Hint: search for port 443 or SSL

I have yet to fail slinging. From any network. Not saying it's impossible to make the network ultra tight, but, I have yet to find that network. (I think the Cisco accelerators with certification "cache" - akin to a man in the middle attak - might beat me, but, I haven't had a chance to try my hand at that.)

You are kidding right?  You have not bothered it seems to read enough posts to understand how you may be able to get around corp firewalls..  Then you blame Sing for it!!    Do as the hawaiibee has suggested.  Call your IT guy and ask them to open a port.  Then get your resume ready because you will need a new job...   Use port 443....  My guess is it will work that port is used for secure HTTP (HTTPS) traffic and some Copr office leave that open.

Warning....  Warning.....  The sling box you have just purchased  may not work in all corporate offices.  You may not be able to waste your time watching TV while we are paying you to work....

I have read all the posts.  Tried all the suggested settings.  It says it connects and is streaming, but I get no video or audio.  I don't think it is unrerasonable to advise consumers that many networks are designed to prevent slinging.  But wait, that would affect sales and be truthful, we wouldn't want to have that I guess.

If it actually connects and is streaming make sure you have the input specified correctly in the slingplayer software.  if your input is wrong, you may be just streaming "no signal" which is why you have a blank screen.  If your using a laptop, can you stream successfully on your local home network with the same laptop as on the corp network?

  My personal laptop works fine at home on the LAN.  Haven't brought it to work to test, don't think my personal laptop will connect to office network.  My office PC is also a laptop.  When I take it home it doesn't see the Slingbox on the LAN. Where do I check the input on the slingplayer software? When i launch slingplayer at work it says, loading, 1 pending, starting stream (but no picture or audio).  I checked the properties and it says the configuration is loaded, if that means anything.

If it says "Starting Stream" and you see nothing, it is probably because your Video source is turned off...simply go to the remote and press the power button to turn it on.  You will only see a black screen until you power on your cable box/dvr or what ever video source you are connected to.

I disagree..  He should get the no signal message if that was the problem.  Also, it should go past starting stream to streaming..

I think it's a network isssue..

 

You're correct that it should go to "streaming"...but I never get a "no signal" message, just a black screen when my DVR is off and I'm connected to my Slingbox (until I power on the DVR).

Let's keep in mind that the Corporate environments are using in most cases more sofisticated routers and firewalls than the average user at home would use.  The basic fact is that if he is able to sling outside the home other than the office then it would be a network issues at the office as I'm sure we all know to be the case.  It may not be the port itself but another firewall layer within  the network. 

Puttting a warning on a box would not prevent most from buying it since it is returnable at most over the counter locations. 

Try it and it works you keep it.   

We all feel for you but there are just to many people out there using it and working fine.   You happen to be one of the unfortunate ones that have a tight office configured network. 

How do I start a new thread?

I think you all missed this comment from MitchG:

My office PC is also a laptop.  When I take it home it doesn't see the Slingbox on the LAN.

Before we get to that problem, How did you install and configure SlingPlayer on the office PC?  While you have it at home, try copying the entire Sling folder from your home PC to the office one.  It doesn't have to go into Program Files, so just to keep it with your personal stuff, create a My Programs folder under My Documents and put it there.  Then run slingplayer.exe from that location.

If that doesn't work, make sure you can access something else on your home network -- like shared documents on your home PC.  If you can't, check the network IP address.  Maybe it is not dynamic and the office configuration does not match you home network.

You didn't mention if you have accessed your Slingbox from any remote site.  Since your home laptop works at home, take it to a coffee shop with wifi access and try it there.  Once you get your office laptop working at your home, try it at the coffee shop.  If it works at home and at the coffee shop but fails at the office, then you are back to determining what is causing the blockage at the office.
