Frequently Asked Questions
How do I log into my extender's interface?
You can log in by launching a web browser and entering the user-friendly URLs: http://mywifiext.local/ or http://mywifiext.local/.
What does the blinking green Router Link LED indicate?
It indicates that the extender is currently booting up.
How do I check if my router filters prevent devices from connecting to the extended network?
If your router's MAC filter, WiFi access control, or ACL is enabled, you must provide the translated MAC address for the device so it can connect and receive an IP address.
What should I do if the Router Link LED shows solid red?
Solid red means the connection quality to the router is poor. You should move the extender closer to your router and try again.
