Chapter in this post:
My reader Monika emailed me a while ago because her MacBook Air from 2015 keeps losing the WiFi connection. The usual approaches like Start in recovery mode, Start in safe mode and also SMC reset have already been tried. Here is your question in detail:
Hello sir, my Mac Air 2015 keeps losing the internet, tried several handles and the Apple help was there too. Are there still a few shortcut keys? So far it was always done with deleting the WLAN and resetting [...].
My Mac from 2016 is the finest thing I've ever come across from Apple. I had the keyboard done by Apple, everything was so great. I'm in love with him. No internet or wifi problems. Incidentally, all Apple devices are in one room. I need the 2015 Mac for the rough.
Of course, regularly deleting the WLAN settings cannot be the solution. The fact that the other Mac has no problems with the WiFi connection initially led me on the wrong track, because I thought it must be the 2015 MacBook Air.
In fact, there is a cause for the problem with the Internet connection that I would not have thought of if a reader had not told me about it in another post. The other post is actually about Solution approaches for Bluetooth problems, but his tip actually helped with the WiFi problems here as well.
The cause of disconnections on Macs is often related to the fact that there are incompatibilities between the transmission standards of the router and the Mac. In this case it was due to the 2,4 GHz wireless network that somehow couldn't work properly with the Mac.
Perhaps it was only possible when the router was comfortable switching to 5 GHz. As soon as it reached the 2,4 GHz frequency band, however, the problems were triggered.
My proposed solution of checking the router to see whether the frequency band can be set to 2,4 GHz or 5 GHz ultimately led to success. Monika completely deactivated the 2,4 GHz band and the WLAN interruptions were fixed:
Dear Sir Jens, I'm Monika again, with my Apple fetishism.
Your suggestion was great, I switched off the 2,4 GHz in the speed port and immediately had no more WiFi loss on my Mac Air 2015.
Unfortunately (or fortunately) I don't have a speed port in use with me, but in my Fritz! Box you can find the option to deactivate the wireless networks under Fritz! Box-Admin> WLAN> Radio network> Active frequency bands. Here is the appropriate screenshot:
