Why is the speed of light 299,792,458m/s? Would the universe be different if the speed of light were higher/lower?

Why is the speed of light what it is? If photons are massless, then what's stopping light from moving at infinite speed? ~~(I understand that the mass of light is more complicated than yes or no, but that's about all I know)~~

Furthermore, if c were different, would there be any significant change in our daily lives other than changing our internet speed?

Well the mass of light is actually a simple no. It has none. And the speed at which massless things move is the speed that links units of space and units of time. It's the speed that says 1 light year in distance and 1 year in time are the same "length" in space-time, so to speak.
