Hello guys.
I have a TP-Link CPE610 that I use as client to connect to a public access point that is a little congested. Sometimes it can take more than one hour to successfully associate to the AP, however I have tested a CPE520 with stock firmware and it associates within few minutes.
I'm aware that openwrt's wpa_supplicant adds an incremental delay between failed connection attempts. To avoid this, I wrote a script that checks every 15 seconds if it is already connected, and if not, it resets the interface to restart the counter. That way every 15 seconds it performs a new attempt to connect.
I'm wondering if I could change any settings in openwrt to imitate the behaviour of the stock firmware. I'm pasting below an excerpt the logs of both devices, in case it's helpful.
Any help would be appreciated. Thanks in advance.

That repeats over and over until it finally gets associated and receive dhcp settings.
