With mac address filtering just make sure your useing the correct mac addresses. this is better than wep. dont go by the box. go to start -> cmd -> and type ipconfig then look for the wireless connection and use that to be a 100% correct. have encryption turned off if you have it turned on and once all are connected then turn it back on if you like, but theres no reason because no two devices that share the same mac address. if you are certain that you have the correct mac addresses listed then you will need to replace the router. remember there soho and made cheap so every now and then a bad one will pop up.

How to use my wifi?


Hi, Thanks for using fixya

You don't need any software.

Log into the router with a web browser (you can do that with an Airpor Express, right?), and look for a list of connected systems. You'll see MAC addresses (that's the machine's network adapter address, not something related to Mac computers). You should only see the number of devices you know YOU connected, so based on your questions, that would be your computer and your DS.

Here's the problem: how's he going to connect if he doesn't have the WEP key? Unless he's very computer savvy, he's not going to be able to guess it, especially if you randomize it.

There are ways to check the MAC addresses on your equipment. The DS might have it printed on a label on the outside of the device. There are commands you can give the computer to get the address (I don't know what you're using, and if it's a Mac, I *really* won't know). Once you get those addresses, check them against the list of connected systems. if there's something there you didn't connect, that's the one.

However, I doubt he's connecting if he doesn't have the key.What evidence do you have that he's doing this?

Hope this helps

Error:111 No internet connection error followed the exact instruction multiple times and same error. Help please and thank you in advance.


John:
Most likely you will need to disconnect the power cord from your modem for 15 to 20 minutes in order to clear the MAC address of the computer/device that was previously connected to it.


After the modem has been unplugged from power for 15 to 20 minutes, plug it back in and it should then recognize the router as its new MAC address to assign an IP address.


This will probably restore your access to the Internet.

1. This error is related to the dialup modem
you will need to disable the dialup modem.
When setting up your router for the lan in the browser you will need to select "internet connect that is always on"
DNS should be on "automatically assign.
yes you can connect a switch to the router and the router will assign each port an IP address automatically.
If you are using the router wirelessly you will need to assign each device that is wireless via the MAC (Media Access Contro) number.
Check you router manual for details on how to set each device in the router by MAC address.
Basic instruction for multiple units set up in the router
Basic setup for multiple computer to go online:
1. power router off
2.connect all computers you want to connect.
3. start computers one at a time completely
4. check router for status light per computer to see if device is seen by router.
5. open web page to see if each computer is online.
7. Do ipconfig / release/renew if not connected.

Try using the MAC address of the ethernet adapter and clone it to your router. Your ISP might be recognizing the MAC address of the LAN card of the computer.

To get the mac address of the computer go to the command prompt and type ipconfig/all.

You may also need to contact your ISP to clear arp in their end, so that they will detect that you have a router. I hope this helps!

(you may have to scroll up and down to see all the data)

You will see all your network connections (wired and wireless). Yes, the physical address is your MAC address. Make sure to grab the wireless one.

Hope this helps.

Cannot connect the 2nd computer to the internet using the ethernet adapter


Most likely, your ISP only allows a single MAC address to connect to them. To make this work with multiple computers you'll need a router that can do MAC address cloning, i.e. it reads the MAC address off of the computer that works and presents this to the ISP in all cases even when the request comes from different MAC address.

The MAC address is unique and set at the factory for each ethernet card so it's not something you can or should attempt to change. If you were able to change the MAC address on the second computer to match the first you would break your network rather than fix the problem.

It is also possible that you are using fixed ip addresses and simply need to configure the NIC on the new computer. If you check the IP v4 settings for the old computer and they have an explicit address for the card then this is is the issue. If so, simply configure the new computer to match the old computer but make sure the last of the four numbers in the ip address is something between 1 and 254 that does not match the first computer or the gateway address.

I have the same problem too


Try this procedure:

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.
  3. (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.)
  4. In an Internet browser type the address 192.168.0.1.
  5. Type admin for the username, password for the password, and click OK.
  6. Go to the Basic Settings > Router Mac Address.
  7. Select Use Computer MAC Address.
  8. Click Apply. This automatically gives the router the computer's MAC address.
  9. Click Test to make sure you are connected. If you are not connected, contact your ISP.

Connecting to a macbook


Hi.

This is all what you just need to do. You need to get you mac address first and edit it using a computer that is currently connect to your router as you are using Mac filtering. To check your mac address :

To find the serial number located on the computer If the MacBook is not turned on, you can open the computer's battery bay to find the serial number.
The MacBook serial number and Ethernet ID (also called a MAC address) are located on the bottom of the computer, underneath the battery, in the battery bay.

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 : http://www.fixya.com/ThreadView.aspx?prdid=252225&thid=102075. 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 192.168.0.1. 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.
