I believe the PanV2 Beta version being referenced is actually 4.49.11.4073
@spencerlhasa, you can edit the title of the thread and your original post to reflect the correct version number.
Since you are testing a Beta version, some issues are expected. All Beta Bugs should be reported within the Beta thread that announced the release of the Beta Firmware so that the Devs can pick up the issues from there. They won’t be looking for Beta Bug reports elsewhere in the forum.
There have been other reports of Xfinity supplied routers being difficult with devices. If you search the forum you will find some recent posts of users having issues with the MAC Filtering function.
