Hello Folks,

Perhaps you can help me. I have found that my new ADSL connection with Be has been having connection issues.

Steam games that ran happily on my old Virgin connection, now occasionally fail to connect, give me a connection lost error, or drop me out in game.

Also I have has a few instances of my modem loosing connection to the internet for around 30 seconds before reconnecting.

The line stats are as follows; however I am not sure what I am looking at.
Can anyone see any obvious issues?

Uptime: 0 days, 0:04:22

DSL Type: G.992.5 Annex M US 56

Bandwidth (Up/Down) [kbps/kbps]: 2,044 / 18,768

Data Transferred (Sent/Received) [kB/kB]: 0.00 / 0.00

Output Power (Up/Down) [dBm]: 13.0 / 18.0

Line Attenuation (Up/Down) [dB]: 9.0 / 18.5

SN Margin (Up/Down) [dB]: 6.5 / 6.5

Vendor ID (Local/Remote): TMMB / BDCM

Loss of Framing (Local/Remote): 0 / 0

Loss of Signal (Local/Remote): 2 / 0

Loss of Power (Local/Remote): 0 / 0

Loss of Link (Remote): 0

Error Seconds (Local/Remote): 4 / 0

FEC Errors (Up/Down): 0 / 0

CRC Errors (Up/Down): 0 / 0

HEC Errors (Up/Down): 3,173 / 0


Many Thanks
 
Not sure about your isp, but with bt, they play around with your line speed frequently for the first couple of weeks to try to determine the best speed vs error rate. For the dsl phy to change speed, it has to retrain, which would cause the line to drop. 30 seconds would be about the time the phy would take to retrain.
Do the lights on the modem indicate a dropped line when the interruptions occur?

It could have course also be a slightly broken wire.

I suggest you contact your isp's tech department, especially if it continues for more than 2 weeks.

Obvious problem: your uptime's 4 minutes.
Have you got the modem at the master socket, with no extensions? That's the first thing you should do.

Do they hell. If your connection's unstable the DLM might increase your target SNR margin to fix that but they aren't "playing around" like the ISPs would have you believe. It's purely reactive.
 
Thanks for the quick replies.

The modem is connected to the master socket by the front door to the flat.
I have looked about for a test socket but cannot see one.
No other telephone equipment is connected to the line. I use the line solely for internet.

The modem is connected to the master socket with the short wire Be provided, and a brand new filter that they also supplied.

My virgin connection was cable before hand as well by the way.

I pulled the following information from the routers logs, I hope this can help:

I will have a look at the master socket now as per your link marmalade.

Thanks

The test socket is behind the master socket; you need to take out the two screws and remove the faceplate. If there isn't anything behind the faceplate then the master socket is ancient (like over 25 years old) or that isn't the master socket at all.
 
Ok I have investigated further. The socket I believed to be the master is in the hall by the front door. I cannot see where the cabling goes from this socket, it disappears into the wall.

There are two other sockets in the flat, an identical one to the first- in the bedroom, this is linked to a NTL box on the wall located in the lounge. Unfortunately I am unable to test either of these to see if they work as I do not currently have any phone equipment :(

The NTL box on the wall in the lounge has TV out ports, and two telephone ports. I had assumed that both this box and the one in the bedroom leading off of it were dead as NTL is not currently active in the house. Now I am thinking that this is the master socket.

I have taken it apart, and there is no test socket inside. However there are two wires coming in from outside of the property marked 3 and 5. I suppose that these are the main telephone lines. Would it be safe to assume this is the master socket?

I will get hold of a telephone to test the connectivity. If this proves to the master socket then I may look at extending some solid core twisted pair to the router in the hall from this socket.

In the last 18 hours I have had 12 local resyncs and 3 loss of signals as reported by the router:

Uptime: 0 days, 18:10:47

Can I put this down to faulty wiring on my side of the connection?
