Fortigate 40F Slow Upload Speeds

[Technician-109]

Hi All:

Hoping someone can help.  My internet service is 300 Down / 40 Up.  Not sure why, but I am only getting 20 up behind the Fortigate.  Here is what I observed / tried so far.

1. Getting 40 at the Modem in front of the Fortigate
2. Tried a switch between the Modem and the Fortigate
3. Tried hardcoding the Fortigate to 1000Full on the Wan Interface
4. No security policies are running, straight up firewall NAT only

Any other ideas?  I saw the article below; it may apply but seems weird to have to put a traffic shaper on my WAN interface.  How would I configure for WAN Interface 1?

Any other ideas outside of what I tried and the article?

Thanks!

Hi,
Try directly from the FortiGate to run some tests from the link in regards to the upload in order to see if indeed there is an issue on it when you run directly from it, https://community.fortinet.com/t5/FortiGate/Technical-Tip-Use-cases-for-the-diagnose-traffictest-com...
