Hey I've owned 3 deco units since almost one year, it was fine till i upgraded my internet to 700mbps and 70 up now deco does not work probably to support the speed in AP mode, i don't want to use router mode as it causes double NAT, i tried to format all the nodes with no hope, in AP mode its only able to push around 300-400 mbps even on cable?How its possible for such a expensive router to fail to do such a basic work as Ethernet switch?Thats unacceptable honestly, you can buy 20$ switch and it will able to puch 1 gbps but a 300$ powerful router cant do it?Even with the internal speed test its the same thing.

other issue,, wifi is only able to deliver around 300-350 even sitting on the top of the main node, i tried to disable 2,4ghz and it did not help.
