Internet sharing not working
Hi,
My macbook pro 2011 is connected to internet using AX226 wimax modem. I used to share this connection with other mobile devices through wi-fi in all OS X from 10.6 to 10.9. However, in Yosemite, the devices can connect to the shared wifi network, but don't receive any internet connection. For experiment, I tried disabling the firewall with no luck. It seems something is blocking the internet connection, but my limited expertise is no good to detect it. How to solve this issue?
MacBook Pro, OS X Yosemite (10.10.5)
