Hi Eric,
The dejitterit portal was simply beneficial as the proprietor extensively measured end explained why he uses the ARUBA IAP 325 in the modified kit he sells and why wifi 5 (ac) is the last „non-harmful“ (to cabling and equipment) technology. Luckily the Aruba and the AC902 use the ac wifi 5 technology:)
Also, if someone has only one access point in their listening area then the way to set it up is to create two SSIDs on this AP, one on a 5GHz and one on a 2,4GHz channel and give them separate credentials. Then use one of those SSIDs to connect to your TP Link and the other one for the phone (the controller). This will have no wifi interferrence as each SSID is on a different channel.
Actually, the Aruba has a really cool feature – one can block broadcasts from devices in the network. In other words, in my setup, the only broadcast that arrives to the TP Link is from the Roon server. Everything else is blocked. Even the phone (the controller) only communicates to the roon server. I literally have to give it clearance if I want to modify something on the TP link.
Cheers,
B.
