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?

Oh yes ..read here Non-Broadcast Wireless SSIDs Why hidden wireless networks are a bad idea - Microsoft Enterprise Networking Team - Site Home - TechNet Blogs

Mac filtering is just an added layer..



True anything can be broken ,even with wpa2 encryption if someone is foolish enough to use a common dictionary word. but any aplhanum passkey above 20 characters will take months to crack on a standard computer unless u have supercomputer like watson

I'm sorry..we are talking about a "Phase Shift Keying" type key here...not some pseudorandom key..which can take months...

psk stands for pre shared key Pre-shared key - Wikipedia, the free encyclopedia..which is the passphrase one uses to access the network.

Is this setup secure ..wanted to enable wpa2-enterprise but looks complicated so this is probably the next best thing
1) WPA2-PSK with 50 key alphanumeric pass key
2) changed default ssid
3) changed admin account password
4) mac filter
have purposely not disable ssid broadcast ( read a technet article that says turning off ssid broadcast does actually more harm than good since paired network devices are always searching for the particular hidden ssid thus in turn exposing themselves)

There a few tools like aircrack etc which claims to break wpa2 encryption but that maybe because of a weak passkey or do they use some other technique? else breaking any passkey above 20 keys is not possible using standard computers/laptops.

What I meant was if it was that easy with just a few clicks then the wifi router business would have flopped by now.

So indeed with a complicated pass key..breaking into a wpa2 wifi network is no childs play

do u mean by bruteforce or some other method.
