Understanding wifi analyzer

It sometimes takes a long time for a webpage to open. Sometimes up to 45 seconds (if I am being frivolous, tell me. It's the only way to learn). My available wifi is 100mbs. I'm getting 110. So I searched the web. Found signal strength. Downloaded and used WiFi Analizer. Siad my signal strength should be somewhere between -30 and -90 dBm. Mine is -23. Is my wifi totally screwed up or is it very good? I can find nowhere anything about a reading below -30.

Normally a WiFi router will broadcast at about -20dbm.  The signal falls off with the square of the distance so the further from the router the weaker the signal.  -27dbm is a very strong signal but your WiFi adapter should handle it without a problem.  The fact that a speedtest shows the expected 100MB is a good indication that you don't have a problem with the WiFi.  You can verify with a ping test:

On a Windows PC:

Search for


right click on Command Prompt and Run As Administrator.



ping  -n  100

Hit Enter.  Wait until it finishes.  Will take a minute or two then it should say:



Ping statistics for
    Packets: Sent = 100, Received = 100, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 20ms, Maximum = 32ms, Average = 23ms



If your WiFi is good you should see Lost = 0 on the second line.  (Numbers on bottom line may vary)


Slow loading Webpages can be caused by too many ads on the page (Get the Ublock Origin extension for your browser, F B Purity extension if Facebook is the problem), too many browser extensions (Go in to Settings on your browser and disable all extensions then restart the browser), Busy CPU ( search for Task Manager and hit Enter then click on More Details.  CPU usage over 50% can cause the browser to be slow), Busy or slow Hard drive(an SSD will make a big difference in how fast a browser loads.  In Task Manager check Disk Usage (should be very low), Low Memory (In Task Manager check Memory usage.  If 50-80 is OK.  More can cause Page faults where the PC has to store data on the hard drive instead of the RAM and that is much slower.).  Try Speedyfox.  http://www.crystalidea.com/speedyfoxIt can speed up Firefox or Chrome things a bit.

Will mark as answered.
