When you buy a new pc or laptop, one of the first things to do is to manage your machine to communicate with a printer, a modem and finally with your wireless router. Sometimes to connect to the wireless takes longer and you may want to check first if your router’s firmware is up to date.
If your wireless connection is not going through, try to see if you can connect to your router with an Ethernet cable and log into the router’s interface to see if everything is working properly. If the router works properly, you may also want to check the signal range of your WI-FI: if you live in a large house or far from the wireless router, the router may have hard time finding your wireless device.
If you feel that it is time to replace the wireless router, try to shop for routers that have a beam forming technology, which aims to reach a wireless device instead of spreading the signal throughout the house. If even a powerful beam forming router does not help that much, try to complement the router with several range extenders that can be easily plugged on your wall outlet.
If, on the other hand, you are planning to build a new house or remodelling your apartment, you should ask your electrician to install several hard-wired access points on the ceiling, in order to have the strongest signal as possible. Bear in mind that, if you go this route, you should give a unique SSID to all the access points but a different channel to each of them to avoid frequencies overlapping.
In terms of security, after that you have set up your wireless network using a strong WPA2 password composed of at least 10 characters mixed with unconventional signs such as !@#%^&, you may want to consider enabling a wireless guest account for all those who do not have to know anything about your real network. If for example, your main wireless network starts with an IP range of 192.168.2.1 – 192.168.2.200, you may want to assign the guest network a different IP range, such as 192.168.6.1 – 192.168.6.200.
If you also run Windows on your machines, a good way to secure your wireless network is to change the DNS settings in your router first and then in the network card of your computer. Google DNS are easy to type in, but Open DNS does a better job by allowing your computer to be constantly updated every time your dynamic IP changes. Download the dynamic updater for Windows or Mac to see how it works after that you have opened an Open DNS account.
