My wireless network connection works great exept thay it takes about 90 seconds to connect. My girlfriend's V570 connects in about 5 seconds. Any suggestions? Should IPv6 be connected?
If the router configured on IPv6 then the system will support.
Make the wireless card driver update along with router firmware to have good connectivity.
