I started having this same problem about 3 days ago.
My Slingbox Classic was working fine one day and then kept dropping the network the next day. Nothing has changed on my network.
I tried resetting to factory defaults and now I cannot complete the initial setup. When I reboot the slingbox the network light comes on after about 20 seconds. I can ping the box from my PC. The Sling Client sees the box and starts the Setup Assistant but as soon as it tries to configure the box the network light goes out and the setup assistant halts and says "The connection to your Slingbox has been lost. Please make sure your Slingbox is on and connected to the network. Click Close and then relaunch the Setup Assistant." I've tried this several times now with the exact same results.
Here are the properties from my slingbox that I am able to see from the slingbox properties dialog box in the slingplayer:
Hardware version: 1.0.2
IR Blaster version: 2
Firmware version: 1.2.16
Firmware release date: 02/04/2009
Let me know if you need any other info.
Please help as I use my slingbox almost everyday and have had no problems for years until now.
I have my Slingbox a state away at my parents' house, broadcasting local cable to my apartment and was only home for one day to address this issue. I had zero luck and, since I'm not there, cannot confirm the details of regarding my firmware, etc. At least I know now that this is an issue that affects more than just me.
I'm not sure it is a power supply issue because I am able to ping my slingbox from my PC all day long without dropping a single packet. However, as soon as I try to access it from the slingplayer that is when it drops. It actually looks like the box is rebooting when the slingplayer tries to access it because the network light goes off and then after about 20-30 seconds it blinks a few times, then stays on and then I can ping it again. I've tried several different versions of the slingplayer from 2.04 to 2.03 all the way to 1.5 and all of them cause the box to reboot when they try to access it. I've even tried to use the web setup assistant and get the same results.
I've isolated the slingbox on a D-Link switch with only my PC attached and no other cables plugged into the slingbox and it still behaves the same way.
Is there anyway to do diagnostics or turn on debugging to see what is causing the box to reboot whenever it's being accessed?
What are the chances of getting a replacement or refurbished box from slingmedia?
I had the same problem and a new power supply indeed fixed the issue.
As this was the second one that went bad for me I went to Radio Shack and purchased their EnerCell multi voltage AC-to-DC Power adaptor. (6/7.5/9/12VDC 2.5A). Additionally you will need the power tip "M" (you get one free power tip). It is a bit more expensive but this Power supply runs alot cooler than the original ones. Time will tell if it will outlast the original ones.
I went to Radio Shack today and bought the Enercell AC-to-DC Power Adapter 3/4.5/6/7.5/9/12VDC 1000mA
and it is working. The 2.5A adapter was twice the cost ($41) so I wanted to try the 1A adapter ($21) and so far its working great.
Thank you so much for suggesting the Enercell adapter. You saved me the cost of buying a new slingbox. My wife was going to get me a new slingbox for Father's day but because I wanted the new iPhone 4 instead, I postponed getting a new slingbox. I'm glad I did. Thank you.
