Hi - just moved into a new house and brought my EERO network with me - wireless setup works well so no issues there. However I've built an office in the garden which has a second wired connection to it (different port from the same router) and I cannot get it to work with the newest EERO purchased. I believe this is due to EERO not liking two wired connections which it sees as Gateways - when I try it there is basically a conflict and I end up with either good speeds (wired) in the office outside and rubbish ones indoors or vice versa. Having read through about how to resolve this I think the following switches are needed but am unsure where they fit within the topology - does anyone have a similar set up which they can comment about please? (Thank you)

Complete novice at this but the bit that is confusing me is how to get a connection out to the office so that I can then create a wired connection to PS5, laptop etc. (i.e. can you have multiple wired connections on a single EERO network?)
