Upload Bonding Channels Not Locking

[MLara05]

I just purchased a home and they previously had Xfinity so I went ahead and purchased my own modem/router combo and i'm having issues while uploading/playing online games. I am getting T3 errors/3 bonding channels not locking.

I relocated the modem/router at every output location throughout the house and the problem remains. There are no visible splitters and I went ahead and looked at the connection outside and the wire seem fine "I see previous connections which are no longer in use".

Help is appreciated!

Did you check for service issues? Is your equipment still supported? What the make and model? What's your speed tier? 

We need a lot more details than just what you gave us. Please see Internet Troubleshooting Tips  for more info.

FWIW, there may be an old high pass filter installed on your line that may need to removed by a Comcast tech. YMMV.

@darkangelic 

No service issues, I am on a c3700v2 "still supported" and internet starter.

@EG 

Most likely the issue, is it possible for me to remove/change it myself or does Xfinity have a specific one they use?

Thanks

Edit:

Removed it but nothing changed.

Xfinity has someone come out and the issue is resolved.
