My PC (HP Media PC M7183C) came with the above adapter. My ISP is Comcast and I am paying for their Blast service which is supposed to give me at least 105 mbps.
Running a speed test I am getting download speeds in the low 70 mbps. I had a Comcast tech come to my home and he connected his laptop to my network and he was able to achieve speeds well in excess of the 105 mbps. His indication to me is that perhaps my network card is not functioning correctly or the settings for the card need to be changed. The driver version I am running is 8.0.47.0 which is dated 12/6/07.
Are there actually settings that could be changed for this adapter or is it possibly too old to achieve a faster download speed or should it be replaced?
