Recurring Broadband Interruption

My broadband connection has started to go down regularly every 10 minutes or so. It comes back up after a short time but then goes down again, etc etc. I have just changed the router for a new one, thinking that may have been the problem, but it had made no difference. The new router is a TP Link 150 MB. Assistance needed urgently!

Re: Recurring Broadband Interruption

welcome to the BT community forum where customers help customers and only BT employees are the forum mods

in order for the forum members to help please can you post the adsl stats from your router may need to 'show detail' to get all stats (if hub enter 192.168.1.254 in your browser and navigate to adsl or use a-z, if netgear enter 192.168.0.1 or tplink 192.168.1.1) and run  btspeedtester  (MAC users may have problems). when first test completes then run diagnostic test and post the results .


are you connected directly via a filter to the NTE5 master or test socket or to somewhere else? Is the master the only phone socket in your home?

Have you tried the quiet line test? - dial 17070 option 2 - should hear nothing - best done with a corded phone. if cordless phone you may hear a 'dull hum' which is normal

Someone may then be able to offer help/assistance/suggestions to your problem

Re: Recurring Broadband Interruption

At the master socket:-
BT diagnostic page gives IP PROFILE 7.15Mbps
DSL connection rate 5.44-0.45

Stats             UP DOWN
SN Margin   31  16
ATTn           18  35
Max Data    448 5440
Data Rate   1168 6208
CRC  623, 12080

NB. our exchange is ADSL Max only.

 

Master socket is not the only phone socket in the house, but router was connected directly to it for above test.

 

Quite line test completed : line is quiet

Re: Recurring Broadband Interruption

you profile is to high for your conenction speed - not sure which is correct but don't think it's the profile

 

can you conenct direct to test socket with filter and repost stats.  what router are you using?

Re: Recurring Broadband Interruption

Hi, I'm a neighbour of the original poster. He may have escalated the case to forum mods but his modem (TP LINK) stats are similar to mine in all respects except Attenuation (downline).  His values of 38db (35 at the master socket) compare to mine of 28db.  Perhaps his line takes a different route to the exchange (not that I know whether 7odd db is anyhting to worry about).

 

One question. IP PROFILE. What is the affect of this being too high (if any)? Thanks. (our exchange is ADSL Max ONLY).

 

PS. my modem is a  Thompson.

Re: Recurring Broadband Interruption

if profile is inconsistent with your cionnection speed then there is something wrong and probably will result in a drop in conenction  you can check the correct profile for your connection speed here 

check profile

Re: Recurring Broadband Interruption

this link explains about IP Profiles http://www.kitz.co.uk/adsl/IPprofile.htm

your attenuation affects your connection speed as this link shows http://www.kitz.co.uk/adsl/max_speed_calc.php

Re: Recurring Broadband Interruption

Thanks guys. So my (not very educated!) guess here would be: (for 20CN)

- the sync(connection or rate) speed of 6208 implies that the IP PROFILE should be nearer to 5000 (rather than its current 7150)

- if the IP PROFILE is too high then traffic "bottle-necking" at the exchange virtual paths can occur

- I assume that this "bottle-necking" can result in dropped connections (but I'm guessing on that one!)

We'll see what he forum mods come up with.

Re: Recurring Broadband Interruption

your profile is set by your conenction speed and normally for 20cn changes almost immediatley the connection speed change downwards but can take 3/5 days to recover when your connection speed increases.  21Cn profile chnage immediately up or down and is 88.2% of conenction speed

 

if profile to high on adslmax then it will reset with conenction drop to correct level based on the current conenction speed - just an error nothing to do with VP
