Re: [H/W] Home Setup - 50MB Cable Connection An 861 is able to push that but with no extra services enabled (firewall/IPS/crypto), just NAT and some ACL entries.
If you want more power look for a 1811/1812, they are super speedy for this job.
You'll also gonna need a 802.11n access point, a cheap D-Link/Linksys should do. No need to go Cisco for 11n home use.
