3D printing help

I’ve loaded my 3D printer with a new filament and although it’s the same supplier as the last lot I was using I’m having problems with it.

Basically the layers are very visible from the side and they don’t seem to be sticking together properly. I’ll try and attach a photo.

Any suggestions for what needs tweaking? I’ve thought of raising the extrusion temperature so it sticks better and increasing the feed rate so there’s more plastic in each layer. Are any of these worth trying?
