I saw an interesting question recently that I thought I would offer up an answer to:
In Windows 'netsh wlan show interfaces', what does the signal % mean?
Here is an example (I have two wireless interfaces on my system - Wi-Fi is the built in wireless adapter, and Wi-Fi4 is an external adapter - cheap - literally $8 from Amazon):
Windows (for some obscure reason) reports the signal level as a percent, not as actual dBm. We have found various resources on the Internet that report there is a rough formula for this % to convert it to dBm. The formula is:
(% number / 2) - 100 = dBm
Here is a resulting chart:
|100%||-50dBm or better|
|10%||-95dBm or worse|
Hope this helps. You can find other interesting Windows and Wi-Fi articles and tips by selecting the tags below.
