Very slow speed, MDD message timeout, SYNC Timing Synchronization failure - Loss of Sync
Hi there - I've been having incredibly slow speeds for a month. Hovers between 35-50 mbps. Called Xfinity, Called Arris Surfboard..Both say its the other sides issue. Powercycled and it corrects a little and then drops again. Don't know what any of this means, but hoping some good samaritan can help me figure this out. Is it a signal issue or modem issue?
What can I do to correct?
