Please post the output of 'ip a l' and 'ip ro l' once the system has
this 'failed wireless interface'.

While it seems weird, I doubt it that the problem lies at L1 OSI (i.e.
physical one). See below.

You're configuring a default gateway for both network interfaces, which
is a big no-no, unless you know what you're doing. You also set IP
addresses from the same network, and that is one of the best ways to
have your host's IP routing going haywire.
