The whole Wi-Fi subsystem has its own firmware. It outputs audio via I2S to XMOS. Other than turning the thing on/off WiFi module operates “standalone” on its own software. If stutter is present with Wi-Fi but not LAN, the issue is 99% certainty poor Wi-Fi.
Stutter on WiFi but non on wired simply means WiFi spectrum is congested and the signal poor. If you expect generic Wi-Fi to carry full fat audio (not MP3 or the like) without stutter, you need a clean 2.4GHz spectrum. For serious audio, hardwired please, Wi-Fi signal quality is not reliable. But that has nothing to do with iDSD Pro. If it works on a hardwired network, but not Wi-Fi, the problem is the Wi-Fi signal. An easy way to see if you have a good chance for major Wi-Fi problems is to open your phone’s Wi-Fi screen and count the number of networks shown. If more than one and your router has not been set to use “non-default” Wi-Fi channels (you would know if you changed those settings, if you didn’t they are 99% default), you have problems.
Almost all routers default to the same channel. We believe in 2.4G and the highest rate at “n” – ONE router/device pair in an empty spectrum has enough bandwidth to stream 192/24. Even having anyone surfing the web on the same Wi-Fi may be too much. Neighbours networks on the same channel steal bandwidth, as the spectrum congests.
