WiFi Terms

Before we get started there is a little bit of background info that you should be familiar with.

Wireless Name

Your wireless network needs to have a name to uniquely identify it from other wireless networks. If you are not sure what this means we have a guide explaining what a wireless name is that you can read for more information.

Wireless Password

An important part of securing your wireless network is choosing a strong password.

Wireless Channel

Picking a WiFi channel is not always a simple task. Be sure to read about WiFi channels before making the choice.


You should almost definitely pick WPA2 for your networks encryption. If you are unsure, be sure to read our WEP vs WPA guide first.

Login To The NetComm 3G42W-MB

To get started configuring the NetComm 3G42W-MB WiFi settings you need to login to your router. If you are already logged in you can skip this step.

To login to the NetComm 3G42W-MB, follow our NetComm 3G42W-MB Login Guide.

Find the WiFi Settings on the NetComm 3G42W-MB

If you followed our login guide above then you should see this screen.

You begin on the Basic > Home page of the NetComm 3G42W-MB router. To configure the WiFi settings, click the option at the top of the page labeled WIFI. Then in the box that appears, click Setup.

Change the WiFi Settings on the NetComm 3G42W-MB

This brings you to the page you see here. Find the box titled SSID. This is the name you create in order to identify your network. While it really doesn't matter what you enter here we recommend staying away from personal information. Click this link to learn more about the SSID.

Once this is done, click the Apply/Save button.

Now click WIFI at the top of the page once more and choose the option of Configuration in the blue menu that appears.

There are a lot of different setting on this page. The only one we are interested in right now is called the Channel. If you have neighbors there is a possibility your channels are interfering with each other. Partially overlapping channels cause a great deal of interference. However if you completely share a channel there is not nearly as much interference due to channel sharing software built into routers. There is only room in the channel spectrum for up to three channels that don't overlap at all. We recommend that everyone use one of these three channels, they are channels 1,6, and 11. Click this link to learn more about your WiFi channels.

Click Apply/Save if you made any changes on this page.

Go back to the top of the page and open the WIFI menu. Choose the option of Security.

The upper half of this page is dealing with WPS. We don't recommend the use of WPS, as it is an easy way in for a network intruder. Disable all the WPS options on this page. Click this link to learn more about WPS.

Scroll down this page until you come to the heading of Manual Setup AP. Use the first drop down list under this heading called Select SSID to choose the SSID or network name you just created.

Under that is the Network Authentication. This is the security you will be using for your local internet. We recommend WPA2-PSK. Find out why in our WEP vs. WPA guide.

Now locate the box titled WPA Pre-Shared Key. This is the internet password. It is also used with the encryption so it really should be strong. Our recommendation is to use a minimum of 14-20 characters and at least one number, symbol, and capital letter. Click this link to learn more password strengthening ideas.

The last setting that can be changed on this page is called WPA Encryption. The best encryption for home networks is AES.

That's it, you have made your network more secure. Don't forget to click the Apply/Save button before you exit.

Possible Problems when Changing your WiFi Settings

After making these changes to your router you will almost definitely have to reconnect any previously connected devices. This is usually done at the device itself and not at your computer.
