Last resort: Contact your ISP
If all else fails, consider calling your ISP. Yes, it’s usually one of the most unpleasant things you can do with your time, but it could save you hours, days or weeks of future frustration.
If you’ve upgraded your Internet package and you’re using hardware supplied by your service provider, they can get the right hardware in your hands. Time Warner Cable, for instance, recently rolled out its TWC MAXX upgrades in parts of Charlotte, North Carolina, which call for upgraded hardware. Without a newer modem and router, you may not experience the full effects of the free upgrade.
If it’s any other issue, they can usually help diagnose the problem and deploy a fix. Often, unfortunately, those solutions will come at the expense of your own purse.
