May 31, 20197 yr Curious if anyone else has experienced this, but over time my unraid instance tends top drop to 1MB/s If I reboot it it jumps back up to 100MB/s for a few days and then drops back to 1MB/s. I have a pro license... it is annoying as h&ll.... any ideas?
May 31, 20197 yr Community Expert When it happens again, and before rebooting, go to Tools - Diagnostics and attach the complete diagnostics zip file to your next post.
March 4, 20206 yr Author Find Attached. It has been almost a year. Same problem has persisted. Every few weeks a restart is needed. System drops to 10Mbit, restart 1GB. bfd-diagnostics-20200303-2257.zip
March 4, 20206 yr Community Expert Nothing obvious in the logs, but from your description I would suspect a LAN cable (or port) is dodgy. A 1Gbps connection requires 4 twisted pairs in the to be functional while 100Mbs ( ~ 10MBps) only requires 2 twisted pairs to be operational. With a dodgy cable/port it is not unknown for the LAN connection to silently degrade from 1Gbps to 100Mbps or lower. Because the LAN keeps working a cable/port issue is often not diagnosed.
March 5, 20206 yr Author The curious thing is the unplugging/re-plugging the network cable doesn't change anything, nor does swapping to another cable. I would expect this to trigger the system to re-detect the available transfer rate. This system did run as my windows desktop for some time on the same network without any network issues. So this does lead me to lean towards the issue being driver related between unraid and the network adapter.
December 29, 20205 yr Sorry for bringing the topic back from the dead but were you able to find out where the problem was in your case? I have the exact same problem, Unraid server downgrading network from 1Gbit to 10mbit once the server has been running about 10-20 days and going back to 1Gbit upon reboot. Have changed cables multiple times (I have a lot of them), even swapping cable/switch port with another system, which runs flawlessly on both the cables and ports - but the Unraid server drops to 10mbit after a while. I am suspecting the network card atm but it does seem like a weird hardware problem - the reboot helps immediately for 10-20 days before the downgrade happens.
