@csknzdmr I have built an OpenPli image for Solo4K as a router, to test the wifi / hardware as a router capability, it's work quite well , but it was required to recompile the kernel in order to achieve that, but just for AP this is not necessarily, however hostapd and bridge-utils apps are required.
Your Duo2 had with the original image the AP plugin?
If so you can try to install the plugin from their repo, you can test this by installing the latest image on your VU and see if it have that, if so copy /etc/opkg folder on your hard disk, or an usb device, also do an "opkg list-installed > vu-packages.txt" and copy the resulted file as well on the same drive as previous folder.
Install your preferred image and start download your plugins
From opkg folder previously saved you can take the web URLS to download packages, probably you will have few urls as those ones
h**p://code.vuplus.com/packages/openvuplus/3.0.0/vuplus/feeds/stable/vuduo2
h**p://code.vuplus.com/packages/openvuplus/3.0.0/vuplus/feeds/stable/all
h**p://code.vuplus.com/packages/openvuplus/3.0.0/vuplus/feeds/stable/mips32el
You will need to go through all files and take all URLS, and at the end of those URLs you need to add /Packages.gz for example the resulted URL will be alike that
h**p://code.vuplus.com/packages/openvuplus/3.0.0/vuplus/feeds/stable/vuduo2/Packages.gz
After that, you will need to download all Packages.gz files from all urs and decompress them in text files, search in those text files for your plugin name, you can find the plugin name in the previous exported installed packages list "vu-packages.txt".
If you find your package you can download the package from it's own URL, in our case le see we want enigma2-plugin-demoplugins-tpmdemo package "ipk" file, search for this in decompressed Packages.gz file for enigma2-plugin-demoplugins-tpmdemo and will see something like this

If your Duo2 doesn't had AP plugin it is possible that your wifi hardware to not support this mode.
