Hello folks -

Needed some advice on how fix a dead spot in one of my rooms.

I have an Archer AX73 wifi router (in my upper floor living room) that is connected via LAN to my ISP's fiber modem (which is in the garage).    I have a couple of RE305s and a RE505X, which provide a stable mesh network throughout the house.

However, i am having a problem in my office - specifically, in the corner where my workstation is set up.   I need to daisy-chain 2 extenders to get coverage here and the speeds are horrendous (I have been trying to download 350GB worth of images from my cloud account and in the past 24 hours, i have only gotten 70GB done).    Streaming music to the  system in this room is also laggy, frequently freezing up (which never happens elsewhere in the house).

There is a LAN cable wired into this room, that goes to the garage. What i want to do is this:

- attach a second router to this LAN cable, which is connected to my fiber modem on the other end

- have the network broadcast by this router become a part of that OneMesh network in the house

I know it is not possible to have a TP-Link router form a *wireless* link with another TP-Link router using OneMesh - but what about a second wired router?       Would one of the Deco routers, such as Deco M4, do the job?

(I cannot run a LAN cable from my AX73 router upstairs to the office without redoing all the internal wiring, which is not an option right now)

TIA!
