I have been using the Deco M5 system for a few days. It is the 5th day now and all of a sudden I have some devices that are not Obtaining IP addrresses automatically. One in particular is an HP laptop with Windows 10. It was working wired and wireless for the past 4 days but today it started struggling. I was able to temporarily get Wired connection to work by changing security setting in Windows 10 from AES to TKIP. However, when reconnecting later on it jumped back to AES and I no longer see the option to change it again. Wireless doesn't even have any options for me to change. 

I also have an iPad mini that failed to obtain an IP address. I did get that online by rebooting the main router. I hope I do not need to do this every single day. 

I also want to stay in Router mode as the main unit is connected to ONT. Something is definitely off with DHCP server. Can I even change the range from 192.168.68.100 - 250... I would mess with it but today me and my wife are both working from home and this all needs to work without heacahces. QOS is also set to standard. One thing that I can only guess is that I'm using the Same SSID/network name as previous router - however, I did release DHCP prior to installing this. An option I don't even see on this Deco..

I really want to like this product. Can someone assist me? I'll try to do another reboot today when I have a moment. Thanks
