Cannot use internet but connection is good

If it works just fine when you provide an IP address but doesn't when you don't, then it sounds like you have a problem with DHCP.

Go to the command line and type ipconfig /all. Post the results here both with an IP address provided and without. I need to see what it's doing.

Probably DHCP server turned off on the router, go to http://192.168.1.1 and check it out

Here it is:

When I use this configuration to connect wireless, DHCP appears NO enable.

It was off and I changed, but still does not work.

Is your wireless access point built into your router or is it a separate device? If it is a separate device, plug it in to one of the available LAN ports in your router. If it is, change it to a different port. It is possible to assign a LAN port to an Internet address. If this has been done in your router, you probably want to change this.

In section 1, you are showing the MS assigned IP address meaning that an address could not be obtained from a DHCP server.

In section 2, you assigned an Internet IP address and not one from your router. Why is that? Did you connect your computer directly to the modem? If this is connected to your router, then you should assign an IP address similar to the one in section 3 except outside of the DHCP range. Typically, the DHCP range is 192.168.1.100 to 192.168.1.150 in a default router setup. So using something like 192.168.1.80 would be fine. You must use the same subnet mask and gateway address as the DHCP assigned addresses.

In section 3, you obtained a proper DHCP address from your router.

Well, I'm actually correcting what I said, try the following as your IP configuration:

IP Address: 192.168.0.90
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.0.1

DNS Primary: 192.168.0.1
DNS Secondary: 82.216.111.124

The reason you couldn't connect to the Internet when you provided the IP address previously is that your router is configured to work off a private network, with your public IP address only being used on the interface leading to your modem. If you try to assign that directly to your laptop, it's not going to connect properly. Give that a try, also, if you later want to use DHCP, you might try searching the Internet for a file named dhcpd.dll and replacing the copy of it currently on your computer.

Wow, you lost me....well there is only one device: router wireless NETGEAR connected to the cable service. I can use internet connecting the LAN (computer-router). Remember that other computer was able to connect wireless, so the router is working.

Now, when I change the setting as TWILCOX said, nothing changes, in fact the little computer icon on the bottom right of the computer (quick launch) that represents wireless does not blink, bu maybe that's normal cause the one representing LAN does not blink eighter.

%&^(!#%)(& ! What should I do?

What is the model of the NetGear device? I would like to look it up to see what it is capable of.

Mmm... Maybe...would be CBVG834G ? Says NETGEAR Cable Voice Gateway.
