How do I reset my DIR‑857 to factory default settings?

If you forget your router’s admin password, you can perform a factory reset of this device.

Step 1 – While the router is powered on, insert the end of a paper-clip into the pinhole on the back of the router, as highlighted below.


Step 2 – Holdthe paperclip down for 10-12 seconds, then release.

Step 3 – The router will automatically reboot. Once the WLAN light stops blinking, the unit has been reset.

1. Resetting the router does NOT restore the firmware to an earlier version; it simply changes all settings back to defaults.
2. The factory default username is Admin there is no password
