Hey All
I have a cable modem with my 2600 Router and i have a little speed problem when im going out to the web via my F0/0.. according to regular speed test sites my speed is around 20mbps but when i hook up to my modem directly i get a solid 40mbps.. now ive changed my Cat 6 cable from my modem to my router and this are my settings in the router
interface FastEthernet0/0
description Modem
ip address 192.168.0.2 255.255.255.0
ip nat outside
ip virtual-reassembly
speed 100

I see some drops and lost carriers but not sure what those might mean.. ideas?

Errrr ... With CEF enabled, the 2600 router (if memory serves me correct) can process up to 18 mbps of data. The value is expressed in HALF duplex and no encryption.
So, if you have a 40 mbps cable modem ...

Did you measure the speed at different times to get a reading from router and modem?
