Wireless Time Machine backups with non-Apple router
Apple hasn't updated Airport Extremes or Time Capsules in very a long time. Rumor has it that Apple is phasing out routers. My Time Capsule seems to be on its last legs, so I am considering buying a current generation non-Apple router. 100% of family internet use is through two MacBook Pros, neither of which is conveniently located near the Time Capsule or its planned replacement.
Previous "Discussions" questions found on this topic are many years old and say that Apple does not support wireless Time Machine. Has this changed? I know that today's external drives are small and able to contain lots of data. It would be easy to connect one of these drives to each MBP, but even easier if TM backups could be done wirelessly as has been possible since 2013 with Time Capsules.
Thank you for any help or suggestions!
