There are so many guides online for how to unlock the Bell 2Wire modem. Most of them are using Singtel firmware.  SingTel’s firmware is better than Bell’s firmware but I like the CenturyLink’s firmware.  It has a clean interface and you can setup password to protect. You can download this firmware from their support website hereIt may ask you to enter the zip code, you can use this 55401. Down the list you will see 2Wire 2701/270HG, expand it by clicking the plus sign and click on windows or Macintosh and following the instructions to download the firmware.  


I have writtien a full guide how to upgrade the firmware and configure it as regular dsl modem or access point here
