ok sorry. no harm in trying this. OP do a pinhole reset on the Hub. it may be glitched. follow these instructions...

Re: Just been upgraded from 10mb to 20mb, but know my internet is slower!
Again, TH - putting people to the trouble of a pinhole reset on the offchance it might work is not good advice. All the router settings so painfully (sometimes) established are lost and this is a humble single channel modem and there's really no need.
Sorry, TH. The first thing that TinyT needs is a forward path attenuator as advised by mon General. |
Re: Just been upgraded from 10mb to 20mb, but know my internet is slower!
id rather try things to solve a problem while waiting for a tech than do nothing worrying about any settings i had set to the hub. again no harm in trying. its not like the Hub will stop working.

Never quite sure what the levels should be but here is another VMDG280 to compare against
Downstream Channel Lock Status Locked Modulation QAM256 Channel ID 148 Symbol Rate 6952000 Downstream Frequency 315000000 Hz Downstream Power 6.0 dBmV SNR 40.8 dBmV ------------------------------------------------------------------------------- Upstream Channel Lock Status Locked Modulation QAM16 Channel ID 4 Symbol Rate 5120 Ksym/sec Upstream Frequency 27400000 Hz Upstream Power 48.7 dBmV ------------------------------------------------------------------------------- Primary Downstream Service Flow Downstream(0) SFID 15334 Max Traffic Rate 21480000 bps Max Traffic Burst 3044 bytes Mix Traffic Rate 0 bps ------------------------------------------------------------------------------- Primary Upstream Service Flow Upstream(0) SFID 15333 Max Traffic Rate 1180000 bps Max Traffic Burst 8160 bytes Mix Traffic Rate 0 bps Max Concatenated Burst 8160 bytes Scheduling Type Best Effort ---------- Post added at 10:03 ---------- Previous post was at 10:01 ---------- lol was just looking for the post I replied to as it had vanished and I seemed to be in another thread altogether. Seems I missed the page 2 link. More caffeine please! |

Re: Just been upgraded from 10mb to 20mb, but know my internet is slower!
Ken - the point I wished to make is that your upstream is working at half speed because you're on QPSK modulation (2 bits/symbol rather than 4 on QAM16). If that doesn't matter to you, fine. I couldn't live with it because of what I need the internet for.

Re: Just been upgraded from 10mb to 20mb, but know my internet is slower!
If memory serves it switches to QPSK from QAM usually when there is an issue on the line.

Re: Just been upgraded from 10mb to 20mb, but know my internet is slower!
Yeah - Noise. 2 bits/symbol allows for more potholes than 4 bits/symbol.

Ehehehe....
