Hi Guys,

Been trying to sort this issue via the VM forum and I currently have a new Superhub on it's way. However I've just posted the message below on the VM forum but wanted to copy it to CF too for any advice anyone may be able to give regarding my question about the downstream channels -

--------------------------------------------------------------------------

Just a quick update, the existing Superhub has rebooted itself again and gone back to default settings.

Looking on the connection page I have 5 downstream channels as follows -

Downstream Channels
Lock Status Modulation Channel ID Max Raw Bit Rate Frequency Power SNR Docsis/EuroDocsis locked
Locked QAM256 80 55616000 Kbits/sec 299000000 Hz 6.9 dBmV 43.2 dB Hybrid
Locked QAM256 79 55616000 Kbits/sec 291000000 Hz 6.9 dBmV 43.2 dB Hybrid
Locked QAM256 81 55616000 Kbits/sec 307000000 Hz 7.1 dBmV 43.3 dB Hybrid
Locked QAM256 82 55616000 Kbits/sec 315000000 Hz 6.8 dBmV 43.3 dB Hybrid
Locked QAM256 83 55616000 Kbits/sec 323000000 Hz 41.6 dBmV 44.0 dB Hybrid

I know that when the tech visited the other week, he said I only needed to worry about the first 3 channels (79 - 81) for my connection but can anyone advise wat channels 82 and 83 are for?

The only reason I ask is that channel 83 always seems to always have a really high downstream power level and the last couple of days my Superhub has remained stable in modem mode but on checking the connection settings yesterday, channel 83 was been at around 7 dBmV. It has now shot up again to 41.6 dBmV and the Superhub has rebooted again.

I am therefore putting 2 and 2 together (and possibly making 5 as I'm no tech but like to think I know a little about these things) but am wondering if it is this channel 83 that is the cause of my problem as I only ever had 3 downstream channels in the past and have never had an issue with the Superhub. The two new channels appear and my Superhub starts rebooting everyday.

Is this channel 83 the channel for the 100MB broadband? Was the tech who visited the other week actually correct?

Grateful for anyone's advice although I will still try the new Superhub once it arrives.

Cheers
