Netgear SRX5308 Slow download speed

[GIGA_LANMAN]

Hello.

Just updated from copper to fiber line and the SRX5308 wont go over 85mbps, this is going from the ONT socket to the firewall using cat6 cables.

If going from the ONT socket to the included modem/router it works fine.

Did the standard factory reset, changing multiple settings, connection speed/type, also has the recent firmware installed.

Had this firewall for 4 years now and I understand practically every feature so have I missed something here?

Lots of threads online regarding the same issue but either old threads and the firmware update fixed it or there is no answer.

What speed do you get with the computer connected directly to the modem (sans SRX5308)?
That is, are you sure the bottleneck's the Netgear and not simply a reduced line speed? Can you test the unit at a friend's to see if the speed's better in another network?

Until/unless some of the Netgear folks chime in with a more educated answer, I think you're gonna need to do some basic troubleshooting to check/eliminate other possibilities..
