I understand the issue that you are having to stay connected to the Slingbox. I recommend you to test a different computer, just to confirm that the issue is not being caused by the Slingbox itself. If this only happens on the new computer; try to download a different browser like Firefox or Internet Explorer. You also can try to reset the plugin on the browser, have a look at the steps here:
Hope this helps.
Thanks for your imput.
Sreaming stops after about 5 minutes.
My box is in Luxembourg.
Here in Usa I stay 5 months.
I use here ipad. old laptop, and a new one (only for use to slingplay to TV.
All 3 worked fine with slingplayer till I had mmodem replaced in Luxembourg because of modem failure.
Then streaming problem started.
I contacted slingmedia by phone. have case number 00543520
My computer contact in Luxembourg has been working with stingmedia specialist Wolfgang in Europe to solve problem.
