Hello dslconvert,

I extend my gratitude to you for contacting us about this issue through the forums and please, accept my sincere apologies for any inconvenience

that you have experienced.

The DNS servers are automatically assigned to your DSL modem.  However, it is still okay to hard code the DNS servers as long as it is the one assigned by the AT&T server. Changing your speed plan would not require you to hard code the DNS servers on your modem.
