WEP question

Do you have a question? Post it now! No Registration Necessary.  Now with pictures!

Threaded View
Just bought a wireless  Dlink router. A few questions...if you can point me
to a Wireless for Dummies type webpage that would explain all this I would
be grateful. Anyway, here goes:

The setup program asks me to enter an encryption key. Now, once I enter the
key, do I have to remember and write it down so that if I want to later add
a laptop to the network I, I enter this string for the wireless card?

 ...Or does the laptop I'm setting this up from save the key somewhere so
that they can continue to talk once I enter the key.

Is the key just another kind of password..for example, is the string I enter
the actual key, or is the key generated from the string.

How does the key move from the router to adapter on the computer I'm setting
up the router from?

Does all this key business have any effect on wired connections to the

Also if the laptop moves to another wireless network does it somehow
remember this string that I entered belongs to the original network and
reconnect when it comes back home?

How much slower is 128 bit encryption than 64 bit (if any). (this is a
802.11g 2.4 Ghz system)?

Why do fools fall in love?

Re: WEP question

I guess you are talking about the WEP protocol, not the new 802.11i. You can
find several papers describing WEP's flaws on the Internet. For example,

Yes. Or maybe you can read it from the wireless software on your first

It is the actual key (or actually a part of it, it is concatenated to an
initialization vector to form a per packet key). This is from which most of the
flaws originate.

When you connect to the wireless network, the access point authenticates the
network card. This requires that the same key is intalled to both the devices.
After the authentication the traffic is enrypted with the same key.

There are usually profiles for different networks in the wireless software. The
keys are stored in the profiles. When you switch to another network, the
corresponding profile is applied.

The same speed.

since you have 802.11g, you can probably update your firmware and use WPA
(with shared key) instead of any WEP, which is much safer for all the
wardrivers out there... but be sure you download the correct update from
DLink, 'cuz they tend to name the products all alike...
so maybe it's better if you find someone to do it for your.

WEP is secure, but not if someone WANTS to get on your network, it takes
only a few days maximum to get in... and since all the necessary tools are
free to download...
