We have installed two Nuvo P100 music servers in a clients home.  They are in two different parts of the house (gym, family room), but share the same LAN, app login info, etc.

Our client streams Pandora and SiriusXM off the internet and streams iTunes locally from their Mac through the servers.

Issue is - all three services cut in/out on both servers at all times of day and night - everyday.

When we have gone out to troubleshoot the system works perfectly for us.  No issues at all...

One would think it's do to poor download speed, but they're getting 30Mbps down - Plenty for streaming audio.

What we've done:

Sent Nuvo logs to Nuvo support - No issues to point at there.
Replaced the Gigabit switch
Factory reset and did a TLV flash of both units
Reentered all system login info, etc.
Checked all wiring (cat6 home runs to common switch to router to modem)
T/W modem and Apple Extreme router working fine

We even loaded up the LAN by playing both servers, all AppleTVs, streamed netflix off the laptop, etc. and had no issues - not a burp...

Question: is there a network monitor that we can run in the background so that when he says this issue happened at 7am in the gym we can check the network logs and see if there was an issue/traffic on the LAN that could have brought it down or slowed it down...?

Your suggestions and input is much appreciated.

Check your DNS Servers. The few times we've had issues with streaming devices they were associated with the DNS Server 2 address..

what about dns 2 address?

Thanks.

We use:

8.8.8.8
8.8.4.4

but come to think of it there's another person who maintains their network gear and maybe he changed it.

i thought googles secondary was 8.8.8.4 not 8.8.4.4

No, 8.8.4.4 is correct.

Any issues we had related to not having a DNS 2 address or a "bad" one.

10-4. we always use the router for primary and 8.8.8.8 for secondary.

ihiji has a built in WAN speed test, [Link: ihiji.com]

What is the ISP? We have had issues recently with version Fios and pandora.

1) Always use 8.8.8.8 & 8.8.4.4 for DNS

2) you can use wireshark to see all the data going across the LAN.

2a) if you have a managed switch you can mirror the port the Nuvo is on and then see all data to/from using wireshark

With wire shark you leave a laptop on site and set up remote desktop so you can get into the laptop and read the logs/see whats going on when client calls.

I always try to be redundant when it comes to DNS servers, so I use 8.8.8.8 (Google DNS) primary with 4.2.2.2 (Verizon/L3 Communications) as a secondary entry. Google DNS is generally very reliable, but it has gone down on several occasions in the past.

4.2.2.2 stopped being 'public' a while ago and can lead to DNS problems now.

Unless you are a L3 customer that is.

Watching the net for errors is going to be commonplace as the lack of net neutrality rears up and causes phone calls for us doing IT work.
