I've been using 4 TP Link Deco E4 for my mesh wifi network for more than 2 years and never had much issues but since a little bit less than a week the network is totally unstable, with bandwidth drops or worst, total lost of connexion from my device to the Deco E4.

What's happening:

I'm using my device and suddenly I lose the connexion. If I check the settings, I'm still connected to the device but there is no network connexion available. After a couple of minutes, switching on and off the wifi connexion of my device, it's back to normal. When I try to access my network setting while this issue happens, the Deco app only says "We couldn't find Deco", even if my devices says that I'm connected to the network.The more the time goes by and the more frequent this issue seems to happen.

I know for a fact that the issue doesn't come from my internet provider (Starlink) as I've been closely monitoring my wired connexion and that there is no stability issues there.

Here's what I tested so far:

• All E4 devices are up to date
• Rebooting doesn't change anything
• Issues happen with all types of wireless devices (phone, tablets, laptops, etc...)
• Using the network optimization feature on the app doesn't solve the issue
