I tried the current kernel for precise 3.2.0-26-generic with and without linux-backports-modules-cw-3.3-precise-generic on my lenovo s205 with RT3090 chipset. The problem still exists. After some time wireless speed no longer exceeds approx 70KB/s. While downloading data at this speed, the roundtrip to the access point increases drastically
