A friend of mine has an HP Pavillion dv6000 which would not connect at his house. So, I brought it to my house just to find out it will not connect wired or wireless to my router either. Interestingly, the name of of wireless does show up in the list of available wireless networks with full signal strength. However, there is a message indicating it has Limited Connectivity.
When I checked the status of the wireless, there is not any connectivity for both, IPv4 Connectivity and IPv6 Connectivity. I do see the name of my wireless though. With regards to the network connection details, it is as follows: There is not anything for Connection-specific DNS, the name of the wireless adapter and its physical address is displayed, along with DHCP being enabled. Also, for Autoconfiguration IPv4, I have an IP address of 169.254.36.152 and an IPv4 Subnet Mask address of 255.255.0.0. There is not any value for IPv4 Default Gateway, nothing for IPv4 DNS Server, and nothing for IPv4 WINS Server. And, there is a value of Yes for choosing NetBIOS over TCP/IP. There are values given for IPv6 with the exception for IPv6 Gateway, which is nothing.
When I visually inspected Device Manger, I found the network adapters (e.g. Broadcom 802.11g Network Adapter and NVIDIA nForce Networking Controller) show good and free of device driver conflicts. The OS is Windows 7 Ultimate and the version of IE is 8. Speaking of IE8, even when there is a direct wired or ethernet connection to the router, I get the error message Internet Explorer Cannot Display the webpage.
In closing, I know I have probably gone overboard with all of the technical details about this situation, but, if I omitted anything or if there are followup questions about any of the information, please feel free to let me know and I will get back with everyone promptly. In the meantime, I look forward to reviewing and trying out any suggestions or ideas given.
