I am not saying it makes it right, I am just saying even 500 is way over and above most users usage.
I think that's a bit out of date, with the average house with 2 adults and 2.4 children, each person having multiple devices (laptop, tablet, phone) and various streaming boxes (TV; radio, Google TV, Amazon Fire TV etc).
I'm sure modern routers support over 4096 concurrent connections through the NAT firewall. 500 would be easily used up. This of course should NOT OCCUR in MODEM MODE as the SuperHub 3 should be ROUTING and not NATing which is where connection tracking is required.
I agree with Mr Saffron, its another manifestation of the Intel chip issues.
