Sometimes i can connect to my Edimax Router but then signal becomes low then it dropout. I can not also detect my network most of the times. I already tried a clean install of Mac OSX 10.5.5 that comes with the Laptop, but the dropouts is still there. My iPhone and another Windows OS Laptop can still connect to my router.
