Loss of network after firmware update 1.5.0
Problem arising after recent firmware update. 1.5.0 Build 20240329 Rel. 61026.
I have TP-Link Deco S7 AC1900 pack of three S7(1.0). Almost every morning (midnight to 4am) the Main unit loses internet connection and devices cannot connect to the Main unit even though the WiFi name is visible (I use an iPad for testing).
My usual set up is: Virgin Media Super Hub 3 in modem mode with 250 Mbps BB. I get between 250 Mbps and 290 Mbps on my phone using speedtest app. Usual Operation Mode WiFi Router, fast Roaming disabled and Beamforming enabled. LED Control set to off but now switched on ready for next time.
I have also tried using the Deco as an Access Point but it is just the same. I have just set the Deco and the Superhub as two separate networks so I don’t lose the WiFI overnight (the Superhub is used as the main network and the Deco WiFi is just for testing and for my Sky stream TV box).
I have factory reset all three Decos and swapped the Main unit for what was a satellite unit and which is now the Main unit. Still fails overnight.
Deco S7s are as they came out the box, except for the settings to get them connected. Nothing else on the Network except the usual clients.
I see older versions of firmware are available for download but the release notes for the latest says no going back?
So current setup is VM Super Hub 3 in wireless router mode and Deco S7 in wireless router mode with different network names. Most devices (30+) connected to the Hub 3 and the Sky Stream box connected wirelessly to the Deco (the Sky Stream is the reason I bought the Deco in the first place). That worked fine overnight so I plan to keep it like that for a week or so and then try some changes from a stable starting point.
I don’t want to do the firmware downgrade but it’s good to know I can. If I do would I need to do all three Decos or just the one that’s connected to the Hub 3?
Thanks for the info
