Getting an old iMac some wireless networking?

Hello. I've got an old G3 slot-loading iMac that, unfortunately, doesn't have a slot for an AirPort card.

That means I have to go with either a wireless Ethernet router, or one of those wireless USB things.

I've looked around for both, but I can't seem to find them in stores, and before I buy one online, I'd like to make sure that's my only option.

I don't want to buy an AirPort base station because that would be overkill. I just need that iMac to be able to access the internet wirelessly.

I'm not looking for a full router, just one that connects to the Ethernet port to provide wireless internet to a single computer. I remember seeing a small cube thing that D-Link sells that's just a small box with one Ethernet port....

Or even one of those USB adapter things. Preferably, I'd like one with 802.11n because I'm going to buy an AirPort for a different setup (it has to be on a different floor than the iMac), and don't want a 802.11g adapter to slow the whole network down.

Any suggestions?
I'm in Toronto, Canada so if you even know of a good store, that would be great too!

 

Thanks for the reply. Yeah, ethernet based does sound best. Especially since the iMac only has 2 USB ports, one already being used up by the keyboard.

So am I looking for something with the acronym "WET54"? What does that stand for?

I remember buying, and later returning the next day, two routers that didn't work. The guy told me it was what I needed, but maybe I explained wrong, or he didn't really know, or it was somehow not entirely Mac compatible. But I doubt it was the last one.

Anyway, it probably wasn't the right kind of ethernet router (or whatever you call the ones that simply connect to a wireless network, and don't actually broadcast a signal).

I'm not tech-illiterate, on the contrary, actually. But this is one area I'm not totally familiar with. I learn very quickly though. And I did do some research a while ago and found a Linksys model (probably the one you suggested) to be what I'm looking for. However, I just want to be sure.
