Re: Network cable unplugged

Since it only happens when it rains, it sounds like you may have damaged cable between the modem and the drop. You will need to physically inspect whatever cables you have access to, and you may need to call a field tech out to repair the damaged cable.

Look closely at both ends of the network-cable connecting the network-port on your computer to one of the LAN ports on the router. The eight wires should have IDENTICAL colours & arrangement.

Also, be sure that you connect to one of the LAN ports on the router, not to the WAN port.

Can you try reset the network card and also reset the modem by pressing into the little hole on it for like 30 seconds? To reset the network adapter card, you can right click on the network connection of your LAN connection and click on diagnose if you are using Windows Vista. Then you will see the reset network adapter card option. Or you can follow the steps on the following link.

If you are using Windows 7, then the following link will include the steps about troubleshooting your network adapter card.

troubleshooting a network is a multiple step process.
1. Establish that your modem is working properly, and plugged in. As per the diagram shown here:
  • Your "Cable link" light should be on (signifying that the outside cable is properly connected to the router)
  • Your "Internet" light should be on (signifying you have an established Internet connection)
  • And, most importantly, your "PC Link" light should be on (showing that at least as far as the modem is concerned, it is detecting that the computer is plugged in to it.
2. double check to make sure that the network cables are seated properly, and plugged in all the way. the PC link light should give you an indication for modem-side- the LED light around the network cable jack on the laptop should give you an indication PC-side.
3. check on your laptop for any security software that may restrict new networks from being detected and disable them to test. For example, Symantec or Mcaffee Firewall can sometimes block a "new" network from being detected.
4. Completely shut down the laptop and unplug the power cord from the modem. Plug the modem back in. Wait around 3 minutes for the modem to initialize and do it's thing- then turn on your laptop and see if this resolved your issue.
If this doesn't work, you may want to try other things, such as resetting your network, and removing/re-installing your network adapter drivers.

No internet connection by using the ethernet cable

Unplug the power to the modem and the USB cable. Plug in Ethernet cable in computer and plug in the modem. Wait for WAN side of the modem to connect and stabilize. If your PC is already on, you should see the network connection appear in the task bar (if it's configured to show up). Open a command prompt. Type 'ping' and press Enter. You should get 4 ping responses from the modem which indicates that you LAN connection to the modem is functional.

Let me know if this doesn't work and I'll guide you through other methods to get it working.

Switched to cable(arris modem) can't set up network

cable dsl same thing. Did you switch providers and get new modem from them? If so. Just delete previous netowrk and install new one let pc discover new one. Also, with your router you got a disc. It should install correctly. Perhaps it is previous network that is hindering you.
