I encompass a Inspiron 1545 through a 1397 Wireless LAN mini-card. At the same time of upgrading to Windows 7 I uninstalled the wireless utility, however at the moment I cannot connect to WPA or else WPA2 networks. I am able to connect to further wireless networks as a result I have assurance that my card still functions. I have established that my drivers are up to date too. It is extremely significant I get this connection functioning. It is the network which I used at job and I have no power to alter it from WPA2. Any suggestions? Thank you in advance.
