I have a solo and my power supply adapter was bad. As soon as I changed it the Network light stopped blinking and stayed red. I uses sling for about 5 years on the same router. I can't connect thru the Internet but I can use in on my home computer that the solo is attached to. When I do the setuo it can't see the router. I looked under gaming and Sling is there and port 5001 is there and 220.127.116.11 os there. I changed cables and did a reset as per instuctions. There is a Block Anonymous Internet requests and there are 2 choices enable or disable. . Not sure where to set it to. It's hard because the computer I use is at work and the sling is home. I don't know how to test it at home over the Internet. I can not connect from work and I know thru the set up that the device can't see the wireless routher. Which is the same router used for years. I am confused as to solve the delimea.
This could be an issue with the remote viewing, you need to make sure that is enable from the Slingbox location, you can check the following link to know about the Internet Viewing.
Besides that, if you would like to change anything from the router (such as the restrictions) I would recommend to contact the router manufacturer to do it.
