Continuing problems after headend update
We are still experiencing daily T3 errors and frequent streaming drops.
The headend was updated in November. Our modem was misconfigured, and it took weeks to get it properly provisioned.
However, we are not obtaining the bandwidth we are paying for (1.2G) and still have frequent streams dropping.
D/L bandwidth tested at the modem is consistently around 800-900 (was around 1300-1400 before) U/L is 25 - 35 (was 40-42 before).
Can someone please help and get the headend fixed?
There have been no changes at our location -- Same hardware, same cables, all of the fittings are tight, all of the firmware is updated, and everything is rebooted every day.
Still with T3 errors that were never present before the November headend update.
