as much as i want to ask if its your router lol it sounds like something gave in the kernel man. Have you tried reflashing your kernel or switching kernels? i had the same problem when i first started flashing stuff, so i reflashed everything from the radio to the kernel and then the ROM three times and that seemed to do the trick. just saying doesn't hurt to try reflashing a new kernel or even the same one. wipe cache/dalvik cache 3X, flash new kernel and it should work. if not, your WiFi part of the radio might have given out (known to happen)
