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)?

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
