There's nothing wrong with wifi
It's actually really helpful for learning matchups, from what I hear.
Learn exactly how to handle your recovery and how to space your moves properly, those are the two biggest things imo. Recovery because it's somewhat tricky for Wolf and if you suck with it you're going to die a lot more than you should, and spacing because Wolf has excellent range and it's basically a must for any character. Get the basics going on, and then you'll be able to develop an effective style of play yourself
