No that doen't work. They updated from Sas to walledgarden.
If you change your modem it should gige you a 10 dot IP. When you open the browser it should take you to the Reg site. Use your account number and the last 9 of the same number as the password. It will ask if you want to replace the modem just click yes.
If for some reason your dns doesn't take you there the address is »walledgarden.mchsd.com
I upgraded my modem just a few weeks ago and I thought I used the SAS website. But I could be wrong, perhaps I used walledgarden.
Though the rest of the information in that post is still valid.
