Bridge mode lets your router connect to multiple networks at once, allowing devices to communicate between them.

I've been using my ISP's router with the WiFi disabled and connected via Ethernet to my Asus RT88u. It provides a stronger signal throughout my home. My friend suggested switching to Bridge Mode for better performance. Now I see an option labeled "bridge mode/router only" in the settings, but I'm not sure what Bridge Mode actually does or why it's beneficial.
Bridge mode functions similarly to passthrough, sending all WAN traffic straight to your router. Your ISP gateway operates as a modem-only device, even though the menu suggests otherwise. If you're not using bridge mode, you're double-NATed, meaning your gateway runs a DHCP server and gives private IPs to your router. Your router will also manage DHCP and assign IPs to connected devices. Double NAT can lead to issues, which is why passthrough is advised for dedicated routers. Your router displays the public IP and remains reachable from the Internet. Bridge mode turns off firewalls and security features on the ISP gateway, so verify your router settings carefully.
Bridge mode connects two devices together, treating them as one unit. It works similarly to adding a modem to your router.
It might be linked to the IP configuration issue you're experiencing, which can cause temporary disruptions in your internet connection.
Similar to what others have noted, enabling bridged mode also assists in hosting a remotely reachable file server, game server, or email server. Simply opening ports on your router becomes ineffective when it’s behind another router. This becomes a challenge with double NAT. It can be addressed, but there’s no need to find work around it if you opt for bridged mode directly.
