Hello, I have a toshiba satellite laptop with a Cisco wireless LAN adapter. At school, I use VPN dialer to access the school's secure wireless network. But at home, even though my computer detects several local wireless networks, I cannot tap into any of them to browse the internet or check e-mail... even when the signal strength is "good" to "very good." A couple of my friends have come over to my place, and their laptops have been able to access the internet through these networks just fine... but for some reason, my laptop can't. Can someone help? I would really appreciate it! Thanks in advance.
