Slow upload speed on ZyWALL 310
Options
I have an issue with a slow upload speed on a ZyWALL 310. I have gigabit fiber and when testing the speed I get over 900 mbps download, but only about 100 mbps upload. When connected directly with my PC to the FIOS modem, the upload speed is over 900 mbps.The firmware on the router is 4.31. Does anybody have an idea how to improve that?
Thank you

Try disabling BWM.
Maybe a cable between PC to ZyWALL 310 or ZyWALL 310 to FIOS modem is bad.

Do you enable any UTM feature?
The firmware version your are using is quite old, you may check with firmware v4.38.0 -
No UTM is being implemented. I will find a suitable time to update the firmware and retest.Thnk you for taking the time to look at this.0

Just upgraded the firmware, same upload speed as before, no change.

Maybe see if its the given MAC your PC has thats getting a higher speed by using clone by host option in the ZyWALL 310 on the WAN port.0
