ahoi together,


i´ve tested this and worked for me:


1. dissable the IPv6 function in the networktab of the preferences pane

2. download the small app Lingon for 10.5.x here




in the Lingon app click "New" and choose "Users Daemons".

name the rule like you want in the first box.

fill the following command in the second box:


sysctl -w net.inet.tcp.delayed_ack=0


Finally you need to check the option:

"Run it when it is loaded by the system (at startup or login).


Save & reboot ;-)


to check if it´s running you can fire up your terminal and check it with this command:


sudo sysctl -w net.inet.tcp.delayed_ack=0


if you get this line:


net.inet.tcp.delayed_ack: 0 -> 0


it´s working, man


if you get 3 -> 0


you have done something wrong, dude :-(



this small app Lingon is one of my favorite, because you can choose terminal commands as you want !! really nicy !!


hope it works on your rigs, too !!!

tell me your increases .....

This is good. I think this fix is included in kalyway's 10.5.2 install. With my broadcom card I get unbelievable reception (5 out of 5) and unbelievable speed. The same signal on my windows machine and previous OSX installs was only 2 bars.

You don't need lingon. You go to terminal and do this:


sudo -s
nano /etc/sysctl.conf

add the following




Y <enter>



reboot and it will be set every time you startup

Most likely you don't have the /etc/sysctl.conf so it will be created.


and there are many other tcp/ip settings you can change which speedup osx tcpip, many resources on the internet
