6. Save the settings:

a. At this point, you should save the settings. The emulator doesn’t allow any-

thing to be saved. It reverts back to defaults when you log out or disconnect from the Web site, so clicking Save Settings won’t do anything. But on an actual DIR-655, the settings would save and a reboot would be necessary.

b. It’s also important to back up the confi guration. This can be done by clicking

Tools on the top banner, then System on the left side and selecting Save Confi guration; this is a real time saver in case you have to reset the unit. It is also wise to update the device to the latest fi rmware. Save your settings before doing so because they will be lost when the upgrade is complete; if saved, they can later be loaded back in.
