LED descriptions

Conﬁgure a router with

advanced MAC settings

to work with your extender

If you enabled a WiFi MAC filter, WiFi access control,

or access control list (ACL) on your router, when a 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.

To add a translated MAC address to your router

and reserve an IP address for your extender:

1. Log in to your router and disable the MAC filter,

WiFi access control, or ACL.

For more information about how to disable your

router’s MAC filter, WiFi access control, or ACL,

see your router’s documentation.

2. Power on the extender and connect all of your

WiFi devices to the extender.

3. Make sure that the Router Link LED remains lit.

4. Log in to your extender:

a. Launch a web browser from a computer

or mobile device that is connected to your

extender network.

b. Log in to your extender:

• If you did not enable the One WiFi Name

feature, enter www.mywiﬁext.net in the

address ﬁeld of the browser.

• If you enabled the One WiFi Name feature,

enter one of the following URLs:

‑ Windows-based computer.

http://mywifiext.local/ or

http://mywifiext/

‑ Mac computers and iOS devices.

http://mywifiext.local/

‑ Android devices.

http://<extender’s IP address>/ (for

example, http://192.168.1.3/)

A login page displays.

c. Enter your admin user name and password

and click the LOG IN button.

The Status page displays.

5. Select Settings > Connected Devices.

The Connected Devices page displays the

MAC addresses and virtual MAC addresses for

computers and WiFi devices that are connected to

the extender network.

6. On the router, add all of the extender’s virtual

MAC addresses and all of the virtual MAC

addresses of the devices connected to the

extender to your router’s MAC ﬁlter table.

Note: To reserve a specific IP address for the

extender, you must specify the first virtual MAC

address that displays for your extender’s 2.4 GHz

or 5 GHz network in your router’s IP reservation

table. (The first virtual MAC address that displays

for your extender’s 2.4 GHz and 5 GHz networks is

the same.)

7. Enable the router’s MAC filter, WiFi access control,

or ACL.
