FORTIGATE FG200E CUTS INTERNET FROM 30MB/S TO 3MB/S
Hello Team
I am new to this forum but have a big issue.
We have FG200E running on
Firmware | v7.2.8 build1639 (Mature) |
The ISP provides 30Mbps, and when we test with a laptop connected directly to the ODU, we get over 25Mbps; however, on Wi-Fi and LAN through the FortiGate, we get less than 5Mbps.
There are not many configurations on the firewall, it is only working as a router and 1 site-to-site VPN which is not active.
Kindly guide me on how to solve this.

Hello @nradia_FTNT
Thanks for the KB. After following it, I found nothing wrong with anything but still the Internet is slow. I really don't know what happened.

Hi @wanumet
Can you try running a continuous ping from fortigate and end device to see if there is any packet loss?
Can you also try using a different interface on fortigate if you get same speed there as well?
Also take a pcap on WAN interface and check if there is any retransmission or other errors seen there.
Regards,
Varun

Hello @vbandha
A continuous ping from an end device to the firewall does not break at all. Pinging the Google dns 8.8.8.8 also does not break.
I will configure a new port and check
