    I'll preface this post by stating I ignorant of several concepts of 802.11n which brings me here.

    Router:
    Linksys E3000 Firmware Version: 1.0.03
    5GHz radio @ 20MHz, 40MHz or AUTO (Currently Disabled)
    2.4GHz radio @ 20MHz or AUTO (Currently set to AUTO)
    WPA2 Personal

    PC:
    HP dm4-1160us
    Win7 Home Premium

    Adapter:
    Intel WiFi Link 1000 BGN (112BNHMW) (2.4GHz only)
    Sell Sheet
    Current Setting:
    Channel Width Auto (no option to force to 40MHZ)
    802.11n Mode Enabled
    WMM Enabled

    Physical Environment:
    Router in same room as laptop, perimeter walls only, tested up to 40 feet away, in separate room and outside building.

    The advertising for the Linksys router, the Intel Adapter and (some) for the HP laptop all indicate 300Mbps should be attainable. I am consistently getting 144Mbps (sometimes dipping to 72Mbps) with full signal at all locations. Wiki (I know) correlates that data rate with 2 spatial streams @ 20Mhz. 300Mbps is theoretical max for 2 spatial streams @ 40Mhz. I am assuming that since I can't get 40Mhz at 2.4Ghz that the Intel 1000 will never reach 300Mbps. Is my only option to upgrade to an adapter with a 5Ghz radio to see more than 144Mbps?

    The Intel 6250 shows as an option in the Hp dm4 Service Manual with what appears to be the same antenna configuration. If I upgrade to this, should I see more than 144Mbps?

    PS...Don't force the 1000 into the 5.2Ghz band using the Intel Connections Settings unless you enjoy restoring your OS.

    Adding: I did confirm that my laptop has 2 antenna leads connected to the current Intel 1000.

    Well, it appears there may be a combination of factors affecting my link speed. Primarily the E3000's inability to channel bond at 2.4Ghz and the Intel's lack of a 5Ghz radio. I'll see if DD-WRT will unlock 2.4 channel bonding for the router. If not, looks like a 6250 is in my future. I don't really need WiMax but it will be fun to play with on a day pass. Now what to do with that empty WWAN slot?
