I have an Archer A7 at home and I have no issues with. We also use a single TP-Link AC750 WiFi Extender for a part of the house that otherwise has a weaker signal.
Recently, we started using Frontier for fiber and they gave us a free eero Pro 6E. Now, I have a choice to either:
a) sell the eero Pro 6E on ebay (can get around $100)
b) replace the Archer A7 with the eero Pro 6E
I am figuring the “cost” of eero is essentially what I can get for it if I sold it, so my question is: Does the eero Pro 6E do anything better than the Archer A7 that would be worth $100 to upgrade?
So, the common sense part of me says… Don’t fix what isn’t broken and use the A7.
The /r/HomeNetworking side of me says, if you have 6/6e end-user equipment, test the Eero 6e equipment.
Then again… I’d have installed OpenWrt on the A7 already.
