this is a docis 3.0 modem. its rated for 100 mbps and its around $40 so i would think it would work. just be aware that its not really future proofed (if you are to upgrade to something higher in the future.)

this is a really cheap router i found off of amazon with mostly good reviews. i dont know how well it works, but if you want, you can test your luck. its also wireless n, so it isn't that bad.

Cool in that case, I'll order

Are these good for speed? I work at home so fast connection is important. Is there a faster hardware that I should consider?

You mention that the installation guy will just come turn on the modem. Do we even need the guy to come if we buy our own stuff? Can I be the one that "turns it on"? Also, I am also ordering a home phone service and cable so he may need to come anyway?
