I have had this issue in the past and I ended up getting one of the slinglinks replaced. I'm thinking that's probably the problem but without paying the rip off fee of $30 yet AGAIN, I can't be for sure. Here's my problem:
Slinglink 1: All lights green
Slinglink 2: Power light green, network and link light flash
I've tried the same outlet trick, the reset trick and everything else recommended. These have worked in the past so I know it's nothing I'm doing wrong. I have this brand new $300 slingbox that i was to activate but it's going to be returned if I can't get these slinglinks working. I was told to activate the slingbox and then they would help me. I do that and then I can't return it. I just get so frustrated with money hungry customer support.
Anyone here have any thoughts?
