Hi Karin Sandblom,
Thank you for posting to the Community. With the Slingbox 350, the network light being solid means that the Slingbox is receiving and IP address from the router, if it did not, the light would either blink or remain off.
How do you have the Slingbox connected to the router? With a direct connection from the Slingbox to the router or with a wireless bridge or powerline adapters?
When trying to connect to the Slingbox, is this at the Slingbox location or a remote location? What are the network speeds at both the home location and the remote location?
Awaiting your reply,
