Zac Hall received Apple’s official statement on the topic of their AirPort routers:
We’re discontinuing the Apple AirPort base station products. They will be available through Apple.com, Apple’s retail stores and Apple Authorized Resellers while supplies last.
I’m surprised they chose to exit this market, especially since integrating mesh Wi-Fi into their existing products could be such a huge feature. I’d love for my HomePods and Apple TVs to extend the internet automatically in and around my house. This would additionaly be a great incite to actually buy more HomePods and would allow people to have less clutter in their houses.
For the most compatibility, reliability, and performance when used with Apple devices, look for a Wi-Fi router that offers these features…
If you just have a regular-sized apartment, just get a good 802.11ac router from a reputable manufacturer, but if you need great coverage over a larger area, mesh Wi-Fi, such as Eero or their competitors, is the way to go. Personally, I wouldn’t ever get Google’s WiFi mesh solution — I simply wouldn’t trust them with so much of my data.
If you are however looking for a Time Capsule replacement, just additionally get a 2 or 4-bay QNAP NAS and configure the Time Machine backup feature on it. I have been using mine for years now and it has been flawless, better than Apple’s own product, which required me to reset my backups every few months, due to some sort of error.
