You should get those disks because they may have a driver that is needed for this computer that may at least get the network related hardware working again.
Here is what we are going to try next.
First shut down all the computers that are part of this network.
Unplug the power supply from the router, so that it is completely power off.
Reset the modem or power it off for about 5 minutes.
Let everything sit like this for a total of 5 minutes.
Now if you unpluged the modem, plug it back in again.
Allow the modem to establish an Internet connection. The CABLE light should be lit when this is done.
Now lets get your MODEM support pages up here for reference.http://homesupport.cisco.com/en-us/wireless/lbc/BEFCMU10
There is a driver for this modem here. http://homesupport.cisco.com/en-us/wireless/lbc/BEFCMU10
There is also 3 user manuals in .pdf format at that link above.
Here is the user manual for your modem. http://homedownloads.cisco.com/downloads/BEFCMU10-v2_ug.pdf
Now we'll move onto your ROUTER.
Here is a .pdf version of the owners manual here.http://broadband.motorola.com/consumers/pr...anual_US_UK.pdf
You can now power up the router and allow it to communicate with your MODEM.
Once this is done the modem's LINK/ACT light should now flash, meaning the router and it have established a connection to each other. The ROUTERS Internet
light should also be flashing. The send and receive lights should be inactive for now, they will be until the computer is again powered up and communicating with the network, so no need to worry about that at this point.
Now once the Modem and router are finished running their setup and registration communications, it is time to start up one computer, in this case the computer you have a problem with, make sure this is hooked up through a CAT 5 networking cable and plugged into LAN PORT #1. Make sure the RJ-45 plugs on the network cable are not damaged in any way.
Make sure it is securely hooked up to the LAN port on your computer's Ethernet port.
See if it connects to the Internet by opening a web browser, if anything try going to ALL PROGRAMS, ACCESSORIES, SYSTEM TOOLS, and INTERNET EXPLORER (With no add-ons) and use this browser.
We are going to access the ROUTERS setup menus.
I will NOT offer default passwords here even though they are published in the manual, you should know them anyways since you own the equipment. SO that part will be omitted from the following text.
Logging In to the VT2442
1 On a computer connected to the VT2442, open a Web browser.
2 In the Address or Location field, type http://192.168.15.1
and press ENTER.
3 In the Username field, type your user name.
4 In the Password field, type your password.
5 Click Log In to display the HOME page:
Hopefully someone told you to change the default password to one of your own, routers have a default user name and password that everyone knows publicly.
Before I go any further with instructions, I need to ask you if your connection problem at this point has been corrected.
I also need to ask you if you were NOT able to connect to the Internet, were you able to gain access to the routers setup menu by typing that http://192.168.15.1
I will wait for your answers.
