Hi. I would like some help wit how to test wi fi radiation? I have bought my tester and when I test microwave radio frequencies around a few feet away from the router the reading is insignificant? When I test electromagnetic frequencies I have the same result? Does this mean that the ambient levels are safe?
Any help would be appreciated?

You may have covered these already…… Is wifi definitely enabled on the router? Some routers allow you to disable it – in which case there will be no microwave signal. As confirmation, a wifi enabled laptop will detect networks where the signal level is well below that which would register on a meter. Is your laptop detecting a signal from the router?
Obvious question, but I assume that the meter is definitely working…….
Wifi may still function even if the signal level is below what is normally measured on a meter. I have used a meter which reads down to 0.02 V/M in a classroom with a working wifi router (but no active computers) and there was no visible or audible signal. I would like to repeat the test to be sure, as I found it hard to believe. The router was some distance away, at the far end of the next room.
Wifi signals are not necessarily continuous. You may need to wait several seconds to get a detectable signal from the router. My meter goes silent for several seconds at a a time even when wifi is enabled on our router (PS it is now permanently disabled).
By ‘electromagnetic frequencies’ I assume you mean power frequencies (50 or 60 Hz). I have not found these to be a problem with most computers or routers, provided you are a reasonable distance away from them (say 2-3 feet). But I’m sure that there are exceptions – always worth checking.
