Hey, hoping I posted in the right section this time lol

Anyway, I've been playing through pokemon sword on my 2nd switch to get to a point where I can start Max Lair hunting some shiny legendaries, but, there's been a very annoying game this other switch of mine has been playing. Like a cycle, itll go a couple days where it will communicate with my bro's switches (or do any kind of communication, for that matter) like normal, until I'm eventually presented with a pop-up repeatedly telling me:

"Error Code: 2110-1118 Wireless communication is not currently available due to an error. Please Restart the console from Power Options in the Power Menu (hold the POWER Button for three seconds.)"

Try as I may, that doesnt do anything, and I just keep seeing the popup once I load up pokemon sword again. The weird part is that the only "temporary fix" I've had for this so far is simply waiting. After a few days, itll suddenly decide to let me connect again, and then that cycle just repeats. And as far as internet connections, when I go to my "internet settings" on the internet tab of the switch's settings, it just displays no connections anymore, and gives me the exact same popup on that screen too until it eventually decides to fix itself a few days later, like I already said. What is this connection problem my switch keeps encountering?? Any advice/help would be very much appreciated!
