Hi there,

I am having problems connecting a Dell laptop to an Internet connection used by my Dell laptop.

I have a Motorola SB4200 cable modem and a Safecom SWBR-5400 wireless cable router. I have connected the modem to the WAN port on the router with patch cable that was supplied with the router.

However, the Desktop doesn't recognise the router and doesn't detect that it is connected, although the lights that flash on the router suggest that it is working.

The laptop detects the router through a WiFi card that is in the laptop itself. However, although connected to the network, I can't ping any sites with the laptop. I can access the router configuration page from the laptop but NOT the desktop (the desktop doesn't have a network card in it). I have tried keying in the MAC address of the modem on the configuration page and also the MAC address of the WiFi card but to no avail.

What can I do to share the net connection between the desktop and the laptop? The net connection works fine on the desktop even though the router is connected to the modem through the patch cable.

Thanks in advance.

Michael.

If the desktop does not have a network card, then how is it getting internet access? I assume that you have it connected via USB cable. If that is the case, then the modem will only connect through usb or ethernet, but not both. My suggestion would be to purchase a cheap pci network card.

Power off the cable modem, router and all PC's.

Power up the cable modem, wait 4 minutes.
Power up the router, wait 4 minutes.
Power up each PC and see if you have connections.

If you do not have an internet connection, on each machine do the following:

Start, Run, type "cmd", type "ipconfig /all >C:\ipconfig.txt". Leave out the quotes ("").

Open C:\ipconfig.txt with Notepad and copy/paste the info back for review and comment.

There is now a connection on the laptop but no connection on the desktop.

The IP of the desktop has been changed and I don't think my ISP will allow that.

The IPConfig log on the laptop is:

How can I renew the connection to the desktop and maintain the laptop connection also?

Thanks.

A few comments:

Just in case I am not follow this, you have the desktop connected to the cable modem via USB and the router connected to the cable modem Ethernet connection?

Anyway, here is my suggestion, connect the desktop to the router via Ethernet. You may or may not be able to connect via USB and Ethernet on the cable modem. I would probably say it is not the best approach to try even if it does work. If your desktop does not have an Ethernet port, you can get PCI USB cards for under $15.

The other comment is you have the DOG Intel(R) PRO/Wireless 2200BG card in your laptop. Intel did a really bad job with the drivers for most of their Wireless cards and you may need to update the your software if you are having disconnects and connection speed issues.

Intel Support

Get your desktop connected via Ehternet and you will be in much better shape.

Hi James,

Yes, the modem is connected to the PC via USB cable. The router was supplied with a patch cable that goes from the WAN port on the router to the modem.

When the laptop was able to access the Internet, the Desktop was not. The IP of the connection was changed and I've had to reboot my modem to have any luck in getting back online on the desktop.

Thanks for your advice so far.

Are PCI USB wireless cards easy to fit? How do you do it? Would it be easier getting a technician out to do it?

What kind do you recommend?

Thanks.

If your desktop will be close to the router, I would go wired.

As for PCI card installation, fairly easy if you can handle a screw driver. Everything should be Plug & Play (Plug & Pray!!). Power PC off, remove power cord, open cover, remove PCI blank, install PCI card, close case, Pop the drive CD in and away your go.

If you are not willing to get inside the computer, you could go with as USB wireless adapter.

Note, my opinon of wireless: Use as a temporary convienance, not as a permanent solution!

Hi James,

Thanks for the reply. Yes, the Desktop is close to the router. How do we all go wired?

Basically, it is my Dad who has the laptop and he wants to be able to access the Net at any time from anywhere in the house.. He has the wireless card but I would have to buy a USB wireless adapter for my Desktop in order to go wireless. The modem would stay connected to my machine as that's where the broadband box is on the wall.

Thanks for your help so far. I am a complete newbie at this, so I will need things explaining simply.

Cheers.

Here are a few suggestions:

This should be on sale?? for $14.99?? Linksys NIC

D-Link NIC

You could shop around a bit, sometimes you can find these for as little as $5 if you check the local computer stores.

PCI Plug & Pray as long as you can use a screw driver.

Before you spend the money, make sure your desktop does not have an Ethernert adapter or on board Ethernet connection. You may need to look very closely?

For your desktop, do the following to be sure you do not have an ethernet connection:

Start, Run, type "cmd", type "ipconfig /all >C:\ipconfig.txt". Leave out the quotes ("").

Open C:\ipconfig.txt with Notepad and copy/paste the info back for review and comment.

If you have a router, the ONLY connection to the cable modem should be the Ethernet cable to the WAN port of the router. You are making your life difficult by attempting to use the USB connection.

Michael,

No need to buy anything or open the computer. You just need a standard Ethernet cable because your PC already has a Ethernet port as shown by the ipconfig /all command!

From your last post:

Ethernet adapter Local Area Connection:



Media State . . . . . . . . . . . : Media disconnected

Description . . . . . . . . . . . : Intel(R) PRO/100 VE Network Connection

Physical Address. . . . . . . . . : 00-12-3F-93-11-F5


Which is most likely an on board connector, not a PCI expansion card.

Time for an Ethernet cable and get rid of the USB connection!

Radio Shack Ethernet Cable

Home Depot and Lowes has them as well.

There is a network cable slot at the back of the PC.

When we bought the router, it came with a connection cable. I don't know whether this is the one but it fits into the ethernet port on the modem and into the WAN port of the router.

We bought RJ45 patch cable too.

How are these all connected? How can the modem 'talk' with the computer if an ethernet cable goes from the back of the computer into the router?

Can you explain how to fit everything together please?

Thanks.

DO NOT USE THE USB CONNECTION!

Cable modem connects to Router WAN port with an Ethernet cable.
Desktop PC connects to Router LAN port with an Ethernet cable, any one of the 4 ports.
You should see link and activity LED light up and start blinking, this is good.
See of you can get an Internet connection, may take 1-2 minutes.

If you do not get an Internet connection, power off the cable modem, router and PC.

Power up the cable modem, wait 4 minutes.
Power up the router, wait 4 minutes.
Power up the PC, wait for it to boot and try to access the internet.

If you have problems, before you fall back to USB, do the following again:

Start, Run, type "cmd", type "ipconfig /all >C:\ipconfig.txt". Leave out the quotes ("").

Open C:\ipconfig.txt with Notepad and copy/paste the info back for review and comment.

If you fall back to USB and things do not work. Power off the PC and cable modem.

Power up the cable modem, wait 4 minutes.
Power up the PC, wait for it to boot and try to access the internet.

Hi James,

OK, we are now sharing the Net connection between the two machines without a USB cable.

Browsing is OK but has become a lot slower than it was previously.

Is there any way to speed it up?

Should I go to the Intel site and update the drivers for each Ethernet adapter?

Just out of interest, my IPConfig log on the Desktop is now:

Thanks very much for all your help.

First try a download speed test and see what your results are. Choose a location close to you for best results.

Speed Test

Adding the router should not really slow things down, unless there is bottle neck in the router or the interface between the router and the modem.

You may want to try the same speed test download with and without the router to see if there is a difference.

Second try Windows Update and select Custom. See if there are any hardware updates for Network Interface. If you find something for the Network Interface under Hardware updates, I would select and install.

Do not do anything else until you can determine how much slower your connection is and if it is really related to your router installation.
