Interesting how the question asked was trying to get old wifi cards to connect to a router, and the conversation has morphed into why WEP sux, and why you shouldn't do it, and get something better. Not that I have a good answer, but here's a novel concept, lets at least attempt to answer the question or help troubleshot the issue. <br>
<br>Personally, I might turn off all encryption for a while, and see if that solves the problem. That would tell me if that card has the ability to connect to that router at all. I have resorted turning off encryption completely, and putting a white list of MAC addresses of computers that are allowed to connect. Yes, people could spoof a MAC addr, but I know my neighbors, and they're not that smart.<br>

Josh++<div><br></div><div>He's right - WEP is stupid simple to crack now days... open a program, pick a wifinet, and wait. Scary sometimes how fast it can be done, too; a few hours... sometimes less. Regardless, if you're not worried about it, and they aren't worried about, then okay; you have the right to know I think is all Josh is getting at. (and judging by his sig, I think his advice is qualified) :)</div>

A decent card might set them back $50-$100, but that's minuscule in comparison to what could be spent on a lawyer and/or fines if someone were to gain access to and use the service for dirty deeds. <DONE DIRT CHEAP /></div>

That means that they can read all non-encrypted traffic (i.e., HTTP is readable, HTTPS is not). They can also authenticate to the WAP (by providing the key) and be on your network. From there it depends on network design.<br>
<br>
If you're using MAC filtering, they can usually bypass it. If you're using DHCP, they can usually statically assign something in that range and have it work. None of this, of course, matters much if your wireless traffic goes to a DMZ and then out to the Internet*... especially if you're doing egress filtering. However, if you're like most people and just slap a WAP on your internal network and trust WEP with a key of "Password123" to keep your stuff secure, you have a problem.<br>
<br>
Not as big a problem as running a node of the Global Linksys Mesh Network, but a problem nonetheless.<br>

Question: What exactly is cracked? Is it just that a person will be<br>
able to read traffic to and from the router? Or could they also<br>
connect to the router and get Internet access by cracking WEP?<br>
