Question about Belkin Wireless G Plus MIMO (F5D9230-4) Router (1010835)
When you say at the main router are you implying that there is a cable
between routyer and computer? But it works when you plug in the USB
The computer downstairs is this trying to use wireless?
Without this info it is hard to tell what is going on (also the device model numbers). So I'm going to give you a quick IP lesson and hopefully you can troubleshoot this yourself.
Near the end of writing this I found some more specific info for your router. Read entirely before trying my suggestions. This is only one of a possible 3 other problems you might have and encourage you to write back if this one doesn't work. We will fix your problem. I as a electronics tewch believe the more knowledge my clients have the easier it is for to diagnose over the phone (I am disabled) so bare w/me.
The first thing to understand is how computers hook up to the Internet. A computer most hook up mechanically between itself and the router. This is done either plugging cables directly from the computer to router or via a wireless interface. This establishes the mechanical connection only - it has nothing to do with the Internet yet. Once this is done than you establish the software connection. This is when the TCP/IP, WWW. E-mail, etc come into play. These are all software and establish their own set of protocols (how the computers "talk to each other). Each device is given an IP address such as 192.168.0.100. The important part of this is each device on your network must have first 3 octets (192.168.0) assigned to it. The fourth part (.100) is the individual number of the device. There are also 2 other addresses you need to know about. One is called the subnet mask; it is always set at 255.255.255.0. The other is the default gateway. This is the actual router address. Here is a point of confusion for many people. A router has 2 addresses, one on the private side (your side) and one on the public side (ISP's side.) A router also has a piece of software in it called a DHCP Server. This means the router assigns an IP address to your computer. This is called dynamic addressing. The other way a computer gets an IP address is to assign it at the computer. This is called static addressing. Netwok devices come set for all intents and purpose. These setting are called the default settings. Depending on the individual manufacturer, these settings will vary. The default router IP address might be 192.168.0.1, 192.168.1.1, 192.168.2.1, 10.0.0.1, 10.0.1.1. But do notice that it begins with 192.168 or 10.0 . These addresses are saved specifically for the private side of networks. Keep in mind that I'm just simplifying the process for you but this should be all you need for this purpose. Routers always end in .1 (unless there are mutiple).
I suspect your computer has an interface problem with the IP addresses. But let's check the mechanical interface first. At the bottom right of your screen (where you see the time) there should be a network icon (looks like 2 monitors, one behind the other). If it does not have a red "x" through it this means your are connected mechanically. If not, write back and we'll go through fixing that.
First we are going to check the IP addresses. All clicks are left clicks unless otherwise stated. I am also taking it for granted you are using Windows XP with the basic settings. Click the "start" button. Click "run" (usually the lower left in the start menu). Enter "cmd" in the box that comes up at the bottom left. This brings up the command prompt screen (old DOS window). Type "ipconfig" , then press enter key. It should give you three pieces of information: IP address, subnet mask, and default gateway. The IP address and default gateway should look similar except the last digits. The default gateway should be xxx.xxx.xxx.1. The IP address xxx.xxx.xxx.xxx (last group anything but .1). The subnet mask should be 255.255.255.0.
OK - just found information for your specific router. The default IP address is 192.168.2.1. Just for giggles - don't close the "command prompt" window yet. After you have the information from the ipconfig command type "ping 192.168.2.1" exactly as I have it written (space between the g and 1). It should come back with 4 lines of
"reply from 192.168.2.1, etc".
If this you DID get the second reply, then close everything and you should be at your normal XP screen. On the lower right side, find the network icon as described above. RIGHT click the icon. A small window pops up. Click "repair". This should make it work.
If it still doesn't work we need to futher diagnose the problem.
