Power cycle the modem/router. If you have a separate modem and router cycle both. What's happening is that your devices can make a connection to the router, but the router can't connect to the service.

  • Your broadband modem is experiencing connectivity issues? My wireless works fine with my iPad and iPhones. But then I try to connect it to my Windows 7 desktop, and it says that it's experiencing connectivity issues? I have the Ethernet cable hooked up to the main router, then my wireless, then into the computer. I've tried restarting them both at the same time, but it's still having the same issue?
  • Switched from iphone to galaxy s3 and I'm having issues with imessaging? All my friends with iphones are having issues texting me. I don't know what to do. I know it's because of imessage. If I turn that off on my end (My old phone and my ipad) will that fix it?
  • My laptop says 'limited connectivity' to my Internet access? My mother just recently bought five new iPhones, one for each of us in our family. We have Comcast Xfinity as our Internet data plan, and I'm wondering if the arrival of our new iPhones took up the limitation of Internet access in our house. Before we had iPhones, we just had three computers and an iPad in our house.So, is it the iPhones that took up most of our Internet connections, and if so, how do you expand the limitation of devices for our Internet connection?
  • Ipv6 connectivity says no internet access? My pc is connected to internet using cable. Lately, it became very slow. As compare to my wireless connection to my iphone. When i'm checking, ipv6 connectivity at my modem status says that no internet access. Is this the reason? How can i fix it?
