3DS XL Internet problems?

[iovis]

Hey! I recently began using my 3DS, and the internet worked fine for the first few days. However, recently it's been shaky.
(e.g. 1. it'll work in the mornings and turn off in the afternoons and work again in the night)
(e.g. 2. it'll only connect for an hour in the afternoon)
My family's laptops and phones connect to the internet just fine, but my 3DS seems to refuse to connect.
I don't have any metal objects around me, other than the phone and laptop, of course, so I don't think metal is the problem.

Does anyone know how to fix this?

What is your internet provider?

I would suggest you to move closer to the router in your house, or just get another router and put it in your room. I used to have the exact internet problem with my 3DS, but since I got a router in my room there was no more issues.
