Did you verify it's actually running on 802.11n?
Are you using 2.4GHz or 5GHz? If your router supports it, try switching to 5GHz.
You can also try different channels that might have less interference.
I just ran a speed test next to my router I got 54mbps down! Took it back to my living room and got only 25mbps! I dunno how much ghz my router supports and I dunno how to check if my chip is actually running on 802.11n! I have this router btw »www.staples.com/Netgear-N300-Wir···t_746737
I did have a technician that came to my house once to repair my cable told me I should get a gigabit router to get max speeds but I didn't know if he's right.
