I like the stripes but I would centre the text to the mark and maybe watch out for the swastika that seems to form as it may be offensive to some

maybe good if the triangles on the hexagon were little pizza slices?

I think that the coffee bean is a nice touch but would take a second look at the typefaces you have combined: https://www.canva.com/learn/combining-fonts-10-must-know-tips-from-a-designer/

I like the signal strength lines! I would maybe consider a different colour choice as the bright colour of the typeface is harsh on the eyes and may not work against some backgrounds

I like the colours but I think that the lines would be cleaned up a little :)
