There have been a couple of interpretations of this, I believe.
I favor the interpretation where you can brick anything that has wireless turned ON.
For security conscious individuals (Shadowrunners & > PL2 peeps is what I usually go by), anything that does not have a wireless bonus will be OFF by default. They are judicious about what equipment they keep wireless ON. For everyone else, they're blissfully unaware of the dangers of hackers since GOD keeps them "100%" safe and leave all their stuff turned wirelss ON, whether it provides a bonus or not, so they don't miss out on software updates, etc.
But that's just my interpretation. I think it allows for a pretty fun game where the team can pull a few tricks on non-trained people but may have a bit of a tougher time with better trained opponents. At the same time, it also allows them to protect themselves from a lot of run-ending hacking attacks that could otherwise occur.
ETA: After going through it a few times, I believe we've come to an understanding that DNI is required to do anything that would otherwise require manually doing something to the gun (Taking a free action to mentally change the firing mode, ejecting a clip, firing the gun without pulling the trigger, etc)
ETA2: So, in your case. The eyes are not wireless on. The Vision Enhancement and Smartlink are Wirelss ON if you want the extra bonus fro each. The VE and Smarlink can be hacked, the eyes cannot.
