If you are planning on getting a laptop with a wireless network adapter and want the laptop to connect wirelessly, then you will want to get a wireless router.  Unless you plan on frequently transferring large files between computers there is not need to get a high speed router (Super G or Pre-N) as these will not speed up the internet connection since the speed will be limited by the cable connection.   You will see no speed degradation on your cable connection when using a router.  Wired or wireless routers from Linksys, D-Link, Netgear, and Belkin are often recommended on these forums.

Thanks for the prompt reply, Steve.

I had some concerns over security issues with a wireless router (needless?) and was thinking of the Linksys BEFSX41  seen here. It seems to be the only wired router offered that specifically mentions the word 'firewall'. What do you think- appropriate? Overkill?

All routers, by their nature, have a firewall.  Security is always a concern, but firewalls and encryption (built in to wireless routers, but need to be activated by the user) greatly  reduce the risk.

Much obliged, Steve.
