I recently setup a media center computer in our bedroom to go with the one we have in our living room. When I did, I found I was unable to stream HD recordings via the USB wireless N adapter I just purchased for it. I've checked all the obvious stuff - directly copying the file, I get 2.75mbytes/second (22mbps). Over wires, the file plays fine. Couldn't tell you the exact transfer speed (didnt check when it was wired) but typical network transfers are around 10-12 mbytes/sec from my HTPC and 7-10 mbytes/sec from my Dlink NAS. I have 2 laptops (mine/wife). Both have wireless N, both can play the files with no prob. Again, couldn't tell you a direct transfer speed, but definitely higher than 3megs/sec. I can check when I get home from work but I doubt it will matter. Its not the router. Router is set to N only. On the computer in question, windows shows 5 bars signal and a connection rate of 104mbps. USB 1.1 caps out at 12mbps, and its faster than that, so USB2 is definitely working. The wifi adapter is an ASUS (dont remember the model) USB N adapter I just bought on newegg. So basically, I've narrowed it down to the wifi adapter, but it says its getting a connection rate thats plenty fast, yet the transfers are slow. Any place I should start looking?
