My current router/modem, when I enable the 2.4GHz Wi-Fi at 100% power, on this tester, only register -40dBm. It appears that there are a number of wireless routers/modems near my home, that this tester shows upwards of -50dBm.
Is this expected? I ask because I am concerned with all these devices having such significant power levels within my home.
You have your perspective upside down. The -50 dBm signal is a less powerful (weaker) signal than the -40 dBm signal. Often when standing right adjacent to a router, the measured signal power is in the -20 to -25 dBm range.
