Hi,

I've just installed a TL-WN751ND Wireless adapter in my PC. Immediately after installing it connected to my home Wi-Fi without a problem. However, when I then rebooted the PC it would no longer connect - after I enter the Security Key (the same Security Key with which I connected first time round) it tries to connect and then gives the error message 'The key may be incorrect' and asks me to re-enter it - and then the same thing happens.

To rule out the obvious, the problem isn't the security key - apart from having successfully used the same key when I first installed the adapter, I've also got umpteen other devices in the house connected to Wi-Fi with the same key without a problem.

There isn't an issue with wireless signal, for the purposes of getting this working I've moved the PC to right next to the wireless router and it's showing a strong signal on the TP-Link utility.

After trying many times to reboot the PC, connect with the Windows wireless utility instead of the TP-link software (I'm using Windows XP), uninstall and reinstall the software etc, the ONLY other time I've managed to get it working was by uninstalling the utility software and driver, removing the adapter, rebooting without either hardware or software, power down and reinstall both the adapter and software (driver and utility) - and as with the initial installation, upon completion of the software installation it connects perfectly using the same security key that wouldn't work earlier. I then rebooted the PC and was back to the 'The key may be incorrect' error message!

So in summary it only works immediately following installation of the hardware and software. After that as soon as you reboot the PC it thinks there's a problem with the srecurity key. Any ideas greatly appreciated, this is driving me up the wall!

Thanks,

Richard
