Where is recommendation for best used Cisco router
with switch for power home user? Chances are if you have WAN connection with less than 20MB/s and don't require LAN faster than 100mb, u can get very decent quality Cisco routers with advanced IOS features.
Of couse for those new Cisco guys/gals who might find it useful to have Cisco gear for other uses than lab. As long as you understand IOS and commands, u can configure a lot depending on firmware version.
And you don't necessarily need 2 NIC cards. You can run network on 1 NIC if you have managed switch that can run VLANs.
