I have two separate but related issues.
1. We bought 25 HP 2540p laptops back in January that have HP un2430 mobile broadband adapter builtin. 21 of the 25 worked with no issue. Three of the four that didn't work, still don't work. We have been going around and around with our local HP support, the company we bought them from (CDW), and HP. The motherboards have been replaced, new SIM's have been installed, and still the same issue. One of them has a "No SIM detected" error and the other has a "No wireless device detected" error. We have Windows XP installed on the machines (that's what we have on the 21 that do work as well). I'm not really sure what the problem is, it seems like an HP hardware issue. But then other times seems like a SIM issue. Any thoughts?
2. We bought 3 new machines to replace the 3 that have been not working since January. They are HP 2560p's with the same broadband builtin. Two of them have the "No wireless device detected" error. The third, I left with the factory Windows 7 Professional image and tried connecting to the mobile broadband. When I turned on the mobile broadband in HP Connection Manager it says "SIM rejected by network". So none of the new ones work with the broadband.
We are at a loss as to what to do to try and get these machines functioning. All mobile broadband adapters show up as functioning and the drivers are up to date in Device Manager. We tried swapping the cards from known working units into these with the same error. Any help would be much appreciated.

I have HP nu2430 adapter. I had it installed in a Probook 6460b. Although it did not have the antennas built in the notebook it worked and got very weak signal.
I installed the same adapter inside an Elitebook 8460p and immidiately got "SIM Rejected by network" message. It never worked. I got a second Elitebook 8460p and put the same adapter in there, and this time it worked for about 3 hours before it started displaying "SIM rejected by network" again. Rebooting does not work, however it seems that sometimes it does connect to 3G network for a little bit before giving that issue again.
I have pulled a SIM out of my phone that does have a working data plan and it does the same thing. I doubt that the issue is the carrier.
Rogers Wireless simply does not help and blames the device. They say there is nothing they can or will do for the SIM. I have tried upgrading the drivers to the lates that was released Aug 2012 and again, same issue persists.
This has got to do with network connection settings on the adapter, but I don't see much settings that can be changed on HP Wireless Manager. I would appreciate any suggestions.

I found the problem. The issue is the antenna cables. It seems that in the Probook 6460b and the Elitebook 8460p when the cover is closed it puts pressure on the antenna connection that is right under the cover. If the wires are routed from the bottom this won't happen since there is a slight bump on the cover at that location that touches the wire, but since the wires are a little rigid the cause the connector to get disconnected from the card, hense causing communication errors with the provider. The solution i found to work best is to just use a drop of glue gun and stick the antenna connector (Number 6) to the board so it won't come off.
This problem can be easily replicated by simply moving the antenna #6 slightly so it does not make proper connection. IT can be also resolved the same by disabling the WWAN card in Connection manager and connecting #6 connector properly and enabling the card again so it will scan for networks again.
Hope this could help others who might be facing the same issue.
