I was told 30Mbps but I routinely get double that. I have seen some big numbers, but never 1Gbps. Keep us posted. :-) Re: QoS and VLAN settings on High-Speed Internet Gateway Can’t answer your question, but would it be reasonable to put an inexpensive (aka used) router running DD-WRT (https://dd-wrt.com/) after the 5G21 and your lan(s)?
