For Older Slingboxes The Magic Number is 237

I discovered this fix for my Slingbox after many attempts to decipher the often disparate advice available and giving up on many attempts. I can’t guarantee this is going to work for you as I only have the one use case to prove but if you have an older Slingbox this just may be the solution to your connection problems.

The problem was that I could only get the Slingbox to run once after doing a complete reset of the system and reconfiguring it. After logging out, the Sling box was again unable to connect. There are lots of explanations of this problem but after trying most of them, I can tell you that there is really only two things you need to know. First, is that the default local IP address for your Slingbox (if it’s not working correctly) is probably 192.168.[your router channel].237. Second is that when you configure your Slingbox online it usually assigns it to 192.168.[your router channel] .254. The result is that networking will fail when it tries to reconnect because of the wrong IP address.

How To Fix It

  1. Reset your Slingbox by pressing the tiny reset button on the back of your box.
  2. Set your Router firewall to allow a virtual TCP/UDP server on port 5001 of IP 192.168.[your router channel].237
  3. Configure the router DMZ for the same as step 2
  4. Configure your Sling box as normal at
  5. Click on the “Internet Viewing…” button and on the right side of the form, manually change the IP address to 192.168.[your router channel].237
  6. Finish the setup.

That should do it. Your Slingbox should work as it is supposed to now. Please post any questions to the comments and I’ll try to help if I can.

PS: Don’t bother trying to configure the Slingbox to use IP 192.168.[X].254. I did this and was the reason it took me so long to figure out that it would not work. The older Slingboxes just seem to require the 192.168.[X].237 IP address.

  1. I bought this deivce for my father as he is somewhat technically challenged. He kept telling me that he wanted to watch Netflix on his 52 LCD television. He was under the impression that he had to buy a Blue Ray player to achieve a high quality streaming experience. I figured it would be nice to buy a Blue Ray player since he’d have the player for all the DVD’s he owns and the Netflix streaming would be gravy. After pricing the BR players I realized that if I wanted WIFI built in, I’d have to buy an off brand unit to be at a comfortable price point. Further research revealed the Roku XDS which is a fantastic piece of tech. It is extremely easy to set up. From the time you open the package to the moment you’re watching a movie streaming from Netflix is around 15 minutes. You could probably even do it faster, but I was tinkering with some of the other channels that Roku has to offer. Since WIFI connectivity was an extremely important feature, I quickly went to that screen in the setup sequence to make sure I had a good signal. Since my router is 10 feet from the Roku box my throughput is very high. I could have ran a cable to the ethernet connection but then we’re talking more wires. I hate wires!!! I put in my WEP password and the box promptly started updating the firmware. In order to link your Netflix account the Roku will show you an alphanumeric code. You just go to […]and input the code that appears on the screen. Within 15 seconds or so the Roku screen will advance and you are now fully integrated with Netflix. There is no need to do this again unless you reset the Roku back to factory settings. The same procedure is used for Pandora and other channels offered on the Roku. There are dozens of other channels that you can add to Roku. If you have an Amazon VOD account, it integrates just as easily as the Netflix account. Then you have the ability to add Hulu + as well but I don’t recommend that. The cost is $7.99/month as of this writing and since you still have to watch ads, I don’t see the value. Lastly, if you’re on the fence about which Roku to purchase (there are three) you should consider the top of the line model or the second tiered unit. Do not consider the cheapest model because it lacks WIFI and will not transmit in HD. I happen to own the new generation of Apple TV (nearly same size as Roku). The reason I have the Apple unit is because of how it tightly integrates with iTunes and the iPhone 4 which I have. I can easily recommend the Roku player to anyone who wants to add a nice piece of tech to their multi-media systems. Best of luck and thanks for reading my review.
