We recently purchased 25 5.7 SMs with hardware version 9.0 and Firmware 6.0. and upgrade the firmware to the lastest 7.0. We have all of our APs running 7.0 and software scheduling and we have 2 Advantage AP that are also running software scheduling for the mean time. Now that you have an idea of our network. The problem that we are having is that these new SMs are giving me miss reading for the RSSI. For example, once the SM links up the AP, the RSSI indicated on the SM states 350 and a jitter of 3-4. But if you go to the Session under the AP it states a RSSI of 850 with a jitter of 3-4.
Can you please assist me with this problem.
Thanks,
Albert
new 5.7 SM’s report RSSI differently. We have also seen this issue on our SM’s, but we’re still able to get good signal around 350-380 RSSI.
at this point, we rarely use RSSI as the signal quality indicator, and rather rely on dBm power levels and link tests.
BTW, the new 2.4GHz SM’s behave the same way.
I was told by Canopy Tech support that the RSSI shown in the Session page of the AP’s is the strength of signal the AP sees from the SM. So, it is possible to have good signal one way and poor the other way (I have seen it may times).
Not too sure about the difference in how the new SM’s show RSSI as opposed to the older ones.

You are looking at the RSSI from two different viewpoints, the AP’s and the SM’s. Also, keep in mind that the RSSI values are unique to each unit and that you should look at power levels in dBm to determing the strength.

Our 5.2 SMs in AES trim are the same way. Like everyone else says, time to
ignore the RSSI values and use the dBm levels.

Thanks to everyone that replied! All of your information helped out.

On all our legacy 5.7 Non-Advantage SM's and AP's, it is usually the case that the AP's Session Pages show better RF Stats (RSSI, Jitter, and Power Level) than the Subscriber Module reports. Which is more accurate?
