It is a Prism 2.5 chipset. Performance... When transferring a 10 meg file between the systems I'm getting a 450 KByte rate with WEP disabled. 350 KByte with 128 bit WEP enabled. Does the 128 bit WEP really have a 25% overhead? It varies between manufacturers, but there is a definite, measurable hit by turning on WEP. 25% doesn't seem unreasonable. Ahhh, the cost of security! Are these transfer rates normal for WiFi at 70 feet? There's no universal yardstick. You could try using a parabolic reflector to increase gain at either (or both) end(s) of the connection. Lewis, that's true but parabolic antennas are really expensive and for less money I could simply dig a trench between the two buildings and drop in a Cat 5 cable and run at 100 Mbps. It would be less than half the price and 10 times the speed... Why not? Don't need the speed for the application I have and I'm now fascinated with WiFi... :-) I have a 5db gain omni-directional antenna on order for the MA311. Will that help? Probably. Also try adjusting the placement of the antenna/AP. It's amazing how even a few inches can improve transmission. Also, try adjusting the relative positions of the antennae at the AP (like TV rabbit ears). I've done that so many times I'm worried about wearing out the antennae! The driver... It looks like the driver boots up with the radio off or something. This indeed sounds like an option in the NIF which may not be well documented. Jens can probably speak to this. Jens did help me fix that problem! Thank you again Jens! Stability... With all of the above considered, the MA311 somehow decides, after about an hour, that it is time to quit work and it goes "unavailable". Nothing will bring it back short of a reboot. Please! What am I missing here? Hehehe... Welcome to the brave new world of Wi-Fi power management (or mismanagement, as the case may be). It sounds like the card's power management functions are being enabled, and unfortunately, Wi-Fi cards of today's vintage(!) are notorious for being unpredictable when power management is enabled. As there are no standards for power management Lewis, it turns out not to be a power management problem. For some reason the MA311 likes to receive data but when it has to transmit data it falls into an unrecoverable coma... Any help with the above will be appreciated! - ray No problem! That's why we're all here! (Of course, you could try calling Netgear..."OS/2? Is that something like OS X?..." Don't get me started... Positive and sunny thoughts are now being replaced with negative and dark thoughts... . . . Back in control... I think... ;-) . . .
