It may seem like a stupid question but why exactly do you need to use WEP encryption? Could you do what you want another way by assigning a unique SSID and other methods of protecting your internet connection with a firewall on your PC and Laptop? Or are you you right in the middle of a building or physical address that prevents you from doing anything other than WEP encryption?
Man it seems like you have been through a lot of trouble to get this to work so far.
If I'm understanding you have no actual hardwired connection to your router from your 8400- is that right? If so have you tried connecting by hardwire from the 8400 to the router and enabling WEP? Just to see if it allows you to do the WEP thing with this PC- even if not wirelessly for the moment?
It also seems clear it is not the 2 USB wireless adapters, since they both work on your laptop with WEP enabled.
So it would seem logical that the problem rests with your router, possibly, or your 8400 machine. Have you searched the web site of the router mfg. for any clues as to what you have found so far. It seems strange that the USB adapters work on the laptop through the same router but not from your 8400.
Do you find any yellow exclamation marks in device manager or is anything disable there- or do you show two of the same thing like adapters, etc.
Let me know re: above questions.
I was asking the person who posed the original question about why he needed to use WEP encryption on HIS specific system. Since neither he nor you can get the wireless cards to work properly with WEP it is better than nothing to change one's SSID instead of leaving it set on the default. Some protection in this circumstance is better than none and his neighborhood may not be a drive by hacker's paradise as it seems some people's neighborhood's are.
Forget getting Dell to do anything about bogus functionality on wireless cards. Until enough people scream at them or word gets out about the cra* card they will not resolve it. This happened with Conexant modems with Win ME a few years back.
So if you want true results dispute the purchase on your credit card bill within 30 days of purchase. Otherwise you're basically spitting into the wind.
No problem - I was also trying to find some solution for the person who was so frantic about WEP.
Ask Dell for hardcopy verification of what they are going to send you. Sometimes promises are made and forgotten. Get an e-mail confirmation and description with part number so you can determine what they are sending you.
From many years of experience with Dell and other companies - paperwork is the only way to get anything done to finality.
Good luck, :smileyvery-happy:
