Network intrusion please help

[RickyRay]

I'm running the Linksys wrt54g wireless router on my cable modem. I've set it to 128 bit WEP encryption, disabled the broadcast radio, and enabled MAC filtering to only permit certain MAC addresses access on my router.

When I check the status of the router the other day I noticed that there is a MAC address that is accessing my network that is not on my allowed list. How is this possible?

Since then I've changed the SSID name on the wireless network and also generated a new WEP encryption key. Is there anything else I can do to make my network more secure at home and prevent further intrusion?

If the wireless adapters in your computers allow it, switch to WPA encryption. WEP is very easy to break and MAC address filtering can be defeated easily as well.

There's your problem.

How is 128 bit WEP Encryption the problem???

The router does have the capability for WPA, I will look into that and see how to set it up.

Wep is not secure these days, as you've already found out.

With routers so cheap it might be in your best interest to get one that supports WPA2.
