Though this is more suited for a Networking forum, it is appropriate for PowerBook users.
I updated to 10.2.5 two days ago and have found dramatic improvement in PPP dail up connectivity on my PowerBook. With 10.2.4, I either could not make a connection to my Earthlink account or the connection would drop after a few moments. Before 10.2.4, I could stay connected for hours.
With 10.2.5, the stable connectivity is back!
Why do I need dailup for hours at at time? I travel alot and can only connect to corporate resources using VPN under Virtual PC. So, the combination of the slower connection and the emulated OS can make what I do take longer than necessary without native Mac OS X applications. Speaking of which, are there such version for SecuRemote and Citrix? Or better yet, has anyone found a way to use SecuRemote via AirPort?
