Hello,
I just got a DHP-502AV and I also needed and additional adapter but there seem to be none 500Mbps adapters available in the stores... so the guy at this store told me that I could pair a DHP-306 (which is a 200Mbps) adapter to the DHP-500AV in the mean time and for this individual connection that doesn't require the higher speed. I just want to make sure this is possible before I open the boxes... any information would be appreciated.
