While I believe Broadcom sold off its wifi business and the recipient vendor recently opened its driver (and there was a reverse engineered driver already available), I don't believe the DSL chips had a similar change. > > ​ - Jim I'm a strong proponent of staying with vendor firmware on DSL equipment. DSL is such a dicey technology, running on crummy copper lines, with lots of odd protocol options, variations, etc (and ATM (?!)). It gets hard to defend an outage/trouble report when they ask, "What kind of modem do you have" and you start to tell them that you hot-rodded the modem to use some lunatic firmware with anti-buffer-what? :-) So I stick to using their modem. That goes double for a Zyxel that's bonding two pairs: just plug the LEDE router's WAN Ethernet into it, and the bits go in and out. Don't peer too closely at the man behind the curtain/sausage being made. If they're not delivering anything close to their promised/estimated speed, then you have cause to complain. In their defense, I will say that the Fairpoint techs on the support lines are halfway (or quite) knowledgeable, and are supportive of either of these cases: - I run my own router. - I put the DSL modem in bridge mode, and let the router supply PPPoE credentials But letting Fairpoint-supplied equipment handle the physical link seems good to me. My two cents... Rich
