I worked tech support at an ISP and despaired when someone with a Packard-Bell called in. First, they'd let you know it, as though they were telling you they had a high-end Real Computer. Second, you instantly knew it'd have a cheap POS LT Winmodem that would only train up to 28.8 if the wind was blowing in the right direction, and would buffer underrun if the user tried playing an MP3 while they were downloading something.
Ugh, I despised dealing with that gear.
Those shitty modems were infamous. IIRC they were also the sound card on the box and had serious issues with interrupt conflicts. It took three wizards and a dead chicken to get Doom to run stably in an online deathmatch.
