@Manuel_Couto See the section on configuration of your router to specific channels. The channel specification may be the same on V and Z1
Troubleshooting
5 GHz Access Point
If you have a 5GHz WiFi router, the THETA V may not connect to it reliably. You need to limit the channels to 36, 40, 44, or 48. The THETA V complies to the 5GHz standard W52（IEEE 802.11a/n/ac that works with channels 36/40/44/48.
Many 5 GHz routers comply to W58 standard, which allows dynamic channel allocation to include 149/153/157/161.
If your router is using those channels, the THETA V will not connect in client mode. Please refer to this Wikipedia article on WLAN channels.
