Firmware Update

Received and email from online.communications@alerts.comcast.net stating I needed to update the firmware on my Gateway router within 7 days, else it will no longer be able to connect to the internet. The link given is a Google address: [Removed Potential Malicious Link]

Is this a legit email? A problem is that I'm out of the state, away from home, probably through next Wednesday.

... The link given is a Google address ... update the firmware on my Gateway router ...

This is some sort of scam. Do not click! Note:

  • Comcast/Xfinity would most likely direct you to  a Comcast,com or Xfinity.com address, not Google. 
  • Users cannot update firmware on their Gateway routers, only Comcast/Xfinity can do that.

I have not seen any emails sent out regarding firmware updates. All of our firmware updates to Comcast modems get pushed automatically over night if there is a new firmware update that the modem needs.

I just got the same email.  It's deceptive because the "from" email (see above) looks legit.  My Comcast email program marked it as spam, so I was suspicious already, but appreciate this forum and communication to confirm. Thanks!

Received May 20, July 23 and July 27 several remails on this. I followed instructions though my box did not light up

[Removed Potential Malicious Link]

How to install: The update will be applied automatically when you click the button above. Your Gateway router will restart once. The process takes 5-10 minutes. Do not unplug your router during this time.
Having issues? If you experience any problems with the update, please contact Xfinity support at 1-800-XFINITY.
Only did it once. I do not think it took. Had a folder but it was empty and deleted it. Hope you catch all of the bad people. Glad Xfinity does their own firmware.

I have also received the same exact message. Is this legit or not? It says that we have only 7 Days in order to do this update. Is this an actual update or is this a scam? I see on here that some people are stating this is a scam and then others are actually trying to download this!. [Edited: "Inappropriate Language"] 🤷‍♀️
