Ever since I replaced my hub with an SMC (Barricade) router, the network connection to my Dell Dimension XPS 866Br (w/Win98 SE) simply stops working after some amount of time following reboot of the machine. This time can be anywhere from 10 minutes to a couple of days! After that, I can't see the other PC on the network or the Barricade, nor can I get out via the DSL modem (which is on the other side of the router). The other PC (Win98) can still get to the DSL, but can't see my PC. Rebooting the Dell makes the network work again, for a while.
One thing that's kind of odd is that when I try to view the Properties dialog for my Linksys LNE100TX ethernet card in Device Manager, it takes something like 10 seconds for it to come up. After viewing it for the first time after reboot, though, it comes up immediately. I don't imagine this is any different than before I put in the router, but I don't know.
I've got the latest drivers for the LNE100TX, and the latest firmware in the router. What else can I try?
