Netgear EX3700 Setup Instructions, How To




These Netgear EX3700 setup instructions for this Netgear® AC750 WiFi range extender model EX3700, show easy itself; especially when you have screen shots from an actual setup scenario, as we snapped here, while connecting our EX3700  to our existing wireless networks.



The Netgear® firmware automates much of the procedure in the Genie wizard web interface at the netgear extender setup website as you’ll see below, so that nearly all you need do is answer a few questions; most of which they supply with acceptable default values.  Then, you find your networks to be extended in a list they provide, enter their passwords, and this wireless extender takes it from there.  The Netgear EX3700 connects to your selected wireless networks and repeats them; extending their range as advertised.

The picture above shows the Wi-Fi range extender after Netgear EX3700 setup, connected to and extending both our 2.4 Ghz. and 5 Ghz. wireless networks.  The router  lamp on the top left corner in this picture, glows a solid green, indicating that this device is receiving good signal from the primary network(s) previously programmed into it, and repeating them successfully.  The power LED indicates that the unit is powered on; normal operation is denoted by, again, a steady green glow.

The WPS lamp also glows, meaning that Wi-Fi protected setup is available (this light flashes when a WPS-based authentication is in progress).

Finally, the device lamp, which is off in the above picture, glows when you connect a wireless device to one of the networks hosted by this range extender.

Now in this procedure, we’re going to wipe the Netgear EX3700 clean of any user-programmed settings, and show you how to set it up to extend the networks in your particular environment.



Netgear EX3700 Setup Procedure

1. Connect the Netgear EX3700 to Power

As shown above, you just plug it into a standard wall outlet.  Do this in the same room as your primary router.  While doing Netgear EX3700 setup, this extender needs to be close to your primary Wi-Fi networks.  However, once you’ve completed setup, you can then move the EX3700 to anywhere within range of your primary wireless network that need improved Wi-Fi network reception.

2. Reset the Netgear EX3700 to Default Factory Setting Before Netgear EX3700 Setup

Jump ahead to step 3 if you purchased this extender brand new.
However, you’ll want to RESET this device if you bought a used one, just in case the seller did not clear out their customizations.  Press the RESET button for ten seconds, located on the left side of the unit.  The power light will blink yellow a few times, indicating that a reboot is in progress.
The reset has completed successfully when the power light glows that steady green, as shown next.  Note that after a reset, neither the router nor device lamps should be glowing, as the Netgear EX3700 has not yet connected to any routers or client devices.

3. Log into the Netgear Extender Setup Website to Configure the EX3700

Then, go to your computer or mobile device and scan for the “NETGEAR_EXT” wireless  network.  We found it on our iPad Air, as pictured next.  This access point is only active during Netgear EX3700 setup, and will go away once you’ve finished setup.

Next, join the NETGEAR_EXT network.  Since it is OPEN, you will not be prompted for a password.  For example, on our iPad Air, we join it simply by single-tapping it.  Upon connection, our tablet was assigned the IP address 192.168.1.129.
Once connected, the Netgear extender setup website (Netgear Genie Setup) front page comes up automatically,  as shown next.  If this startup page does not appear within a few seconds of connecting, then head to your favorite browser the visit the site http://mywifiext.net/ .

4. Tap the  New Extender Setup  Button

This brings up the new account creations screen as follows.

5.  Enter New Account Information 

The Netgear extender setup wizard then prompts you for an email address, new account password, new account password confirmation, and two security questions.  You can choose what each security question is from lists, and then enter the answer for each. Fill out this screen accordingly.

6. Tap the blue    Next   Button

This brings up a screen that asks you how you wish to utilize your EX3700; you can use this Wi-Fi extender as an extender, or as a wireless access point.  We’re not going to cover the WAP option here.

7. Tap the  Wi-Fi Range Extender  Button

Find the WiFi range extender button, pointed at by the pink arrow in the previous picture.  This tells the Netgear EX3700 to scan both the 2.4 and 5 Ghz. bands for eligible wireless networks to repeat, and thus, extend.

Next, after a short pause, the netgear extension setup wizard shows the “Choose the wireless network you’d like to extend” screen, as pictured in the next step.

8. Pick the Wi-Fi Networks you Wish to Extend

Notice in the last picture. See the radio buttons to the left of each wireless network, found when the extender scanned for them.
In this example of Netgear range extender EX3700 setup, the EX3700 found Wi-Fi networks in both the 2.4 Ghz. and 5 Ghz. bands.  So, check either or both of these, depending on which band  you want to extend.  If you wish to extend a 2.4 Ghz network, but not a 5 Ghz. one, then check the 2.4 Ghz. Wi-Fi Networks checkbox, and uncheck the 5 Ghz. Wi-Fi Networks checkbox.  Or, if you want to extend a 5 Ghz. network, but not a 2.4 Ghz. one, then check the reverse.  That is, tap the 5 Ghz. Wi-Fi Networks checkbox, and uncheck the 2.4 Ghz. Wi-Fi Networks checkbox. Or, finally, in the case where you’re hoping to extend both 2.4 and 5 Ghz. networks, be sure to check both boxes.  In our scenario here, we’re extending both network types, and so we have both check boxes marked in the previous picture.
Then, for each network band, tap the Wi-Fi network in that band you want to extend.  In our case, in the 2.4 Ghz. networks list, we’re going to extend the 937T681J4059H_2G network, and in the 5 Ghz. networks list, we’re extending the 937T681J4059H_5G network. As highlighted by the pink lines in the previous picture, we’ve selected those networks, as shown in the next picture.

9. Tap the blue   Next   Button

This then prompts you for the 2.4 Ghz. and 5 Ghz. wireless network passwords, as shown next.

10. Enter Network Security Key (password) for One or Both Wi-Fi Networks

Next, enter the password for the 2.4 Ghz. wireless network you’re extending.  Then, enter the password for the 5 Ghz. network.

11. Tap the Blue   Next   Button

During Netgear EX3700 setup, the extender then tries to connect to the wireless network(s) you’ve chosen.

Then after a short pause, and if all goes well, the EX3700 successfully connects to the primary wireless networks being extended.  Netgear EX3700 setup is just about done.

Next, Genie® then prompts you, as shown in the next picture.  Further, she offers you to edit the network names and passwords for the new extension networks.  There’s now one new network that the extender has created for your 2.4 Ghz. primary Wi-Fi network.  Also, there’s one for the 5 Ghz. Wi-Fi network.

Furthermore, by default, these take the same as your primary networks with slight additions.  The 2.4 Ghz. extension has a “_2GEXT” string appended to it. The 5 Ghz. extension network has  a “_5GEXT” string added to it.  Also, the extended network passwords default to the same passwords as the extended network passwords.  We suggest not changing from these default network names without good reason.

13. Tap the blue   Continue   Button

Then, this closes the Netgear® Genie® interface.

14. Scan for the Extended Networks

On our iPad, we again visit the Settings page, under the Wi-Fi settings, and we get the following screen.  The pink line circles the Wi-Fi networks broadcast by the EX3700 in the next picture.

15. Move the Netgear EX3700 to Where you Need improved Wi-Fi signal

Next, after Netgear EX3700 setup, unplug the extender.  Then, take it to the final location.  plug it in there, and wait for booting to finish.  The lights on its front should look as follows once the extender again establishes connection with your primary network.
