Wireless old iMac via Linksys

inluminent: Wireless old iMac via Linksys

Ah ha. It was just a matter of trying some different keywords, and finally I have paydirt. This blog entry describes getting an old (no air-port, just ethernet) imac onto a wireless network the easy way.
After much misinformation, this suddenly makes sense. I will be returning the access point (which came well recommended but how it was going to help was always a mystery to me), and procuring one of these wireless bridges.
