I am operating on a Toshiba L655D-S5025 laptop. I am running Windows 7 Home Premium 64-bit with a 2.10GHZ AMD Athlon P-320 Processor. I am unable to connect via wi-fi. When I attempt to fix the problem, the statement "An error occured while loading troubleshooter: An unexpected error has occurred. The troubleshooter wizard can't continue." When I select the option "view error details", the following appears: Package ID: Unknown Path: C:\windows\diagnostics\system\networking Error code: 0x8007045A Source: Command line User: AshleighBates\AshleighBates Context: Restricted System Restores have been unsuccessful. I am questioning whether or not the system has been compromised. I do not have the original system disc to complete a full re-install.

Hi, Could you receive the Wireless signal? If not, please ensure the wireless network card drive has been installed successfully and the wireless function has been turned on. If you can connect to wireless but cannot access the Internet, please check DNS configuration.Kim Zhou TechNet Community Support
