Hello, recently I've been having problems connecting to mi wireless connection at home. It sometimes doesn't appear in my room and I need to move to the kitchen, then come back for it to keep connected, though it will mostly disconnect. If trying to reconnect, it gives a connection timeout. I know it's not my router signal, because my ipod touch 1st gen can connect from my room, also my wii. It kind of feels like if the power of my macbook's wireless has gone done, because wireless networks of neighbors don't appear anymore, though they appear in system profiler for some reason. And at school, on a specific class, the network won't appear, but if I connect to it manually, it connects full bars. Pretty weird. Any ideas ?
