My router security is WEP, and I entered the wrong password
or security key on the extender. I cannot access the extender
anymore. What can I do?
The extender cannot check to see if the WEP password is correct. If you
entered the wrong password, your WiFi‑enabled computer or mobile
device is not able to get the IP address from the extender. You must reset
the extender to its factory default settings to get the IP address back.
I enabled a WiFi MAC filter, WiFi access control, or access control
list (ACL) on my router. What should I do when installing the
extender?
When the WiFi device connects through the extender to your router,
the MAC address of the WiFi device shown on the router is translated to
another MAC address. If your router's MAC filter, WiFi access control, or
ACL is enabled, the WiFi device connects to the extender but cannot get
an IP address from the extender and cannot access the Internet.
To allow the WiFi device to receive an IP address from the extender and
access the Internet, you must provide the translated MAC address to the
router.
