I have Verizon FIOS as my web provider. I have a small LAN with two PC's connected to the Verizon supplied router. My PC, a home built AMD 2.25 Ghz Quad core runs just fine on non-web related programs. But periodically, the PC forgets where it placed the electronic LAN connection and I must reboot the beast. The other PC does not have this idiosyncrasy. What is happening?
