Wireless routers were designed to connect to more than one computer. A better question is how many devices can the model you have handle. According to most specifications the wireless routers should be able to handle up to 250 connections without fail. We all know that what works well in theory don't often work so well in actual practice.
Wireless routers are named for the function they perform, that is route network connection requests. One computer can conceivably make up to 50 request at a time. That is how they have come up with the magic number of 250, supposing that 5 computers were making the same 50 request at the same time. It is possible to run up to 10 computers from a single wireless router.
This means five computers only or three computers and two printers or any combination of devices as long as they total five. You can overload a system therefore it is not advisable to run five video game systems through the same wireless router. This will cause a traffic jam in the signals and slow everyone down considerably.
The hardware for this is your standard wireless router and a wireless adapter for each of the devices you are connecting. Most routers have at least 4 ports on them for Ethernet connection. Video game consoles mostly come with built in adapters, which makes them easier to connect. Laptops and notebooks generally require an external USB or a wireless network card.
To set the whole thing up you will need to start with your wired connection. Connect the wireless router to the computer through the land line connection. Run the installation software so that the system is configured to accept the wireless router's signal.
You should enter all of the security protocols at this time.
Now that you have the network up and running the rest of the connections will be much simpler. If there is an icon in the indicator tray on your system all you has to do is right click on it and open up the network manager. If not get there by opening the control panel from the start menu.
Once you have reached the network manager the only thing left for you to do is to select your network from the list on the drop leaf. Now you have the wireless router and your network set up. You have also completely installed the necessary security features, you may now design and enter your password or other settings that you are prompted to make. It is always smart to save your settings for future reference.
To expand your network even further you can eliminate the demands each computer makes on the wireless router. One way is to shut off plug-ins and tone down the fancy chat boxes. Go for simple and you can extend the range of your network. Reducing the total number of request from each system on your wireless network you have succeeded in making your network run smoother with less slow downs.
