Maxwell’s equations do predict the existence of electromagnetic waves that move at the speed c. But that’s all Maxwell had to say - that there was this wave phenomenon we call electromagnetism, and its waves move at that speed. They are simple and fundamental. However, while he knew that, at the time, light and electromagnetism were considered to be separate phenomena, and so Maxwell did not say that c was the speed of light: the only thing his equations told him was that c is the speed of propagation of that ‘electromagnetic’ wave that came out of his equations. However, he is best known for his equations that unified electricity, magnetism and light. Maxwell’s Equations in Present Form March 18, 2016 by Marie Christiano Maxwell's equations mathematically link electricity, magnetism and light.
They say some thing but definitely not every thing enough to interpret this issue of light speed. A look at the equations through the years.

However, manipulating the equations directly results in a wave equation, which describes the propagation of EM wave. All that we have learned can be summarized in the equations known as Maxwell's Equations, together with the formulas for the electric and magnetic forces on a charge.One of several ways Maxwell's equations can be written is shown at the right, just so you can say you have seen them.
Measurements designed to measure the speed of the Earth through the aether conflicted with this notion, though.
The nineteenth-century Scottish physicist James Clerk Maxwell made groundbreaking contributions to many areas of science including thermodynamics and … In 1864, there were 20 equations solving for 20 variables, now we have 4.
Maxwell's equations describe electricity, magnetism, space, time and the relationships among them. What did that mean? How Maxwell's equations came to light Mahon, Basil; Abstract .
In other words, Maxwell did not postulate the existence of EM wave when he was constructing the four equations. James Clerk Maxwell [1831-1879] was an Einstein/Newton-level genius who took a set of known experimental laws (Faraday's Law, Ampere's Law) and unified them into a symmetric coherent set of Equations known as Maxwell's Equations.
There was nothing in those equations about light, and radio waves were completely unknown at the time, so the existence of electromagnetic waves was also completely unknown.
We have completed our study of the laws of electricity and magnetism.
The electric flux across a closed surface is proportional to the charge enclosed.
