In many ocassions you have MUCH better support from the OpenSource community than from vendors …. Look at Ubiquity and Mikrotik, supporting a very reduced set of transitions mechanisms. I’ve many WISP that have big troubles to keep growing because that, and you know what, at the end they reflash that “nice” hardware with LEDE, and done!

It's interesting to see enterprise customers adopting OpenWRT/LEDE despite no official support from CPE vendors for 3rd party firmware on their products. > Regards, > Jordi > > -----Mensaje original----- > De: Loganaden Velvindron <logan@hackers.mu> > Responder a: <logan@hackers.mu> > Fecha: jueves, 28 de diciembre de 2017, 10:52 > Para: <jordi.palet@consulintel.es> > CC: <nanog@nanog.org> > Asunto: Re: Implementing 464XLAT at a small WISP > > On Thu, Dec 28, 2017 at 1:11 PM, JORDI PALET MARTINEZ > <jordi.palet@consulintel.es> wrote: > > Nice ;-) > > > > I’ve been doing this for some time already … and have trials with several customers (tens of thousands of customers). > > > > Note that most of the routers that support LEDE (quite a big list), will work by default with a standard stable release. > > > > I'm curious about the limits in terms of number of users from running > OpenWRT/LEDE on this kind of gear.
