MacBook and MacBook Pro unable to connect to 2WIRE wireless

Category : mac and the internet

I have been unable to connect to the wireless network at home (and only at home) on both Alvin's MacBook and my MacBook Pro. The 12.1" and 14.1" iBooks are fine though. But earlier this year, the Macbook Pro had connected.

So I googled and it seems the culprit may be the AirPort Extreme Update 2007-001; see the MacFixit report.

Workarounds are suggested:

  • Delete all "Preferred Network" listings then re-establish. One surprisingly effective AirPort Base station-specific fix for an inability to connect to wireless networks involves deleting all stored preferred networks, then re-establishing any used listings. Here's the process:
    1. Open System Preferences and select the "Network" pane
    2. Select "AirPort" and click "Configure"
    3. In the "By default, join:" pull-down menu, select "Preferred networks"
    4. Delete the network(s) you regularly use from the list
    5. Launch the "Keychain Access" application located in Applications/Utilities.
    6. Click on the "Kind" filter at the top, and look for "AirPort network password" entries. Delete them.
    7. Restart, or log out then back in.
    8. Repeat steps 1-3, this time re-adding your regularly used AirPort networks to the list using the "+" button.
    9. Restart or log out then back in.
  • Turn "Distribute IP Addresses" off - The problem may be attempted distribution of IP addresses from the AirPort Extreme Base Station, resulting in a conflict with the distribution of IP addresses from the DSL/Cable modem -- a situation which can be fixed by using the AirPort Admin Utility to turn "Distribute IP Addresses" off.
  • Select "Make Changes to existing AirPort Base Station - When you experience an issue where the desired wireless network looks as though it is accessible (through the AirPort menu item or the Internet Connect application), but delivers the message "There was an error joining (name of network), the most commonly successful workaround is to open the AirPort Setup Assistant (located in Applications/Utilities), then click "Make changes to existing AirPort Base Station". You will be prompted for your WEP or WPA password if one exists. After saving the settings -- even if no actual changes were made -- AirPort access is restored in some cases.
  • "Keep Looking for recent networks" - In some cases, selecting "Keep looking for recent networks" in the Network pane of System Preferences can resolve an inability to connect to local networks.
  • Get the update off your Mac - Finally, failing the above, try one of our [MacFixit's] methods for uninstalling AirPort Extreme 2007-001 to restore router/Base station recognition. (I gotta say, this one sounds a little scary!)

I had also read about inserting a "$" before entering the WEP passkey; but didn't try it; had to leave for work; see macosxhints forums.
