Good!

I don't really think this change should affect your speed at all. A more
reliable test of performance would be to use iperf against a machine
with a wired connection to the same network, if possible, and make sure
that you're using the same network with all kernels. If it's a network
with multiple access points then you could get different results though
depending on the AP you happen to be connected to, channel, etc.

You could check /var/log/syslog for the string "disconnect", e.g. 'grep
-i disconnect /var/log/syslog', but that could contain logs from prior
boots so you could get false positivies. The particular problem I was
seeing (disconnection due to beacon loss) result in messages like this:

wlan0: CTRL-EVENT-DISCONNECTED bssid=xx:xx:xx:xx:xx:xx reason=4
