Sat down calmly and quietly today, determined to get the tethering sorted. It wasn't easy the other day when we really had NO internet and I was kind of panicking - couldn't get it to work (easytether), kept getting Error 67, but this is what I did.
1) download it from the marketplace onto my Hero and run the program - it gives you step by step instructions.
2) at the same time, I went to
Download EasyTether drivers and downloaded the drivers to my computer, installed them, and rebooted
3) Made sure on my Hero I went to the Settings-Applications-Development and checked on the US Debugging
finished installation on my Hero, connected it to the computer, and in the icon on the system tray, clicked on the "connect using Android" and VOILA!
The speed wasn't bad at all actually - i was most impressed with how easily it ran. I don't know why I originally got the Error 67 messages, telling me I had the incorrect PCS Vision name or password incorrect, but perhaps my recent updating of profile and PRL fixed those?
Anyway - it's great stuff. THANK YOU TO EVERYONE who helped!!!!!! You guys ROCK
