@TP-Link Thanks : can you give a timescale on the 1.6 firmware ? If within a month, I'll wait for it , if not I'm planning to send the decos back to Amazon within the return window.

@TP-Link Hi, in case it serves a purpose I'll play but the history on this thread suggests this is a problem with the firmware. 1. H112-370 2. No, but i will describe it : router going in to switch...

@Alexandre. thanks for responding - yes. Each time this happens I have to disconnect the decos from the network for the router to return to the 192.168.8.x range - otherwise it goes onto 192.168.9.x...

@GPGeek totally agree with all the posters here : I've had problems with M5 deco's several times in the last few weeks, each time them causing DHCP problems in AP mode and kicking my (Huawei) router...
