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.
