitdefender to look for malware. It came up with none. I got a "network" monitor that said I was being attacked by a MiTM attack, but even after changing the name and password, it keeps saying the same thing and is still causing the network to severely lag. Any help?
