We recently moved and now only have Comcast. We use to have Verizon FIOS. Our Slingbox Solo worked good on FIOS, but we can't get it recognized by the Slingbox software. I have set port forwarding on the Comcast Arris TG862G/CT for port 5001 and have assigned a static IP for the Slingbox. I can "see" the Slingbox when I go into the router config, The PC is connected to the router via an Ethernet cable. Bad news might be the PC / laptop is running Windows XP. When we first got the Solo we used a PC with XP to configure it.
