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?

In this modem/router all options are available.
Only in the modem WEP wpA etc are set.

In same page another option MAC filter is available.



You have to enable it and add the MAC address of ALL devices
Laptop/smartphone/printers etc for more security.

Can you please explain me where to do all this?

Hey guys, I found where to do all this. The authentication type is set to 'WPA-PSK' ...should I change it to WPA2-PSK?

Yes, change it to wpa2-psk

Okay, thanks, and what about TPIK/AES? It's set to 'TPIK/AES' but I read online that AES is the preferred one?

Is this setup secure ..wanted to enable wpa2-enterprise but looks complicated so this is probably the next best thing1) WPA2-PSK with 50 key alphanumeric pass key2) changed default ssid3) changed admin account password4) mac filterhave 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.

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..

there are tons of software out there which can crack your security..just by few clicks

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
