Since I got my computer I have always had it plugged in and wired to my router, although this is no longer possible. As my motherboard does not have a build in wireless connector I recently purchased the Asus PCE-N10. On a wired connection I get and average of 50mb down and 5mb up, after I installed this card and ran the test I was getting under 10% of that with a download speed of around 5mb and an upload under 1mb. Is there any reason for this, the adapter had decent reviews, it just seems such a drastic drop.
