Internet Connection Drop / Online Games / Browsing


[link to this post]
 
Hi folks.

Not sure if this is entirely the right forum, but for months I have been having a problem with my BT Internet.

I use a homehub, at first i used the wireless feature but received quite a lot of disconnects from online games (Bad Company 2 & World of Warcraft). I was also getting complete disconnects where I would be disconnected, open up a browser window (firefox or ie) to receive the message that my physical connection to broadband was OK but it could not communicate with the hub, usually about 1-2 mins after this it kicks back in and I can go back to browsing / gaming.

Unfortunately this is not very convenient, to log back into games / lose scores and generally waste time. These disconnects (where i get the hub message) happen 2 -3 times an hour. I will say though that i get more disconnects playing BC2 then i do WoW. But I still experience the complete cut (with the physical connection message) while playing both games.

I then switched my BT connection to Wired (thinking the wireless was maybe to blame) I switched that about 4 months ago, and sad to say, I am still having the same problems.

I have tried the speedtestbt website, but that does not find any problems with speed (as i didn’t think it would) I am unsure if it is some sort of pack loss or what it is.

Does anyone have any ideas / suggestions?

Also – I did read something about interleaving – and that i may perhaps benefit from asking BT to switch this off (I have checked the BT Home Hub and it is listed as on – however I see no option to disable it.)

Any help / advice appreciated.

Thanks
Kenny

Interleaving makes a connection more stable, at the cost of 10 or 15ms extra latency (ping time). I would leave it on if the problem you have is stability.

Can you find the router statistics page and post the attenuation, connection speed, noise margin, error counters etc here plse. http://www.kitz.co.uk/adsl/frogstats.php

Also tell us how your house phone wiring works and where the router is

Hi Yarwell.

Please find below the information you requested.

Downstream 4,832 Kbps
Upstream 927 Kbps

ADSL settings
VPI/VCI 0/38
Type PPPoA
Modulation ITU-T G.992.3
Latency type Interleaved
Noise margin (Down/Up) 6.6 dB / 6.6 dB
Line attenuation (Down/Up) 47.5 dB / 29.0 dB
Output power (Down/Up) 0.0 dBm / 12.9 dBm
Loss of Framing (Local) 0
Loss of Signal (Local) 0
Loss of Power (Local) 0
FEC Errors (Down/Up) 0 / 4294967258
CRC Errors (Down/Up) 1566 / N/A
HEC Errors (Down/Up) N/A / 0
Error Seconds (Local) 1306


The wiring: There is only 1 phone socket in the house so the BT Home Hub is plugged into that,.

I have connected in each of the following ways

Computers into homehub wired
Computers wireless


Currently its connected into the Hub wired

And i have no kids, pirate or otherwise tongue

Thanks

Latency type Interleaved
Noise margin (Down/Up) 6.6 dB / 6.6 dB
Line attenuation (Down/Up) 47.5 dB / 29.0 dB


so it's an interleaved ADSL2 connection running with a 6 dB target (and actual) margin both up and down. So far so good.

FEC Errors (Down/Up) 0 / 4294967258
CRC Errors (Down/Up) 1566 / N/A
HEC Errors (Down/Up) N/A / 0
Error Seconds (Local) 1306


the "error seconds" means 1306 seconds since it was started in which one or more errors occurred. This sounds a lot but not if it had been on for weeks. Maybe reset it and check errored seconds over a defined time period.

The high upstream FEC errors may be a bug, the 1566 CRC errors fits in with the errored seconds.

If the one socket is the only socket and there's no extension wiring attached I would check the stats with no phone online and the router plugged into the test socket behind the master. No alarms, bells or other phone line type devices around ?

Have a hunt around the web interface to see if it gives you an uptime or online time for the WAN or the ADSL too.

Hi Yarwell.

I conducted a complete factory reset of router this morning.

Please find updated results below:

Note: I am still being disconnected from games.


Line state Connected
Connection time 0 days, 6:33:48
Downstream 5,103 Kbps
Upstream 883 Kbps

ADSL settings
VPI/VCI 0/38
Type PPPoA
Modulation ITU-T G.992.3
Latency type Interleaved
Noise margin (Down/Up) 5.3 dB / 8.1 dB
Line attenuation (Down/Up) 48.0 dB / 29.0 dB
Output power (Down/Up) 0.0 dBm / 12.6 dBm
Loss of Framing (Local) 0
Loss of Signal (Local) 0
Loss of Power (Local) 0
FEC Errors (Down/Up) 0 / 4294967268
CRC Errors (Down/Up) 3065 / N/A
HEC Errors (Down/Up) N/A / 0
Error Seconds (Local) 1



I have not removed the Phones yet or tried to plug straight into master socket , if you feel it is still worth doing this then resetting router again to get more results like above i will.

Let me know what you think.

Thanks

Kenny
