Apologies if this has already been covered, but the 'standard' 2-cable way to get stats from a modem in bridge mode is this: https://kitz.co.uk/routers/zyxel_VMG8324-B10A_bridge.htm#linestats
It's a different modem of course, but the principle is the same.
That is the guide I followed but cannot seem to get it to work correctly. It is probably something really simple that I have missed.
I was also looking at Chrysalis post in another thread which suggests the following:
1 - login to UI of zyxel
2 - select networks -> vlan groups
3 - add group called bridge set vland id to 2, tick the include box on the lan port you want to use. (one used for wan)
4 - select networks -> interface grouping and assign bridge vdsl port to same lan port.
Note you may have already done steps 3 and 4 when setting up the bridge.
5 - now select networks -> home networking
6 - in group name box default is preselected, change this to bridge
7 - make a note of the ip address shown, change if you want to. (to keep things simple change it to 192.168.2.10 and make sure your old modem is not connected so no conflict).
I'm a bit unsure on points 2,3 and 4 as I can't see anything referring to Vlan groups? Possibly worded differently. I may need an idiots guide.
