OK, so here's my problem. one day, my internet stopped working for no o parent reason. so, i rebooted my modem, and it came back on. but not like it was, my download speed is now at an all time low, only reaching 3-4 kbps.... that is ridiculous. did my 5 year old modem finally bite the dust? or is there a fix for this? some help would be great PS: the modem is a zyxel p-660r-d1.
