My netgear DGN2000 router has an annoying bug where the IP address reservation refuses to reserve addresses for devices with MAC addresses that don’t begin with 00. This happens when you:

  1. Log onto your router at
  2. Click LAN Setup
  3. Click Add at the bottom of the central frame
  4. Click on the device you wish to reserve an address for
  5. Press Add

An alert that pops up saying “Invalid MAC Address, please enter again!”

Half of my devices have a mac address that begins with something other than 00, so this is annoying. Thankfully the validation is only done in javascript so it is very easy to subvert. Simply turn javascript off in your web browser.
