# Can You Solve This Restaurant's Ridiculous Equation to Get Free Wi-Fi

Some restaurants don’t want to offer free Wi-Fi, and that’s totally their prerogative. Maybe they’d rather have customers focus on the food than their fantasy football teas. Maybe they don’t want a bunch of freeloading screenwriters ordering a coffee and hogging a table for the entire day. Maybe the restaurant owners are just like, “Get a better mobile data plan!” But whatever the reason, not having free Wi-Fi is better than having free Wi-Fi but being jerks about it by having an impossible Wi-Fi password.

A Thai restaurant in San Antonio, Texas, called Yaya’s is making headlines for having a Wi-Fi password that is proving impossible for the Internet to unravel. A handwritten sign on the wall lists the “Wi-Fi Password” as a complex mathematical equation – a summation to be specific:

Bars and eateries forcing people to solve math equations to access Wi-Fi networks is something we’ve definitely seen in the past, but what makes Yaya’s equation so frustrating is that even after it was posted to the social news site Reddit, no one’s been able to figure out how to access the network, even people who seem to know what they’re talking about. “This looks a lot like a summation of a binomial probability density function,” wrote one Reddit commenter. “I strongly doubt the divider between N/m should even be there.”

As a result, speculation is that whoever wrote out the equation for the restaurant may not be a math genius at all, perhaps copying it incorrectly from another source. “Given the mistakes, it looks like something written by someone who doesn't understand what they're doing,” wrote another Redditor.

The Reddit user who original posted the image of the sign, Joshua_Glock, claims to have gone to the restaurant multiple times to try suggestions left in the over 400 comments included on his post and has yet to find one that works. The Huffington Post even reached out to the restaurant yesterday to get to the bottom of this issue but hasn’t gotten a reply.

Whatever the password actually is, let’s hope the restaurant’s owners have Internet access because they might be interested to know their ridiculous password is gaining them tons of notoriety online. Possibly an even bigger question than what the password is: Will the guy who wrote it get fired or get a giant raise for being an expert at troll marketing?
