said by balur:Working in DSL support.
The only issue I had with DSL is with CenturyLink. I had a Cisco 678 from 5 years ago (when we had Qwest).
The tech support is from India (yes, they forgot to hang up and I heard the conversation between the co-workers). Not to mention, they didn't know the difference between PPPoA and PPPoE.. which is a massive FAIL to me. I even told them I was an advanced user.
Needless to say, I found out they converted from PPPoA to PPPoE, rendering my little Cisco 678 useless as a router. It still works fine as a terminal with my main router connecting using PPPoE.
I did switch to an Actiontec M1000 using PPPoE. It works decent and it supports a few newer technologies. I still keep my Cisco for backup purposes in case the Actiontec dies.
