Hi, Ever since I got my MacBook Pro 13 inch retina early-2015 (it now runs macOS Sierra), the wifi has been bothering me. Sometimes, out of the blue I lose internet connection even though the wifi signal is showing a strong signal. Turning wifi off and then on again immediately resolves the issue. It could be my router, but all my other wifi devices function fine - so I'm not sure. Does anyone have any ideas? I would greatly appreciate your help. I tried using the search function but I don't seem to be able to find this exact issue (could be me ) Thanks.
