Amiko Alien 2 Image Trouble

Hi guys i could do with a little help here as i have used hyperion 4.5 before on a different box and had no trouble but for some reason on this box the image is freezing only on the sky channels every 20 mins or so and for about 30-40 secs each time, it's like the internet is stopping it but i know it's not that causing the problem and as i said i have used this image before on a different amiko alien 2 and not had these issues. Now that said i then decided to try hdmu and the freezing is gone but now i'm missing most of the movie channels even on a full scan some of the movies work like sky premier but most dont i really don't know what to do any help will be really appreciated.
