I have a ISR 891 (no-wifi) router that I have been using on a 20Mbps x 20Mbps fiber circuit. It was been performing just fine. I am upgrading the curcuit to 50Mbps x 50Mbps soon, and I wanted to check if this router can handle that much load.
I don't do anything fancy with the router, just plain old routing (I have a firewall behind it).
Do you think the 891 can handle 50Mbps up/down, and if not what would you recommend for this new setup of 50x50Mbps.
2921 would be sufficient.
Not to necessarily disagree with Leo or what Cisco says, but before shelling out the money for a new router, try the 891 on the new circuit. You might be surprised.
