​​ I have no Internet access. ​​​​I've noticed that the US and DS buttons on the modem are blinking, which they didn't do before. What does this mean?​​

​​The modem's lights are a visual indication of its current status. It is normal for your US/DS (upstream/downstream) lights to flash briefly while establishing a connection. Continuously flashing or blinking US/DS lights indicate that the modem is unable to establish a connection due to poor or no signal.​​

​​ ​​

​​Typical reasons for this are:​​

​ ​
• ​ ​

  ​​There is a service outage.​​

  ​ ​
​ ​
• ​ ​

  ​​There is a wiring misconfiguration.​​

  ​ ​
​ ​
• ​ ​

  ​​The modem is defective.​​

  ​ ​
​ ​

​​ ​​

​​If you are experiencing this condition, first check for a service interruption by:​​

​ ​
• ​ ​

  ​​Using the ​​​​XFINITY​​​​ ​​​​My Account mobile app​​​​.​​

  ​ ​
​ ​
• ​ ​

  ​​Logging into your​​​​ ​​​​Comcast account​​​​ ​​​​and clicking the​​​​ ​​​​check for service interruptions​​​​ ​​​​link.​​

  ​ ​
​ ​
• ​ ​

  ​​Visiting the​​​​ ​​​​Xfinity Status Center​​​​.​​

  ​ ​
​ ​
• ​ ​

  ​​Calling 1-800-COMCAST (1-800-266-2278) or 1-800-XFINITY (1-800-934-6489)​​

  ​ ​
​ ​
• ​ ​

  ​​If you've registered your mobile phone number for ​​​​Comcast ​​​​Alerts, you can text ​​​​OUT​​​​ to 266278 (COMCST)​​

  ​ ​
​ ​

​​ ​​

​​Next​​​​, inspect your wiring.  ​​​​See the​​​​ ​​​​troubleshooting guide​​​​.​​
