i never had a issue like that on my Beige G3 AIO in OS 9.2.2 with the stock hardware or upgraded hardware. i ran it on 1.6meg DSL and a 15meg cable internet and it flew on the net using both the onboard 10 base t ethernet (in OS 9.x or OS X) and the belkin wireless G+ PCI card (worked in OS X only).
sounds like the OS is having issues or its the connection or network hardware they are using.
go into system folder/preferances and delete Internet Preferences, Open Transport Preferences folder, TCP/IP Preferences and anything having to do with the ethernet or internet should be reset, for extra measures after i delete preferences i always reboot the computer.
if that dont help try reinstalling the OS and if that dont help then there is a hardware issue or a extensions conflict somehow.
