Deco S7 hardware V1 software downgraded from 1.4.5 to 1.4.1. South Africa. 
All WiFi backhaul but problem persists with only one device connected. Devices connected in router mode with 2 meshes. 
 

DHCP pool not working. Devices can't connect-apple, Hisense tv, iot cameras, etc. keep having to reboot network. Only Sonos seems to get an IP. 
 

Beam forming on. Problem persist with 5g&2.4g, 5g, 2.4g (either or). 
 

Guest network is not on. 
 

Have just bought the devices and am extremely disappointed by this. Upgraded the firmware and then shortly downgraded it again as per the forums-no dice. 
 

have to continually reboot the system and hope more devices manage to get an IP from the DHCP server. 
 

Apple iPhone 15 pro can't get a dhcp, settings on static and reserved on deco, and the other way -pure automatic DHCP. Can see the iPhone gets stuck in the 169. range indefinitely-same on an iPhone 13 Pro Max. 
 

Have never been able to connect more than 7 IPs of all devices.
 
If not resolvable will be returning units in the next week for a complete refund. They simply do not work. Pointless to have WiFi coverage and no availability for an IP to actually use the internet.
