Same here, but the house is a few decades younger, has brick walls and thick reinforced concrete floors. Early WiFi was rough, let me tell ya. At one point, I improvised a directional WiFi antenna out of Styrofoam and precisely cut wires, which actually worked. I tried three generations of DLAN after that, all of which were horribly unreliable and had nowhere near the advertised performance. I'm now moderately happy with a meshnet, which is so reliable that I forgot how to log into it to configure it.
