Hi The MTU is 1500 on PC and the 3 qnap, for me it's ok Here is the result of NAS540 (1) : The second NAS540 (2) And here the result of the qnap : It's a big difference, for the same network, câble, and hdd in all NAS... For the test I use physically the same port in the switch, and the same cable physically... The 2…

@RadaSed, I see you accepted the answer, thanks you, but do you find the cause of the default ? Is there a defect cable ? a port on the switch ? a restriction on your routeur ? In case, is your default resolved ? We are here to continue the help :-) Best Regards and nice day :-)

Hi Mijzelf, Result of your command (no problem for me to use terminal). The command is sending in same time a make a LAN speed test transfert : I see the number of rescheduling interrupt increases if a resend the command several times. The raid exist from 2014-2015, when the FW was 5.04, if it's important to know :-) Today…

@ljnrsi, Thanks for this link, very useful for all :-) Perfekt :smiley: EDIT : Additionnal info, the doc (KB) said change type from raid5 to raid6 is possible, but on mine, not possible to manage de volume. Only create (if you have unused hdd or delete the existant volume). But no problem for me, my raid5 is ok and exist…

@NoNameSelected, Hi, You have to know that RAID5 require minimum 3 disk ! You have to install minimum 3 disks, create your volume, transfert your data and after you can add a last disk and extend the volume with the 4 disk the NAS542 accept. Other Solution is to create a raid1 with two disk, transfert your data, add the…

@RadaSed, Are you solved your default ? Do you want more help ? Best Regards

Hi, iperf3 won't work, I think security rules in my computer, I have to check but this week-end... Here result of a top command on my NAS540, anything wrong or anything to explain the slow transfert rate with this ? - I precise Transmission is started, but no download/upload at this time - I have web server for private use…

You have a simple ping test on the GUI of your NAS (exemple in my screen, sorry it's in french) With this you can know if your nas have basic access to Internet, you can ping google if you want :-)

Hello, thanks for all your reply :-) I according the Qnap is more powerful and have 8GB ram... I accept difference, but like Mijzelf said, the 540 is surprisly slow for me too... It's a good idea to test with the Mijzelf recommandation (top and iperf), thanks for your idea, I make this control tonight or tomorrow and post…

@Zyxel_Support ?

If you do not have a tablet or a smartphone, you can install a virtual machine (vmware, virtualbox) and install Android. With this you can after install apply to manage your multy x device with your PC :-)

You can access GUI from external web, and turn it off from your smartphone with this way, but it' secureless than ssh... Mijzelf solution is the best :-)

Normally YES, your data are safe ! This action make only a default reset of the NAS configuration. After you reactivate the folder, the right and the user acces and it's ok Same action here in this post…

@Exflame Hi, do you use the default SSL-Certificat or do you modify it before installing ? My solution (radical) is to uninstall the certificat from your computer and reset the configuration of your nas (2bip) with the button on the rear. After you can re-configure and access to your NAS normally
