Best Ground-mounted System Services in San Jose CA

I wish I had found Regent5 sooner.  After years of struggling with a cobbled-together home tech system that never worked right plus several failed attempts by other companies to diagnose and fix it all, I finally got an answer and a solution from Regent5.  They fixed slow/intermittent internet, weak WiFi, an improperly configured security camera system, a Sonos system that was mickey-moused together in a way that barely worked, and a few other critical things.  They tested wiring, speeds, and settings, replaced what needed to be re-done (including sending someone up in the attic to run wires), set up the network, security system, home audio, and configured everything to work properly.  They brought everything with them on install day (they purchased the equipment based on a detailed upfront evaluation) and explained exactly what they were doing at every step. No up-sell or pressure.  The price was reasonable given their expertise and professionalism and they were absolutely top-notch all around. I will be working with them again on some extensions.  These guys do home wiring/networking, computer configurations, backup systems, connectivity, everything to do with home security and camera security systems, home theater, audio (indoors and out), WiFi, ... THEY EVEN CALL COMCAST SO I DON'T HAVE TO... and every kind of home automation you can think of.  And, bonus, they take privacy and security seriously and made some smart recommendations on that front.  They fixed everything on my list and explained what/why so I can be self-sufficient with settings.  Total pros with a vetted and carefully trained team.
