When sharing internet in my Macbook, from a 3G USB pendrive to Wi-Fi, if the 3G connection falls, the natd process rises up in CPU usage.
Is this a real problem? Is it expected in some way?
There's a easy way to solve the hogging, using the menubar disconnect option, but sometimes it doesn't work and I have to unplug the USB modem.
My modem is a HUAWEI E226.
Hope you can help me.
