OpenWRT on a Netgear DM200 ADSL Modem


Another bit of craptacular consumer tech gets the boot.

Ever since picking up a new DSL modem a ways back I'd been wanting to get OpenWRT up and running on it. That process turned out to be ... involved. Though with a bit of path-smoothing it could have gone far better.

The major pitfalls encountered were:

  • Determining which OpenWRT firmware to install.
  • Determining how to recover from failed attempts and revert to Netgear's OEM firmware.
  • Properly configuring the WAN DSL interface.
  • Having the appropriate documentation available whilst offline during various experiments.

Also, as a suggestion, always remember you can use your mobile phone data connection if you somehow corner yourself
