Cable broadband

Hi

Was hoping someone could give a bit of advice on which cisco router to use with a cable broadband connection (virgin media 20mb) please?

I have been looking at the 851 but been told thats its ADSL and not cable also the 877 which is ADSL. Just wondering if anyone has either on a cable connection?

Im working on the CCNA want to get one to use instead of a vigor 2910 think be good practice to setup.

Sorry for the guys in USA who might not no Virgin Media they are a cable broadband ISP here in the UK.

Thanks

None of them will let you plug the Virgin broadband cable wire directly into it. You need a cable modem which gives you ethernet still.

Model comparison here. I don't believe the DOCSIS one will work in the UK...

you could always leave the vigor in place and put a cisco device behind that and practice your NAT\PAT skills too.....

If you want to use a Cisco cable modem look into the uBR series. I dont know if they're still in production or not but they shouldnt be too hard to find. Here is a link to the product literature on Cisco's site. http://www.cisco.com/en/US/products/hw/cable/ps2221/products_data_sheet09186a008008877d.html

The issues is that all the cable modems from Cisco only do regular DOCSIS and not the European variant. I've never seen a Cisco router that supported EuroDOCSIS.

I just looked it up and the Vigor looks like a regular router. The WAN connection is a ethernet port.

Sorry guys yeah I have cable modem so wont need a modem.

My Virgin modem currently plugs into Vigor which handles my firewall, DHCP and NAT stuff. So was hoping just to replace the Vigor 2910 with a cisco 851 but still not sure which is the correct one?

thanks

Any of the ones on the page I linked up above that has "10/100 Mbps Fast Ethernet" in the WAN Interface column. It will tell you what the difference is between the various models since there are several that has an ethernet WAN interface.
