I've got four Rio units in my house (2 Dell, 1 SonicBlue original, 1 SonicBlue "over" Dell). All connected to IBM ThinkCentre / Win XP / Linksys router/AP and 5 port switches. Also Linksys HPNA converter for one unit in lieu of Ethernet. All were working fine when one of the Dell units mysteriously stopped working. I can only get as far as the "IP-Subnet Mask-Gateway" banner screen and it hangs. It's allocated an IP by my Linksys router's DHCP but then cannot "punch through" (I'm not technical) to the server. Same problem whether connected to HPNA or Ethernet. Only cause I can determine is failed chip perhaps... Any help would be greatly appreciated!
