For this type of network issues with your Slingbox SOLO, I recommend to have a look at this link;
If you already performed all the steps and the issue persisted, read the note "What to do if the troubleshooting above doesn't help" that you can find on that link too.
Thank you for the links but I had seen that already.
Amazon being brilliant as they are, sent me a replacement slingbox solo and as thought the culprit was the Power outlet (plug). I had read this over and over about customers complaining and getting answers from fellow users with the same problem to just buy a new power outlet. However because my unit was bough this year, I expected slingbox to send me a replacement as they seemed like a modern company. However seeing all of the chargeable support and difficulty in contacting you guys, I just got amazon to give me a full refund which they have done. Slingbox is a nice idea, but the support to it's customers isn't there and thats a problem when there a free legal apps out there now that provide you the same service.
