connection problem with my macbook pro

@ bertinoj08

if the DSL light on the modem blinks red or green, it's an indication of a possible line problem...

but since you said that only the INTERNET light blinks red at times, it may be a configuration conflict between your modem and wireless router. BTW, what is your router?

moto3346/moto2210 modems and routers are smart devices. if these modems are connected to a router, it is best to either:

- set modem on bridge mode and let the router handle the internet connection (set on PPPoE)

OR

- set the modem on PPPoE and router on DHCP

hope this helps!

Hello everyone,

I truly appreciate that you took your valuable time to let us know that you are experiencing Internet connection issue  and please accept my sincere apologies for any inconvenience that you might have experienced.

Please, try the following troubleshooting steps as per the issue, which you are experiencing while trying to use AT&T Internet Services.
Basic Troubleshooting:

   1. Verify that all physical connections  to your DSL modem and computer are in place (e.g., phone line, power cords, ethernet cables) and that the power is turned ON. The DSL modem should not be plugged into a surge protector.
   2. Make sure DSL filters  are installed on ALL phone jacks that have telephone devices connected (e.g., phones, fax machines, answering machines).
   3. Make sure the phone line connected to your DSL modem is plugged directly into the phone jack or into the "ADSL HPN" side of a DSL filter.
   4. Powercycle  both your DSL modem and your computer (i.e., turn each off for at least 2 minutes). While the modem is off, remove the phone line from the modem and plug it back in before powering on the modem and computer.

      Note: Connectivity will be lost while performing this step. Please bookmark or print this page for future reference.
   5. If you have followed these steps are still having Internet connection issues, use the AT&T Self-Support Tool to help you resolve the issue or continue with the additional steps, below.

ISSUE TYPE: Connection to the AT&T network is established, but computer is unable to surf (WIRED connection)

Symptoms

    * The "DSL"/"Sync" and "Internet" lights on front of your DSL modem will be in a solid green state.

      Note: It is normal for the "LAN" and "Wireless" lights to flash green when there is an active connection, and these lights will be off when there is no active connection to a computer.
    * Some computers on your home network may be able to surf, and others may not.
    * Computer(s) having connection issues may display a "page cannot be displayed" error in your web browser, or some other indication that you are not currently connected to the internet.

Steps to resolve

   1. Check the physical ethernet connection from the computer to the modem/router. If the connection is correct but the associated LAN light on the front of the modem and the light by the ethernet port on the back of the computer are OFF, try a different ethernet port on the modem/router (if available) and/or a different ethernet cable.
   2. Verify that the LAN connection on the computer is enabled.
   3. Clear the cache  (temporary internet files) in your web browser.
   4. Clear the cookies  in your web browser.
   5. Make sure you are running only one firewall , and consider temporarily disabling your firewall to see if it is causing the connection issue.
   6. Check your system for a virus or for spyware that could be depleting your system resources. Infected computers can generate network traffic without your knowledge and may cause slow surfing speeds. Run anti-virus and anti-spyware software regularly.


ISSUE TYPE: Connection to the AT&T network is established, but computer is unable to surf (WIRELESS connection)

Symptoms

    * The "DSL"/"Sync" and "Internet" lights on front of your DSL modem will be in a solid green state.

      Note: It is normal for the "LAN" and "Wireless" lights to flash green when there is an active connection, and these lights will be off when there is no active connection to a computer.
    * Some computers on your home network may be able to surf, and others may not.
    * Computer(s) having connection issues may display a "page cannot be displayed" error in your web browser, or some other indication that you are not currently connected to the internet.

Steps to resolve:

   1. Check the status of the wireless connection. If an active wireless connection exists, the Wireless light on the front of the modem/router should be ON or flashing. If the light is OFF, this indicates no wireless connection has been established.
   2. Verify that the Wireless LAN connection on the computer is enabled and indicates that you have connection to your wireless network. If unsure, follow these steps  to configure your wireless connection.
   3. If you have wireless security enabled on your router, make sure you have entered the appropriate credentials to connect to that secured wireless connection.
   4. Distance, interference, or obstructions can adversely affect your wireless signal. Follow these simple guidelines for optimal wireless network performance:
          * Place your wireless gateway/router in a central location in your home.
          * Set up your wireless gateway/router at least 3 feet away from other appliances that send wireless signals (e.g. microwave ovens, cordless phones, baby monitors).
          * Avoid physical obstructions (i.e., don't place the wireless gateway/router directly against a wall or within a cabinet)
   5. Clear the cache (temporary internet files) in your web browser
   6. Clear the cookies in your web browser
   7. Make sure you are running only one firewall, and consider temporarily disabling your firewall to see if it is causing the connection issue
   8. Check your system for a virus or for spyware that could be depleting your system resources. Infected computers can generate network traffic without your knowledge and may cause slow surfing speeds. Run anti-virus and anti-spyware software regularly.

Hi everyone,

Additional troubleshooting step that you could try is to change your WEP key to 128-bit encryption which has 26 characters instead of 64-bit encryption which has 10 characters. You will find the steps on how to change your WEP key by clicking on this link:

http://support.2wire.com/?page=view&article=60

Before changing your WEP key, you need to clear first the keychain in your MacBook so that it will ask for the new WEP once you try to connect again. For more information about a WEP key, please click here.

Also, you don't need to worry about the compatibility issue between your 2Wire gateway and the "wireless N" adapter in your MacBook Pro because the N adapter is designed to be backward compatible with our 2Wire gateways.

You may just contact our AT&T eChat help desk for further assistance in doing those steps above. If you are located in AL, FL, GA, KY, LA, MS, NC, SC, & TN, here is the link for AT&T eChat:

that would be a good idea! apple airport express or airport extreme router should work perfectly with your mac "n" adapter since they both came from the same manufacturer. compatibilty issues should be eliminated.
