Incredibly slow connection Sunday

[Dan]

My connection tonight is painfully slow - even to the point I can't get speedtest to run to tell me how slow (seems to sit on "choosing server based on ping").

Is this just me (or users on the Crayford exchange)?

Thanks

[Lance]

I'm guessing by the lack of responses it's just you I'm afraid. Rather than waste time running a useless speedtest, run the useful BT one which will reveal your profile - it may be a low profile cause your slow speed. If you could also post the connection stats from your router that would be great ( sync speed, noise margin and attenuation).

[Dan]

Thanks Lance,

I gave up last night, luckily it's good this morning. I'll use the BT test next time I'm in trouble.

Current stats (when it's working fine) looks like
ADSL Link    Downstream    Upstream
Connection Speed    9438 kbps    1275 kbps
Line Attenuation    25.5 db    11.5 db
Noise Margin    15.00 db    7.0 db

Certainly your connection is showing signs of instability as your downstream sync is low for the attenuation and your downstream SNR is elevated.

A BT speedtest will show your current IP profile.

Hi,

I get brief outages (mostly lasting for seconds) a couple of times a day. Sometimes the router sorts it out, sometimes though I find I have to log onto my router and disconnect, then connect again. I can also tell when I have lost the connection when I've been away from my desk because when I return to my SQL query window it reports the break (only one, it wouldn't tell me how many times).

I had one a few moments ago and have run a BT speedtest. That reports:

Download speedachieved during the test was - 7499 Kbps
 For your connection, the acceptable range of speeds is 2000-7150 Kbps.
 Additional Information:
 Your DSL Connection Rate :9194 Kbps(DOWN-STREAM), 1275 Kbps(UP-STREAM)
 IP Profile for your line is - 8111 Kbps

Upload speed achieved during the test was - 1053 Kbps
 Additional Information:
 Upstream Rate IP profile on your line is - 1275 Kbps

And if I look at the statistics on the router (I have a Netgear DG834Gv5 running V6.00.25 firmware) it reports this (downstream and upstream are the same as Sunday night 2 weeks back):

Port   Status      TxPkts   RxPkts   Collisions   Tx B/s   Rx B/s   Up Time
WAN    PPPoA       19786    32691    0            415    2403   03:42:24
LAN    100M/Full   139827   133778   0            4419   1689   03:42:51
WLAN   11M/54M     36808    22230    0            1817   169    03:43:08

ADSL Link    Downstream    Upstream
Connection Speed    9194 kbps    1275 kbps
Line Attenuation    25.5 db    11.5 db
Noise Margin    15.00 db    7.0 db

We turn the router on in the morning, and turn it off every night (I really don't want to leave it on overnight).

Is there anything I can look at to make the line more reliable? (I'm happy with the speed) When I joined IDNet I removed the bellwire(?) from the master socket. Thanks

My first advice would have to be leave the router on 24/7, that's the way they are designed to work, and the daily disconnects (power downs) will be stopping DLM from restoring your profile.

[Lance]

Additionally with the downstream noise margin at 15db that signifies that the equipment has found instability - possibly caused by the power on/off cycle each day. Keeping the router on 24/7 could result in an additional 2mb+ if the noise margin is given time to drop to 6db.

As for the disconnects, do you know if the router is losing sync or just ppp. I believe you'll be able to tell based on the colour of the lights on the router when the connection is lost.

[Dan]

Thanks Rik / Lance.

I'll try leaving the router on and see if that makes any difference (I'll give it a few days and report back). I've also changed the router's logging to include "Router operation (start up, get time etc)" - see if that records more than just bootup/connected/disconnected/admin logged in. And run to the router when I lose the connection...

It will take up to 5 days of continuous connection for your profile to recover, but hopefully only a couple of days in your case.
