The 3com 3CRWER100-75 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.
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.

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.
Encryption
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 3com 3CRWER100-75
To get started configuring the 3com 3CRWER100-75 WiFi settings you need to login to your router. If you are already logged in you can skip this step.
To login to the 3com 3CRWER100-75, follow our 3com 3CRWER100-75 Login Guide.
Find the WiFi Settings on the 3com 3CRWER100-75
If you followed our login guide above then you should see this screen.
You begin on the Welcome page of the 3Com 3CRWER100-75 router. To configure your WiFi settings, click the option on the left labeled Wireless Settings. Then, looking at the top of the page click Configuration.
Change the WiFi Settings on the 3com 3CRWER100-75
Your Enable Wireless Networking should be on by default. If you see that it is not marked, go ahead and check this small box.
Next is the Wireless Mode. Choose Mixed.
Below that is the Channel Selection. In the United States the three channels that should always be used are 1,6, and 11. For more information on why you should only use these three channels check out our guide on WiFi channels.
Then, in the box labeled Service Area Name/SSID there are two different things you can do. The first is enter the wireless name in the box labeled Service Area Name/SSID. This is the name of your network. Don't include any personal information here. We have a great guide on the subject if you want to know more about wireless names. The second option in this box is Enable Broadcast SSID. By default this should be Enabled. If you want to broadcast your SSID or network name, your network is visible to all the surrounding networks. If you want to keep your SSID hidden, it is invisible to the general public but not to a scanning tool used by hackers.
When you are finished with these changes, go ahead and click Apply.
You need to choose the type of security encryption to use. Click the option on the top of the page labeled Encryption.
You should now be on a page that looks like the one you see above.
There is only one option available on this page. The Security Mode is a very important security feature that shouldn't be overlooked. Use this drop down menu to choose WPA2 Pre-Shared Key. WPA2 is the strongest encryption available today. For more information on the different choices check out our WEP vs. WPA guide.
At this point, a new box should appear asking for a Pre-Shared Key. This is referring to the network password. This is extremely important for your network security. Make sure that this password contains no personal information, or any word you can find in a dictionary. Do use symbols, numbers, and capital letters. For more help in creating a strong password check out our creating a strong password guide.
That's it, you did it!
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.
