Wii U Loses Internet Connection A Lot.

Hey there Nintendo Tech Support community. I'm having a lot of trouble. My Wii U keeps losing it's internet connection! I can get it back by turning my Wii U off & back on again, but eventually it'll lose connection again. I've mainly been watching videos on the Youtube app, but I had the same thing happen when I went into the Eshop, too. If I test my internet connection afterwards it will always fail. The error code I get is 103-1601; Unable to find a Wi-Fi network. It's been happening for a few days now, might even be going on a week or two, & I'm really starting to get annoyed Please, if anyone has any suggestions, I'd love to hear them. I'd appreciate it.
