"Jeffy's Wifi Problem!" is the 359th episode of SML Movies. It is also the Third Most Viewed SML Video of all time.
The video starts with Jeffy playing Rocket League. Jeffy scores a goal and starts trash talking. Mario then comes into the room and tells Jeffy to do his chores, but Jeffy say's it time for him to do his chores. Mario asks again and Jeffy says he's playing Rocket League and to not disturb him. Mario says he is going to change the wi-fi password if Jeffy doesn't do his chores. Jeffy responds "I don't give a s**t", prompting Mario to change the Wi-Fi password from 1234 to ABCD and Black Yoshi's Call of Duty stops and disconnects.
Black Yoshi is horrified, saying "The woofis has been disconnectiss!" Mario then tells Black Yoshi the new password but tells him not to tell Jeffy. Shortly later, Jeffy screams “DADDY!”. Mario comes in and he was notified the “game” Jeffy was playing froze. Jeffy then tells Mario to tell him the new password. Mario continues to tell Jeffy to do his chores, and once Jeffy does his chores. Mario will tell him the new password.
Jeffy's chores are to do the dishes and dust the whole house.
Once Jeffy begins his chores he starts off with the dishes, he begins throwing plates on the floor, including a mug.
After Jeffy is done with the dishes, he starts dusting the house. Jeffy is first seen beginning dusting the red couch, and the PS4 controller, and whacks Mario with it. Mario gets annoyed by Jeffy when he hits him with the feather duster and asks Jeffy if he's all done with his chores. Jeffy answers yes to the dishes and dusting the whole house. Mario then makes Jeffy see how well he's done on the dishes.
Back in the kitchen, Mario notices that Jeffy didn't wash the dishes, but Jeffy thinks he was only supposed to do the dishes, suggesting only the plates and the mug. Mario asks Jeffy where he put the plates, Jeffy says the cabinet, Mario then checks the cabinet, but nothing is inside. Jeffy then remembered that he put them on the floor. Mario catching along, he looks at the floor only to see the shards of plates scattered all around the kitchen floor. Mario then asks that if Jeffy broke anything else, Jeffy is seen dusting from before in a different room, pushing vases with the feather duster. Mario then tells Jeffy he is grounded and is not getting the password.
Jeffy yells at Mario saying he did his chores and deserves the wifi password, and threatens to poop in the sink if he doesn't get it (which he did before). Mario still says no.
Later, Mario gets a phone call, Jeffy being behind the couch while on the phone acting as an internet company person. Jeffy tells him he has a security breach on his account. Jeffy however finds this suspicious so he look over the couch and found Jeffy. Mario yells at Jeffy so Jeffy calls the electrician. The electrician (Brooklyn T. Guy) asks what he wants and Jeffy says he doesn't know his WiFi password. The electrician asks why Jeffy can't just ask his parents and Jeffy responds that his Mario won't let him so Brooklyn T.Guy then goes to talk with Mario.
Brooklyn T.Guy then went to the couch with Mario and Mario ask what he is doing here and Brooklyn T.Guy forgot so he then decides to show pictures in his phone. He asks him for the WiFi password and Mario says he can use his so he does. Then Brooklyn T.Guy shows him 2 pictures of the Leaning Tower of Pisa and Mario says they are both way off.
Brooklyn T.Guy, upset about this, decides to sell Mario a foosball table. Mario asks the price and he says that it is only $500 so Mario buys it. The foosball table is then quickly delivered. Mario asks how it was delivered so fast and Brooklyn T.Guy tells him he has super fast shipping and then admits that the foosball was his. Mario gets angry and Brooklyn T.Guy tells him he has to leave
Brooklyn T.Guy then goes back to Jeffy and Jeffy asks if he got the WiFi power. Brooklyn T.Guy says sadly no and Jeffy wants a refund but Brooklyn T.Guy says he can buy a foosball table for only $300. Jeffy asks if it is fun and he says that it is really fun so Jeffy buys it. Jeffy then goes to Mario and simultaneously says, “I JUST GOT A FOOSBALL TABLE!” Mario and Jeffy argue a little on how they got scammed.
Jeffy then goes back upstairs, angry. Bowser Junior then comes and Jeffy that he could’ve just use the neighbor's WiFi. Jeffy then throws the foosball table off the table, and goes back to playing Rocket League.
Black Yoshi finally gets some paper and goes to Mario for the password. However, when Mario says “A,” Black Yoshi writes “Z," and when Mario says “B,” Black Yoshi wrote “Q,” and the video ends.
