I assume you mean 150 Mb (bits not Bytes)
Have a look at the Ubiquiti UDR
https://uk.store.ui.com/uk/en/pro/category/all-unifi... The equipment is top end consumer and also professional/business. Not necessariky the cheapest, but good quality build, reliable.
It runs the Unifi Netwrok software - the same as the UDM-Pro and UDM-SE so should have the same capabilities.
On a UDM-Pro, you can set DNS for both IPv4 & v6
Create two or more WiFi networks - so you can have one for the kids which a scheduler running.
My experience is with the -Pro & -SE with WAPs so no knowledge of the coverage but in a large house, I have just two UI WAPs and can get 300Mbps (minimum) everywhere and why better in some locations.
With current poor coverage though, you may/maynot see an improvement, but with the UDR, you can run an extra WAP directly from it - chose a UI one, and they are PoE powered, so just a single unobtrusive cable.
I have the TBB BQM running on both IPv4 & v6 which nevewr shows an issue. The UDM runs its own speedtest and with a 500Mb service, I see 495-496 time after time after time.
REGISTER in the forum
