Windows was unable to find a certificate to log you on to the network

[LukeWard7]

I've searched on Google but I didn't really understand. I can log on fine to the network, but when my girlfriend brings her laptop round and she tries to connect it comes up with this error. Also, it doesn't even give her the chance to put in my WEP key. Whats the problem?

First off, WEP? Really? You should atleast be using WPA by now, if not WPA2!

Sounds like shes set her wireless to use 802.11x? (i think thats what its called).

I little more information would be helpful.

Yeah sounds like a client misconfiguration to me -- WPA-enterprise vs PSK, etc.

Maybe you just got the term wrong, ie your using WPA -- WEP is no longer a valid method of securing your wireless, unless you using hardware that does not support at min WPA.. Hint -- get new hardware if that is your case, WEP is no longer really viable as a security method.

Uhuh, these guys are correct.Are you actually using WEP? If so is your router set-up as WEP-EAP? If that is the case change your routers security settings to WEP-PSK.

When you change to WEP-PSK you will need to create a pre-shared key and enter this on all of the devices you want to access the wireless router.

However, as the guys have mentioned above, try not to use WEP if possible. It is easily cracked by your average Joe. WPA with TKIP isn't much better. If the option is available to you select WPA2-Personal with AES and not TKIP.

What wireless router are you using? Perhaps we could help walk you through the configuration!

WPA with TKIP isn't much better.

I don't agree with that at all -- WPA is way better than WEP, unless you were using some ****ty ass passphrase like Password or some other dictionary word, etc.

But WPA with say a random 20 character passphrase is secure. Sure there has been some talk of lately of the new WPA TKIP attack -- but from everything I have been able to read -- its more bark than bite. It is not a way to get the PSK, etc. That still has to be bruteforced - but it does allow for a method to send packets to a wireless client, etc. So sure it could be used maliciously ;)

But sure you should always be using WPA2 if your hardware supports it ;)

Absolutely, there is only the potential to decrypt messages from the AP to the Client. This however opens the door and if AES is available in the hardware, mandatory since 2006 for wi-fi alliance certified hardware, then I would recommend its use to everyone :)

Well you should read this paper on the attack

http://dl.aircrack-ng.org/breakingwepandwpa.pdf

Like I said it seems to be a lot of bark mostly -- but I agree that AES should be used whenever possible. Why anyone would not the most secure method secure their wireless that their hardware is capable is beyond me.

I think we agree on that, its just making a statement that WPA tkip is not much better than WEP is nonsense ;)
