Glo Running browser without Wifi connection

Hi,

I am using kiwix-serve to have a static copy of Wikipedia (on a SD card) to my Kobo. It works, but, as the dump is served using HTTP, I have to connect to localhost with a web browser to read it. However, the Kobo's built-in web browser refuses to work without an active Wifi connection, which is sad as the point is to read the dump offline...

Is there a way to bypass this check or fool nickel into believing that wpa_supplicant is connected to a network? I tried writing into /tmp/nickel-hardware-status following what is done by /etc/udhcpc.d/default.script, but this doesn't seem to change anything. I tried running an strace on nickel with and without a Wifi connection to see if I could identify how the check was performed, but I wasn't able to find anything. Any other ideas?

Thanks!
