After moving from my home office to a real office I decided to downgrade my premium 80/20 business fttc connection (from claranet) to a residential 40/10 service from sky.

Yesterday, the connection was changed over and I found myself with no internet. I initially thought it was because the pppoe username and password needed updating (tail /var/log/messages was showing a CHAP authentication error message) but I don’t recall ever being sent a username/password. It was then I had a flashback to many years ago having to extract the details from a router/modem in order to use them in another device. A bit of googling backed this up, but also suggested the connection doesn’t use pppoe but MPoA and was going to be even more challenging to setup; http://www.skyuser.co.uk/forum/sky-broadband-fibre-help/51550-ubiquiti-edgerouter-lite.html

But this article was written in 2013, surely someone has documented the process more recently? Fortunately, before starting the long-winded process I stumbled across another aritcle; https://community.ubnt.com/t5/EdgeMAX/Sky-Fibre-DHCP-client-option-61/td-p/1172347. However, this seemed to point to needing a different modem (such as the Draytek Vigor 13) to achieve the MPoA connection.

Before I went and bought a new modem, I thought i’d try the BT Openreach/Huawei Echolife HG12. I deleted the pppoe interface from the Edgerouter and set the address on eth0 (connected to the modem) to DHCP. Still nothing… welll both of the previous articles did state the need to add the DHCP option; send dhcp-client-identifier "user|pass"; so I guess it’s time to unbox the Sky router and do some packet sniffing?

I must be in luck… 2 weeks ago, a post suggested you no longer need to use logon credentials, passing anything in the dhcp-client-identifier will do the trick. The example given was;

 client-option "send dhcp-client-identifier "bacons";"

So I gave it a try, but still no dice. Worth a reboot I guess? Power cycled the modem and voila, we have internet! Well, that was simpler than anticipated.
