The only reason I choose AirPlayer is because it says "AirPlayer could connect to Win7 directly", means no need to install any software on PC. And indeed it could, with the instruction here, it's very easy to use my iPad autodect my Win 7 PC. But that only works when my PC connect with Route via wifi. If I connect my PC with Route via line/cable, the "autodect" can't find it.
The reason I would like to use line/cable instead of wifi is because I have 2 PC, one for download, one for HTPC use. So I need to copy data between 2 PC frequently. And the copy speed when both PC connect Route with line/cable (30~40MB/s) is 10 times faster than the way with wifi (3~4 MB/s).
I just went through all the topics in the forum but it's strange that no one have ever rise this issue before, does that issue only happen to me? or everyone else don't consider that's an issue?
