Hi David, after 1.8.0 upgrade of 5 X50 (all v1.0EU, so i think same hardware inside), the behaviour is somehow strange... Wifi Network performs great, when i restart a Deco, the clients switch to another one in a couple of seconds, so i have noticed a relevant improvement in wifi stability and reliability (also shortened the response time in IoT switches/light command executions). But: - all decos (5 x50 and one x50-outdoor) are wired-connected to the same ethernet, with the x50-5G as main deco/router at the start of tthe wire; - the x50 outdoor and 1 x50 are solid green, other 4 x50 are solid red (after the initial colour sequence and some second of blinking red, as in the past, but previously they turned green after red bllinking) - restarting / power disconnection-reconnection of decos can't change the situation; - using LED control option in deco app (i have the last version) can only turn led off or on, but color does not change; - but the strangest thing is that 2 units of x50, connected to the LAN by the same switch (zyxel xgs1250-12) are both perfectly working after the FW upgrade, but the led are solid red for one and solid green for the other.... (?) I will send to you to support email the system log of these two decos, peraphs your engineers could compare them and find why one is red and other shows green... Cheers! Alex (aka Boezio)

p.s. mail sent to you a second ago... bye!

  @David-TP  hi

1. Clients started disappearing again 1-2 times. . The client is connected, but it's not visible.   After rebooting it was cured.

2. Backhaul issue with x20v4. This access point started losing the link to the main x50. The red light switch on a couple of times.
