Nailed it maybe a more complicated background, perhaps like a frame, on the same note as the Discord banner. Also a background color which is easier on the eyes, and near the borders this monochromatic lighter color fades away revealing the more complex background which perhaps could be integrated to better design the wifi logo.
I think if I remember right, the “beacon” on that background I’m referring to is kinda shaped like the player marker from The Sims? Obviously less is more is also a viable option, I’m not a stickers expert (printing a more complicated picture may be problematic? Who knows). Oh, I should also clarify in my mind the sticker is round.
