Slow & Intermittent Traffic on VLAN - Gold Plus
I have a setup where there the Firewalla Gold Plus is the main router. Off of Port 1 I have 4 VLANs (10, 20, 30, 40). Traffic flow is great on the default LAN. And I don't have any issues with VLAN 10, 20 or 30. Those VLANs are actually mainly for systems that we needed to segment off because they create a lot of broadcast traffic.
But VLAN 40 has 30ish users with laptops and a VOIP phone system. There is an SSID associate with that VLAN 40 as well. But all of the users on that VLAN are having intermittent connection issues. E.g. browse to a webpage that won't load, or loads really, really slow. On a VOIP call that suddenly goes quite and then picks up after 30 seconds.
The only rules on the whole Firewalla are the default ones created at setup. The Active Protect Rules and the Block Traffic from Internet rule.
Everything on the default LAN has no problems - wired or wireless. Just devices on the VLAN 40.
Any ideas how to troubleshoot this?

If you have the same rules applied to 10,20,30, then the issue is likely around VLAN 40's layer 2 side. (unlikely to be firewalla, since firewalla treats the different VLAN's the same)
Have you tried to reboot whatever on VLAN 40?
When user having issues, does the web site eventually load? did you check if it is DNS problem?
And lastly, start a long ping from a device on VLAN 40 to firewalla and see if it is LAN or WAN issue.

Thank you. With the router I had in place before Firewalla I was not having any issues. That's part of what made me think it was the Firewalla (just installed over the weekend).
Yes, I have power cycled every device associated with the VLAN 40.
The website sometimes loads in a browser. It's really intermittent. Sometimes it just times out and then other times it loads a partial page and then other times the whole thing will load. Always slow though. Tell me what you mean when you say check DNS problems. Is that reported somewhere I'm not seeing? The DNS for that VLAN is set to DNS 1: 8.8.8.8 and DNS 2: 10.10.40.1. Should I be doing something different there?
By long ping do you mean simply how long the ping test runs? What would tell me if it's a LAN or WAN issue? Pinging only shows me the milliseconds it takes to get a response from the device I'm pinging. Also, when I look at Internet quality, it shows me max latency at .6 with .3% packet loss. That's for everything running on this Firewalla.

Does this happen to all the devices on VLAN 40? if it is just PC/Windows, and they are running antivirus, try to turn off the local port scan feature on these boxes. (tap on the big plus button, then tap on "Device Port Scan", turn everything off or just turn off the devices on VLAN 40)
