WiFi breakdown problem with L2TP VPN setting

[ZianYang]

Hi all,

My Macbook Air (Year:2012) cannot connect to my L2TP VPN setting after I upgraded my OS X to the latest version : 10.10.4

Once I connect to the VPN IP, my house Wifi will be unavailable...I have to reboot the router in order to reclaim my Wifi signal.

Anyone has the same problem with me? or any solution on this?

I can't reach out the world without VPN in China. HELP. :/


Note:
1. my VPN setting works on my iPhone.(Also the latest iOS version), just can't use it on my Macbook air.


And this is the first post for me here, any violation or break of rules, please tell, thanks!
