WPA2 hack: How secure is your Wi-Fi?
This will test you.
HP XP laptop will not connect to a wifi or rj45 connection, constantly seeking ip address.
router works with all the other pcs no worries and rj45 cable is good.
have run winsock fix, taken out TCP/IP and reinstalled it, checked that it is set to automatically get the ip address.
uninstalled kerio firewall just in case
run malwarebytes which came up with nothing significant, no trojans
have reset internet explorer.
Uninstalled the realtek rj45 driver & reinstalled.
Anyone have any suggestions what to do next

Check that the wireless card is “Enable” from inside the Network Connection Area
