IPV4 Internet access not working after Xfinity update
My IPV4 internet access no longer working since an Xfinity update that I believe was installed around 12am on 2/11/2025.
I have been dealing with this on and off again issue for almost a year now. I have had 3 replacement Xfinity routers (two XB8 & one XB7)
and none of them have resolved the issue. Back leveling to the XB7 unit was at the direction of the support tech 6 months ago.
The issue happens on 2 different Windows (Dell & HP) computers and a Sony PS5, whether wireless or ethernet connected.
I have figured out a work around by signing into the router and doing a resave on the attached device's settings. This re-establishes
the connection and somehow now assigns the proper IPV4 addresses needed for the device to connect to IPV4 internet sites.
Nothing is changed on the PC's or PS5 to get the IPV4 internet access working. Only the router is touched by the work around.
It is a [Edited: Language] to have to keep doing that to get a working internet connection on these devices.
IPV6 connections always work.
Xfinity phone support has been useless. They waste my time performing their level 1 support steps or sending a tech to check my equipment
with the same results, NO SOLUTION!
I need to speak to a technical person at level 2/3 support who understands IPV4 & IPV6 address assignments and can help trouble shoot this Xfinity issue.
It is definitely not a PC/Windows or PS5 issue, as it has been working solidly for the 6 weeks and no changes we made to these devices prior to the IPV4 failures restarting. Prior to this 6 week period I had to use the workaround for the past 5+ months.
Has anyone else out there found a solution to this as I have seen multiple postings detailing similar issues?
Xfinity, can you get me in contact with a real level2/3 suppoer technician?
