Linksys mesh system router set up

[OxMooro]

Just had latest EE router installed 

Previously with Virgin Media I was able to set their router to modem  mode.

i could use my 3 node lynksys mesh system 

how do I configure things in this  scenario

@OxMooro   It would help to know what EE Service you have purchased.

The EE Routers cannot be put in router mode, but if you have full fibre and your mesh system supports PPOE you could connect it directly to the ONT if you have one.
