New Windows 7 install can't get past router
Posted on 2011-09-19
I have just reinstalled Windows 7 Home Premium on a Toshiba Satellite C655D-S5130. After installing the driver for the wired network device (Atheros AR8152/8158 PCI-E Fast Ethernet Controller NDSI 6.20) the laptop can obtain an IP from the cable router. However, the laptop won't connect beyond the router. The network troubleshooter constantly asks for the router to be rebooted and I have done that twice. However, I am typing this on a different laptop running Windows 7 Home Premium running through the same router so I don't see how the router could be the problem. I also installed a USB wired network dongle and tried using it but I get the same results (ASIX AX8772 USB2.0 to Fast Ethernet Adapter-Trendnet TU2-ET100).
Ipconfig /all on the laptop shows a proper IP address and netmask assigned and that the default gateway is recognized. It shows that DHCP is enabled and autoconfiguration is enabled. It also shows NetBIOS over TCPIP is enabled. The Device Manager says the network adapter is working properly.
The laptop is using Windows firewall but I have turned that off and tried it and still get the same results. There is no anti-virus software installed, yet.
The message I keep getting from Windows is, "Your broadband modem is experiencing connectivity issues." Then it asks me to restart the modem.
Can anyone shed any light on this situation?
