Simple Wireless Security Question

Recommended Posts

I simply want to put a password on my wireless router so jackholes can't drive up in a dark van and download kiddie porn using my bandwidth.

 

I have SSID broadcast disabled, but I also want a password before someone can connect to my router. Is this the WEP Key field I see in my router's setup page?

 

I tried using that, and it generated 4 keys using a "passphrase" that I typed in. Then I went back to my laptop (which now didn't let me log on without a Network passcode) and I tyed in either the passphrase or a key. No luck.

 

Help!

 

Thanks

WEP only encrypts the data that passes over your wireless network. It doesn't do anything as far as someone logging into your router. You should have to type in a username and password to get into the router by default. Is this what you mean?

Yes, I do have to type user name/ pass to get into router's settings page.

 

I want a password to log on using a laptop. I.e. I want a password that you must type in before you can use the internet on your laptop, using my wireless signal.

I'm not sure that is possible. If you want to restrict people from using your wireless internet connection I would recommend MAC address authentication.

I'm clueless.

 

Can you explain how to do that please?

Sure, each piece of networking equipment that exists has a MAC address associated with it. You can think of it as a fingerprint for networking equipment, no two of them are the same. They are in the form of XX:XX:XX:XX:XX:XX. The ethernet card in your computer has one, your xbox has one, a wireless card in your laptop has one. In your router settings, you can specify MAC address authentication, which means that only the MAC addresses you specify will be able to join your wireless network.

 

To get the MAC address of your ethernet card in your computer, you need to go to the MS-DOS prompt and type in "ipconfig /all". It will display your ethernet adapters MAC address (I think it is called "physical address"). Put this in your router's config, along with all the other MAC addresses that you will allow to connect to your network. MAC addresses for the xbox and wireless cards can usually be found on the back of the card or the bottom of the xbox. The MAC address for the xbox can also be found in the live settings in the dashboard I believe.

 

If you need anymore help please let me know.

Thank you, Paul! I'll give that a try.

 

However, are MAC Addresses unique to each device? Something in the back of my mind tells me I've done something before that implied my laptop's wireless mac address changed regularly... hmm...

Every single device has a different MAC address. If you have 3 different wireless cards you use in you laptop you need to put in all 3 of those MAC addresses. They will all be different.

Yep, it's possible. MAC address filtering is a stronger protection, but WEP is widely used to govern access to a wireless network, and it's a good idea to get it working. The initial problem may have been a different in WEP bit levels, or a confusion between "passphrase" and "string" entry of the WEP key:

 

? 40 or 64 bit ASCII WEP code has 5 characters

? 40 or 64 bit HEX WEP code has 10 characters

? 128 bit ASCII WEP code has 13 characters

? 128 bit HEX WEP code has 26 characters

 

For info on WEP troubleshooting, check out Wireless Encryption Help. For more guidelines on wireless security, check out Securing your Wireless Network

 

Practically Networked is a great site for info.

Something is not making sense.

 

In my Linksys router's setup page, I found "Mac Filter Settings" under the "Filters" tab of the Advanced section.

 

However, at the top of the Filters section, I saw this: "Filters enable you to prevent certain PCs on your network from accessing your Internet connection. "

 

I added one of my PCs to the filter list, and sure enough, it could no longer access the internet.

 

I can't find an option to do the inverse - i.e., have ONLY Filtered PCs gain access. :?

That won't do you much good since the whole premise is that you won't know the MAC addresses of people that are trying to get on your network.

 

I wish I could help, but I have a D-link router and it's setup is obviously not the same as the Linksys. Keep searching, there should be something there.
