The connection got deassociated due to reason 34; that is:
Disassociated because excessive number of frames need to be acknowledged, but
are not
acknowledged due to AP transmissions and/or poor channel conditions.
There isn't really anything I can do about this; as it would be most
likely caused by high interference; low signal, etc.
Please check if you can improve the signal received by your device in
any way, such as moving closer to the access point, adding access
points, or moving the accesspoint to a different channel which may have
fewer interfering devices.
