cat 6a 30 foot long cable going to the 2.5gb jack of Ubiquiti UDM Pro Se.
ISP Sonic.net 10gb. Always get at least 3gb up and down at my intel 10gb nics in other pcs
if connected to the 2.5gb jack on the UDM i get under 300Mpb
if switch the cable to a a 1gb jack on the UDM, I get close to 1gb
UDM 2.5 port set to auto negotiate. Forcing it to 2.5 didn’t help.
cabled to a Ubiquiti UDM Pro Se firewall, 2.5 gb autonegotiate rj45 port, max i get is 125 mbpss up and down out to internet.
if I connect to one of 1gb rj45 ports on the UDM, I get close to 1gb both directions.
(if i connect to a 10gb switch that is connected to the UDM 10gb jack, I don’t think I get any connection, but for sure <1gb.)
