Well, I just tested a 500Mbytes bulk transfer and I got a mean throughput of about 5.5Mbit/s, it was a simple infinite wget loop so we can have some slowness due to TCP. However no errors were logged to syslog and the AP is still there, it didn't complain about anything. I built kamikaze yesterday image (r14144), kernel 2.6.25.17, I used the AP as a station joined to another AP without encryption. By the way, we did thousands of tests with x86 and we came to the conclusion that there is no performance (throughput) difference if compared to the standard proprietary firmware. Cheers, -FG
