I have searched and cant find a solution...help please

[hrpuffnstuff]

I have 2 x echo dot, both connected via TP-LINK mesh, using TPLINK wifi (made a new connection as told too)
The main server went down for 3 days (yes 3 days), and when i reconnected the dots i had to start all over as although the devices/routines was still in place they didnt work
OK, took me a long time, and now heres the problem

Ask alexa to say "Alexa open global player and play smooth"
alexa takes 34 seconds to reply, then another 25 seconds to connect
then Im lucky if she connects the first time.
same as all devices, takes approx 34 secs for alexa to say "OK" when asked to on the hallway lights"
likewise when i ask to turn off

Ive de-registered
Ive unplugged for 10 secs and plugged her back in
Ive re-set TP-LINK (3 times)
Reset the router

All to no avail....still the problem persist

Signal strength on test my speed is 110MBPS

Switched my wifi to TP-Link 3 Deco mesh system and discovered random connection switching of my devices  to different Deco in the 1 story home. This may contribute to the behavior you observe. I took the path of assigning devices that are stationary to the respective Deco device and disabled the automatic optimization for those.
