  • Strange net problems with a Netgear FS608 switch

    This was weird and now that the switch is replaced I haven’t been able to duplicate it, but let me explain. There was a netgear fs608 (8 port unmanaged) switch plugged into a linksys router (model number not noted.) The cable was straight (although the fs608 has support for link through straight or crossover cables.)

However, I still cringed at USB network adapters….
