Just dropping in another firmware won't magically fix anything. Firmware and driver need to be in sync for things to work. I picked the lowest FW version (46) the device supports because this means the least amount of changes had to be made relative to iwm(4) code (the iwx driver code was derived from iwm). > What do you mean by specific environment? > It is a PCI-E card installed on my desktop.

Sounds like you have 'ifconfig iwx0 debug' enabled? I don't see why SCAN messages would appear otherwise. Frequent printing to dmesg can interfere with regular operation. Please only enable 'debug' if really needed. > I tried to measure the speed as soon as I got a desktop working, and it > goes from some hundred to 800/900 Kbits per second. > Probably this very slow rate has to do with unlucky firmware and continuous > connection resets. > Gmail is not able to load, for example. > > What is the speed you get? Is it stable? It is working OK for me up with up to somewhere around 20 Mbps. Linux can of course drive the device to be a lot faster than that but we don't support full 11n, let alone 11ac, yet.
