Thanks! Just to confirm, are you using HUB 4000 as well? 

May I know which model you purchased for the TP-Link wireless extender? I think this might help resolve my issue as below.

Has anyone else experienced this issue? I’ve tried only using the 2.4Ghz by disabling both 5.0 and 6.0Ghz in the modem settings but no luck. Any help will be greatly appreciated.The modal number of Lenovo smart plugs I purchased is ZA7F0000WW.
