I have been beating my head up against a wall for the past month on this one. I have these two laptops, same model doing the exact same thing and I can't figure it out.

I have two HP ProBook 4430's. They both get a strong signal on our wireless AP's at work, we enter the WEP key (which I know is correct) "Windows was unable to connect to "wireless AP Name". I've tried a number of things resetting the AP, loging onto the access point (when I did I was sure which settings did what so I left them alone.)  tried letting windows repair the problem, which does nothing. I've had other laptops right next to me log on and work just fine. I tried Re-Installing windows 7, nothing same issue. I also searched for driver update for the wireless and there are none. But when I take this home I can get onto my wireless network at home just fine. I'm losing my mind I have never experienced something like this before. IM LOSING MY MIND!!! Here is the ipconfig /all:

when I take this home I can get onto my wireless network at home just fine.
So far, so good.  Is the wireless at home secured?  If so, with what method?  Probably not important but information ...  Suggests that the radios are turned on.

They both get a strong signal on our wireless AP's at work
Also suggests the radios are turned on.  

I've had other laptops right next to me log on and work just fine.
Had they been assigned an IP address before that?

Are the wireless interfaces set up for static IP or automatic (via DHCP)?
If static and outside the DHCP range and not duplicated, then it should work.  Of course, the static at work and the static at home are likely different.
If dynamic / auto / DHCP then is there any possibility that the DHCP pool at work is full?  How many addresses are available?  How many are leased out?  How long are the leases set for.? I would suggest 8 hours.

Do the laptops worked *wired* at work?  Looking for firewall issues here.

I've tried a number of things resetting the AP, logging onto the access point (when I did I was sure which settings did what so I left them alone.)
Do you mean that you turned off the AP security here or not?
That would be a good test ... with it OFF / disabled.

Presumably this means there are no MAC filters set up on the AP.

Do the laptops provide you with a software selection for wireless connections?
If so, I'd try the "other one".  That is there will be Windows software and often the wireless chip manufacturer's software.  Try each and see which works best for you.
I'm not too high on the Dell softare (which is a 3rd choice) but that's not your situation.  Yet, there may be an HP 3rd choice....

Fmarshall, thanks for the reponse.

-My wireless at home is secure after I enter my password I get on no problem. The radio's are on

-When I was logged onto the AP earlier I was checking to see if it was static or DHCP here is what I saw. In the "Configuration" tab I click on "IP Setting" It says "DHCP Client" is Disabled.
Under "IP Settings" is "DHCP Server Setting" that is also Disabled. Does this mean that everyone that connects to these access point have a Static IP? It shows that the lease is for 1 day.

-In the "Wireless" tab under "Advanced Settings" Client Isolation is Disabled and it says that "Max Wireless Clients" is set to 64. It also says Rogue AP Detection is Enabled

Not sure what to edit, if there is something to edit. Don't want to screw up the wireless for the people its working for. Which is mainly everyone but these two.

Thanks

Well, if it's indeed an Access Point then having the DHCP turned off might not be too unusual as there could be a DHCP server elsewhere on the network.  Is there?  Then the same questions apply.

What did you use to log into the AP with?  How did you reset it without resetting it???

How many wireless clients are there?  64 max yes but how many now?

You'll laugh but I work at a small catholic school. We don't even have a firewall. I would say at most there is 10-20 users on one AP at a time.

 I don't think there is another DHCP Server, As a matter a fact I'll tell you what we have. A server running MS Server either 2000 or 03. Its really old, 2 computer labs with 60 workstations hard wired and about 120 laptops running off the wireless. We have 2 small buildings with 3 wireless AP's at each building. 1 AP for each floor. 6 Ap's total.

Well, I entered the Ip Adress of the AP into my browser and logged in with the Admin iser and pass. And I reset it by Power Cycling it and then when logged into the AP I reset it there to.
