connecting wireless router backup to my macbook
I would like to backup my macbook to an external hard drive connected to my router (ARRIS SURFBOARD AC 1600 CABLE MODEM).
First, I am a techno-impaired senior so please be gentler.
Second, I have tried without success to find a link that would explain how to do this.
Third, I am sooo hoping this router/modem will let me do that to an Apple product. Any help would be greatly appreciated. Thanks!
MacBook Air, macOS 14.4
