I have a linksys WRT54G running HyperWRT firmware. Do to the encryption limitations of some of my devices (TIVO, PDAs, etc.) I cannot use WPA encryption, and even WEP does not work all the time. This last week, I go everything working fine, but only by turning off encryption all together. I have also discovered someone else using my wireless network for Internet access and eating up a good deal of my bandwidth. So, i need to prevent others from getting onto my network, but I can't use the standard encryption methods to do so. Are there any other ways? Or should I just try and get WEP to work?

Usually you can lock it down by putting your devices in the mac address list , if the rogue address is not in your list he isn't going to far . Can he sniff the air and get around this , probably but most people don't know how or want to take the time .

I agree with vipergg. Every wireless device on my network appears in my MAC filtering list. Outsiders cannot connect because their "name" is not on the guest list. For most purposes, this is fine -- it keeps others from intentionally or unintentionally connecting to your network.

Of course, as vipergg said, there are ways around MAC filtering. But there are also ways around other types of wireless security as well, and my opinion is that if someone is smart enough to spoof your MAC address, they're smart enough to get past your encryption. So, I find MAC filtering sufficient.

One of the simplest ways is to set up your wireless router so it does not broadcast it's SSID, that's what I do plus MAC filtering and WEP.
If the hacker can't see it I suspect he can't hack it.

That is the biggest fool thing we have ever done. The Atomic bomb will never go off, and I speak as an expert in explosives.
