I recently purchased a new 13" retina MBP, but since then, my household has experienced disruptions with their computers maintaining a connection to the house's wifi network. Its almost as if my new computer is knocking them off the network. They can reconnect but must do so manually. Their computers are PC's running Windows 8. It's seems rendom, but definitely began after getting my new rMBP. My connection seems stable. At times I was downloading new software, but others I wasn't. Has anyone else experienced this or similar problem? Any suggestions to troubleshoot or correct it? Thanks very much.
