For the case of inaccessibility, in most cases the browser has done a domain name to the external network to go, please use Chrome or Firefox. Or use http: // MMDVM hotspot IP address / direct access. There are two ways to get an IP address:

1 Log in to the router to check the terminal of the network cable and check the IP address of the device named pi-star

2 Use the [Auxiliary Tools] on the back of the article to view the IP address of the device named pi-star and start to configure the call sign and DMR-ID.
Here, I set the default DMR and YSF two modes, to facilitate testing, please only keep one and your hand the same model
