    Re: Howto: Ralink RT2860 (m)PCI(e) (RT2760/RT2790/RT2860/RT2890) on Intrepid

    Hi!

    I have followed this guide twice.
    Some time ago I installed Lucid and followd this guide.
    Everything worked perfectly! I could connect to my WPA2 secured SSID and got a link speed of ~270mbps.
    I could transfer files at ~9-11 MB/s from my Win7 desktop.

    A week ago I reinstalled Lucid on the same computer but on a larger, newer, faster SATA drive.

    I followed this guide once more but now my transfer speeds max out at ~2.5 MB/s
    Link speed is still at ~270mbps but signal drops to low when transferring files (only the "dot" and one "bar" in NM-applet).

    I reconnected the old SATA drive and transfered some files and behold! The old install still reaches speeds up to 11-12 MB/s!
    Signal is max in nm-applet, sometimes drops to max -1 "bar".
    The average transfer speed is ~9.3 MB/s on the old install and in the new install ~2.5 MB/s, peak 4 MB/s

    I can't figure out what could be the difference between theese two installs, could anyone please point me in the right direction or give some tips on how to troubleshoot this?

    See above, THAT is the difference.

    Try getting a stronger signal and see if it makes a difference.
    Maybe the new drive is spewing out more RF noise

    The router is ~3m from the computer, concrete wall in between.
    The new drive was formerly a USB connected external drive which I have taken apart, since I didn't need 2 TB external storage and wasn't happy with 160GB internal
    (only have one SATA connector on MB)

    Point is, this drive used to sit on top of the computer, connected through USB when i received higher throughput.
    Sure it could be that by removing the casing and putting it inside of the computer it produces more RF noise but it seems far fetched to me :/

    I will test later to see if the signal and throughput improves when moving the disk further from the antennas.

    Edit: Seems to be a problem with the motherboards PCI bus. Other MB and all is well.
