WPA, or Wi-Fi Protected Access, is the successor to WEP. It’s also possible to spoof the system, for example by pretending to be a preexisting client. Once this conversation has taken place, WEP becomes responsible for maintaining encryption during the extent of the session.Ī weakness of WEP is that bad applications can examine the packets being communicated between the access point and the client and eventually figure out the security key. If all’s well, the router sends, “OK, then talk.” If there’s a problem, the router says, “I know thee not.” The access point looks at the returned message and compares it to the bully good information it originally sent out. The laptop receives this data, munches on it, considers the security key it already knows, and sends back a combination of the bully good information and the security key in a second request for acknowledgment. The router responds, “Do you really want to talk to me?” and transmits some bully good information in response. The laptop says, “I want to talk to you.” For our purposes, the SSID is being broadcast, and the laptop knows the security key. What does a WEP conversation look like? Let’s go back to our imaginary network. A 128-bit key in a WEP network is certainly better than a 40-bit key, but there are other problems that make WEP less desirable than other solutions. This can usually be recognized because the key will contain 26 characters with a mix of letters and numbers (which are called hexadecimal or base 16 units).

At least in theory, all schemes are crack-able, but when the computer time required to crack the key requires years or decades, we can feel pretty secure.

Security, in a sense, is based on time – how long it will take a computer to “crack” the key. Even though that is a large number, small computers can defeat a 40-bit key by using a “brute force” attack that consists of running through all of the possible combinations until a match is made. 40 bits is five bytes, and there are 240 (a really large number) possible key combinations. WEP was originally designed to use a 40-bit security key. So if the laptop is going to blab, what’s the use of hiding the network? The router no longer brags about itself, but what does the laptop do? If the user has it set for automatic connections, it says, “Yoo-hoo, Thunder Dome, are you here? Yoo-hoo, Thunder Dome, where are you?” Imagine a wireless network named “Thunder Dome.” Normally, the server sends out a message at a fixed interval saying, “I am Thunder Dome.” Other devices can see the network and recognize it by name.

Windows lets the user enter the details for hidden networks, and then, enticingly, offers to watch for the network and connect automatically when in range.

This is actually a bad idea, not only because it’s sort of useless – scanner applications can find networks even with SSID turned off – but also because of the way Microsoft Windows Vista (and Windows 7 beta) handle hidden networks. In an effort to “hide” their less than ideal network, these same users may be tempted to hide the broadcast name, or SSID, of the network. Some users also run systems using WEP fully knowing about the weaknesses because they have older devices such as handhelds and laptops that can’t use more advanced security. Some router setup interfaces exacerbate the problem by offering WEP security before offering better security.

If your's doesn't allow that, then you can assign IP addresses manually at each device and set the DHCP assignment range to 1.WEP stands for “Wired Equivalent Privacy.” Although WEP is very common and may be the only method that older devices recognize, it is no longer recommended because it has weak security and can be easily “cracked” with free tools downloaded from the Internet. Just like static addresss but controlled from the router instead of each system independently.

This works for both WiFi and wired connections - say like a guest staying with you for a few days.įor my router, MAC filtering also allows me to predetermine the IP address to be assigned. This moves the problem (of control) to one of managing IP address assignments. then config the firewall(s) to allow Print/File sharing on the former and denied to the latter.get everything else at some other range (x.y.1.100->200).get all known systems into a small range of ip-addresses.Here's my method of controlling the problem. They would get Internet access thru your router+modem.Īccessing your other systems is a firewall issue (on each system). The 'break-in' would occur on the WiFi-SSID side which is actually on the LAN side. Very good - You're seeing the issues well
