@Big8D no, thats not a problem. In order to run DOCSIS 3.1, a certain percentage of the users connected to any given CMTS require the CODA-4582. At or above that threshold %, DOCSIS 3.1, which uses OFDM can be enabled on the CMTS. There is a bandwidth tradeoff as the freqency spectrum allocated to DOCSIS 3.1 will become exclusive to DOCSIS 3.1. @RogersDave can correct me here if I'm wrong. The remaining frequency spectrum will remain as is for DOCSIS 3.0 operation.
So, for now, your modem remains in DOCSIS 3.0 mode, which isn't a problem.
Please let me know if the swap manages to bring up both OFDM channels. If not, I would wonder if there is an issue with the CMTS to which your modem is connected.
Maybe I'm missing something (I'm in a still-3.0 area), but I thought the initial D3.1 deployment was only one OFDM channel, with another to come later as D3.0 capacity gets reallocated...
@RogersDave can you clarify? Has anybody observed two OFDM channels?
I am getting internet stalls and in the logs I am seeing this:
SYNC Timing Synchronization failure - Loss of Sync;;CM-QOS=1.1;CM-VER=3.1;
Lost MDD Timeout;;;CM-QOS=1.1;CM-VER=3.1;
Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received - T4 time out;;CM-QOS=1.1;CM-VER=3.1;
No Ranging Response received - T3 time-out;;CM-QOS=1.1;CM-VER=3.1;
MIMO Event MIMO: Stored MIMO=1 post cfg file MIMO=-1;;CM-QOS=1.1;CM-VER=3.1;
Is there something going on?
When you say that you have a 100 Mb/s connection, is that to mean that you're on a 100/10 Mb/s internet plan, or that the connected port LED at the back of the modem is green, which would indicate a connection to a 100 Mb/s device. Amber denotes a 1 Gb/s interconnect with the device.
For the wifi, have a look at your wifi environment with inSSIDer. See who you're competing with in the 2.4 and 5 Ghz band. The link below is for the last freebie version of inSSIDer. It doesn't properly display the 802.11ac networks in the area so you won't see the complete picture so to speak. For anyone else running 802.11n networks, those you will see. There is a newer licenced version which does display the 802.11ac networks, so, if you do happen to use 802.11ac, its worth the $20 US to see who else is possibly using the same channels.
For 5 Ghz networks, try using channels 149 and higher as they have a higher allowable transmit power, 1 w versus the lower 5 Ghz which are limited to 50 or 200 mw depending on when the device received its Industry Canada certification.
