I can't connect with Ethernet cable but I can connect with my wireless. What to do?

[GTB]

It is hard to say from here.

I will assume the CAT5 or CAT6 cable is in good shape (they can develop problems especially if one of the connectors is subjected to physical stress) but this can be faulty.

I have seen times when a network adapter becomes confused and connectivity drops. I usually do this:

1. Open command prompt (click on start, type cmd in the search bar and hit enter; it brings up command prompt. Stretch out command prompt to cover the entire top to bottom distance of your screen (you cannot make it wider). At the > prompt in command prompt, type in ipconfig and hit enter. You will see a lot of information. Look for the Wireless connector and you should find its ip address, subnet mask, and default gateway. Next look for the Ethernet network adapter (not Bluetooth which may also be shown) and see if it has an IP address, subnet mask, and default gateway (subnet mask and default gateway should be the same as seen for the wireless; the first 3 sets of numbers in the ip address should be the same as the default gateway.). I suspect you will see no IP address or if you see one it is not in the same subnet as the wireless address.

2. Open control panel (start, click control panel on the pop up that arises when you click on start). Change the display of control panel to small icons if you are not seeing small icons. Click on Device Manager.
