Hi.

Got my htpc all finished today, installed vista (for now!!) but im having some probs regarding my network security. Im a total noob a t networks so bear with me:p

Heres how i have it all set up atm. Virgin router ethernet is plugged into my netgear wireless g and my main pc and htpc plugged into the wireless g.

Heres the problem though. As my Sky will be going off this weekend i thought it best to get the gf's laptop connected to the virgin wireless. So when i checked through available networks the virgin showed up, thing is its unsecure:o. I tried the routerlogin thing and messsed around there, but it still shows up unsecure. As i said im a complete noob at this so any one who can help me gets +100,000,000 rep points:D

Cheers!

You have to enable wep and make a authentication key and then use that as a passkey

You've got a virgin cable modem plugged into your netgear wireless router? All fairly standard. If you've enabled WEP and restarted your router and its still showing as unsecure, could it be a neighbours you are detecting?

Would be quite funny if he "secures" a neighbours wireless. :D


Should find a page like below under "wireless settings"

Change it to WEP and give yourself a password. Hit apply and it should work straight away.

Also will be worth you changing the login password for the router...as most are one of a few possibilities and easily guessed

Wasnt my neighbours lol, im not that much of a noob:p But would of been funny if i hacked a neighbours net, not that i condone that sort of stuff *ahem*:)

Anyway its sorted now. In the available networks it was showing up as 'virgin'. I forgot to enable SSID broadcast and when i enabled it in the network list it showed up as my network name secured :)

Thanks for your help;)

Do *not* use WEP -- seriously insecure.

Use WPA at a minimum with a strong alphanumeric passphrase, disable SSID broadcast and if you're seriously paranoid allow only trusted MAC clients to connect to your router/access point.

Obviously that's your prerogative but I think of it akin to leaving your front door key under your doormat. From wikipedia --

In 2005, a group from the U.S. Federal Bureau of Investigation gave a demonstration where they cracked a WEP-protected network in 3 minutes using publicly available tools.


If your access point was made in the last 4 years or so it's almost guaranteed to support WPA encryption, so why not make use of it?

As already said above WEP is pants, script kiddie tools do that in 10 minutes.

WPA2 with 256bit AES encryption is the way forward.

+1 on security but watch out for performance, lot of routers performance just die when using WPA2 with 256bit AES because they don't have strong enough CPU

The performance will depend on how many people are connected to it.
I'd say most routers would be able to run at their rated speed with a reasonable number of people connected.
My low-mid range Netgear router is fine for 100Mbps transfers with an additional 6 wifi connections on WPA2.

Just disabling broadcast of the SSID is a good start to securing the WiFi. That and changing the default name. WPA is obviously good stuff. Sometimes people get put off because the encryption chews up the performance of the network. In that case, I'd step back and decide whats most important: copper cables will be faster AND secure (they just arnt as neat).

Yeah do not use WEP at all, takes me 3 mins max to crack it on my router. And for the allowed MAC address list, some one can spoof the MAC address to match the one on your pc and join the network.

we use a certificate at home through a smoothwall box, then to the tinterweb... pretty secure :)
