I don't know if this is related or not but the onboard Ethernet on my 7200 is horrible. Netscape will download a file at 1K/sec or even slower. I tried the ethernet port and the AAUI port and they both do it. This is connected to a 24 port NETGEAR 10/100 switch. When I put in a Realtek 8319 10/100 PCI card and used it instead, Netscape downloads at about 100K/sec.

My 7300 never had these kinds of problems; the onboard Ethernet was great. My friend's Beige G3 also performed acceptable with the onboard; he uses an Ethernet card though since he wants the most speed.
