This is completely off topic but I bet someone here can be of more help than our Charter cable company. We received a call from some guy saying he was James from Charter and that we were due for a free upgrade from 5mb to 10mb on our internet speed. And all I had to do was disconnect my modem for 30 seconds and it would be up and running. I thought it sounded fishy so I called tech support at Charter who knew nothing about some guy calling people at home with free upgrades. AND he said we were on 5mb but we could upgrade free for a year. I told him I'd think about it. So this morning I got online with a Charter rep and HE says we ARE on 10mb right now! How can I do a speed test on my Imac?? I use Airport Express for my wireless.
