My finance and I have an GL-AX1800 that has been working great (we love it, we also have a GL-AR750S for travel) for all client devices except 6 of them. The ones in question randomly get disconnected and do not attempt to reconnect. This happens between 1 and 10 times per day. These devices work fine with our 3 other, older APs (the latest one is being replacing with the GL-AX1800, the rest of disconnected/in storage except for testing) and only exhibit the disconnect with the GL-AX1800. All other client devices work perfectly. When the issue happens, whatever it it, all 6 devices get disconnected within seconds of each other.
So we have 3 wired client devices, ~50 2.4 GHz client devices, and ~10 5 GHz client devices. Out of those only 6 of the 2.4 GHz are having any issues. From that 50 2.4 GHz group we have 21 of them that are TP-Link Kasa smart devices (plugs, strips, lights, outlets, and cameras) and the 6 misbehaving devices are among them (4 outlets, 1 power strip, 1 light). However, the remaining 15 devices do not have any issues including some brand new devices and some much older ones. The firmware on all of the Kasa devices are up-to-date.
Again, when connected to any one of our older APs they work fine (tested for 3 weeks, 2 weeks, and 4 days with all of them.) Does anyone have a suggestion on how to resolve this as whatever the problem is seems to only exist with these 6 devices and the GL-AX1800.
