I have had same sort of problem. The (same) adapter was bought to connect a Panasonic smart TV to internet. It has a blue light (5 GHz) when connected to HH2 via TV but an amber light (2.5 GHz) when connected to HH2 via my PC. I have too issues: firstly whether I use this adapter or a trusty old belkin "G", I get OK PC connection but BT diagnostics state that I have very weak wireless connection - with the adapter in same room. Yes, I have tried different channels - to no affect.
Secondly TV internet (despite good signal strength) keeps dropping out, making it unwatchable. If its connecting at 5GHz and HH2 cant handle that, how do I get any connection at all? If it would help, how do I get the adapter to pick up the HH2 at 2.5GHz?
I moved your post as the previous thread was 4yrs old and this is the correct board for your problem
