Im using a MBP 15' CD, 2gb ram, week 25. I've had 0 wireless problems for 2 and a half years until randomly a few days ago, my wireless constantly drops and I can't get a stable signal anymore. My router is only about 5-10 meters away. It was fine and very strong up until a few days ago. I am running leopard with the latest update, and wireless was fine for ages until that day. First thing I did was try other wireless networks that were usually fine -same thing, I have trouble connecting and can no longer get full bars. I then uninstalled or removed software I installed/downloaded that day, no difference. I then restarted and upgraded firmware on the routers, and did a software update for my MBP... no change. I changed the router channel to 8 and it improved a little bit, but still, poorer than before. I did a safe boot, i used YASU, I did all that I could find on the web, but no changes. Anyone know whats wrong? I'm still under warranty so ultimately I can get Applecare to sort me out, but I want to avoid giving my MBP away since I can't live without it. Thanks.
