Hub resyncing when connection being used

Go to solution

Firstly I have enjoyed a adsl sync speed at 19Mb (thruput around 17) for years, recently this is now consistently syncing at 17M and "fast" has changed to "interleaved". I guess someone has been playing with the cabling looms between me and the exchange!  BUT one anoying thing is that my bthh4 always used to reboot during the night, now it does it during the day. Whilst I understand that if something is going on in the network, I understand a need to reboot. However looking at the WAN logs it is always termination(user request) which means its the home hub 4 that in its infinite wisdom decides to reset - thats ok but why doesnt someone design it so it doesnt resync when the connection is actually being used. Its great when using internet banking that the dam thing decides it wants to reboot!  Is this normal? At least it ought to be considered in a redesign/refirmware or something.

Re: Hub resyncing when connection being used

your connection should be stable 24/7 and resets as you describe are a problem that needs reolved

 


in order for the forum members to help please can you post the adsl stats from your router you may need to 'show detail' to get all stats (if hub enter 192.168.1.254 in your browser and navigate to adsl or if HH4/5 then go to troubleshooting then logs and you are looking for 2 line together when hub last connected to internet and they will show your connection speed and noise margin or if netgear enter 192.168.0.1). Then run  btspeedtester  (MAC users may have problems). when first test completes then run diagnostic test and post the results ( do not reset the router).


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

Thanks IMJ. The HH4 is directly connected into a proper adsl faceplate (not the filter dongle thing), and I did a quiet noise test, BT also aledgedly tested it. The performance is within scope. But wishing the ultimate performance I am just concerned that my dslam sync has reduced from 19Mbs to 17Mbs (not thruput) and the home hub reboots sometimes when in use and that fast has changed to interleved just concerns me. My original snr was 3db rather than 6db.

Further when I used a Netgear router I used to keep the same IP address for a month, and it just changed BT side and not by rebooting. Unfortunately I had to change to BT HH4 because my Netgear didnt have IPTV and I now use BT Sport via the BT box. Mike

 

There doesnt seem to be a way of attaching my router log.

interleaving is turned on to stabilise the connection as is the snr increase to the standard BT default of 6Db

I tried to copy/paste the log, but it was too many characters. I will try some of it.

Regarding Interleve, I understand but there was never instability before so I can only assume something has happened in the local bt network by someone shaking the wires, not sure there is anything to do for that.

The logs show a reset on the 18/7 but as the following days logs are not there you cannot tell if connection has been stable since then or whether there has been further resets. Drops in connection can result in latency being changed to interleaved instead of fast to try and stabilise connection

OK I will edit the log to show resets.

Re: Hub resyncing when connection being used

Go to solution

Continued: Some of the above seem to be the hh4 deciding to reboot, some of the others appear for some other reason.

Is it possible to foce a change from interleved to fast and force a reduction back to 3db, they were my connections for a year or so. Nothing has changed this end, I can only assume a degrading in the network.

Re: Hub resyncing when connection being used

No

 

you cannot force a change of interleaved to fast or a reduction in noise margin - both controlled by DLM

 

A stable connection will few errors will eventually get DLM to change latency and lower noise margin
