I use a mesh network (TP Link S4's) to extend the network from starlink in my house. which is quite large and has some thick walls in 2 places. Using this scanner it looks lie I've got great signal but in reality I have a huge drop off in speeds - it comes into the main room at +200 Mbps but by the time it gets to my office via mesh I'm lucky to get 40, normally its less!!!!
