Weird ... I am not sure how the numbers on the bottom right of the window works. If I scroll to the message, it says "178/185" but if I click on sharing, the link has a "183" . Anyway, yes.
I think would be better to be able to use the wifi to set up the router. It is a lot more convent even for router with wired connection. All consumer routers comes with a WIFI password printed on the box to prevent people to have the user leave them open without a password.
Assuming that all Openwrt firmwares can access the original MAC address and the MAC is easily available to the user, a solution would be to create a default WIFI password based on the hash of the MAC address. People can even use a web page to get it. To avoid easy hacks, Openwrt can set the WIFI's MAC to a something different until a different password is set.
If you want to be more secure, you can just provide a command line tool to embed the first boot password in the firmware image before flashing.
The configuration on a file on media is easier to implement though.
FAT is enough. It can be created, read and written on pretty much any OS. It is also relatively small and for a device sold as "SD reader", it seems already a must have anyway.
What is the impact of having FAT filesystem support for generic on only the devices that need it?
Pros: More people can enjoy Openwrt on a device they own.
Cons: I do not see any. I could understand if adding support for the ZSUN would create problems for other devices but I do not see any. It looks like other devices already have it: https://github.com/openwrt/openwrt/search?utf8=✓&q=kmod-usb-storage . Am I missing something here?
I know a fair amount of people that do not have ethernet cables at all in their houses but everybody has a SD card or a USB drive.
At the moment, more people can use USB port and SD cards than a wired Ethernet connection. The previous generation of Apple laptop had a SD reader but not a Ethernet connection by default. Even on the latest models, the standard dongle that people buy has a old USB port, HDMI port and a SD reader but not an Ethernet connection. And even a few slim PCs do not have the a Ethernet port.
Last thing. You wrote:
anyway, you can always propose the idea on the mailing list, discuss it and try to convince others.
Is the mailing list better than https://forum.openwrt.org ?
