I've looked at some of the other posts, but I think mine is enough different to warrant starting fresh. I live in San Diego, within the main city limits. My home is a single-story, wood-frame structure. It does, however, have a metal roof, so indoor wireless reception was poor. I was provided with a Samsung 4G LTE Network Extender. Based on its requirements to be near a window for the GPS antenna, and near my Wi-Fi router for the Ethernet connection, I installed the extender in my office, which is at one end of the house. Performance in the kitchen, and dining and living rooms, at the opposite end, is unreliable -- sometimes there, sometimes not. 611 suggests relocating the unit to a more central location in the house, but the above-mentioned requirements make doing so just shy of impossible. Any thoughts?
