Hi svpworld,
The Genos only supports the WiFi standards IEEE802.11 b/g/n, and only on 2.4 GHz (IEEE802.11 n 5 GHz: not compatible!).
Your router may be set up so that it only supports IEEE802.11 n 5 GHz and/or IEEE802.11 ac (which only works with 5 GHz). Then you would have to change the router setting so that at least IEEE802.11 n 2.4 GHz is also supported (Security setting should normally be "WPA2-PSK").
The DHCP server should be activated on the router. As already mentioned, you use the "Infrastructure Mode" on the Genos, and DHCP must of course also be activated here.
Hope this helps,
Chris
