Dell N1524 is a Gigabit switch with a 10Gbit uplink capacity (which is useless for NDI). Unless you set it wrong, you should not have problems to transport up to 7/8 NDI streams. Manageable switches require network knowledge.

I have experimented with great success NDI over Wifi (5GHz) with multiple Android and iOS devices with Newtek and Sienna apps. I was surprised it worked smoothly with 4 simultaneous devices connected on a pretty basic AP (Asus RT-AC68U).

I find the technology very mature and reliable although it's pretty recent. I use NDI in my productions for more than 8 or 9 months, never had a problem.

I think your AP should be connected to the switch (not to your modem).
You have very good equipments, you should not experience issues for NDI. But you don't give details about the issues you encounter so it's difficult to figure out what might be wrong.

Hey thanks Kane, I read somewhere to turn off DHCP Snooping, that helped a lot, none of my NDI sources would show up in Vmix or the NDI toolkit at all. I think i got the switch working right now, i just did a test and it was not dropping to many frames at 1080p 59.94 over the 10gbe NDI. I just got to plug my Ubiquiti into the switch and check that.
