WM mobile app "network connection failed. Please try again"

When I used the QQ synchronization assistant last night, I found that the prompt "network connection failed, please try again". Finally, Google recorded the cause:

Start → set → connect → advanced → select Network;

Then you will see twoProgramWhen automatically connecting to the Internet, use: "and" when the program automatically connects to the private networkUse :"...The problem is here !!!

Solution: Check the network that you used when you reported "network connection failure". Set it to another network and try again. Don't you understand?

[Note] my mobile phone is an HTC s900, wm6.1 system, and the network "Internet Settings" and "WAP" are used ".
