I want to know whether the performance of hardware depends on Drivers which were installed. If so how could we know the best driver.
I am asking this question because the wireless firmware RT2870/RT3070 which performs well in Windows and the average ping time is low when compared to Linux i.e OpenSUSE 13.1.
To be specific I have a WiFi Adapter RT2970/RT30370 and it works fine in Windows and the ping time is 1 ms whereas in Linux I experience less signal strength as well as high ping time with 4-5 ms. I also face disconnections in Linux.
After turning OFF power management I could see much better ping times but the signal strength remains the same. Also I want to know the relation between power management and wifi performance.
Can you share the iwconfig output so we can see RSSI level?
Also I want to know the relation between power management and wifi performance.
I can’t help with the level of detail you want with regards to how dynamic power management impacts on a given wifi chipset - that might be a good developer question.
All I know is that some users report degraded performance with it enabled, so unless you need to conserve power, I recommend leaving it disabled.

A quick search does turn up a lot of threads reporting the same. This is not really an openSUSE-specific issue. As such, I can only recommend posting this question here

Hi
Can also be channel interference (as in other AP’s close on same
channel), router bandwidth and sideband settings as well (40Mhz on 1x1
to get full speed).
