The 3com 3CRWDR101A-75 router is considered a wireless router because it offers WiFi connectivity. WiFi, or simply wireless, allows you to connect various devices to your router, such as wireless printers, smart televisions, and WiFi enabled smartphones.

Use a VPN Instead

Have you considered using a VPN instead of forwarding a port? For most users, a VPN is a much simpler and more secure choice than forwarding a port.

We use and recommend NordVPN because not only is it the fastest VPN, it includes a new feature called Meshnet that makes forwarding a port no longer necessary for most applications. With NordVPN Meshnet, you can connect to your devices from anywhere in the world, completely secure, over a highly encrypted VPN tunnel.

When shopping for a VPN, make sure that they meet the following criteria:

  • Your VPN provider should have a no-logs policy. This means that they do not keep any logs of any kind.
  • Make sure that your VPN provider has lots of exit nodes all around the world.
  • Check that your VPN will not affect your speed.
  • Verify that your VPN provider uses WireGuard as the underlying protocol.
  • Many people prefer a VPN provider that is not based in the United States.

This is the list of requirements that we used when we were shopping around for a VPN provider. There are lots of free, shady VPN providers out there that we looked at and dismissed.

Based in Panama, using diskless servers, and with over 6,100 servers in 61 countries, we can safely say that NordVPN satisfies all of these requirements.

NordVPN is the fastest VPN!

Once you've set up your NordVPN account on multiple computers and enabled Meshnet, you can seamlessly access all of your devices as if they were on the same network. You don't even have to log in to your router. It's very simple.

Every time you click on one of our affiliate links, such as NordVPN, we get a little kickback for introducing you to the service. Think of us as your VPN wingman.

This is the wifi setup page from your 3com 3CRWDR101A-75 router.

In the box labeled Wireless Settings use the drop down menu next to Channel to choose a channel. Pick either 1,6, or 11. For more information on why you should only use one of these three channels, look at our WiFi channels guide.

Below that is the SSID. This is the same as the network name. In this box, enter the name you want to use to identify your network from those around you. We recommend not using any personal information in this name. For a more detailed reason for changing your SSID, check out our wireless name guide.

The next option is the SSID Broadcast. By default this is Enabled. You are visible to the networks around you. If you choose to Disable the broadcast then you are invisible to the general public, but not to those who have the proper scanning tools.

Last on this page is the Wireless Mode. By default the choice of Mixed (11b+11g) should be chosen. This is the best choice.

You should now be on the page you see above. This page is very important to the security of your network.

The first drop down box is called WPA. From this menu choose the option of WPA-PSK (no server). The no server part is talking about a RADIUS server and as a home network you most likely don't have one of these.

Below that is the WPA mode. Choose WPA2. This is the most most secure encryption available today. For more information check out our guide on WEP vs. WPA.

Next is the Encryption technique. From this drop down menu, choose AES for both WPA and WPA2. Again if you need more information check out our WEP vs. WPA guide.

Then, in the box labeled Pre-Shared Key (PSK). Enter the password that you want to use to access your network. This password is very important for your security. Be sure to use symbols, numbers, and capital letters in your password. Don't use any personal information or any word from any dictionary. For more information on this check out our guide on how to choose a strong password.

That's it, click the Apply button when you are finished.

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.
