I hooked up my Slingbox 500 and was thrilled for a while. It worked great once I learned how to turn off the inactivity timer on the cable box. But now it won't play (not immediately after this change but close). The audio is spotty then stops. It's hooked up using an Ethernet cable and should be fine. I'm usually getting LTE or good wifi. Same as before when it worked. On my iPhone, it says 598 kbps in the lower left corner under tools. Is that an issue? The cable box and slingbox have been restarted. Does anyone have an idea for me? Help is appreciated.
