If you really want to stay travelling for a long time and you want to stay for extended periods in places which don't have amazing internet you should consider getting some other skills. Going from national capital to major population centre is all well and good but you will only see amount of the planet that way. Consider welding, electrical or diesel engine repair as skills you can get employed with pretty much anywhere. Sure, you may not make a consultants salary but those sorts of skills generally pay more than enough to live on comfortably practically everywhere in the world.
Food for thought if you want to spend a lifetime on the road instead of just a year.
Or you could just try to work on gigs that pay well for 3-4 month a year in a place that has awesome internets and dont work while being in places that dont have decent connections. Better than getting into real employment situations anyway.
