How to Setup a Wireless Network

Pre-requisites: You will need a working Broadband Connection; Wireless Router;  Computers with Wireless Network Adapters; and other wireless network devices such as Smart Phones, iPad, wireless printer, Gaming Console (eg…PS3, Xbox), Smart TV, Roku Box, etc.

In this Tutorial,  we will use a Linksys Router. The procedure may vary depending on the Model of your Linskys Router but it will be similar. Other routers such as D-Link, Belkin, Netgear, etc. will have similar features. Installation CD is not required in this process, this is a manual process.

List of Default Router’s IP and Admin Passwords:

Connect a patch network cable between the Modem output port and the Router’s WAN or Internet Port.  Connect a patch network cable (also called an Ethernet cable ) from one of the router’s LAN or Ethernet Ports to each device that will use a wired connection. Keep an eye on the Modem and Router’s lights until they are stabilized. You may need to do a Power Cycle just in case you can’t access the Router’s IP Address.
Note:  Crossover network cable is not required if your router supports Auto-negotiation.

While your computer is connected to the router, open up a browser (IE, Chrome, Firefox) and type, this will prompt you for a User Name and Password, The default User Name (for most of the Linksys Routers) is admin, default Password is admin. It is advisable to change the User Name and Password for security purpose.

In the Basic Setup page, verify that DHCP is enabled and that there are at least 50 DHCP Users.

In the Administration Tab you may change the Router’s password (do not use the default password for security reason).

In the Wireless Tab, then Basic Wireless Settings, change the SSID or wireless network, make sure not use your Router’s Name.

In the Wireless Security Tab, you may setup your wireless network encryption.  It is recommended to use WPA2, then type in the Shared key (also known as security/ encryption key or pass-phrase) of your choice and make a note of it because you will apply the same Shared key on all your wireless devices that need to be connected to this router. If, for some reason that other wireless devices can’t connect to your router, you may change the wireless security in Security Mode, try not to use WEP because this is not secured at all.

I prefer to manually setup the Security Mode. Although, you may choose to use the Wi-Fi Protected Setup (WPS) to automatically set up your wireless security.

Other options that you may configure later on: Application Rules, Port-forwarding, Firewall Setting, Quality of Service (QoS) etc…..and all of these can be found in the Advanced Setting tab.

Now save all the settings.  In the WAN page of your router verify that you can see your ISP’s Public IP information and all of the settings that you have made. Once everything is verified, you have just completed configuring your router.

Your next task: Connecting all your wireless computers and devices to your wireless router. Ensure that you have the SSID and pass-phrase ready.

Log on to your Windows  7 and/or Vista wireless computers andclick on the network icon or  in the notification area. Choose your own SSID or wireless network name (SSID must be broadcasting)  that appears on the connections available.

Log on to your Windows XP wireless computers and connect to your SSID.  As you can see in this image the wireless network connection properties is different than Windows 7 and Vista.
 Click Connect to your SSID and it should prompt you for the Security key, make sure to correctly type it in. You should now see that your computer is connected to your wireless network.

Now that you have a wireless home network setup, it is recommended that all computers have Firewall enabled. The Windows built-in Firewall is a good protection. Anti-Virus and Anti-Spyware/Anti-Malware Software must be installed as well.

Also, if you’re having a minor networking issue such as disconnection after all of the above configurations, a Power Cycle might help. If, for some reason your wireless connection doesn’t work, depending on your ISP, you might need to enable Mac Cloning. This option is visible in your router setting.

Note: Don’t forget to connect the rest of your wireless devices such as Smart Phones (IPhone, Blackberry and Android) wireless NAS, wireless Printers and gaming consoles to your wireless network.

How to Setup a D-Link Router

In this Tutorial we will be using a D-Link DIR 655 wireless router connected to a Charter Communications Cable Modem. We will not be using the D-Link installation CD but will manually configure your router.

To begin, connect a patch network cable between the Modem’s port and the Router’s WAN or Internet Port. Connect a patch network cable from one of the router’s LAN or Ethernet Ports to each device that will use a wired connection. Keep an eye on the Modem and Router’s lights until they are stabilized.

From a computer wired directly to the router, open up your favorite browser and type in Type the Default User Name of admin and the Password is blank.

Note: You may have to do a Power Cycle in case that you can’t access the router’s configuration page.

In the Tools Tab, change the Admin Password right away for security reason, do not use the default D-Link Admin Password.

In the Setup Tab you may either select the Internet Connection Setup Wizard or Manual Internet Connection.

In this Tutorial we will select the Manual Internet Connection option. In the Internet Connection Type we will use Dynamic IP (DHCP).

To configure the Wireless Security – Click on the Setup Tab, then Wireless Settings Tab. In here, you may choose to manually setup your wireless network or use the a Wi-Fi Protected Setup (WPS). Let’s choose the Manual Wireless Connection Setup.

Click on the Manual Wireless Network Setup, type your SSID (wireless network name) make sure that you do not use your router’s name (default SSID). You may leave the Mode to the default which is the Mixed Mode. You may change this later on if you’re having any wireless issues. Save the setting after the changes.

In the Wireless Security Mode, it is recommended to use WPA2. If some of your wireless devices don’t support this mode, feel free to change it but please do not use a WEP Security (not unless some of your wireless devices won’t connect to WPA2) bec. it is equivalent to a No Security. We will choose WPA2 TKIP and AES and type in a complex password but easy for you to remember. Save the setting after the changes.

Take advantage of the great features in your D-Link router such as Quality of Service (QoS), Port forwarding and Guest Zone. The Guest Zone is one of the nice feature of D-Link DIR 655 and not all routers have this type of option. If you enable this feature, you may create a separate SSID (or wireless network) other than your own SSID for Guests use only and have them connect to a separate SSID and isolate your Guests from your own wireless network for security reason.

To setup Port Forwarding, go to Advanced Tab, then Port Forwarding Tab. Make sure that you have all the Port Numbers handy for the Applications that you need to be port forwarded. Add the Application Name, TCP & UDP Ports Numbers and Schedule. Save the setting after the changes.


Mac Cloning – You will need to enable Mac Cloning from Dynamic IP (DHCP) Internet Type section and click on Clone your PCs MAC Address if your ISP didn’t provide you with your IP information. If you are not sure about this you may contact your ISP.

You don’t have to do anything at this point if it’s not needed.

We have just concluded setting up a D-Link DIR 655 Router. Feel free to take advantage of the Support Menu just in case that you have any concerns regarding your router setting. It is located in the Support Tab. There are a few helpful information that you may utilize.

Finally, you may now connect all your wireless computers and devices (smart phones, printer, gaming console, etc.). Make sure to type in the correct pass-phrase to ensure a successful wireless connectivity. If you encounter any disconnection issues on your wired and wireless network devices, you may do a Power Cycle.

Setting up an AP or Client Bridge Router Behind a Firewall or Security Appliance

This Tutorial can be utilized in a business network environment. This is based on my knowledge on how to configure a Buffalo AP (Access Points)/Bridge Router (other Brand and Model of AP/Bridge Routers may have some similar features) that’s connected behind a Sonicwall TZ 210 or any Firewall/Security Appliance. An installation CD is not required in this entire Tutorial, please leave it up to me to guide you.

Pre-requisites: A broadband connection, A Windows Server 2003 and above (best to use a Windows 2008 Server R2) configured with Dynamic Host configuration Protocol (DHCP) and Domain Name System (DNS), a Security or Firewall Appliance, an AP/Bridge Wireless Router capable (we will use a Buffalo AP/Bridge in this Tutorial), wired computers, wireless computers and other wireless devices such as IPad, Tablets & Smart Phones.

Additional information: Your Firewall or Security Appliance must have the Network Address Translation (NAT) enabled. Make sure that DHCP is disabled from your Firewall/Security Appliance.

Make a note of the existing Subnet of your network, for example: 192.168.1.X which we will be using in this Tutorial. Also, write the IP Address, Subnet, Gateway and DNS Server that you will be going to assign in the LAN configuration of your Router. Note that the Gateway will be your router’s new IP Address.

Note: The network cables that are connected from the Modem and Network Switch to the Sonicwall’s WAN and LAN Ports will remain untouchable in this entire tutorial. It is important to remember not to disconnect or unplug any of these network cables.

To begin, connect the power cable into the Buffalo Router, wait for the lights to stabilize. Connect a patch network cable from the WAN or Internet Port of the Router to the Sonicwall Port (X2, X3 etc.). Connect another patch network cable coming from a computer to another open ethernet port (X2 or X3) of the Sonicwall device.

While your computer is connected directly to the Sonicwall device, modify the Local Area Network (LAN) setting. In this guide, we will be using the network subnet of 192.168.11.X (Buffalo’s Router Subnet).
In Windows 7 and Vista – Click on the Start button type ncpa.cpl then press enter to open up the Local Area Connection screen. Double click on Local Area Connection, then click on Properties, double-click Internet Protocol Version 4 (TCP/IP v4).

In Windows XP – Click on Start, type ncpa.cpl then press enter to open up the Local Area Connection screen.
Double click on Local Area Connection, then click on Properties, double-click on Internet Protocol Version 4 (TCP/IP v4).
Type the IP Address, Subnet Mask, Default Gateway and DNS Server of your Network. In this tutorial we will assign an IP Address of, Subnet Mask of and a Default gateway of Leave the DNS Servers empty.


Open up a browser from your computer and type the Buffalo Router’s default IP of, it will prompt you to change the default User Name and Password, just in case you will need to enter the default.
Username: admin
Password: password

Make sure to use a complex password. Think of a combination letters, numbers and symbols for your router’s new password but easier for you to remember.

In the Basic Setup Tab Disable the WAN Connection Type.

In the Network Settings Tab, go to Network Setup, type in the Router’s New IP,  Subnet Mask, Gateway and Local DNS for example Remember, this is from your network’s current Subnet configuration.  Make sure to disable DHCP to avoid any conflicts and verify that DHCP is enabled in your Windows Server.

In the Wireless Tab, then Basic Settings, you may choose if you’d like to setup your Router as an AP (Access Points) or Client Bridge. I’d prefer a Client Bridge for a greater wireless coverage. Select Client Bridge (Router).

Assign an SSID for your wireless network. Do not use your Router’s Name.

You may manually or use Wi-Fi Protected Setup (WPS) to secure your wireless network by using WPA2, do not use any network security lower than WPA2, you do not want your wireless network to be vulnerable from outside unseen malicious objects and threats. You may auto generate the pass-phrase or manually assign a complex password for your wireless network.

In the Security page, verify that the Firewall is Enabled.

Save all the settings.

Important Notes: Some ISPs may require a MAC Cloning. You will need to contact your ISP regarding this. To do this, go to Setup, then MAC Address Clone, then enable.

Change the LAN’s setting of your computer back to Obtain an Auto IP address automatically. Go to Control Panel>Network and Internet>Network and Sharing Center>Local Area Connection.

Unplug the network cable from the Buffalo Router’s WAN Port and unplug the network cable coming from the Sonicwall’s X2 or X3 Port. Unplug the power cable from the Buffalo router and wait for 30 seconds, then plug the power cable back again, wait for all the lights to stabilize. Now, connect the network cable to the Sonicwall’s X2 or X3 Port and connect the other end into the LAN Port of the Buffalo Router. You may now connect all your wireless devices to your new SSID (wireless network name), make sure that you have the proper pass-phrase typed in.

Open up your browser from any of your computers (wired and wireless) and see if you’re able to log on to your router using the new Router’s IP which in this Tutorial we assigned a 192.168.1.X. You may enable or modify other great features of your new router.

I hope that this Tutorial helped you connect an AP/Bridge Router into your Security or Firewall Appliance. Utilize the great features of your new router if you have them, for example the NAS, Guest Zone and FTP would be great to have.
