RB153 + SR2 as simple AP

Does any have and with how many of clients works stabile.

It’s simple AP without pppoe, DHCP , etc…

I guess this would depend on the speeds you wanted.
If you could afford to, go to the rb500 series that way you will never look back.

with the smaller CPU I’d think you could still get 20+ without nstreame or very high simultaneous transfers.
however I am not talking from experience.

I have found tho that it’s Packect per second, not really number of associations that will bring an AP to it’s knee’s
