[lime-users] DSL modem - router compatible with LibreMesh

I see DSL modem-router combo devices on OpenWrt... Any experience using them with LibreMesh? Are all the necessary config options accessible, either though GUI or CLI? The public ISP here has just informed is that after all it may be impossible for them to sell us a fiber optic connection in the town we have line of sight to, so we're looking for ways to improve our DSL quickly whole we figure out our longer-term strategy. ~ Pato
