Fixed IP and I attached a pair of high gain antenna to rhe router and ran a 24 hour continuous test without problems.
This sure seems like a wireless thing then.
Even so, I can’t imagine a wireless signal so bad it can’t pass a 192k stream. That seems very wrong. The code just sits in a tight read/write loop from the file to a socket, so there really isn’t anything to not work there.
I wonder if there might be some sockopts that might help. Buffer size or something of that nature?
