I always use MenuMeters which is a great plugin that will allow you to see your network activity, cpu usage and so forth. I don’t know if my wife would find is so useful though, so it isn’t installed on her MacBook Pro (Amazon Affiliate Link) as it is on all of my machines.
Anyways, we just signed up for a new Verizon FIOS account and got the new Actiontech router to go with it. She’s the only one of us lucky enough to really take advantage of the new 802.11n features built-in though and I wanted to see if it was actually working. I was suprised that the Mac doesn’t show you the speed of your airport connection anywhere, so I had to search and found this great tip to just push the option button while clicking on the airport menu icon.
I hope you will find this useful as I do.
