The key word above is "unlicensed". And the other key word -- not present -- is "knowingly". But the analogy breaks down because you don't need a license to use the Internet. Consequently, in most cases you will not know, and cannot reasonably be expected to know, about legal violations. If you let your buddy use your home wireless while he's staying with you for the weekend, and he commits, say, a fraud, or blackmails someone, you are not legally responsible for any of it unless you participated knowingly in some way. Of course, that you didn't know may be hard and expensive and unpleasant to try to prove, but that's a different question.
Ummm... you might be liable under your service agreement with your ISP. Most of these have all kinds of restrictive clauses re. not letting others use your connection, copyright infringement, assumption of liability, yada, yada, yada. We all violate these, all the time, but there are times when that might catch up with someone.
The term "criminally negligent" really has no role here. Negligence is in most cases a civil not a criminal offense. There are specific crimes. There is aiding and abetting. There may be criminal negligence in unrelated cases where you have a duty to secure something or protect (or not harm) someone and fail to do so (e.g. you leave your car in a position to roll downhill and it hurts someone, or you are willfully blind to a danger to child for whom you should be caring, or you act with such inattention so as to kill someone). But in the USA ***you have no legal duty to secure your wireless***. None. You can leave it open, just as you can leave your window open and let people enjoy what you are playing on your stereo (modulo public nuisance law, and copyright rules against some types of unlicensed public performance). Thus there can be no negligence in leaving it open, at least absent specific knowledge that a person intends to do a specific thing.
You may have a civil liability to secure your wireless under the terms-of-service agreement with your Internet provider. Well, maybe not to "secure your wireless" but to prevent unauthorized use of your connection to the service provider - which could be accomplished in other ways.
