Joseph is very knowledgeable concerning all aspects of electronics. He diagnosed the problem quickly and had a myriad of solutions available to solve the issue.
I'd call him first for anything electronic that occurs in the future.

Joseph was fantastic. He quickly diagnosed and fixed the connection issue between my record player, the Sonos app, and my rear speakers that I had been struggling with for a while. He clearly knows his stuff when it comes to audio systems and Sonos setups.
He was professional, efficient, and explained everything in a way that was easy to understand. Within a short time everything was working perfectly and sounding great.
If you need help with home audio troubleshooting, Joseph is the guy to call. Highly recommend.

Joseph of No County WiFi is a Rock Star ! I VERY highly recommend him! He transformed my TV/ speaker living room set up into a significantly improved hometheater - He’s super resourceful, and smart as a whip. I was thrilled with the work he did - updating and improving three different TVs and associated speakers. We were able to utilize a lot of my current Bose speakers which weren’t set up properly! It’s now 1000 percent improved. So he saved me from unnecessarily buying more gear right now. He is also super responsible, reliable and totally professional!! I will be contacting him again to update my master bedroom sound system !! He is also reasonable and responsive…
Thank you Joseph!
