Computers running any distribution of Linux with the 2.6 kernel have been found to experience connectivity slowness to the ResNet network. If you are experiencing unstable network access, follow these steps to apply a fix:

1. As superuser, edit the rc.local file using a text editor like emacs or vim in a terminal. This file is usually /etc/rd.d/rc.local in Red Hat or /etc/rc.local for Ubuntu. This file should be similarly located in other Linux distributions.
   
2. replace the line with exit 0 at the end of the file with:
   

   echo 1 > /proc/sys/net/ipv4/neigh/eth0/locktime

3. Save the file and restart your computer. The fix will now be applied on every system startup.
