This card has small buffer size No. I experience these problems mostly while playing MP3 audio files which reside on an NFS file system. It is invariably the server that gets wedged.

But a few years ago -------------- Half the money, if the reports I've heard of EtherExpress cards retailing at $50 are reliable.
