Note that I checked both remote and local servers. Local systems are on a
hub. Remote servers are reached via an ISDN router, a ACC Congo Voice/data
router, that performs NAT and dhcp server.
I notice this most clearly on my laptop but I believe I may have seen symtoms
of this on other servers.
The laptop is a PII 266, Enpower ENP-802 (Chicony OEM).
