If you’re an OS lion user, you may care to use its hidden WiFi diagnostic App, proving that yes, your internet provider is probably exaggerating its claims about performance. According to MacWorld, there’s no danger of messing up your system either.
When you find and launch it, Wi-Fi Diagnostics gives you four options: Monitor Performance (which shows you signal strength, noise level, transmit power, and data rate); Record Events (which can keep a log of network happenings); Capture Raw Frames (which records everything coming and going on your Mac’s wireless connection); and Turn on Debug Logs.
Easy with the slings and arrows there, Chrome Massive. This is a nice thing for MacOS users.
