1720 as home router..

I've been using my Cisco 1720 as my home router for a couple of weeks, been working great. But, the speed isn't there compared to my POS network router with wireless. I did a speed test with my Cisco, got 6down 2up, sounds good, right? Well, that was until I plugged in my netgear again, 10down 6up!

Is there something in my configuration that could be causing the slowness?

hard to say without your configuration.

it also could be that your modem resynced while you changed the routers and got a "better line"

Maybe no ip cef? Not sure why it would cause a slowdown though.

Looks like you are about pegging the little thing out as far as bandwidth. Remember, these things were designed for the days of a T-1 being the common pipe size for a small business.

I think you're right. It's an old router - plus the link from the router to the cable modem is only a 10mb.

from memory an 1801 can get 30Mbps

according to http://www.cisco.com/web/partners/downloads/765/tools/quickreference/routerperformance.pdf
what you are getting 6Mbps is spot on for a 1720

Why is Ethernet0 half-duplex?

If I set it to full then I lose all connectivity.
