I'm looking at a friend's Compaq Presario CQ60 laptop which has Windows Vista Home Premium (32-bit) installed. They are experiencing some strange wireless networking issues which I've confirmed. Here's the deal: when they attempt to connect to their wireless network, which is provided through an AT&T U-Verse modem/router, their system gets a valid IP address assignment, along with a valid default gateway assignment, both assigned via DHCP, but they can't access the Internet.
I have the machine in my possession and I've been doing some research and testing and have found the following, so far:
When I connect the system to my wireless network, provided through a Linksys WRT120N wireless router, everything works fine. The system gets valid IP address and default gateway assignments and I can access the Internet just fine.
When I connect the system to my mom's wireless network, provided through a Trendnet wireless N150 DSL modem/router combo, the laptop behaves as it does at my friend's house; it gets valid IP address and default gateway assignments but can't access the Internet.
So, when I connect the system to my mom's wireless network, ipconfig /all shows this:
When I try to ping the default gateway, I get this:
Ok, if I boot Linux on the laptop and connect to my mom's wireless network, I get this connection info:
Here is routing information:
When I ping the default gateway, I get replies back:
Cool. Now, if I connect the system to my home wireless network, ipconfig /all shows this:
When I ping the default gateway, I get replies back.
I've tried updating the wireless adapter drivers using Windows update and the latest drivers are installed. I've deleted the wireless network from the list of preferred networks and reconnected to the network, manually entering the passphrase. WPA/WPA2 TKIP or AES encryption is enabled in both my mom's wireless router and in my wireless router. I've tried changing the encryption in Windows from WPA2-AES to WPA-TKIP with no luck. I haven't touched the encryption setup in any routers.
What boggles my mind is why the system works with my mom's wireless network while running Linux but doesn't when running Windows Vista. While running Windows Vista, if I connect an Ethernet cable from the laptop to my mom's router and turn off the wireless adapter, I can get online just fine. It's only the wireless connection that is having problems and the problem is the system can't reach the default gateway, for some reason. I've tried disabling the Windows firewall and that doesn't help either.
Any ideas or suggestions of things to try or change?
Thanks!
