Model: Deco S4  
Hardware Version: V1
Firmware Version: 1.5.0 Build 20210607 Rel. 56436

Hey there so recently sometimes my speeds will drop from normal 200mbs+ but sometimes it randomly drops to 100mbs, usually I reboot the decos, and it goes back to normal. But today for some reason when I rebooted it today to fix it, the speed still stayed the same any answers on that one?

Hi, thank you very much for getting back to me.

I see there are 3 Deco S4 under your TP-Link ID and did all of them have the unstable speed issue, or just one unit?

Have you ever checked whether both Ethernet and wireless speed all dropped below 100m/s?

If possible, please install the firmware on this link which optimized the CPU performance of S4:

thank you and wait for your reply.

Thank you very much for getting back to me.

It is planned to add a reboot schedule for Deco on 1.6.x.

Maybe you could wait for a while for the new feature.

Or some users shared their experience about setting up a reboot schedule via smart plugs, which is also a good idea.

It is on the Black Friday sales recently, and maybe you are interested in getting one of the smart plugs to have a try.
