Forigate slowing the internet Speed

[Maan_Alhajjam]

Hi community,

I'm connecting a fiber connection to the firewall with speeds between 350 and 450 Mbps, but I'm only getting 10 Mbps in return. I understand that there will be some speed reduction, but is this normal???

I have disabled all security features in the firewall policy and the "threat-weight" configuration, but I am still experiencing the same speed issues.

Here is my configuration. Please, if you have any advice on how to increase my internet speed, I would appreciate it.

Hello Maan, 
Don't you have some traffic shaper applied to your policy ? 

And another point : 

If you have all time about 10 Mbps I suggest you to check any intermediary devices, as switch which can have only 100 / 100 Mbps. 

And please tell me, are you making tests from PC connected by wire or by WiFi ?

Hi Tajfun,

No, I don't have any shaper applied, and the speed is getting from a maximum of 17 Mbps to 8 Mbps.

I'm testing from the SSID I created in the Fortigate, and this is the configuration for it:

It looks like basic configuration. 
It the same problem if someone will try to access internet by wire ? 

And the simplest suggestion

Don't you have an antivirus/firewall on your computer that scans traffic and significantly affects its speed?

Hi Tajfun, 

I apologize for my delayed response.

It's not an issue with the device antivirus or firewall. When I connect directly to the fiber, I get around 400 Mbps. However, when I connect through the firewall that is providing the internet via fiber, I'm experiencing the low speeds issue.

Connect directly to Fortigate (or to distribution switch) with PC by wire to be sure that issue is only related with WiFi - or with whole unit
