Hi, I used to connect wireless router to my ISP's modem and all worked fine until I decided I do no longer need wireless router and started connecting through ISP's modem. Then around once a week I get disconnected from ISP's modem. Reconnecting does not help, restarting ISP's modem does not help. The only thing that helps is restarting iPad. I do not have this problem with other devices that I connect to ISP's modem.
