Is there any advantage to hooking up my 211 to ethernet? I have ethernet hooked up to my 722. But to hook up the 211, I would have to buy a switcher and two short ethernet cables. I do not have a telephone in my house and the 211 is not required to be hooked up, so are there any advantages to hooking up the 211? Circuit City has the linksys switcher on sale for $15. and two ethernet cables are $2 each plus shipping.
