I recently noticed an interesting quirk on my ethernet 10 base T network. I have 3 G3's an 8500, 8100, 2 Gateways, router and a network printer on a LAN. File sharing works wonderfully between the G3's and the 8500 as does the Gateways between themselves. But when I log into the 8100 from any of the Mac's the 8100 throughput is degraded, it does not want to send data continuously (rather, it sputters) in either direction BUT when I log into any of the Macs FROM the 8100 data throughput is perfect at 300+k/sec. I deleted all the appletalk/share pref's, rebuilt the HD's desktop's and verified all my cables with a Pentascanner to 100Mhz etc etc... But the problem is not cured. My guess to the problem is that the other Mac's have 100base T network adapters and they have problems deciding on a speed in which to communicate to the 8100 but when the 8100 is in charge of the data transfer it decides the speed. I beleive the 8500 is only 10 base T so Im in a quandry on that one. If anybody has experienced this problem and has found a cure please let me know. In the meantime I will only transfer data to and from the 8100 using the 8100.
