Some users reported networking issues on the latest Mac OS 10.9 Mavericks. I got this tip from my colleague, and it seems to fix the intermittent network problem.
The fix is to create or edit this configuration file /etc/sysctl.conf . Add or edit this line
net.link.ether.inet.arp_unicast_lim=0
If you are familiar with editing the configuration file using vi or emacs, this is all you need to know. If not, here are the step by step instructions:
- Open Terminal in Applications -> Utilities folder.
- Type this command to invoke pico editor. Enter your password to continue.
sudo pico /etc/sysctl.conf - Add or edit this line
net.link.ether.inet.arp_unicast_lim=0
- Press Ctrl+o to save the file. Press enter for confirmation.
- Press Ctrl+x to exit out of the pico editor.
- Reboot the computer.
