Just tried it. It doesn't make things worse, but nether better. It seems that I can fully control speeds using iwconfig, and when speed drop, I see that there. Now speed dropped to 48 Mbits/s raw or 2.9 Mbytes/s real upload. But I can reset it to 54Mbits/s, then set speed to auto, then it will be 3.1 for a while, then drops again. On the other hand speed is quite stable, it drops once in a while due to scanning for few seconds to about 2.2 Mbytes/s, then restores itself again. This was more or less the same as without this patch (I also use hw scanning now). Anyway, it is almost perfect. All I need to do it to set speed to 54Mbits/s manually.
