On the laptop that I mentioned, this problem was only happening sometimes.
I did not figure out what actually triggered it.
Most of the time the throughput was similar to what you posted here,
but when it went down, it went down right to 100-120 KB/s

Could it be that this is triggered by the use b/g protection mode due to reception
of foreign beacons of B devices by the AP? Has anybody tested RTS/CTS in detail?
