This definitely looks like RF problems.  Especially this:

[  177.575000] wlan0: send auth to b4:07:f9:49:cc:65 (try 1/3)
[  177.595000] wlan0: send auth to b4:07:f9:49:cc:65 (try 2/3)
[  177.605000] wlcore: EVENT on mbox 1
[  177.605000] wlcore: MBOX vector: 0x100000
[  177.610000] wlcore: MAX_TX_FAILURE_EVENT_ID
[  177.615000] wlan0: send auth to b4:07:f9:49:cc:65 (try 3/3)
[  177.640000] wlan0: authentication with b4:07:f9:49:cc:65 timed out

You are send auth requests out, but not getting anything back.
Apparently you're not even getting ACKs (as pointed out by the
MAX_TX_FAILURE_EVENT_ID).

Do you have a sniffer? You could try to use your TP-Link dongle with
wireshark to see if it works fine as a sniffer.

My bet is that you'll see lots of retransmissions there. :\
