I just got an iBook after being a die-hard OS8.6 user; I am new to Remote Access, and frankly, found similar "hangs" (or PITAS = pain in the a----!!!)
So, I am back to dialing up from the internal modem with FreePPP; the download is free at www.rockstar.com,
and I RECCOMEND THIS TO EVERYONE, unless someone knows of something better, tried and true?
This utility is very reliable for dialing internet; watch as your connection will say "connected at 115200" (!!!)
Really, you should get it; then just change your TCP/IP to "FreePPP", and "Manually" (all you need to do is put in server / domain info, and you're set)
