Folks, I've been volunteered to improve the network system for a church that serves and is located in an impoverished neighborhood.  The primary reason for setting up a network is because the Houston Food Bank now requires all of its food pantry clients to be registered via online web applications.

The problem is that this is a 100 year old church with concrete walls and wifi signals do not penetrate at all.  Comcast came in and installed two Arista access points at $30 per month rent for each, and they just don't work with different SSID's and concrete walls.

I am proposing tossing all the Comcast junk, running 4 or more exterior CAT5e cables from the cable modem to all the rooms used by the food pantry, then installing TP-Link EAP 225 V3's in each room, using POE.  I would use the free Omada software for configuration on these 6 or 7 access points, giving them the same guest and private SSID's so that moving from room to room would be transparent to the user.

A few rooms are upstairs and while the flooring is wooden, the transmission of wifi signals is spotty, sometimes OK, sometimes not good.  Thus, I would use 6 or 7 AP's, for example, one down and one in the room directly above it.

TP-Link is certainly a cost effective solution and would cut at least $80 per month from their Comcast bill.  In a prior life I managed a Meraki MX equipped office so I'm familiar with the networks but not TP-Link.

Does this sound like a feasible solution?  Appreciate any input.

Cheers.
