Manually setting up your Linksys RE4000W on a Mac OS X®

Mac users running OS X® 10.9, 10.10 and higher will have to use manual configuration to set up the Linksys RE4000W.

To set up your RE4000W manually, follow the instructions below.
Step 1:
Plug your range extender into an outlet near your computer and within the range of your wireless router.

Step 2:
When the range extender’s front light is solid, connect your computer, smartphone or tablet to the LinksysExtenderXXXXX wireless network.
NOTE:  The XXXXX in the wireless network name (SSID) is a series of alphanumeric characters.

Step 3:
Launch a web browser and enter “” in the Address bar.
Step 4:
A pop-up window will appear and prompt for authentication.  Enter “admin” for both Name and Password, and click the Log In button.

Step 5:
On the RE4000W’s web-based setup page, select the Wireless tab then select the Basic Wireless Settings sub-tab.

Step 6:
On the Configuration View section, select Manual.

Step 7:
Enter your network names for both 2.4 and 5 GHz frequencies.

Step 8:
On the Wireless Security section, select the Security Mode for each of your networks.

QUICK TIP:  If you forgot your Security Mode, select the Site Survey link on the Wireless tab.  You should see the Security Mode type listed next to your network name.  If your mode is listed as WPA-Personal; WPA2-Personal, choose WPA2/WPA Mixed Mode.

Step 9:
If your Security Mode requires a password, a password box will appear.  Enter the password for your networks.

NOTE:  If both networks have the same SSID, enter that name in both fields.  The range extender will connect to the 2.4 and 5 GHz bands.
Step 10:
Click  to configure your range extender.
NOTE:  A progress bar will appear.  Do not close the browser until the process is complete.

When finished, your RE4000W should be working.  You will be disconnected from the temporary network LinksysExtenderXXXXX.  You can now close your browser.
To confirm that you have successfully extended your network, unplug the RE4000W and move to a location halfway between the router and the area to which you hope to extend your Wi-Fi signal.  Use a computer or a smart device to be sure that you have at least 50% of your router’s wireless signal.  Open a browser to confirm that you are online.
If you cannot get online, the problem is probably one of the four (4) issues listed below:
  •  Wrong network name
  •  Wrong password
  •  Wrong security mode
  •  You are out of range of your router. 
QUICK TIP:  You may reset your range extender and perform the setup process again if you cannot get online. For instructions, click here.
