I agree with the recommendation to add a router extender. I had the same issue with my separate streamer and DAC. I purchased a Eero 6+ extender after the one extender I got from my wi-fi provider stopped working. The technician from the provider recommended it over their own extender. I run an Ethernet cable from the Eero to my streamer. Drop out problems solved.
Weiss DAC 204 hiccups
I very recently acquired a Weiss DAC 204 which I am streaming Amazon HD Music to via a Bluesound Node 2i. The DAC sounds great and is a huge improvement over the Bluesound and Hegel H190. However, I am getting hiccups once in a while. I have connected the Bluesound to the Weiss using a Cardas Parsec Coax cable. Unfortunately, I do not have a choice but to use WIFI. I have had no WIFI stability issues in the past. Seeking help. Would a streamer like a PS Audio Airlens solve the problem. I do not want to spend much more on a streamer than an Airlens. I have been very pleased with Amazon HD, but recognize I might have to switch to Qobuz since very few streamers support Amazon HD. Thank you in advance for advice.
