So, my man is the tech genius of geniuses. We've lived in lovely old domiciles for years now, super wonderful architecture and attention to detail... complete with loads of layers of lead paint before the latex was added some ten/twenty years ago. Now - I'm not hatin' on lead paint, you'll find loads of older painters that b*tch that the quality of artists paint has gone down since they took it out of our tubes but...
we can't get signal from our wireless router in some parts of our houses no matter WHAT we do. We finally figured out it was the lead paint. Then - we felt stupid because it should've been so easy to figure out.
