HP micro server network speed issue

[Blinkz]

Hey everyone,

I’ve just replaced the SSD on my HP microsever gen 8 and took the opportunity to change from windows server to windows 10, mainly for usability issues I had with a few programs. I only use the server for Plex and newsgroup downloads along with a basic home CCTV. It has a 1 gig NIC.

Since installing windows 10 I’ve been having a strange speed issue with the server. It only seems to be able to download or upload at between 100-200mbit/s. I’ve FTTP so it should be close to 900 both ways. My PC gets that so the fibre conx seems ok.

Using iperf between my PC and server, the server is only sending at 100-200mbit when acting as client. But when my PC is client and sending to server it gets 900 odd. Hence my confusion. I don’t see why the server seems to download on network at full speed but can’t upload at more than 200. But then I don’t understand why the internet speed test says 200mbit for both down and upload.

I’ve tried all the usual, restarted all the network/router, tried new cable etc. nothing changes it.

I’m running a unifi setup with a USG 3P router, a main switch and a POE switch with a cloud key keeping track of it all. It recognises that the server is 1gig.

any suggestions??

Have you downloaded the network driver from the motherboard manufacturers website rather than what Windows decides is best?

Semi-related note for general: if you're running Speedtest.net checks then it's worth downloading the app for somewhat more consistent results rather than running in browser.

Thanks for the reply. I’ve not been able to find any other drivers for the nic, as it’s enterprise they all seem to be for windows server editions. I’ve tried both HP and Broadcom websites to no avail.

Good tip regarding the speed test app, I’ll try that. Although it wouldn’t explain the iperf results. Will see what the app says …

Seems like a driver issue to me, but you might not be able to resolve it. Are you able manually set the network speed in the NIC settings?

Worth considering a separate NiC for the pc (if it will fit)?

Thanks for the reply. I eventually found the driver on the manufacturer website and have installed it but no change. I’ve check the settings and all are set to auto. The router sees it as a gigabit connection, but for some reason it doesn’t reach the full speed in one direction. It worked fine before which is the frustrating thing! Is there any other settings which might affect the connection?
