Connected at 130 mbps but getting actual transfer rates of 16 mbps (2 MB/s)

My problem is that I can't get my actual transfer speeds to be even REMOTELY close to my connected rate of 130 to 270 mbps on my N card.

I have a Linksys WRT310N router with a Windows XP laptop with a Intel Wifilink 5100 AGN card connected at 130 mbps. I have a wired gigabit linux server connected to the router with a samba fileshare.

• When I turn off my wireless and wire up the laptop to the router I get transfer rates of 16-17 megabytes/s through samba and sftp.
  
• If I put my laptop on Wireless N and get 130 mbps (let's say I get even 65 mpbs which should be 8 MB/s), my transfer rates on the same samba and sftp shares go down to 2 MB/s or 16 mbps.

16 mbps of actual throughput for something that is displaying as 130-270 mbps seems wildly incorrect.

I've updated ALL of my wireless and wireless related drivers for my Intel Wifilink 5100 AGN. I wonder if that's the case. To me it seems that the problem resides in either my routers wireless settings or my laptop's wireless settings, but I don't know what to do to actually isolate the problem.

Any help would be appreciated!

Try running a test to see if your TCP settings are in range.

You may need to adjust RWIN,MTU settings to improve performance.
