I am running an hp g4 notebook with windows 7 64 bit. I can connect to my home network just fine, but I am unable to connect to any public network. The networks show that the connections are available, but when I try to connect I either get a cannot connect error or connected but with no internet error. I have updated the driver for my wireless adapter (Broadcom 4313GN 802.11b/g/n 1x1 wi-fi) and tried resetting the winsock, dv4 and dv6 in ipconfig. No luck with either. The networks show as open.
