EAP225 Shows much lower signal strength then all connected devices
EAP225 Shows much lower signal strength then all connected devices

Model: EAP225-Outdoor  
Hardware Version:
Firmware Version: 1.7.0 Build 20200113 Rel. 35383

So I recently installed a EAP225 outdoor.   I am waiting for my EAP225 V3 AC1530's to come in before I completely migrate to the new system.  However in my initial testing, all of the test devices (several iphones, a mac book pro and a couple of windows lap tops ) all show full signal strength.  However, when I look at the client list in my Omada Controller dashboard all the connected devices show poor signal strength (less than -75).

 

Now the conspiracy theorist in me says the device manufactureres want the buyers to theink the devices work great, and the AP manufactureres want to sell more access points. 

 

Is anyone else seeing this?  I would imagine this would effect how one sets up RSSI thresholds and how phones get stuck when roaming.

What you see in Omada controller is the RSSI of the client.

 

What you see on your client is the RSSI of the EAP, which usually has a better signal strength than clients produce with their built-in »antennas« (a small piece of metal).

Hello @Reef-a-Holic,

 

Personally, I'm not much of a conspiracy theorist.  Keep in mind that signal bars don't really mean anything.  Vendors can map the number of bars to any RSSI values they want.  Just as they do with cellular signal bars.  In particular on most apple products there are only 3 Wifi bars.  iPhone used to have 5 cellular bars, but now only have 4.  Speed, reliability, and latency are all that really matter. 

 

That said, I'm not sure how much vendors really "calibrate" these signal levels (dbm, mW, RSSI, etc.) so it's possible that different devices will display slight different signal levels even when the underlying signal values (vs. Bars) are being compared.

 

Also, be careful what signal levels you're looking at.  From the client (STA) you're seeing the AP transmit power.  From the AP you're likely seeing the client transmit power.  In most cases the signal from the AP will be stronger than the signal from the STA.  This is why cranking up the AP transmit power generally does more harm than good because it is often the return signal from the STA that is liming.

@JSchnee21, must be the cosmic consciousness field. :-)
