From March 8, 2023, the WiFi connection is as follows:
- IP: 192.168.8.1  
- WiFi password: mmdvm0000

Package Included:
- 1 x Set of MMDVM Hotspot

Note:
- It supports WiFi, but does not produce a pi-star hotspot. Plug in an Internet cable into the system first, configure the WiFi and then restart. And then you can use the WiFi.

Setup Tutorial:
I. Preparation
1. Things we need: router, simplex router or duplex hotspot board (with USB to TTL chip on the board).
2. The router has been flashed with firmware, and your computer can open the router management page normally.
3. The computer is wired into the LAN, or the computer WIFI is connected to the router hotspot, and the WIFI name is generally: openwrt; password: none. WAN inserts the higher-level route (note that the router modifies the LAN IP address and then inserts the higher-level route).

II. Router Settings
1. The duplex board is connected to the data cable router, and then powered on (required). After 1 minute, RUN will start flashing slowly on the hotspot board.
2. Open 192.168.1.1 on the computer (if not, please see Local Connection), and open the page as follows. Password: password and log in.


3. After logging in, click Manage in the lower right corner, and then click the top network --- interface.


4. Edit at the LAN port and modify the IP of the LAN. Generally, I change it to be: 192.168.8.1. Others remain the same, and then save. The page will close after saving. Click in the lower-right corner of the page: save and apply. The router IP is: 192.168.8.1.


After the saving is completed, you can plug in a network cable in the WAN and connect it to the higher-level router. At this time, it is recommended to restart the router.


III. MMDVM Settings
1. After the router restarts, open the set IP (my IP is 192.168.8.1) and enter the management page. You can set up MMDVM. Click on the station --- Advanced Modes and the page is as follows:


2.Here is the MMDVM setting. Below is a notepad file, the original has some defects, please replace it with the template I sent. The template uses DMR as an example, let's talk about some settings for yourself.

3. After modification, click the lower right corner to save and restart. After a while, the RUN light of the hotspot board will flash fast (when it is just powered on, the RUN light will flash slowly), which means that the hotspot board is working.
4. The following are possible problems:


IV. Connect the router to the the upper WIFI or mobile phone hotspot setting in a wireless way.
1. Click Service - Travelmate to enter the following page. On first use, it executes the Interface Wizard once. Save it in the wizard, save it again after it comes out and apply it.

2. Add wireless site after saving and applying. Click the wireless site on the page (also in the Service). Click Scan.....scan wireless network--- add network---- enter network information---- save----- save and apply. You can also add multiple wireless networks here.

3. Wireless is disabled when it is first added. Enter the network --- Wireless --- Enabled. In this way, it can connect to the network normally.
