[H] Network Problem with Linux/Unraid Server

[Steve Tomporowski]

Hopefully someone is familiar with Unraid and/or Linux for this one.

I have an Unraid server (6.7.2) running on a network with a Netgear
Nighthawk router and recently added a 8TB usb drive to the USB3 port on the
Netgear.  No problems there.  However, when the Unraid server is on (I
don't keep it on all the time), the Netgear will eventually (takes time)
lose its internet connector.  A reboot of the router will restore the
internet.  Now if the 8TB drive is off, then no problem with the Unraid
server on.  The important point here is that I added the 8TB drive to
Unraid as an unassigned device and somehow I can't remove it.  It will be
removed in the interface, but upgrading from 6.5.0 to 6.7.2 made it come
back, probably meaning it was still there.
I will post this on the Limetech Community, but just wondering if someone
has some idea as to what I've done wrong.

It appears you were right about disabling the 2nd NIC because the 
networking is now working as it should. How would I install VMWare 
Player to use the currently unused NIC. If I install VMWare player it 
will automatically set up a virtual share on the existing NICK. thanks Iopaka

and the other is "Link layer topology discovery mapper I/O driver"

nothing else should be checked or it will interfere with the primary NIC
settings. VMWare should be set similar

If both nics have IPV4 or IPV6 boxes checked I can almost guarantee it will
cause problems like you describe. Only the primary NIC should have those
checked

Cut the stack to bare minimum killing QOS and Ipv6 along with any other
extraneous items.

Be suspect of any feature on 10's stack not on 7's. Always suspect newer
Microsoft enhancements like homegroups.

I use my extra NICs for virtual box. The network cards that are only being
used for virtual machines should only have 2 things checked off in the
properties

the virtual bridged networking adapter (for virtualbox its "VirtualBox
NDIS6  bridged networking driver")

and the other is "Link layer topology discovery mapper I/O driver"

Re: [H] Network problem

[Joe User]

I'd reseat the cable. I'd swap out or if its an on-board NIC, put a real 
NIC in. Also you can cut the end and re-tip the cable, I've run into 
that more & more.

That was one of the first thing I checked to make sure the computer 
could not put the NIC to sleep



 Does it have a wireless nic or onboard chip that is not disabled.


It has two NICS. ASUS P9X79 I haven't disabled one but I will try 
that. My goal was to use the second NIC for just for VMware. But I 
haven't figured out how to do that yet.


 When the computer won't connect to other devices what does it say 
if you open a CMD prompt and type ipconfig.


right now the computer will connect to other computers but not the 
printer. BUT other computers can not connect to it.

Does the network address show up properly?  yes



Can you ping other devices?


 On the other computers I get a I get a Windows cannot access.. 
check the spelling otherwise there may be a problem with your 
network. BUT yes I can ping the workstation from other computers that 
can not connect.



  Does the router show the device connected properly in the "Device List"?


I don't see the router at all under Device list... but it seems 
unlikely to be the router because all the other computers are working 
and I don't see it with my laptop either. I had to print today from 
the laptop because I can not print from the workstation to the network laser.


Once I loose complete connectivity to the LAN I will go through the list again.

thanks for the help!

Re: [H] Network problem

[lopaka polena]

Few things to check. Does this computer have power settings that let it go
to sleep or power off peripherals? Does it have a wireless nic or onboard
chip that is not disabled. When the computer won't connect to other devices
what does it say if you open a CMD prompt and type ipconfig. Does the
network address show up properly? Can you ping other devices?  Does the
router show the device connected properly in the "Device List"?

I have virtual machines that do this sometimes and usually have to disable
then re-enable the network interface to fix things. I've occasionally had
to do this on windows 10 machines but usually only the boxes that have
multiple NICs

[H] Network problem

[Winterlight]

I have a personal home workgroup comprising of my primary Windows 10 
PRO workstation, some LIVA mini computers I use with TVs and  some 
laptops and wireless phones. Wireless is handled by a UniFi 
AP-AC-Pro. I have single router plugged into a CABLE modem and into 
Netgear gigabit switch. I have a couple of network printers and a 
HDHomerun TV turner running on the network. This is a new house with 
a recent ... within the last three months ... setup. My primary 
workstation is a new clean install of Windows 10 PRO.  The network 
works great EXCEPT for my primary workstation. It was working just 
fine and I do have a Acronis image file from that time = a month ago 
which I may be forced to restore but I would like to find a lasting 
fix for this.


My workstation keeps losing network conductivity. One hour I think I 
have fixed the problem but 18 hours later I can't connect to other 
members of the LAN or the printer won't work, or lan members can't 
connect to the workstation but the workstation can connect to them. 
The workstation always has internet and that tells me that the 
hardware is working although I have swapped out and checked the 
switches. I have checked every setting on the NIC. I ran windows 
troubleshooter and it came up with a problem with the virtual 
network. I thought I found it so I completely removed VMware player. 
And it worked again ...but for a matter of hours. Then I just removed 
the NICs with their drivers, rebooted it reinstalled and everything 
worked but 17 hours later I can not print to the network printer, and 
while I can access other members of the LAN they can't connect to me.


Any ideas? Is there software that can diagnose this? Should I just 
give up and restore my working backup? Thanks!
