Also does it specifically have to be a slinglink or can you use a third party homeplug set. Currently I have a dual netgear HD 200mbs homeplugs - one wireed to my 622 and the other wired to the router. Will this same setup work?
Other question is if the above does not work do the installers carry the slinglnks - the CSRs ask about whether you have broadband but do not state specifically that the 922 needs to be in the same room as the router of that you would need a slinglink (or homeplug). Seems like that would be important info for them to offer otherwise installers may encounter a number of people that are looking to place their 922 in rooms apart from the router. Having slinglinks with them would help counter that issue.
