• Could you help me to set better parameters for my server? I use mac filtering. I have D-link DWL-G520+ 802.11g card.

    Is Tx power good? Is it good to take off power management (first delay is very high)?

    linux:~ # iwconfig
    lo no wireless extensions.

    sit0 no wireless extensions.

    wlan0 IEEE 802.11b ESSID:"default"

    and ping:

  • Hi Poy:

    A server is usually Ethernet connected rather than Wi-Fi connected. Reasons are higher bandwidth and more predictable bandwidth.

    An AC powered Wi-Fi connected server would not likely benefit from power management. Power management is for battery conservation.

    Transmit power level is a function of communication range. Higher power equals higher range. Lower power equals lower range and more room for multiple BSS's.

    I am sorry I have no experience with Wi-Fi on Linux.

    I hope this helps. Can you add your location to your forum profile? Thanks. /criss
