@Joseph-TP already did what u said. Previously 1.2.4 if i turn off and on the switch i am able to connect. Iot side is also more stable and able to connect.

@Alain13860 Same. Their software always breaking things. My iot network used to worked well but now cannot connect to even tuya. Last time still able to connect for a while.

@Joseph-TP Yes. Still the same problem. It is ont modem to be800 main router ethernet to be800 mesh router. The firmware becomes worse and worse.

@Joseph-TP They have kicked me out of the grp chat. And their reply take ages.

@Eric-Lung Its a very close speed. Need tplink to fix on their end. Usually speed will reduce alittle due to hardware capability of ur router. And the cables also might affect the quality. Whereas...

The tplink support in wechat have tried to test and all but cant find the solution even though they can spot the problem. Great Packet data loss
