Cheapest way to go wireless on my iBook G3/800.

Factual Questions

Panther is the OS.

We have a cable modem hooked to a router w/ 4 ports on it: tivo, ibm1, ibm2, mac1.

I want to take my mac wireless, but don’t care to make anything else wireless, what’s the best way to do this? would I need a wireless router, or is there something that plugs into the 4th port and just makes that one wireless? what sorta card does my mac need?

On slickdeals.net there are some wireless routers, one’s $10 and one’s $45. One’s a “g” and the other’s a “b.” What’s this all about?

I hear that the B is 10mbps, so I’d notice a slowdown from my wired ethernet connection which runs at an alleged 30, what’s the G? Will I notice it being slower?

Help. I’ve no idea what’s going on, but I want to use my iBook outside and am not rich.

You can replace your current router with a standard wireless router, they usually have 4 or so wired ports in addition to the wireless. G is faster than B, but B is probably way faster than your internet connection, so the only difference would be in the transfer of files within your home network.

Your Mac will need an AirPort card, though I don’t know what is available on your model. AirPort Extreme is their 802.11g, regular AirPort is 802.11b. Your iBook may not be compatible with AP Extreme, my PowerBook wasn’t.
