This is my diagnostic.

My PC connects to the router. My PC is set to automatically find IP and DNS.
My PC tells me that it is connected, and, sometimes it says that it has Internet Access, and sometimes not.

My other devices (iPod and Android phone) are connected to the router and DO have access to internet.
In the router settings, in WAN section, it appears my ISP IP.
My PC isn't blocked by MAC filtering.

ping www.google.com request time out
ping 127.0.0.1 responded

I've tried to enter to a website by its IP address without sucess, so I've discarded that it could be a DNS problem.

I've tried with the firewall disabled.

I've reboot my PC a couple of times.

I've uninstall the drivers of my wireless card, and reinstalled it again.

Now it keeps showing me that it IS connected and do has internet access but can't access to any website, only the router webserver.

EDIT: I've rebooted the router from the web server (because u don have phisycal access to it) and Internet worked fine for 5 minutes!

Did you try pinging an ip address? Does that go though?

If you can connect with that, then perhaps there is some spyware hijacking your http requests. Go to internet options in internet explorer, advanced tab, reset and restore advanced settings. I would try installing a 2nd browser. If you can connect to the internet with another application that is not a browser, that could be the case. Try Spybot Search and Destroy to check for and remove any spyware.

Make sure the network adapters IPv4 settings are set to obtain IP address automatically, and there is no other configuration. Also try "ipconfig /all" at the command prompt, and tell us what it says.

Seeing as it works sometimes, maybe its a wireless issue. What type of wifi do you have? Perhaps the phones are connecting on G, and the PC is on N or AC, which is dropping out.

Thanks for replying! However it's not the case.
I've rebooted the router again and it worked fine for ~8 minutes and has just died again! It's strange. Only in my pc. I'm posting with my iPod connected to the same WLAN ...

I was saying that even though they are all connected to the same router, they could be using different WiFi Standards, and there could be a problem with only the PC's connection. Try changing the Wifi from Mixed Mode (A,B,G, or N & AC) to just G.

Is this a USB Wifi Card? Can you tell us the model of the wifi card and router.
