WAVLINK Quantum D4G router (model WL-WN532N2)

I recently purchased a WAVLINK Quantum D4G router (model WL-WN532N2)
https://www.wavlink.com/en_us/product/WL-WN531G3.html

I got the router for a very good price ($35) and I found the router to have excellent wireless coverage and bandwidth, especially on the 5G band.It also has 1 GB WAN and LAN ports.
However, I found the stock firmware to be VERY basic as far as configuration options, so I thought I would look to see if OPENWRT had any custom images for this router.
I found nothing here, but Lo and behold, I noticed a samba share on my network named OPENWRT, and it resolved to my router's IP address.
Long story short, it looks like WAVLINK is using OPENWRT as the stock firmware (although a poorly implemented version), at least as far as features are concerned.
I opened up the stock firmware image with 7zip and found some useful things:

My first question is this:
Do any of you OPENWRT gurus see how I might be able to telnet or ssh to the router under the current image ?
I tried port 2323 as listed in the firmware file but it is not accepting connections.
I would prefer to make changes via command line before I try to build a new firmware, but that is my ultimate goal.
I would greatly appreciate any advice any of you might have.
Thank you so much.
