Connect to DSM kills internet

[dochammoc]

Hello.  It seems my internet (and LAN connection?) on PC that I connect to DSM with dies shortly after connecting to DSM.  Other devices on network seem okay.  

 

I have a Netgear Nighthawk R7800 X4S AC2600 DD-WRT FlashRouter.

I installed DS3615xs 6.1, Jun's Mod 1.02b and extra 3615 - v4.8

 

I have server set to static IP.

 

I also got Active Backup for Business working on DSM and 54 bit client installed on Win10 PC having issue.

No offence to you but it’s a little bit hard to understand what you exactly mean.

 

You mean that your PC lost it‘s internet connection after you logged in to DSM with a browser? Never heard of this before. 

 

Is a DHCP server enabled on your Xpenology and maybe misconfigured? But if that’s the case you wouldn’t have any internet connection at all. 

 

Maybe you should try another browser or empty your browser‘s cache. Try to open a cmd shell before you connect to DSM and let it ping constantly another server, like:

 

ping -t google.com

 

See if anything changes after you logged in to DSM.

Let me try to be more clear.

 

There is something on my xpenology server that is causing internet to die on my PC.  I know this because I can power down the server and all seems fine.  Sometime shortly after loging on to the DSM via Chrome on Win10 I lose internet connection on the PC. It's fairly consistent.  I'm not sure if it is related to Active Backup for Business which I have installed on DSM and client on my PC so that it gets backed up.  Seems a likely place to start.  

 

Internet does eventually return.  Perhaps when the backup is over?  Need to do some more testing.

 

I have four packages installed:

- Active Backup For Business

- File Station

- Universal Search

- Hyper Backup

 

The first three want to be updated.  The last I stopped as I'm not using it.

 

Some data from Info Center:

Model name: DS3615xs

DSM version: DSM 6.1.7-15284

 

I have auto updates off .. and will NOT update unless via instructions on this forum.

 

I tried Active Back of PC while continuously ping google.com.  Only took 5 minutes this time as prior took nearly three hours.  But it completed without killing internet tonight!  Last night as well as other nights I can't stay connected more than a few minutes.  Rebooting is only way to recover (internet troubleshooter, etc does not work) but logging back on only repeats with internet dying again.

 

So for now I'm holding my breath but I doubt this problem is gone.  

 

P.S.  It is an almost clean install of Win10 also.  I do have Webroot Secure Anywhere running and Malwarebytes trial.  The later I'm removing.  Who knows, can't rule out something foobar with the PC (yet).

I think that only a connection to DSM is unlikely the reason for any connection drops. ActiveBackup will cause heavy load on your PC's NICs when running and - AFAIK - on your system at all (think it works with VSS). Usually you don't work on a PC/client when a backup is done, regardless of the software.

[dochammoc]

ok.  so still happening.  Internet is down.  Reboot is only thing that fixes.  Within a minute or so after reboot internet is down again.  I unplugged LAN cable from xpenology server before reboot.  Seems to be working now.

 

If it makes a difference, I also have a plex server (on proxmox).  But it sits idle and does not seem to affect anything.

 

Next I'll plug the server back in and see if problem returns.  The uninstall active backup from client PC.  There must be a logical explanation.

 

Any help is appreciated very much!

Perhaps you've reviewed that, but what MAC address and IP have your devices on LAN:

 

• PC  (MAC/IP):
• Router (MAC/IP):
• Xpenology (MAC/IP):
• other devices....

Could be a conflict with IP/Mac Address...

[jensmander]

Normal Windows PCs yell about IP and computer name conflicts (since 98). Could be a MAC conflict, packet drops from the FW (although most soho routers give a damn about internal traffic in soa mode) or a switch which closes a connected port (broadcast storm, excessive packet traffic, crc errors, ...).

 

I would try a huge SMB transfer from and to the NAS to see if it’s only related to Active Backup.

Thanks jensmander and bluesnow for your input.  I don't give up so eventually will figure this out.  I'm a software developer of nearly 30 years (most recently .NET) so spend a lot of time researching solutions.  But networking and hardware is not my specialty.  I managed to build a Plex server on top of proxmox and an xpenology server, each with a 12 bay enclosure full of two terabyte drives totaling 48 terabytes.  I'm ripping all my movies and backing them up (along with other PC's on network).  Along the way I upgraded to Netgear Nighthawk router which I got from flashrouter.com with DD-WRT pre installed and a VPN with PureVPN.com.  I use Kodi on an Nvidia Shield with a Plex backend using plexkodiconnect plugin.  Finally I own my own cable modem instead of renting from cable company.

 

Let's just say, I've come a long way and it's been a journey.  I'm a Microsoft guy, not linux ... so all the more a challenge.

 

It's not conclusive BUT, I have not had any problems after I uninstalled the Active Backup Client from problem PC.   Before I uninstalled I unplugged network cable from xpenology server .. again no issues.  Or I can leave xpenology server shutdown.  Note that Active Backup continues to run on xpenolgy server, it just skips backup of PC waiting for reconnect.  The plex / proxmox server continues fine as well and is accessible form said PC as well.

 

As suggested I copied a nearly 200 GB folder of nearly 200,000 files to the server from PC and back.  No issues.

 

I have many devices.  I have configured a number of them with static IP's which put outside the routers DHCP range and also reserved the IP.  I read somewhere this isn't needed and MAY cause issues.  I could try removing the reservations (or putting them in DHCP range).  

 

My router: 192.168.11.1 /  78:D2:94:BF:15:D5 (LAN),  78:D2:94:BF:15:D6 (WAN), 78:D2:94:BF:15:D7 (Other?)

   DHCP Start to End IPs 192.168.11.100 to 192.168.11.149

 

   Static Leases (I should verify matches actual device  ..  I entered all these after configuring static ip on device)

       printer : 192.168.11.11 / 00:1b:a9:ca:c4:d1

       router:  192.168.11.1 / 78:D2:94:BF:15:D6

       dawn (nvidia shield): 192.168.11.32 / 00:04:4b:4a:a1:0f

       marantz-avr (receiver): 192.168.11.99 / 00:06:78:1F:46:75

       homer-remote (harmony remote): 192.168.11.97 / C8:DB:26:09:27:47

       vidia (Plex VM on proxmox): 192.168.11.152 / A6:FA:10:52:D8:1D

       lilo (xpenology server): 192.168.11.21 / 0C:C4:7A:12:0C:09

      stitch (proxmox server): 192.168.11.31 / 00:25:90:F5:68:D6

      stitch-IPMI: 192.168.11.24 / 00:25:90:F7:00:EE

 

*IPMI is the Intelligent Platform Management Interface which can be used configure server hardware before OS is loaded.

 

In addition I remember setting a static IP on the following:  (I need to look up / verify)

    lilo-IPMI   ??? / ??? .. need to look up

    Areca-lilo (nic for one hard drive enclosure)   192.168.11.23 / ???

    Areca-stitch (nic for other hard drive enclosure)  ??? / ???

 

And then there are all the DHCP (mostly wireless) devices.

- At least half a dozene i-devices  (phones, pads, watches)

- three or four smart tv's

- 2-3 laptops and/or PC's

- two to three rokus

- two amazon firesticks

- a few others I may be missing

 

It might be time to install Active Backup again and see if problem returns.  Maybe there is another PC (bare metal) backup program.  Maybe there is something else I can try ...

 

[dochammoc]

Blah .. Active Backup for Business is definitely the problem.  It seems as soon as a backup starts network goes down.  I can copy large numbers of files over SMB .. so network seems up.  Frustrating, as Active Backup DID work for awhile.  Not sure what changed and I hate to switch backup software.
