Hi everyone, 

Over the last wile I have been having a lot of issues with really high ping across my deco's. Connecting direct to my ISP router the ping is good around 30-40 but every so often when connecting to the deco's it will jump into the mid to high hundreds. It happens across all 4 of them. One of them is using direct Ethernet back haul and even wiring my laptop into it the issue is still there. 

Can anyone suggest any trouble shooting steps? 

Have already updated firmware and tried both access point and router mode with no joy. 

Thanks 

Matt
