I still cannot fathom how on a continent that right now has more cell phones than landlines and has actually innovated new uses for cellphones that Lagos' wireless Matrix sucks. That's ridiculous and stupid.
There are few areas in Lagos where there is intact infrastructure or wired systems - and since the city is wedged between undeveloped jungle and the ocean, to connect to the world-wide Matrix, it would need multiple towers connecting to satalite systems. Who controls those towers? How can they make a profit on them? This isn't a free public service! There isn't a government-maintained wireless system... Who the heck is crazy enough to want to build a new tower? And guarding that tower from scavengers, thieves, rival gangs, rival warlords, etc, would be a constant and expensive issue. So for areas that have a satalite hookup, the gangs/warlords/etc make sure
they can profit on it somehow--generally by "taxing" anyone they see with a commlink. If you can't afford the 'tax' what do you think happens? The gang ends up with a commlink they can resell somewhere else.
Next, consider that a Mesh Network only works on active nodes - hidden and passive nodes do not function as a mesh-network router. People in Lagos don't walk around with their commlinks in active mode generally.
Add in that many commlinks in Lagos are DR 1, with a signal of 40 meters, and you'll see why the mesh network is said to fluxuate with the commutes and traffic--the mesh network exists on major thoroughfares, marketplaces, and more affluent neighborhoods, where there is enough active commlinks to connect back to a place with a tower. However, outside those areas, there's little electricity, and old-school vehicles without active nodes, hence, very few periphrial nodes, reducing the mesh-network even more. The further you go from the traffic-heavy areas (where people have commlinks in active mode, and hence, are part of the mesh-network), the fewer nodes there are in the mesh-network. At some point, it becomes unreliable enough to be unusable.
So, yes, some people in Lagos have commlinks. And yet, yes, the wireless Matrix sucks. And yes, an area with a strong wireless network at noon might have no mesh network after everyone goes home after dark.
