Poor Internet Speed
I bought the Deco M4 (3-pack) to try and sort out the poor wi-fi coverage in our house, due to the concrete construction I was using the modem/router downstairs for the wi-fi and a ethernet wired access point upstairs. So the problem I have after connectiong all the Deco's up is my internet speed has fallen drastically. Before installed the Deco's I checked my wi-fi speeds, standing next to the FRITZ!Box 7490 modem/router I got 104Mbps down and 52Mbps up on my mobile, I got similar results on my PC which has a wired connection. So I first disconnected the access point and set my FRITZ!Box to bridge mode and turned off the wi-fi, I was then able sucessfully install all 3 Deco's but my wi-fi and PC internet speed was now 20Mbps down and 50Mbps up, rebooting the modem and Deco units made no difference so next I changed my router back and the Deco's to access point mode, I had similar speed results again on my mobile and PC, spent quite a bit of time reading FAQ's and looking for answers but have to admit I cannot work this out, any help or insight would be most welcome.
