Some possibly useful information:
1. wpa_supplicant's verbose logs. On my computer it is normally
started with -B to run in background, and when I want to investigate
an issue I run it without -B and with -dd to get a verbose log in the
console.
2. What version of rtlwifi firmware is loaded? Look it up in dmesg.
Other relevant strings from dmesg may be helpful too.
