Been having intermittent connection problems, 3 or 4 times a day modem will go into 1 of 2 flashing light patterns for about last week or so

1. Ready flashing slowly for 30 sec SYNC on , Ready off and SYNC flashing rapidly for 30 seconds, then repeat

2. Ready flashing slowly

This usually last 20 to 30 mins then clears

all timings are guesstimates

Modem is NTL 250 on 10Mbs in RG6 area, not a new install been working fine for years till now

downstream
Downstream Receive Power Level : -8.6 dBmV
Downstream SNR : 38.6 dB

upstream
Upstream transmit Power Level : 45.0 dBmV
Upstream Mini-Slot Size : 2

See things like this in the log ( can't access modem from browser once flashing starts)

Any works etc that might account for this ?

downstream power level is very high you better call Tech Support(should be around -/+ 3dBmV)

Also:
(3) No Ranging Response received - T3 time-out
I have had this before and it wouldnt connect to the network so kept rebooting and waited and eventually it worked.

Downstream Receive Power Level : -8.6 dBmV Low but outside normal range
Downstream SNR : 38.6 dB Spot on


Upstream transmit Power Level : 45.0 dBmV Spot on

Your power levels are within operational parmeters but you should not lose connection as you describe so a call to Tech Support is required.

Be careful of reading modem logs, because what happens when you reboot your modem is that every single update for that modem is received at the same time giving you those worrying logs.

Virgin also disable most of the updates as they are not required so making it look even worse.

It would have flagged up as an area fault when they ran some checks.

This sounds like the same problem that I have been having for almost two weeks now.

have you still got that really high power level of 18 dbmv?

Yes. Just posted on my own thread.

Unprompted - and it would seem unimportant to them since they have omitted to show it on the bill - gave them benifit of the doubt on june bill since so close to billing date, but still nothing - muppets

I had a similar problem. It took 3 visits and 4 weeks to fix. In the end the problem was with the box in the street and not at my address. It happened straight after they upgraded the lines ready for the 50MB roll out.

Don't suppose its anything like mine? For the past day and a half, the modems (enet & send) lights have been flashing constantly, even with the PC's and router turned off. Tried several reboots to no avail.

Also our STB keeps pixelating, so I assume the problem is connected. As yet I havn't called 151, as several other people in our area (Ipswich IP1) have the same STB problem. However they don't have BB.

Is it worth giving 151 a call?

100% yes. Get the ball rolling and get an engineer alerted

At least find out if its a known problem and explain that its unacceptable. Log the days you have been without BB then when you get it back on give them another call to explain you are not paying for the service between these dates.

I did and they agreed. They credited my account there and then.
