If you reflash the box you might resolve your problems in one go, did you try to reflash it? I would flash with the latest Gemini image and hope that it will sort it out. At least with a reflash you will have done all that you can and if, after you have, the problem is still there then you may have to reckon that there is some fault in the box, this would be quite uncommon though. Hope a reflash will do the job for you.
Personally I prefer E2, though I have nothing bad to say about E1, after all I still have to use it on my 500s.
