Hello, I can't configure the router as an access point. I have an Ethernet cable from my main router and I plug it into the C60's internet socket. 
In the configuration, there's no option for the access point. 
I've already looked at the topic, but it suggests a solution that doesn't exist in the C60 v2 (access point option doesn't exist):

Can you help me? Thank you for your understanding.
