Ultrageeky

Let's not spoil things by getting ultrageeky, Mr. G., but I need to get a tad technical for a graph or two to explain why you are among the millions of Americans with spanking new cable modems who are prime candidates for Intel Corp.'s superb home wireless-networking system.

They present cool ideas at semiformal gatherings like Code Con, an ultrageeky show-and-tell held at San Francisco's DNA Lounge last month.

If, on the other hand, the problem persists, you know you've got some sort of system-level problem, and it may be time to call in the experts (Apple Support, your favorite troubleshooting Web site, or an ultrageeky friend).
