Random disconnects around Midnight

AbyssUnderground · 08-07-2008, 12:11

Hello all,

The last week or so I've been getting random broadband disconnects at around Midnight to 2am time. My graphs on several occasions show this. The only way to get it back on is to reboot the modem. The SYNC and RDY lights stay on and the ETH and UP lights flash occasionally when disconnected.

This only started when we had VM TV installed last week. I have checked the signal levels and everything seems fine, but I was worried about the SNR, it was much higher before.

Downstream Receive Power Level : 5.48 dBmv
Downstream SNR : 28.38 dB
Upstream Transmit Power Level : 48.00 dBmv

Is there any way to improve the SNR myself? When we had it installed a piece of the original cable was removed (since we had excess) to run to the TV. Is it possible the connections crimped on the ends aren't very good and are ruining the SNR? Bear in mind our broadband has been reliable as you can get the last 6-7 years and never randomly disconnecting, ever.

I'm sorry to say I have to agree that your post didn't seem particularly helpful to AbyssUnderground.

sometimes when things are put simply... they don't always come across as being "particularly helpful"...

It's like asking if your water pressure has gone up the swanny? we can't.

What the?!?

Downstream Receive Power Level : 0.18 dBmv
Downstream SNR : 27.27 dB
Upstream Transmit Power Level : 48.00 dBmv

The levels just plummeted... Tho we do have a thunder storm happening at the moment, could that be why? Still I feel it getting more unstable by the second.

You should just unplug the modem and leave it for a couple of hours.

Well if you can't help why say anything at all?

Ah good some helpful advice.

Now I hope someone can come up with some help for the OP.He really needs some sensible suggestions and I'm sure there is someone,somewhere on the forums who can help.

Have you called broadband faults? They might be able to see something from logs that show and issue. It you've just had TV installed your signal could be just on the edge. Maybe there is some sort of update, possible for the EPG of TV triggered around that time, which creates just that bit too much traffic?

Ok
On thread
Firstly
Check if your UBR is being upgraded.
It does sound strange that this happend after TV Installed. Any splitter used by the tech can reduce signal levels dBmv as it introduces a resitance.
As always best call tech support to check. If req'd a tech will call out to change the levels in the cab or check connections are secure,

Well I have posted the signal levels and the only one that looks bad is the SNR and that only dropped when we had the TV installed. What gets me is why it -only- does it at midnight to 2am and not during the rest of the day.
