I have been trying to debug a intel wifi 5100 agn adaptor for the past many months. Currently the issue is the following: I have a WEP wifi setup that has worked without issue on this device and other wifi devices. My HP 6350b w/ intel wifi 5100 agn adaptor whilst running fine on the network will just drop the connection hard with a failure appearing in the HP Wireless assistant as wireless / bluetooth DISABLED. The connection drops and when trying to troubleshoot using standard methods nothing will re-enable the wifi capabilities. Some of the fixes I have followed on numerous posts include the following:
Disabling and Re-enabling the device. Testing that the router is functioning properly on other wireless devices, downloading the latest driver from Intel which is 188.8.131.52, May 2009. This fixed the problem for one day and the next day it failed again. Whilst online browsing the Sydney news the adaptor became disabled and the network disappeared from the Network Center when I tried to connect -- the diagnoses tells me to ENABLE the wireless adaptor. The adaptor tests as active and working properly. I have played with settings, testing the router, even set up a new Wireless with MAC and WPA settings to no avail. I then rebuilit the WEP that had been working and that works for other wireless devices such as a Dell Laptop and Mac Laptop and my iPhone. None of those has the 5100 adaptor. I am at a loss what shoudl I do next? Most forums recommend that this is a hopeless adaptor and that my only option is to replace the card with a different model. Please advise. many thanks!
The first issue was that I had intermittent connectivity when moving from room to room with the HP 6350b notebook. That was when I first purchased the computer and when traveling and trying to find wifi networks in cafe's and hotels the adaptor would not recognise any wireless networks present whilst my iPhone could pick them up immiediately and connect without issues.
My latest issue is one that I cannot tolerate as I am a dedicated wifi worker and cannot really survive on an adaptor that presents all the challenges that this 5100 appears to be experiencing. I have tried the following fixes recommended by HP and by Intel and then alternatively by outside forums other than these official forums as I am at a loss for what to do to fix the issue.
