I have changed from MTNL's wired modem to their wireless modem 450TC1. I do have a safe username and password set to avoid intruders but would like to get more security because I came across this website which mentions:
The first line of defense for your Wi-Fi network is encryption, which encodes the data transmitted between your PC and your wireless router. Unfortunately, most routers ship with encryption turned off, and many users don't turn it on, leaving themselves completely exposed. If you haven't already, enable your router's encryption, and use the strongest form supported by your network. The Wireless Protected Access (WPA) protocol and more recent WPA2 have supplanted the older and less-secure Wireless Encryption Protocol (WEP). Go with WPA or WPA2 if at all possible, since WEP is relatively easy to crack. (You have to use the same form on all devices on your network; you can't mix WEP and WPA.) The keys used by WPA and WPA2 change dynamically, which make them nearly impossible to hack.
So how do I know which protocol is the wifi using? Also, how do I set it up on all devices on my network as mentioned above?
