If any of you are Cricket wireless modem users, you know there is a huge problem with the software you download from their support site. When I first used it, my Activity Monitor was reading an average of 85% CPU usage on both cores! This is completely unacceptable for any reason, so before I returned the USB modem they provide, I figured out the following little trick. Having done this, my CPU load is now under 2% on my 2.4GHz iMac.

The software to control your internet access is not doing anything than setting up a VPN, and they can get away with such poorly written programs because the download installs a modem script. So, once you have the script, why not give that software the slip?

Here's what I did:

  1. Download and install the software on your Mac. You want to make sure that the modem is going to properly connect to the internet in the first place.
  2. Go to System Preferences » Network, and add a VPN.
  3. Choose L2PTP over IPSec as the type, and name it.
  4. Your config will be Default, your telephone number is #777 (yes, even yours), your Account Name will be your real modem's phone number (which is located on your reciept, and the info was part of your install of the other software), followed by
  5. Your password is your phone number minus the area code, i.e. your "7-digit" number. You're almost done, but this is the area where your might break your connectivity if you choose the wrong settings.
  6. Click Advanced, and set up the tabs as follows: Click OK in the Advanced window, and then select the 'Show Modem Status in Menu Bar,' and you're home free!
Now you can avoid the CPU load (and advertisements in the Cricket software), and use your modem right.
