My original problem turned out to be hardware related, apparently you need a device that is capable to provide enough power to the minipci slot to power the 700mW SR9. The symptoms were all sorts of hardware weirdness and status codes and I kept seeing "no carrier" on one side. After moving the card to a more powerful test device, the problem was resolved. My test setup was as follows: STA side: WRAP.2C + SR9 + 900mhz 3dBi omni AP side: Soekris Net4521 + SR9 + 900mhz 3dBi omni I tested two quick scenarios: one with both STA and AP side-by-side and the other with AP & STA on two different floors. In both cases the AP was connected to an existing live network and the STA had a laptop attached to its ethernet port. I tested throughput with a large FTP transfer from a server behind the AP to the laptop (for lack of a better tool). I was actually able to achieve a higher transfer rate while going between floors. Probably due to the RF propagation patterns of the antennae and the way they were positioned in the side-by-side scenario. The throughput test yielded sustained approximate rate of 9.6Mbit/sec and 12.8Mbit/sec when side-by-side and between floors respectively. One interesting thing to note is that the STA (WRAP) side always reported an RSSI higher then the AP by about 10 points. I also grabbed output from athstats if anyone is interested. Overall, everything worked well once the hardware issue was resolved and I look forward to deploying some point-to-point 900mhz links over longer distances with some more powerful antennae. Many thanks to Sam for his work and continued support. Yuri
