My 64 YO house has metal lath and plaster interior and exterior walls so it's a lot like a Faraday cage for both Cell and WIFI. To date I've lived with the cell limits but am looking at adding a high gain antenna/retransmitter inside to fix that now that I'm at home more. Understand the tech and just need to decide it's worth it. For WIFI, commercial wireless access points (WAPs) are overkill so I've been reconfiguring Linksys wireless routers as WAPs, hard running CAT6 to them and have 3 in the house (office/modem location) public areas and my bedroom) which gives me decent wireless coverage with a few drop outs. Wireless to wireless extenders are not really an option as it limits severely location of access points.
Saw an ad for Google WIFI, a set of 3 WAPS that can be used as wireless extenders or can be wired with Cat (after initial configuration) for a seamless wireless environment. Self configuring, etc. Cheaper than 3 GB wireless routers but with a catch. Google pushes upgrades and the Q&As seem to imply that they frequently break stuff when they do. In addition, they push them when they want to and you can't schedule them. Also have to wonder what data collection google is doing behind the scenes (for quality assurance and to provide a better user experience, I'm sure....).
Any thoughts? Inviting big Alphabet into the house or with GMail, Chrome, search, Maps, has that ship sailed?
