64bit WEP

Postby David Reiser » Tue Dec 18, 2007 11:20 am

I am able to connect via unlocked neighbors but not through our 64-bit WEP encrypted Linksys system. I had through this might be because the encryption is 64 rather than 128 bits (though that did not make a whole lot of sense), but I see from other posts that this may be a more general problem. What I can't quite tell is whether there is a readily available fix, so, at the risk of just repeating someone else's question, is there something I can do (other than disabling the encryption) to access our network. I saw a post suggesting that this could be done by putting in the XO MAC address, but I'm not sure I understood, or how to do it.
I'd appeciate any help, as I'm trying to figure things out before turning the laptop over to my daughter.

Hi David,

From what I've read there may be a fix http://lists.laptop.org/pipermail/community-support/2007-December/000057.html

As for the XO mac address:
Every wireless internet device has a unique MAC address. It's basically a unique ID that identifies the network internet card in that device. Think of it as a unique serial number.
Most wirless routers (like your Linksys access point) have a feature called MAC address filtering. So MAC address filtering is a way to tell your Linksys access point (it works with other brands as well) that you only want specific devices to be able to connect to your router. You would actually have to go to a configuration screen for your Linksys access point and type in the MAC address of every device you wanted to bea ble to connect to your wireless network.

If you did set up MAC filtering and I drove by your house with my computer and happened to know your WEP key (don't worry I don't have the slightest clue) then I would still not be able to connect to your wirless access point because your wirless access point wouldn't accept connections from my computers MAC address because you wouldn't have typed it in.


By default MAC filtering is not turned on in Linksys wireless access points. Thus they accept connections from any device and you are using WEP to make sure that only people that know the secret WEP code can connect. So unless you turned MAC filtering on, typing in your MAC address is not likely the problem.

Hope that helps.
Paul
