Netword Performance issuse

[ylafont]

Need some guidance on a Networking issues that started a few days ago and I am not sure how to how to troubleshoot.

Problem - Every two minutes or so I lose the ability to access the internet, web surf, streaming audio RDP connections, VOIP call are cut off and so on. This last about 20-30 seconds and then connections are restored.  The odd thing here is, the internet connection stays up and does not appear to be the problem I have monitored the router and all is well, I have called Time warner and had the connection tested.  Although I loose RDP connection, I don’t lose my VPN connection.

Troubleshooting- I disconnected EVERY Device from the network and only attached the PC to the router and the PROBLEM disappeared.  I then began to plug in devices one at a time every two hours or so to see what device was the problem.  After all was said and done, I have identified my READYNAS PRO is the cause of the problem.   Each time I unplug it from the network everything returns to normal.

Just in case there was an IP conflict - I have change the IP.

Just in case the RJ45 cable was bad - I have changes the RJ45 cable

Just in case the NAS Ethernet port went bad - I moved to the secondary Ethernet Port on the device

Just in case the Ethernet port was bad on the switch, the NAS connection was moved to another port.

How can I find the cause of this problem?

Are you forwarding ports to the NAS in the router?

[ylafont]

I do have ports being forwarded on the router- however no ports are being forwarded to the NAS itself.

i am curious  the bond0 and  and tun10 interfaces.. are they supposed to be there?

I see both interfaces on my pro (though in my case I use bond0). I am wondering if tun10 is set up for remote.

What add ons do you have installed?

[ylafont]

No add-ons install on the NAS.  

to be on the safe side, I just turned off

Discovorry Services

ReadyDLNA

AFT protcol

FTP Protocol

The only services running are  CIFS, HTTP, HTTPS

[StephenB]

If you have a scratch disk, you could remove the pro disks (labeling them by slot), and install the install disk.

Then see if the clean factory install has the same problem.

[ylafont]

Currently moving data of NAS to performe a reset.     NAss has been one for over three years, no changes have been made. How coudl this have happend and more importantly how can it be prevented?

[StephenB]

Its hard to say w/o knowing the cause.

Did you check for a filling OS partition?

[ylafont]

It took about 10 days for data to copy with wll the network drop offs.   The only wasy to fix this issues for me was to reset to factory default!  Arg!
