Two weeks ago my family acquired a Dell Inspiron 1525 laptop running on Vista Home Premium. A couple of days ago, I used it to browse the net wirelessly at my brother-in-law's home. It was able to connect to his wireless network perfectly via a Netgear router.
Today we bought a Linksys WRT310N router. I installed the router on our desktop. It is now plugged in our old broadband modem. Both gadgets work compatibly. Our desktop can do its usual PC chores including internet-related functions
Our Dell Inspiron 1525 connects to a wireless network or with an ethernet cable via our newly installed router. However, the laptop cannot view the internet. I use Mozilla Firefox and Internet Explorer as our browsers. All I get from them is "Address not found" or "Internet Explorer cannot display the webpage," respectively.
A Linksys technician has already helped me (over the phone) go through a long and tedious process of configuring and re-configuring the router... to no avail. She said the problem must be already in what's contained in the laptop.
Could it be the OS or the laptop itself? What should I do? Need help.
Once your laptop is connected to network, type following command in command prompt(cmd.exe) to make sure it displays correct IP, subnet mask, gateway and DNS info. You should be able to ping the gateway IP too if it's connected properly. If not, your laptop is not connected correctly.
