The concern of my question is about router security via updates.
I used to have various Modem/Routers (eg. Belkin, TpLink, etc.) over the years to connect to my ISPs. All followed the same pattern: Manufacturer supported them well at the beginning, the devices were receiving regular updates, then some years later they were reaching end-of-life and there were no more updates.
Also, I want to change the way things are connected at home.
Instead of having every device connected directly to the Modem/Router, I want to have everything connected to a Router (To-be-purchased), and then have that Router bridged to the Modem provided by the ISP.
So the question is:
Could you please suggest any Router devices which receive regular long-term updates for many years? The longer the better.
(FYI I have looked into Mikrotik, OpenWrt but I don't know for how long they provide updates. Also, I wouldn't mind purchasing a business-oriented device if it suits my needs)
