here is the link for the $10 rebate
i just purchased the linksys Wireless G router this morning because of the thread above, i played around with my friends and i must say i am impressed with all the options. He bought it just last week and paid $130 for it. Boy hes not going to be happy after i tell him i got the router for $80 cheaper
info on the d-link info on the linksys
as you can see the difference is one is B and one is G. G is backward compatible with B. But G can reach up to 54 mbps with the right kind of card (you wont hit 54 but come close to it depending on interference and what card you are using. also side note the linksys is using a draft protocol for the G routers. )
linksys is awsome with their rebates.
