It's around 15β20 meters and three walls from the router to the apartment's back room. Two other houses sit "windows to windows" to mine, and my router's signal was simply disrupted by them. I spent a considerable amount of time trying to resolve the issue of poor Internet by attempting to replace the wireless router, upgrade the antennas, switch channels, relocate the router, etc. The change was negligible. As soon as I heard about Powerline technology, I went out and bought the TL-WPA4220KIT. Complete resolution of the issue (higher real speeds measured).
