That's an 802.11b router, which does not provide as fast a connection as an 802.11g router. It will work though.
However, I'm not in the US, but that looks bloody expensive. I would have thought that you could pick something up a lot cheaper than that which is 802.11g
EDIT: For instance, newegg have a WRT54G for $59.99 ($49.99 after mail-in rebate; just out of interest, does everything bought online for the US have a mail-in rebate? It's something that doesn't happen much over here). See here

2nd EDIT: Arse! I'm sorry that I didn't read your username. No doubt you can find something similar from a Canadian retailer although
www.sealflipperpierouters.ca seems to be down just now!
