Recently I installed a fortiap 231F, I have already created the policy so that it can see my internal network, has enabled all services and has no restriction, when I make a ping to the ip of an internal computer (internal network 60.1 - wifi network 70.2) this works but when I ping the host name fails to find it.

This looks like a DNS problem or the DNS suffix sent by the DHCP server. Are this domain PCs that you are trying to reach with their hostnames?

[SoporteAbetelnet]

No, actually i don't have a domain server 

[ebilcari]

Where are this hostname configured than, do you have a local DNS server in the network or you have configured FGT as the DNS server?

[SoporteAbetelnet]

I configured the FGT as the DNS server

than since you have created a new interface you have to add it as interface in DNS service. If you are using tunnel SSID add the SSID on the list and configure it as the DNS server in DHCP scope "Same as Interface IP" on SSID configuration:
