Hub3.0 Diags

old poster here, same old problem still. Local external box is a repeater coax fed varying signal levels particularly when the sun shines.

Getting frequent disconnects again. They do get into the Hub log (UTC timestamps)

Why do these not register in the Tn counts?

Upstream bonded channels
Channel Channel Type T1 Timeouts T2 Timeouts T3 Timeouts T4 Timeouts
1 ATDMA 0 0 0 0
2 ATDMA 0 0 0 0
3 ATDMA 0 0 0 0
4 ATDMA 0 0 0 0

Is that why the auto tools always say nothing wrong, and I have to get a tech out, who checks everything and then says it is a networks problem who never fix it properly?

Re: Hub3.0 Diags

Everyone's log displays errors like that and although at first glance you would think the world is coming to an end, upon closer inspection you see that all the errors are happening within the space of a minute or two and then normal service resumes.
The T errors don't register willy nilly. Each category reflects a specific type of error which you obviously aren't suffering. If you are having problems with frequent disconnects I would suggest you post your power levels and setup a BQM graph if you haven't done so already. It is all great diagnostic evidence for the tech if you need to call one out.

Re: Hub3.0 Diags

I must learn how to do the graph, my problem is unstable power levels, they vary between +9 and -6 when connected and your hit refresh, quite a high error count, but for that also the absolute numbers not important, they increase in bunches.

Re: Hub3.0 Diags

I also NEVER see any errors here when i should, got to be a firmware issue.

Re: Hub3.0 Diags

Still must do the graph,again!, I used to know how. My problem before was the local cab as usual, but had to get a tech out to check the house and report to "Networks", was better for a while now gone again... But meanwhile the hub 3.0 has had a firmware update, upstream power has the correct magnitude (was out by factor of 10) and errors do get logged, reset on power on it seems. But reporting via VM website is much harder. Of course the modem is online when tested, can't inititiate the test when not, grrr

Code:
Upstream bonded channels
Channel	Channel Type	T1 Timeouts	T2 Timeouts	T3 Timeouts	T4 Timeouts
1	ATDMA	0	0	17	0
2	ATDMA	0	0	11	0
3	ATDMA	0	0	0	0
4	ATDMA	0	0	0	0
I do actually still have TBB monitor, setup 5 years ago, but now IP address has changed!

Just update the graph to your new IP.

Re: Hub3.0 Diags



So how do I get VM to take action? When it works it works, when it doesn't it doesn't. Problem is and cable amplifier in the external box again I suspect, the downstream power when working is +6, but just before it drops out is goes negative.

Re: Hub3.0 Diags

keep the graphs and screenshots of the post rs errors. When it goes down try to use the VM service status page on your phone to run a test, let it see your connection is down and book and an engineer. Trying to explain it to India and getting somebody out will be like banging your head against a wall.

Re: Hub3.0 Diags

Still have problem, when the sun shines the power levels bounce up and down from + 9 to -3, and get loss of sync. Managed to book an engineer yesterday, very pleasant but wouldn't believe me or what other techs have said. Replaced my white hub 3.0 with a new black hub 3.0, and cable/isolator. But same problem again new IP address/ monitor. But unable to contact them again. the website which has replaced any intelligent life form doesn't even know that you can use Broadband by cable, I'm not using wifi...

"No network issue found
Good news, we didn't find any network issues. However, the problem may be with your in-home connection.

To help fix the issue, you can check the WiFi performance of all devices connected to the Hub."

Going to see what BT fibre offers I have available.

I see this a lot with water-ingress (into F-Connectors and/or coax), working with satellite internet systems.

Likely a wet joint or cable damage somewhere. For starters have you checked your driveway for cable damage? - I've stuck a lawn edger through my own before (thanks to Nynex for planting it 1inch deep!)

Like BT, they won't believe you until they see signal issues happening in-person. Modem's don't generally ever die unless really old and the demod dies.

I'll get a network engineer out to it if I can see a problem, but your signal levels look OK at the moment. Send me a PM next time they drop.
