Since purchasing this new MacBook, I have had the problem of my Wi-Fi intermittently not working. I will have a strong signal, be in the middle of working, and suddenly the page will not load, or I get the spinning beachball. I thought (and hoped) that when the new OS X (El Capitan) came out, the problem would be solved. It hasn't been.
I've figured out that if I turn Wi-Fi off, then immediately back on and then just reload the page, it will work fine. But that is just a band-aid; I want to get to the root of why this is happening. I know it is not an internet/network issue on my end as I just upgraded to a brand new router and modem, and upgraded to the fastest cable internet available. It only happens on the MacBook. Not the iPhone, not the iPads/iPods, not the printer.
I have run the diagnostics and taken a sample of all the times it happens to see if there is a common denominator, but there isn't. My network provider suggested moving the router closer to where I typically work so it need not go through too many walls, but it hasn't impacted the issue at all.
The only thing that has changed is that I have used the MacBook, adding applications, bookmarks, documents, etc. This was not an issue when I first got the laptop. It started about a month in.
In researching the issue, it is clear a lot of Mac users are having the same problem, but no "fix" that I have come across (and I have tried them all) has worked.
Any lifeline to fixing this will be much appreciated!
