Your EW2104 router is the hub of your internet providing Wi-Fi Network. Without your router, you would not be able to stream series, play games online, or even browse the web. However, you can't just buy a EW2104 router and expect the internet from out of the box. There are steps you need to take before you get up and running:
If you have plugged your router into the power and internet, and all the indicator lights show that it is working, you are halfway to having an internet-capable Wi-Fi network. The next step is setting up that same Wi-Fi network, along with configuring other settings of your EW2104 router. All of these settings get changed in the router's interface.
The login details for your router's interface are a bit too easy to find, and that is because router manufacturers use the same details for all of their routers. Anyone can access your router's interface, so the first thing you should do is change those details. With the router interface open, search for general settings, network admin, or a similarly named menu. In this menu, you can change the login details, though, make sure the new details are secure and that you can remember them.
With the actual Argus Technologies EW2104 router unit secure, you should turn your attention to the Wi-Fi network it provides. In the router interface, you need to find the menu titled wireless security, or similar. In this menu, you can set a security scheme for your router, which will usually be one of the following:
WPA2 is the current standard and the most secure, though some devices will not connect to a Wi-Fi network using this scheme. Some routers come with multiple networks, which helps overcome this compatibility issue. After you select a Wi-Fi network security scheme, you will receive a prompt to enter a password. Again, make sure you can remember it and that it is secure.
While changing the Wi-Fi network password, you might also change the name or SSID of the network. Doing so is only cosmetic, though it can help you differentiate your network from others if you live in a busy area. While in the interface of your EW2104 router, search through the general settings menu until you find the SSID field. In this field, input your desired Wi-Fi network name.
You need to enter the IP address of your router into a web browser to access the router's interface. You wouldn't be alone in thinking that the chain of numbers gets used solely for that purpose. However, the private IP address of your router is much more than a website address. The four numbers separated by periods act as an address that allows connected computer devices to communicate with the router. Without an IP address, your router would not be able to receive data requests from your computer, which would leave you without internet access. You can find the IP address on the base of the EW2104 router by Argus Technologies, though if you have brought a router second hand, without a bottom label or manual, how can you find the IP address? Well you can check online, or you can use your computer to check another way:
Your Argus Technologies EW2104 router has two IP addresses. The private IP address mentioned previously only affects your home network. All of your computer devices connect to the router using the private IP address, and those same computers each have there own IP address, so your router knows where to send requested information from the internet. Once your router receives that request from a computer connected to the Wi-Fi network, it passes it over to its public IP address.
Unlike your private IP address, your public IP can get seen by the outside world. Websites use your router's public IP address to send the requested information back to your router via your ISP. Unlike a private IP address, no two routers have the same public IP address, and your public IP can change from time to time as there are only so many numbers that can get used for this function. This act is called a dynamic IP. You can find out your current public IP address by searching 'what is my IP address' on Google.
