On the System Control Center page there is a system information page on there is the radio number. If you had the old one you could see if it changed. I'm not giving them to the new year. Dec. 28th is it for me. I will get Exede at the sell price on the 29th if mine is not fixed. They changed out my radio too and i know they did cause the number changed, BUT it didn't fix anything. Oh I have had great speeds until today but other kind of errors like Web Acceleration errors. Well today they changed me back to an old software. Big mistake now everything is wrong. poor speeds and still Web Acceleration errors. I'm about to give up on HughesNet.
