I do apologize that you have been experiencing issues without the Slingbox 500 remote. It can be a little tricky, but there is definitely a way around this! Your Slingbox 500 will need an Ethernet connection in order to get around this issue without the remote. The links below provide the information you need. Please let me know if you have any questions or concerns!

I have a slingbox 500 and I changed routers (new passwords, names, etc) and I've lost my remote. Any ideas on how I can connect my slingbox without a remote wirelessly? I really don't want to run a bunch of Ethernet and I can't find a replacement remote for sale anywhere. Help, please.
