February 25, 20251 yr Hello, currently still on my unraid trial (4th week) and since approx. a week I´m facing low speeds on my unraid server. It doesn´t matter whether I´m downloading from the internet (I have a 1 Gbps home connection) or downloading locally, I´m only getting around 100 Mbps instead of the 1 Gbps, which I was getting initially. This "limit" of 100 Mbps is quite consistent. I have no clue what could be causing this and how to approach diagnosing and troubleshooting. Would appreach every hint. Setup: 2x 18 TB HDDs Seagate Exos X18 (1 parity) 1x 250 GB NVMe SSD as cache ASRock N100DC-ITX mainboard with integrated CPU The board has 1 Gbps networking and is connected directly to the router, which also suppots 1 Gbps. Also haven´t touched this. Edited February 25, 20251 yr by sl1ck

This can be caused by one of the twisted pairs in a LAN cable not making end-to-end contact and then a 1Gbps will silently downgrade to 100Mbps. It can be the cable, LAN port at either end or cable not properly pushed. The diagnostics should allow us to confirm if this is what is happening.
February 25, 20251 yr Author Thanks for looking into this issue, Ive attached the diagnostics file to this post. homeserver-diagnostics-20250225-1021.zip
February 25, 20251 yr Community Expert Speed: 100Mb/s NIC Is only linking at 100Mbits, try a different cable, switch port, or NIC.
February 25, 20251 yr Author Played around with the cable and it is back to 1 Gbps. Excuse the amateur question - the speed dropped mid download, I didnt think this could be a hardware issue.
