I've had my MacBook Pro for a few weeks and have had no problems with my wifi but all of a sudden the past couple of days the pages started loading slowly and now will not load at all. My diagnostics show no ISP, no internet. My other devices on wifi are working fine. I've run the diagnostics several times but it just tells me to re-start the router but I've done that several times and now see the router is not the problem. Any ideas, help needed and much appreciated.
