HELP :cry

 

No, I am not on my sons computer, I'm on mine. it is about his computer. the latest news is that he took it to a computer service and it worked just fine and connected to the net. yet mediacom claims it is his computer that is the problem.

 

sorry, all my info is second hand over the phone. I think he has hard wired and wireless both. anyway he says when he tries to connect his pc says he is connected to the other, ie hardwired or router. always opposite of of the way he is trying to connect. he is looking for a laptop he can try. also mediacom installed a new modem and same problem

 

additional info: op is windows vista and he checked the internet properties and connections and everything is as it should be. he is also looking for a laptop he can try on his connection

 

this bit of info from the web has helped me on numerous occasions Repair and Reset Windows Vista TCP/IP Winsock Catalog Corruption To repair and reset the Windows Vista 1. Click on Start button. 2. Type Cmd in the Start Search text box. 3. Press Ctrl-Shift-Enter keyboard shortcut to run Command Prompt as Administrator. Allow elevation request. 4. Type netsh winsock reset in the Command Prompt shell, and then press the Enter key. 5. Restart the computer. What netsh winsock reset command does are it resets Winsock Catalog to a clean state or default configuration. It removes all Winsock LSP (Layered Service Providers) previously installed, including the potential malfunctioned LSP that causes loss of network packets transmission failure. So all previously-installed LSPs must be reinstalled. This command does not affect Winsock Name Space Provider entries. Note: To check which LSPs installed on your Vista system, use netsh winsock show catalog command. --------------------------------------------------------------------------------------------------------------------------------- Reinstall and Reset TCP/IP (Internet Protocol) in Windows Vista For Windows Vista, things work a little different due to introduction of UAC (Guide: Disable UAC). Use this guide to perform a reinstalling of TCP/IP protocol in Vista: 1. Click on Start button. 2. Type Cmd in the Start Search text box. 3. Press Ctrl-Shift-Enter keyboard shortcut to run Command Prompt as Administrator. Allow elevation request. 4. Type netsh int ip reset in the Command Prompt shell, and then press the Enter key. 5. Restart the computer. The command will remove all user configured settings on TCP/IP stack and return it to original default state by rewriting pertinent registry keys that are used by the Internet Protocol (TCP/IP) stack to achieve the same result as the removal and the reinstallation of the protocol. The registry keys affected are: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\ and HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DHCP\Parameters\ --------------------------------------------------------------------------------------------------------------------------------- Clear, Delete and Refresh ARP Cache Entry Windows ARP cache will occasionally become corrupt and need to be cleared and deleted so that the cache can be refreshed. When you haven’t problem connecting to Internet where connections to websites or web pages will time out or fail, and unable to surf or browse the Internet pages, the error may because also of ARP cache corruption, other than TCP/IP corruption or Winsock error. To confirm that it’s indeed an ARP issue, try to ping both the loopback address (127.0.0.1) and the local computer’s IP address. Then try to any other IP addresses such as those of Google.com or Yahoo.com. If you can ping to local IP address and loopback address, but not any other IP addresses, then this is the typical symptom of ARP cache failure. Use the NetShell (netsh) command to clear, delete or refresh the Address Resolution Protocol (ARP) cache by following the following steps. 1. Click on Start button. 2. Click on Run command and type Cmd into the Run text box, and then press Enter. For Windows Vista, type Cmd in Start Search, and then press Ctrl-Shift-Enter keyboard shortcut to force Administrator privileges. Enter Administrator user ID and password and allow any permission request when prompted. 3. In the Command Prompt window, type the following command then press Enter. netsh interface ip delete arpcache The command works in Windows Vista, Windows XP and Windows 2003.
