Common Network Connectivity Issues and How to Solve Them

If your PC is having problems connecting to a wired network the first things you should check are that your ethernet cable is plugged into both your PC and the router/modem that you are using, and that the router/modem is switched on. If all of the wires are connected properly, green LEDs will flash on both the RJ45 slot on the computer where the ethernet cable is plugged in, and on the port on the modem/router where the other end of the cable is plugged in. If one of these lights isn't flashing you will be able to see whether the problem is the PC or the modem/router. If neither light is flashing, try using a different cable and see if you get a result that way.
If the problem is with your computer, you can also try downloading network drivers from your computer manufacturer's website. If the problem is with the router/modem you may have to call your ISP to have someone come out and look at it.
If updating the computer drivers doesn't solve the problem you may have to consider purchasing a new network card, or having someone fit a new network card.

As always these are just the basics!
