Dear Expert
We are using Fortigate D-200 firewall. Recently we have up-graded our internet Bandwidth 50 MB to 100 MB.
But internet speed did not cross 45 MB .Although we have disable traffic shipper feature globally .
We are not understand why internet speed not utilizing up to 100 MB .
If the ISP's gateway/router device has not been power cycled since the speed increase, I would do that first.
On the CLI perform diagnose hardware deviceinfo nic <inteface name>
Output should look similar to this:
# diagnose hardware deviceinfo nic wan1 Description Intel(R) Gigabit Ethernet Network Driver Driver_Name igb Driver_Version 5.0.6 PCI_Vendor 8086 PCI_Device_ID 1533 PCI_Subsystem_Vendor ffff PCI_Revision_ID 0003 PCI_Bus 5 PCI_Slot 0 MAC_Type 6 PCI_Bus_Type PCI-E PCI_Bus_Speed 2.5Gb/s PCI_Bus_Width Width x1 IRQ 16 System_Device_Name wan1 Current_HWaddr 90:6c:ac:3e:cc:xx Permanent_HWaddr 90:6c:ac:3e:dd:cc Link up Speed 1000 Duplex full FlowControl current:0/requested:3 Interrupt mode MSI-X Rx queue(s) 1 Tx queue(s) 1 Rx_Packets 186009705 Tx_Packets 142789065 Rx_Bytes 221319840722 Tx_Bytes 21885484538 Rx_Errors 0 Tx_Errors 0 Rx_Dropped 0 Tx_Dropped 0 Multicast 2130115 Collisions 0 Rx_Length_Errors 0 Rx_Over_Errors 0 Rx_CRC_Errors 0 Rx_Frame_Errors 0 Rx_FIFO_Errors 0 Rx_Missed_Errors 0 Tx_Aborted_Errors 0 Tx_Carrier_Errors 0 Tx_FIFO_Errors 0 Tx_Heartbeat_Errors 0 Tx_Window_Errors 0 Tx_Single_Collision_Frames 0 Tx_Multiple_Collision_Frames 0 Tx_Deferred 0 Rx_Frame_Too_Longs 0 Rx_Frame_Too_Shorts 0 Rx_Align_Errors 0 Rx_Flow_Control_XON 0 Rx_Flow_Control_XOFF 0 Tx_Flow_Control_XON 0 Tx_Flow_Control_XOFF 0 Rx_Control_Unknown_Opcodes 0 PHY_Media_Type 1 max_frame_size 1522 CTRL 00100241 STATUS 00280783 TXCW 00000000 RXCW 00000000 avd/ctrl 0de1/0200 Look at the Link speed and duplex lines and check the various rx/tx error/dropped counts. Going to assume the D200 is connected to the ISP's gateway/router device at either 100 or 1000 full duplex - if you see half duplex then I would say there's a problem. If there are rx/tx error/drops counts, wait while then perform the diag test again to see if the counters increase.
If there are no error check the interface configuration, eg.
config system interface edit "wan1" show
and look for any speed, inbandwidth, and outbandwidth lines.
Further troubleshooting may including direct connecting a laptop to the ISP gateway/router and running speed tests, contacting the ISP to confirm their equipment is properly configured, suspecting a possible network switch issue.
