Hard to say as it could be a software or hardware problem. I'd try replacing the cable first, if you've got a spare one. Or use a different port on the router if it's got more than one. If that doesn't fix it, try reinstalling the windows driver for the ethernet port. If that doesn't work either then it may be a problem with the motherboard.

Your best bet is probably to get someone who knows what they're doing to test it all for you.

I'll swap the cable first, then try the driver, I prefer diy approach, these experts hit you where it hurts

If other devices can connect through and out fine, then its either your desktop, the wire, or config on the desktop/router preventing it.
Assuming you're on Windows, launch a command prompt from the start menu
In the command prompt, some things to try...
Type

ping www.google.co.uk

and press return
Ideally it should respond with 4 replies from google's IP address. If you've got no internet connectivity, it will probably say could not find host

type ipconfig and press return
You'll get all sorts of stuff back, but see if there's an IP address allocated to you, and what the default gateway is.

See if you can ping the default gateway IP address OK. If you get a reply, you've got connectivtiy OK to the router at least.

Let us know the results....

I typed ipconfig and a screen flashes up for a tenth of a second then goes again , tried it three times and same thing ?
what he didn't tell you specifically, is that you have to open the cmd console first

start

type into search:

cmd

hit Enter

and then type

ipconfig

hit Enter

or

ping google.com

hit Enter


this is it:

Had this the other day, couldn't get to the bottom of it and in the end just went to a weeks earlier restore point, problem solved.

possibly
Uninstall McAfee; we have spent many days trying various solutions to an almost identical problem. No internet via wifi, cable or even using a 3G dongle. On each occasion it found the network and would exchange files across the network but no internet. In the end I uninstalled McAfee and it was fixed! Using Windows Security Essentials for now, been trying to speak to McAfee to see if a recent update has caused the problem.
Step 1. ^ get rid of Mcafee. Its bloated parpware that interfers and uses up resources. (get avast/avg free instead)

Step 2. Check your connections. If other devices connect fine via wifi, then your ethernet cable is probably stuck in the wan port or something. Does it say crossover or patch on the cable itself??

Step 3. If all else fails, save your config settings for your router. Note your ISP details, DNS etc or else if its cable/fiber optic dont worry. Do this by going into your router page (192.168.x.x) in a browser. then reset the router back to factory settings by sticking paperclip into little hole on back, until the lights flash. Go back into setup page enter details or clone mac (for cable/fiber optic). Check that the router has internet access. Link cable into port 1. Right click on Pc connection > disable then enable. See if it works. If so ad password to router and link other wifi devices.
