I purchased an Arris G36 and set it up, but I kept having my connection dropped a few times throughout the day. Returned that router because I saw some posts saying that Arris did not work well with Xfinity. Went and bought a faster more powerful Netgear ACX80, set it up and it dropped connections randomly also. Returned that and bought a Motorola MG8702, set it ups and it drops its connection randomly throughout the day.
The one thing I noticed is in the event log all three routers showed the same critical errors:
- SYNC Timing Synchronization failure - Failed to acquire QAM/QPSK symbol timing
- No Ranging Response received - T3 time-out
- Started Unicast Maintenance Ranging - No Response received - T3 time-out
- UCD invalid or channel unusable
I see a lot of posts about this issue, but not a lot of success stories. I will try tomorrow the suggestions of replacing the splitter and see what happens.
This is what my Motorola MG8702 is reading:
