Re: No Internet With New Router, Computer, or Adapter

This document is relevant if you had an Internet connection, but lost it when: * Adding a router to your network, or * Using a different Ethernet adapter card or computer than the one your ISP used during installation. Use ISP Configuration to see whether you need to "spoof a MAC address" to connect to your ISP. If so, follow the instructions in this document. If the Ethernet card that was used during ISP installation is not available, you may need to register the new Ethernet card's MAC address with your ISP for the following to work. MAC address stands for Media Access Control address (not "Macintosh computer"!), a unique number built into modems, routers and other network hardware. It ensures that one piece of equipment is not mistaken for another one. Some ISPs validate your connection by checking the MAC address of the Ethernet adapter in computer that was registered during ISP installation. If you add a router or change computer or Ethernet adapter, these ISPs will drop your Internet connection, because they find the MAC address of the newly added router or adapter, instead of the one they expect. To fix this, change the router to report the Ethernet adapter's MAC, instead of its own. This is called "spoofing the MAC address". To find a PC's or Macintosh's MAC address, see How to Find an Adapter's MAC address : To Spoof a MAC Address 1. Connect the computer that your ISP's installers used to establish Internet connection to the router. If you are unsure which computer was used, call your ISP, and ask what MAC address was registered. Then, using the instructions in the box below find the computer whose MAC address matches their records. 2. Disconnect other computers from the router. (If you do not want to disconnect other computers, you need to know the adapter's MAC address, as described in the box below. Then, in step 6, type Use This MAC Address, entering the adapter's address.) 3. In an Internet browser type the address 4. Type admin for the username, password for the password, and click OK. 5. Go to the Basic Settings > Router Mac Address. 6. Select Use Computer MAC Address. 7. Click Apply. This automatically gives the router the computer's MAC address. 8. Click Test to make sure you are connected. If you are not connected, contact your ISP.

Motorola 1c743 wireless adapter reset

You modem needs to be powered on, linked to your cable or phone connection, and then linked to your router with an Ethernet cord. You also need a base computer (connected to the router with Ethernet as well) to adjust your router settings, like password and router name, and assure that you are communicating with the Internet.

Install your wireless adapter software to your laptop or computer that will be using the Internet wirelessly.You will be prompted at some point during the installation to plug in the adapter. (If prompted, restart your computer.)

Plug the adapter into your computer or laptop. Some adapters come as USB-compatible (Universal Serial Bus) plug-and-play devices, and others are PCMIA (Personal Computer Memory Card International Association) cards that go into a special wide slot in laptops.

Go to your computer control panel and click on Network Connections when the software download is complete (if the control panel does not load automatically). Your new adapter should be now be listed. Select the icon and look at the description to make sure that it is connected. If not, right-click the adapter icon and click Enable.

Double-click the adapter to search for a wireless connection. Refresh the list of connections available until you find the name of your router. Enter any passwords that you set up for your wireless router and then connect to the Internet.

When the router is connected = no service - when I bypass it I have internet service. How can I perform updates on the router when I connect it I don't have internet service. Connie Tolton

This is a problem with a lot of cable internet providers. The modem binds to the first device it connects to, which would be the computer that you are using. You will have to setup mac cloning in the new router for it to work. Connect everything through the router. On the computer click start then run. Type cmd and press enter. This will open a new window. In this type ipconfig /all. This will list all network devices in your computer. Find the one that says Ethernet adapter Local Area Connection. Find the line that says physical adapter. Write down the address it has listed. It will be something like this 00-26-2D-55-8E-81. It may have this : instead of the dashes. You can then close this window and open internet explorer. type the following addres this will connect you to the router. The default user name and password is admin. You should now be at the main router screen. In the upper middle of that screen you should see mad address clone. Click here then type in the address you wrote down earlier. Save settings. Then close Internet Explorer. After about 3 minutes for the router to reset everything should work.

No Active Internet Connection

If you want to use the wireless portion of your router, you would need a wireless adapter installed on your desktop. If you are getting internet on your desktop then this means that your wired connection is fine to the router is fine. The WMP54G adapter will work with your router, however if you are not planning on connecting to the internet wirelessly through the router then there is no need to purchase the adapter. Hope that this helps you out.

Cannot get internet connection on pc with wireless adapter

The LAN will really tell you that its disconnected since your computer downstairs is not connected with a cable to the router, the only problem here is the wireless PCI adapter is not installed properly, try to run again the setup CD for the adapter and make sure you restart the computer when the installation is complete...

Connecting to internet

Ok, cable (coax) comes in from wall and attaches to modem. Ethernet cable goes from modem to WAN Port of router. You may have to reboot both devices to ensure that your modem (internet service provider) assigns IP address to your router. If PC is close enough, attach new ethernet cable from one of the 4 ports on your router down to your PC's ethernet adapter. (where your modem used to plug into). Router will now assign an IP address to your PC and you should be able to access the www.

Good Luck and let me know if you have any more questions.

Lose wireless connection when the phone rings...

You won't have to buy a new adapter as long as the new router uses the same standard (i.e. 802.11b, g or n).

Drivers 4 Linksys BEFW11S4 ver. 4

Your wired network adapter will talk to a wired router without a driver for the router on your computer. Your wireless adapter likewise will talk to your wireless router without a driver for the wireless router on your computer. Your wired and wireless adapters however do require drivers and the wireless adapter can require configuration. Please provide the manufacturer and model of your computer so I can learn about your wireless adapter and we can work to get it connected to the router.

Do you currently have your router connected to your internet service providers connection and do you have another wired or wireless computer successfully using this device to access the internet?

Can't connect

First if your computer has an ethernet port attempt to connect through the router to the internet with a wire. If that works the next question is did you buy this device new or used? If used we can work to assure we know the configuration of the device. Second what is the manufacturer and model of your computer? Third, if the wireless adapter is not built into the computer what do you know about the make and model of the wireless adapter? Armed with the above information we should be able to resolve the issue.
