Connected to network but no internet access

[ianauyong]

hey guys i'm new here so please help

my desktop is running windows 7 home premium 64 bit and just recently it doesnt have anymore internet access. its connected via cable to LAN. it says that i'm connect to Local Area Network but no internet access.
i thought it was a faulty network card so i bought a wireless USB TP-Link. i set up everything correctly according to the steps (install the driver etc.) and it says i'm connected to my home wifi network. but when i try to access google or facebook or twitter or any other webpage on my internet browser (google chrome), it says the webpage is not available.

please help as i desperately need to use my desktop for work purposes and cant cope with my laptop alone.

thanks

Hello and Welcome to Seven Forums,

Have you tried unplugging the network cable from the router's ethernet port then move it to another one?

Can you post an ipconfig /all output for review?

Also, try running the Network Troubleshooter tool from your Windows 7 computer.
