I have three units of the Deco S7, on the label I can see the version is shown as v1.20 but the strange thing is that on the firmware upgrade page, it shows them as S7(1.0) model. Also, the units are using the firmware version 1.5.0 Build 20240329 and after this upgrade was done, I started to face some random disconnects, connection slowness and so on. Already tried using as Router Mode and Access Point mode, so I was wondering, is there a way to downgrade the firmware? I tried upgrading with the ones I could find on the Download Centre but it says " Upgrade failed. Please select the latest version of firmware to upgrade."
