I'm having same issue. I switched from Comcast to Verizon the other day and therefore, switched routers. I have not been able to connect to new router, my upside-down U on Slingbox is just pulsating, and whatever I try to do to reconfigure, I keep getting message "Sorry but my web browser and operating system or combo is not currently supported but I have all the latest Microsoft 10/Chrome etc. I've even tried on IE and Firefox but my IE won't open, keeps crashing, and Firefox Addin won't download as I get a "file corrupted" message. This is getting frustrating.
