High power level on one downstream channel
 
After getting sent to back of line for bumping my own thread after 6 days and breaking an unwritten rule on the VM community forum I dare not add to it again.

My superhub has 5 downstream channels locked, 4 around 0dBmV and the 5th is at 43dBmV.

Is that a bad sign, worse than all being a bit high? There's a load of stuff in the event log too but I don't know if that is safe to put on a public forum.


Cheers, Matt

Firmware bug. Reboot it.

T looks like it's sorted it. I was hoping it might have been why the superhub is so slow.

Bern told there are no utilisation problems and the power levels look fine but I only get 10Mb downloading blueyonder game demos.

It's not a question of breaking rules it's just the way the VM techs tackle issues on the board - they work with the oldest. If you bump your own thread it just has the effect of putting you at the back of the queue it isn't some sort of punishment.

The techs show up as red iirc so if you find one they've answered you can gauge the wait time reasonably accurately. It's usually 2-3 days but I expect it has grown as VM continue to give out higher speeds (and more importantly STM cap levels) willy nilly without any actual capacity increase to support them.

It was 6 days without a response to the information one of the techs had asked me to post. The way it came across was that I should have known better and tough it was now going to be 2 weeks.

Some people on there have said it's oldest thread first and others have said it's oldest since a tech responded. What happens if you posted in my thread? Do I go to the back of the queue or only if I respond to what you wrote?

If a post is made in the thread, you go to the back of the queue.

If they've fixed that BS it isn't before time. I haven't looked at the VM board now in months but it's still where I'd report a problem other than a complete loss of service in preference to talking to a call centre.

Last time I reported a problem over there I was completely ignored.

So as far as I'm concerned it's no different to talking to an offshored call center.

Both appear to be a complete waste of time.

Re: High power level on one downstream channel
 
yup.

But there is hope. For some reason whenever ive managed to speak to Scottish dudes which has luckily been often they always go the extra mile for me. Their not all script readers, theres some in the profession who have the ability to understand, get on the level and use common sense.

I'll second that thenry. If you're lucky enough to get someone in Scotland then you've a far better chance of some actual help.
