Mesh - Bridge Mode? What is it?

So if you're plugging a Mesh "router" into your ISP's router, you turn the ISP's Router's wifi off, and then the Mesh unit takes over all things wifi.

HOWEVER, I'm somewhat confused about "Bridge Mode". I'm guessing with the above setup, you would have the mesh router in "Bridge Mode" as you're letting the ISP's router control IP addresses and the like?

Have I understood that correctly? I've read a few descriptions and I've failed to come to a clear understanding.

If I have understood it correctly, the question is, why would anyone not be using "Bridge Mode" as surely most folks do plug them into an ISP's router which offers the internet connection?

Leaving the ISP provided router in place is always going to be a second best option unless it has a 'modem' mode.

This is the main reason that there's still a demand for the old Openreach provided VDSL modems.

In my case we're talking about s Sky Q Router.

Is my understanding correct btw? To stop two routers fighting and confused who's in charge, you set the mesh router to bridge mode.

Possibly. Terminology varies so it's best to read the instructions (not saying you haven't).

I'd usually think of putting the ISP's router into bridge mode so that it passes the WAN IP through to the device connected behind it (basically acting as a modem). Unfortunately, most ISP provided routers don't offer this.

To have the attached router handle wireless only I'd be looking for an AP (Access Point) mode.

What you're mainly trying to avoid is double NAT.

Without knowing which mesh system you're talking about and having the opportunity to read the manual it's difficult to be sure.
