Hi everyone - I have 3 Deco M4 units working in AP mode. The main unit is connected to my broadband router via ethernet cable and I still have Wireless signal on the broadband router enabled. Broadband is with Sky, and want to leave wireless enabled for Sky Q mini's

Recently I've noticed poor Wifi performance on a variety of devices. I've gone through the usual rebooting and ensuring firmware was up to date. 

When I look at my Deco app, I see very few devices connected, and see the majority connected to the broadband router. Ths is the case even when I'm right next to a Deco unit and disable/re-enable Wifi to try and force connection to Deco. 

If I connect with an ethernet cable to a Deco unit, I get expected speeds, but if I do manage to connect via Wifi to the same unit (and sitting next to it), speed dramatically falls off. 

My next step in testing is to turn off all Deco units, but can't leave it like that as have blackspots in the house

Curious if anyone has had issues with devices connecting to the broadband router when Deco is a much nearer device. 

Thanks
