Slow Internet speeds

woter324

There are several posts on this subject (all locked for further commenting), so I thought I'd share a possible solution:

I have FTTP broadband at 100mbps and have been plagued with download/upload speeds of ~9mbps over the last 2-3 months. 

Due to the Sophos XG not supporting a popular Intel NIC driver (I219-LM), I run my XG on VMWare's ESXi 7.0 Hypervisor. After spending many hours looking at reports and settings on the XG with nothing show excessive bandwidth consumption, I turned my attention to ESX. The WAN link was showing a link speed of 10Mbps!

After rebooting the hypervisor the link returned to 1000mbps and my download speeds returned to the expected 100 up / 20 down.

I am not sure what caused the link to downgrade, but in my troubleshooting steps, I also did the following:

  • Whilst the XG was down, I applied the latest ESXi patches.
  • Researched the MTU value from my ISP and made sure the XG's WAN connection and the vSwitch values matched.

I hope someone may find this of use.

    Hi,

    the XG is a commercial product meant for business not for home use and the i219 series NICs are low performance devices meant for home or low network performance devices.

    A thank you would have sufficed!

    I am fully aware of Sopho's stance on this subject.

    It's strange how Super Micro choose that IC on so many of their boards, even ones with Xeon processors.

    I'm just grateful VMWare don't have the same attitude.

    I think you are confusing Supermicro PC MBs which use a range of intel and realtek chips with the server MB which use i210 and i350 series chips for the main processing and other chips of for the support services on the motherboard.
