Hello, sorry if this the the wrong section, as I didn't see any others that would fit the description.

But the jack for the local area connection in my computer does not work, usually when you plug in a cable it lights up, it doesn't. I've tried different cables, and system restored but none of that seems to be working. Any trouble shootings to do?

As pointed out, driver checking is a good start. A short, ordered diagnostic routine makes it easy to tell whether the fault is software/configuration or a dead network interface, and what to do next.

A reliable first step is booting a Linux live USB (Ubuntu, Knoppix, etc.) to see whether the adapter and its link/activity LEDs behave outside Windows. Useful commands from the live environment:

lspci -nn | grep -i ethernet
dmesg | grep -i -E 'eth|link|ethernet'
sudo lshw -C network

If the adapter appears and the LEDs light, the hardware is likely fine and the problem is a Windows driver, power-management, or driver/chipset mismatch.

When the hardware is detected by another OS, the next focus is obtaining the exact hardware ID and installing the proper driver from the NIC or motherboard vendor. In Windows Device Manager (Details → Hardware Ids) the vendor/device IDs can be used to find the right driver. Also check adapter properties for power-management options (disable "allow the computer to turn off this device to save power") and for the link speed/duplex setting (set to Auto Negotiation if unsure). If reinstalling drivers fails, a temporary USB-to-Ethernet adapter or inexpensive PCIe NIC will confirm whether replacing the adapter resolves the symptom.

If the adapter is invisible in the live OS and LEDs remain off, the problem is probably physical. Verify the LAN controller is enabled in BIOS, inspect the board for damaged components, and test the same cable and modem/switch port with another machine to rule out the external port. Electrostatic caution is recommended when opening the case. When replacement is required, an add-in NIC or USB adapter is a quick fix; warranty service is preferable for integrated-board failures.

Relevant diagnostic outputs to collect when seeking further help: hardware IDs, Device Manager error codes, and kernel/dmesg lines showing the adapter.

Maybe their's a prob with the network card. Which OS are you using?

Have you tried going into device manager and seeing what is there for the network card? It is usually under network adaptors, there maybe an exclaimation mark next to it.

If there is a problem with the network device then you may have to buy a new one.

- Let us know the situation.

Nothing right next to it, when I connected the computer to the 2wire modem, it wouldn't install the drivers because it couldn't find the right software...

Try finding the correct and install that.

If this doesn't work you may need a new one.
