Network speed stuck at 100 Mbps insted of 1Gbps

    • Network speed stuck at 100 Mbps insted of 1Gbps

      Hello, recently i get my OMV server working on a RockPro64, which is a singleboard computer. After I set it up i have found out that the network connection between computer and nas goes only to 100 Mbps and nothing higher, so I i went to OMV shell and found out that eth0 runs only on 100 Mbps and not on full gigabit, which should be supported as the board has one gigabit lan port. So far i don't know how to resolve this, spend so far hours on google looking for solution and nothing that helped.
      Version of OMV is 4.4.132-1075 Arrakis (I have tried sudo update and upgrade and they run without error just dont change version)
      Cables tested
      I have tried ethtool command withous succes, when selecting 1000 for speed with duplex full, is gives me link down and nothing more, with 100 for speed it goes link down and right after it link up. When i tried it for first time it went up for gigabit for a second but then shut down link immidiatly.

      If enyone have some solution to this I would be glad, I would try to avoyd reinstall if possible, but if someone sais it is only option i go for it.

      Thank you for consideration.

      I have tried one cable which certainly works for faster connection (tested on internet speed) and that one also only works at 100 mbps for OMV. Thats why its weird and why i am pretty cornered.
      What kind of switch is it plugged in to? I have a rockpro64 and haven't had these issues.

      Please don't PM for support... Too many PMs!
    • It is plugged into dlink router 1750 ac, which has four gigabite ports, two which are occupied, one is to pc, one is a forward from isp (between this router and isp is a gigabit switch and firewall) but those should not have effect on the transfer between pc and nas as only router is in between. Weird is that when i first tested the OMV with is it worked great with ssd and everything and now when is just set it up on home network it is throttled.

    • Plug in some other computer using the exact same cable and switch port and see what speeds you get.

      Alternatively, locate a computer in your network that is connected with GbE and actually working in GbE mode. Then use that exact cable and switch port with your NAS and see what happens.

      I am not sure if i get it right, so i should use other computer on network and try to use it to access the OMV NAS (in that there might be slight issue other computer just cannot see the NAS, network sharing is enabled in windows), if thats the case than this isn't the issue, as my desktop works in GbE mode even tested with pci-e lan card. I will probably try to upgrade the software kernel in worst case, and see if that works.

      No.

      Adoby is trying to find out what is wrong.

      At the moment you have this configuration:

      desktop PC <--------------> Switch (working at 1GbE)
      Rockpro <--------------> Switch (working at 100Mbps)

      So please unplug your desktop PC and plug in your Rockpro into that exact same cable. Check again if it just works at 100Mbps or at 1GbE.
