Well I already had it flashed with the Jasager firmware so I was getting rid of that so it could be used as a normal router.
And to answer your questions, yes and yes (modem). It may just be a setting that I can't find.
After flashing my Fon2100 with Openwrt and adding the the webif interface I can't get any internet through the Fon. I'm not wanting to use Jasager, just want a normal compact router. Any suggestions?
