Latly (past 2 days), my powerbook keeps getting disconected from the local area every now and then and signs back on. I have a wireless router that connects to my pc, that sends the signal to my powerbook which is real close by. It never did this befor, and i decided i would just let it slide the first few times, but now its getting more annoying then ever. What is the cause of this? I already made sure everything was pluged in correctly and everything, and I can't seem to find the problem...
