BluOS / Bluesound Node buffering and lagging
Answered
I have aNighthawk AC2600 R7450 Router. The Node and BluOS connect to the router just fine, but there is significant sluggishness in the BluOS ... really slow response when performing any action that involves searching for, selecting, and playing audio. Also, when I select a track to play or when I switch from a track that is playing to another track there is a consistent 12-second buffer. The Bluesound people have not been able to resolve this for me yet, and I'm hoping someone here can. I have a strong signal (-40 dBm). I've rebooted the router. Uninstalled and reinstalled the app. Rebooted the streamer. Enabled IGMP. Pretty much all the obvious things. Also, I do not have Nighthawk Armor security (the Bluesound tech people suggested I turn that off if I have it). Is there some setting on the router that I can adjust to get this running more seamlessly? I'm pretty ignorant of router technology, so try to keep things simple for me, if you can. Thanks!

End user here…
The slow response in the App does strongly suggest a communication issue, you don’t mention what platform the BluOS controller is running on but do suggest trying another device in case it related to that.
VPN - if any are configured disable them
Subnets or VLANs - move NODE and controller device onto same
Router- check router settings to ensure Multicast traffic is allowed. Also see if there is a setting that says IGMP Snooping or IGM Proxy... turn it on.If you have a spare / old router kicking about then it’s worth testing with that.

Yeah, sorry. I'm using an iPhone, and I have the latest upgrade installed. I don't have an old router, but I was thinking of borrowing a friend's or taking the node to a friend's to test things out. I have IGMP turned on. I'll have to do a little research to figure out how to deal with the VPN config issue and to see whether the Node and controller are on the same VLAN. But thanks! I hope one of these solves the problem.

With iOS… a couple of things.
In settings Wi-Fi, select the SSID for the network you are attached to and make sure “Private Wi-Fi Address” is turned off.
Also that local access in enabled…
Don’t worry about VLANs as you would have had to configure your Router.

Ok, so "Private Wi-Fi Address" was enabled. I disabled it. Local access was enabled. I deleted and reinstalled the app. Still having the same issue. I really appreciate your helping me with this. Do you have any other suggestions while I figure out how to test with another router? Although I do have one device using the 5ghz SSID (a roku stick), my phone and the node are both using the 2.4 SSID. IPv6 is disabled (something I read on the forums suggested this be disabled, but it was already). And, right, there are no VLAN / Bridges on the router.

Is the slowdown for streaming service files or local files?

Streaming service. Another bit of info that could be of some help: When I use Tidal Connect natively (on the Tidal app), I get the same 12-second buffer that I get when using the BluOs controller with either Amazon Music or Tidal.

It may be the DNS setting. See: https://developers.google.com/speed/public-dns/

Brian, I was wondering about DNS but 12 seconds to resolve is a lifetime in computing, wondering if the Armour security is still an issue (even though not on).
Perhaps see if there are any firmware updates for the Router?
EDIT
There a Router test called Blufferboat, this shows how a Router reacts under a load but may highlight some issues. Also running a Speedtest on the iPhone using the App nPerf would be useful.

As part of this whole process, I did a factory reboot and firmware update on my router, and just confirmed that I have the latest firmware. I'm a little reluctant to change IP addresses on the router, mainly because I don't really know what I'm doing or what other issues that might cause. I did follow the link Brian included and looked at the instructions. My DNS Server on the router is already using 8.8.8.8 and 8.8.4.4 (there's a third ISP listed there, too). Plus, I'm a little reluctant to fiddle with these kinds of settings, since I really have no idea what I'm doing and what issues this might create that I wouldn't know how to resolve. I can't find ANY Armor setting (disabled or no) on the iOS app or in the web user IF. I definitely do not have an Armor subscription. I read a couple of posts saying that there's no way to get rid of Armor since it's built into the firmware. If that's causing the issue, then I'm not sure what to do. As I said, I did a complete reset on my router just last week. Finally, I ran the nPerf test (results below) in the room where the Node is, rather than right next to my router.

At this point all I can suggest is trying the NODE at your friends house as you planned.

Thanks for the help so far. I'll report back once I do that.
