It looks a bit short and complicated for me. Where I can read how to flash in details? How use this serial port and where it is? Is it possible to do all from win10 machine or I need Linux?
If the page doesn't provide enough info about installation over serial, you can check other devices pages on OpenWrt wiki. It should be very similar.
You will have to trace it or possibly look for images online. If you are lucky you might find an images as which pad is which. Also it would be good to look at other devices pages on the wiki to see if there are general advices in making the connection. And make sure you choose a TTL adaptor not a standard DB9 232 adaptor.
Thank you.
Unfortunately, this device a bit rare, I can't found any info about technical details of wre6606, just nothing.
Is it any chance to install Openwrt throuh original firmware web interface? May be in next versions?
If no, I'll try to flash via serial. I have this one serial adapter, not sure is it suitable or not?
