Do you have right configuration on windows?I think it's very bother to set this function.I prefer use third-party program.

I suggest you find a app called "es explorer" to have a try.

You can check the DHCP client list on your main router,and you can find the IP of 710,every device connect the main router are on this list.Find the mac address of 710,then you know the IP of 710....

I suggest you contact your retailer to ask for help.

First I suggest you change a SSID,encryption and fix a channle to see if it works. Second you should fix the LAN IP of 702 to avoid the IP conficts problem.

I find that a beta firmware are released on the website,you can have a try.
