I've got a newer Linksys 16-port 10/100 switch (purchased in the last 
year or so).  So far I've had pretty good luck with it.  I've got a 
VAXstation 4000/vlc and a PDP-11/73 connected to it, and if it can 
handle running DECnet/E through it, then it's pretty good in my book. 
It also has an *old* Asante Ethertalk to Localtalk converter box 
connected.  I think the 10/100 hub the switch replaced was a Linksys, 
and it wouldn't work right with DECnet/E, but then I replaced it when 
I realized how bad of performance I was getting transferring a few GB 
of data via 100Mbit, there was just plain something wrong with the 

I do like keeping an older 10Mbit hub around with a 10Base-2 port on 
it (even though I do own a 10Base-2 to 10Base-T converter box, as 
I've got a DECserver 90L+ and an Amiga 3000 that require 10Base-2.

I had a really nice 8-port 10/100 Netgear switch, but the ports 
quickly started dying.  Plus the 8-port 10/100 Linksys hub had some 
dead ports as I recall, and I had a 24-port Intel 10/100 switch with 
a lot of dead ports, that finally gave out on me.  All in all, I 
don't have a lot of faith in hubs or switches lasting very long.  So 
I'm personally inclined to attribute such problems to switches that 
are going bad, than Linksys switches not working well with older
