What should I do if my range extender stops working after forgetting my login password?

Connect to any network except the one managed by your extender, visit http://tplinkrepeater.net or use the TP-Link Tether App. If using a TP-Link ID to log in, click 'Forgot Password?' on the login page and reset it following instructions. Otherwise, refer to FAQ Q1 to factory reset the device and set up a new login password.
