Support for this mode started with release 2021.6. The initial setup can be done by following the steps below.

1. Go to the menu.
2. Scroll down to the section for the first, second or third wireless module (your choice). For example, wireless eth2.
3. From the Wireless Mode dropdown menu, select Media Bridge. After doing this, WAN options will be hidden.
   Now, configure settings there as follows:
   
4. Set Wireless Network Mode to: Auto (all possible WiFi protocols).
5. Set SSID to: Whichever SSID you want to use (prefer one with least interference).
6. Set Channel to: Whichever WiFi channel you want to use.
7. Set Channel Width to: 20 MHz, 40 MHz or 80 MHz (your choice).
8. Set Security to: WPAx (Usually WPA2 Personal for home users/small, informal offices).
9. Set Encryption to: AES.
10. Set Shared Key to: WiFi password you want to use.
11. Set Group Key Renewal to: 3600 seconds

In the Network menu, in the LAN Settings section:

• Configure bridge “br0” with an IP Address within the LAN you want to connect to. (For example: 192.168.1.50).
• Configure an appropriate Default Gateway. In our example: 192.168.1.1 (assuming main router has address: 192.168.1.1).
• Enter a Static DNS value of: 192.168.1.1 (assuming your main router has address: 192.168.1.1).
• Starting with release 2022.6, you can select the “Automatic IP” option and your router should obtain the IP/Gateway/DNS via DHCP.

Some advantages of media bridge (MB) mode compared to wireless Ethernet bridge mode include:

• MB mode will work with SDK7 ARM routers like the AC3200 / R8000 (wireless Ethernet bridge is not working/not possible).
• MB mode will work with SDK6 MIPS routers like the Asus RT-AC66U, D‑Link DIR‑865L, (wireless Ethernet bridge mode is not working/not possible).
• MB mode will work with SDK6 arm routers like Asus RT-AC68U, Netgear R7000. (wireless Ethernet bridge mode is also possible).
• IPv4 and IPv6 communication will work (wireless Ethernet bridge allows only IPv4. An except is SDK6 ARM dual-core will allow IPv6).

Note: It is advised to refrain from using 'virtual interfaces' when in Media Bridge mode.

In case of possible issues (like “Losing Connectivity”):

1) Please try to lower the Wireless Client connection check time (affects Media Bridge Mode, Wireless Client Mode and Wireless Ethernet Bridge Mode).

Currently we have the check every 30 sec (default). The FT user can adjust the check value manually, for example set it to 15 sec (see below).

2) Additional improvement - upgrade to FreshTomato 2023.4 (and newer)
