I used to have Verizon DSL. I changed over to Time Warner. I though my upload speed was the reason that I was loosing my connection with my sling box. Right now I have Time Warner 30 mps Up and 5 mps Down. Now I tried after getting this newer high speed to connect to my sling box. I had the same results. Comes on for about 5 to 10 seconds and then it will not re-connect. I think now it is a Router/Modem issue. I just purchase a Motorola SURFboard SBG6580 Wireless Router/Modem.
I have tried several times to run through the setup. Have reset the Sling box device and have reset my modem. Now when I go through setup, I type in a new password, confirm it and then continue. It takes me 2 or 3 times to get through the setup, because I loose connection and I must start over again. If I get completely done with the setup, and I try to watch TV, to connect to my Slingbox, it asks me for a password. The password I just changed will not work. I have to try and configure again.
