I have an AC1200 setup as a LAN (wired) to a Raspberry Pi 4 for access as a music player. I want to connect it wirelessly to my home network (xfinity) which is located in another room (w/extenders). I can not seem to either find the information I need or get it to work. I cannot move my TP-Link setup due to the location of my receiver which my Pi DAC needs to be attached to.

Thouogh I am computer and software savy, I am not IT network savy. I appreciate any information that will help me to accomplish what I am try to do.

Note: It would not allow me to select the proper model number. My router is really a Archer A5 (AC1200)
