Adding TP Link 1750 (Archer A7) to an existing mesh network?
I have been enjoying a TP-Link Deco M5 mesh network (3 units) in my home for the past 10 months. But I am starting to miss some of the capabilities of my old router, namely (a) having a USB port for putting a big fat storage device on my home network and (b) having more than one fast RJ45 ethernet ports available.
I purchased a TP Link 1750 (Archer A7) to satisfy this need but I see 2 possible options but not sure which is best.
Option 1: Router mode
Make the Archer A7 the primary router. Attach NAS drive to the router and the Roku. Extend the mesh network with my 3 existing Deco M5 units throughout the home.
Question: Is the Archer A7 mesh network compatible with the TP-Link Deco M5 devices?
Option 2: Switch mode
Keep my current Deco M5 mesh network in place an use the Archer A7 as a switch. Connect the Archer A7 via CAT5 to the lead Deco unit and use it as a switch to drive the NAS function and any other hardwired devices such as the Roku.
Let me know if you see any other options.
Thanks in advance.
