I use Shaw as my ISP and a 2611XM as router. I have been getting slow speed on the internet.
I found that when I hook my laptop directly to the modem, the speed is awesome. I called shaw and they said it has to do something with cisco routers.
Here's the output from show int command

Here's the output from sh run INt fa 0/1

I tried using ip mroute-cache and the errors started increasing fast. I have upto 30megs download and 2 megs upload on my internet connection.
I have tried changing the cable between the router and the modem and also speed/duplex settings on the router.
Behind the router I have a linksys 24 port POE switch.
Any suggestions on this is greatly appreciated.
you should clarify with your ISP what speed/duplex/cable to use to connect to his device.
It looks like 100Mbps/half duplex might work in your case (you are receiving a lot of CRC errors on your input).
What kind of device is on the provider side?
Some 100Mbps hub (would explain why half duplex necessary)?
