# I fixed my home office Wi-Fi issues using Samsung's free diagnostic tool Mapping signal strength with Connectivity Labs improved my internet in minutes. - **Source:** [Latest news](https://brifing.si/source/77d15218-219f-472d-bf40-31b5646d2942) - **Published:** 2026-07-24 - **Original article:** - **On Brifing:** https://brifing.si/s/7bd1101e-5d14-4779-8cda-a0fabe855a9f ## A long-neglected problem When setting up my home office during COVID, I prioritized feng shui over internet connectivity. But recent performance drops began severely impacting productivity. My ISP's upgrade offer proved insufficient, prompting me to seek alternative solutions. ## Samsung's hidden gem Connectivity Labs on OneUI 6.0+ Galaxy phones provides real-time Wi-Fi heatmaps. Ideal signal ranges between -30 dBm to -50 dBm, while values like -80 dBm indicate serious issues. Enabling it requires simply tapping the version number seven times in settings. ## Revealing signal analysis Tests in my 100 sq ft office showed adequate 2.4GHz coverage but troubling 5GHz performance near my desk (-80 dBm). The cabinet area maintained healthier -40 dBm to -60 dBm readings, suggesting better positioning for high-bandwidth needs. ## Simple yet effective fix Swapping my desk and cabinet locations yielded dramatic improvements - download speeds increased by 100 Mbps and upload by 50 Mbps, matching my Verizon Fios plan. This proved expensive ISP upgrades aren't always necessary for better performance. ## Alternatives for non-Samsung users Ubiquiti's WiFiman app offers comparable features for other devices. The free tool measures signal strength and speed while logging room-by-room data. In some aspects, it surpasses Connectivity Labs with additional functionality for power users. ## User-friendly technical solution Unlike developer tools like Wi-Fi Verbose Logging, Samsung's solution requires no technical expertise. Its intuitive interface helps non-technical users identify signal issues effortlessly. Such tools prove invaluable for remote workers optimizing home networks without professional help. ## Sources covering this story - https://www.zdnet.com/article/samsung-connectivity-labs-wifi-diagnostic-tool-fix-office-setup/ — --- _Summary written by Brifing from the original reporting.
