If you are on a work, school, hotel, or hospital public WiFi:

  • Check with your network administrator to make sure online services such as Grammarly are supported and not intentionally blocked.
  • Note that many public networks have limited bandwidth.

If you're using a cellular data network or satellite internet:

  • If possible, try a different network. Cellular data and satellite internet connections commonly have slower connection speeds than cable internet or DSL.
