kill otus. Unless you really want it to steal the device.

^^ again MCS.
Have you actually patched the driver?

and? your ap (what is it btw?) has (silently) kicked you...
you would need to put one interface into monitor mode and
sniff what really happens.

again same as before, patch the driver (or migrate to carl9170).
If you are unfamiliar with the procedure you could also
reload mac80211.
modprobe mac80211 ieee80211_default_rc_algo=minstrel
(note, other drivers might depend on mac80211, you have to unload
them first.
lsmod | grep ^mac80211
will tell you which).
Afterwards, verify that the system really loads the new module.
Or took the new default_rc settings(see
/sys/module/mac80211/parameters/ieee80211_default_rc_algo )
