Had Verizon DSL and then had FIOS installed one week ago. I have the Verizon MI424WR router with one PC wired to router and a second PC using a wireless card. Also have TIVO and Wii connected by wireless to internet through router. I can access the internet using all the connected devices. I have gone through the steps to create a "home network." However, although the network shows up on each PC, the two PC's can not see each other and the TIVO can not see the main computer to play music files or view photos. I also can not print to the printer connected to the hardwired PC from the wireless PC. I have checked that file sharing is enabled. In the router setup, I can see that the router sees all the devices. Is there a firewall setting in the router or something else that is preventing each device from seeing the other? All this worked perfectly with the DSL and my home network. Thanks for any assistance.
