I finally setup a wireless network at home. We have Knology Broadband
coming into the house via cable modem.
From the advice of a coworker, I went with the Linksys Wireless-G Broadband Router. It has been working well. The only problem has been Knology's modem, which tends to need rebooting about twice a week.
The '03 Dell with Windows XP is hooked up to the router. This way, hopefully, I'll be able to share the HP printer hooked up to the Dell, and use it with any of the other computers in the house.
My Apple eMac is on the wireless network, and everything has worked like a charm. The installation of the Airport Extreme Card was amazingly simple. I wasn't confident about a wireless network, but I'm blown away at how fast it operates, plus the signal strength I am experiencing. Very nice.
My next project will be to get the upstairs Windows machine onto the wireless network. Once I purchase the card, it will be interesting to note how the installation process goes in comparison to the eMac's installation.
