Got a bit of a problem that I hope someone could be able to help me with.
I recently reformatted an old Dell E5520 Laptop and installed my own personal copy of Windows 7 Ultimate. However, I can't seem to connect to my home network using the built-in wireless adapter (Intel® Centrino® Advanced-N 6205, Dual Band). When I try to connect, I get a message from the Network Sharing Center panel that says:
Windows was unable to connect to NETWORKNAME
When I check the Event Viewer logs, it says:
Your computer was not assigned an address from the network (by the DHCP Server) for the Network Card with network address xxxxxxxxxxx. The following error occurred: 0x79. Your computer will continue to try and obtain an address on its own from the network address (DHCP) server.
The drivers I have are updated. I downloaded them directly from the Dell Website.
Things that I have tried:
- Connecting via Ethernet. This works. I am able to access the network, and use the internet connection too.
- Moving my laptop closer to the router
- Disabling and re-enabling the wireless adapter
- Disabling the Windows Firewall
- Restarting the router
- Uninstalling/reinstalling the driver
- Running "netsh winsock reset", "netsh int ip reset", "netsh int ipv4 reset reset.log" and netsh int ipv6 reset reset.log" through the command prompt
- Checking if any filtering was present on the router
- Disabling TCP/IPv6 for that respective adapter
- Manually connecting to the network, by typing in the SSID, encryption type and password
- Updated my chipset drivers, just in case.
