In addition you could check internet speed with a network speed test as well to compare wireless and wired connectivity. It’ll then measure the performance of your CPU when performing everyday tasks designed. You can run a WiFi speed test on all your devices to idenitify the ones that have a strong WiFi signal and the ones that don't. Simply open the app, close any other apps that might be running on your Mac, and click ‘Run CPU benchmark’. Selectively enabling and disabling your WiFi hotspots can quickly help identify the problematic device. Whats a Benchmark Benchmarks are tests that measure the performance of a computers processor, memory and graphics card. Maybe your device is not connecting to the correct WiFi hotspot, so it must go through a thick wall. If the interet speeds differ on your connected devices, however, the poor connectivity is likely either due to a local misconfiguration or device capabilities. If the internet speeds are the same for the weak and strong signal, it's likely an ISP issue. Just run multiple tests, one close to your WiFi Hotspot and one in the place where you're having issues because the signal strength diminishes. So to figure out if your connectivity issues are due to your ISP, your wireless connection or a local router issue running a WiFi Speed Test will give you the insights you're looking for. Most of the devices on your home network today are not connected with a wired connection anymore. If the CPUSpeedLimit indicator is less than 100, this means your Mac automatically throttled the CPU. Launch Terminal and run the pmset -g thermlog command. Running a WiFi Speed Test is the right solution for most people if they encounter connectivity issues as they are usually internet speed related. You can also check if your device has already limited the CPU clock speed.
