i get my device in a few hours from now.
Is this one better than the virgin asus or worse or no change?
I see no real difference. To be honest I was not able to investigate any further. I think the 5 GHz radio might be the only problem left. There might be some minor things with LAN/WAN access and the missing LuCi but this is no device specific stuff and just a flavor that might fit for the final stage.
I had to pull Luci to keep the image size small enough with adding all the drivers.
I will see what I can do for the 5GHz again in a little while.
I found USB. Its documented in the Wiki now. 
I'm letting the glue set. I used a header connector so I can change out the USB from client/host . I have the datasheets for the both chips and am figuring out the SPI that is shared with the GPIO I'm pretty sure the unpopulated pads right there are resistor, decoupling cap and a diode for the usb. The dev board have schematics and they are saying that a certain voltage to ground on the D pin will change the mode. I also have the previous OEM firmware boot log before the k3 one we both used.
Wow this is even better than my discovery. Very impressive.
So you think there might be a SPI bus somewhere?
just above the usb pin holes on the left 2, LED side you can see the 3 unpopulated pads for usb host/client
SPI im still looking for, poking around with my raspberry pi 3b+

SP2 SP1 CT2 CT1 pin holes, if the chip is on board somewhere we might be able to actually setup real POE and not the passive shit it has, make it a real PD

so digging through this list, Take the ones with 8mb flash 64mb ram, abgn+ac the 7620a as ROC 2.4ghz, 7612e as the 5ghz and the 7620a as the switch and 4 port 10/100 and 2x2 x2. and usb, Then we might have a better image to get on the device.
the 5ghz is using PCIe for com to the 7620a so that is what I've been missing. Been quite the adventure last 8 hours..

tomorrow. gnight. You can use builder, i has 19.07.3 on openwrt and snapshot head in snapshot/openwrt just do the mace clean, rm -rf .config and go to town! just ssh to the server with the files. to get the files onto the webserver you need to move them to /var/www/html/WHATVER_FOLDER_YOU_MKDIR . I havent symlinked anything or changed permissions so you will need to use root with su - and the pass. all passwords are the same.
Hello,
I got a 7-Links model as a product tester some month ago. As described here a connector get's broken after stormy weather.
Now I got 2 "orginal" WavLink models from Amazon. The first thing I did, was opening the devices :).
It looks that the 7-Links and the WavLink models are really the same hardware.
Only the Zentel RAM chip starts with A8R12E40CBF not A3R*. I did not find anything about this number. And I verifyed that it's realy A8R not A3R ...
I'm wondering about the firmware used on your device, since it's for the WN535 and not the WN572 model.
I see: I will have to do more investigation if I got time to do so.

Hello,
nice to read your first hand experiences with both device types.
As my device will get installed on the ship in a few days I started to focus on another little hardware hack.
I will install a Bluetooth module (with SSP). This will provide a simple UART solution even if installed "unreachable".
Nevertheless I will be unable to be near the hardware anyway. I may take the device "home" for the winter if possible. But I am not sure about that too.
I was thinking an ESP32 for BT so I dont have to keep opening the case too!
An ESP32 would be nice too.
I will try a HC-06 like module for now. Its cheap and will work hopefully.
LXK-6626 is a wifi amplifier
Do you have a datasheet. I was not able to find it.
It may be compatible with:

On my WavLink AC1200 the installed firmware is named M72HG3.V5030.200609
and I'm still waiting for registering at the wavlink website.
They are working on this problem 
@muebau
How do you power the device on your ship? My Sunbrige 2255 Bayliner has only 12V on-board voltage. But passive POE requires 24V here.
@All
Just a question of a clueless. Why you have choosen Asus RP-N53 as base? When looking in the devwiki page I found some models with MT7612EN chipset, and only 8MB flash, like the Netgear EX3700/3800. And since they are supported on openwrt, 5GHz wifi should be useable with these devices too.
Hello @fow0ryl,
as the synchronous buck converter of the device is able to handle input voltage from 4.5V to 27V it should be fine with 12V. That said I decided to use a " MT3608" step-up converter in conjunction with a CAT6 15m CCA Ethernet cable for outdoor usage.
According to the specification the cable should be good enough to resist UV light, oil, salt water and rough conditions. I think there might be some voltage drop with the 15m cable. To make sure there is enough power the 12V of the ship is boosted first to 24V by the MT3608 and inside the device used by the internal buck.
I am not sure if it is really needed but this way there is no doubt.

Well I used the first working firmware image and started to investigate. After that @frustro was a true hero in the firmware section.
So @fow0ryl if you would provide a better working config (or firmware) it might be the hint to solve the problem. Sometimes its just this simple as someone with a new idea to go a step back and think it over again.
