Thanks 'linksys' owner
Since I’m moved in I have been using the ‘default’ SSID which works fine if I sit by the window, but doesn’t work good when I’m sitting on the sofa, because of the signal strength.
Today someone has setup ‘linksys’ in this neighborhood and its signal is very strong. Now I switched to that and am enjoying the Japanese TV show over the net. I don’t know who you are, but thanks!
