You are not alone in getting less than ideal speed. I performed an experiment and the wireless speed is significantly lower as compared to that of my TP-link router (TL-WR941ND, via bridging). Test results below are performed using same conditions (distance from router, laptop, around the same thing of the day etc) except for the router used.

when i use direct connect to server, my connection is this fast
This one is connected wirelessly when i'm very near to the router.
Finally, this last result is via wireless from my room which is not far from living room.
May i know why are the results so drastic? I am using maxinfinity 100mbps with the dlink router provided. What do i need to boost it to maximum capability?
