What does 'Limited Access' mean?

I have a Windows Seven PC and a Windows Seven Acer laptop. They are both hooked up to a TRENDnet wifi adapter. It was working perfectly before! Nothing wrong with it, we had internet and everything was fine. Now, I opened up my laptop and it said 'channelnamehere' Limited Access. I believe I'm using just internet on my PC which I am using to type this but it doesn't really say... My adapter says Power Status WAN WLAN 1 2 3. All the things but 1 and 2 have little green lights like always. I have my laptop right in front of me now and it says I have a full internet connection too. Can someone please help me? Thanks.
