Answer 1

We need more info.

Reboot the modem and router and all downstream pcs. Leave modem off for 0.5 minutes or more and turn it on; leave router off for 0.5 minutes after you have turned on the router. Turn on notebook 0.5 min or more after the router has turned on. Leave other pcs off for now.

Is your laptop connected via wired or wireless?

If it is wired, did you change cables and are you using a cross when a straight should be used?

If it is wired, first change to a wired connection and see if things work. If they do, we know the router and WAN side work.

With the wired connection do this:

Open command prompt (start, run - type in cmd and hit enter). Type in "ipconfig /all" without quotes and hit enter. You should see an IP address for the wired connection. If the wireless connection is functioning you should see an IP address for it. In addition to the IP address you should see a subnet mask (255.255.255.0 usually) and a default gateway (192.168.x.1 usually where x = 0 or 1 usually). The IP addresses for the ports should be in the format 192.168.x.y where x is same value as is for default gateway and y is any value from 2 - 255; the wireless port should have a different last number (y value) than the wired port. If you have an IP for wired and not wireless you have a wireless config problem either at your wireless network interface on the laptop or on the router. Check both out. Once fixed, the "ipconfig /all" will show an IP address for both ports.

Once you have IP addresses on both ports, then in command prompt type in "ping 4.2.2.2" without quotes and hit enter. You should see 4 positive ping responses - indicating the router WAN config is ok; if you do not see this address router wan config until you do. Now in command prompt type "ping yahoo.com" and hit enter. You should receive 4 ping responses; if not address DNS config in router WAN config. Once this works, you are in business and the wired connection can be disconnected.

Never try to configure or address the router itself via a wireless connection.

If you move the laptop you may block the wireless signal as it cannot go through masonry, metal (like ducts), silver back mirrors on the wall, etc.

You can now turn on other pcs and all should work.

First, make sure your connected from your laptop to your ISP router/modem via cable or wireless. Second, go to your network connections in the control panel (assume windows?) and see if your modem connection is present. Also see if your specific network card is recognized. If your card is recognized the problem is most likely in the modem/router. Contact your ISP.
