Hi, Do you have Asus Router or any more or less newish router? , my 2 cents here:
I have the same annoying problem. I think it is miscommunication between Qolsys Panel 2 Plus and Asus Router ( I tried Rt-AC86U, Ag-ax11100 and Rt-Ax88u, the last one was with both Asus and Merlin firmware). I also briefly tried New Netgear 200 router and I cannot recommend it even to my enemy ( BTW same problem with Qolsys)
I have even more wifi problems are with additional Qolsys panels, I created wifi on my main Qolsys 2 Panel plus and connected them to that. I also connected my main Qolsys panel to quest wifi with no access to intranet, since it do not support Protected Management Frames and can be easily cloned.
I found that Qolsys cannot 100% support asus Protected Management Frames even it is not on required, but on capable.
Qolsys should fix their wifi protocol, I do not want to switch off “Protected Management Frames” protocol since it is easy to hack my network.
I have 68 wifi device in my place and only Qolsys have problems with constant wifi reconnection.
I would like to conclude with phrase: shame on Qolsys! (no smily face here) . I want to use much more stronger expression, but I suppose the forum doesn’t allow
