Re: ADSL Sync Problems


[re: deleted] [link to this post]
 
So the problem was that he had to change his username/pwd, as I originally suggested?

He should be getting about 14.5 Meg on that attn. on ADSL2+. Attn. is up 4 dB due to going from G.DMT to ADSL2+. He should be connecting on ADSL2+; ADSL2 (only) is only beneficial on long lines, but perhaps it is using it cuz his speed is extraordinary low.

Need to find out why this is. Looks like an internal wiring problem, esp. as speed was low before the upgrade. Has he tried it with all phones etc. unplugged and router plugged into master socket with no extn. cable? Hope he is using filter? Could try changing that in case it is faulty. Has he tried removing the ring wire?

Can he now get those router settings I asked for? There might be some mileage in playing with them.

(Can't keep swapping thread. Can we keep to this one please?)

In reply to a post by SteveDH:
about 4 months ago my dad was syncing at about 6000kbps down and 512 kbps up
then it suddenly dropped to about 300kbps down 64 kbps up
Did anything happen around the time of the "suddenly"? New kit or phones?

Got a set of the stats now it is connected?

It is possible if the sync never varies on reboots, that ISP has locked the connection to a 300/64 setting

Does all point to wiring, like a phone plugged in that does not have a filter (easily missed when behind furniture)

If AOL are saying that the speed is fine, then any other advice they give I would end up laughing at

Re: ADSL Sync Problems


[re: MrSaffron] [link to this post]
 
no the password was correctly set at the start, it just seemed to take a few days to get a stable connection, maybe it was negotiating down to that speed.

The results are the same with all other phones and anything else that can be unplugged, unplugged, and the router plugged into the main socket (which is the old style so no test socket). I have also checked with different filters and routers.

speed-wise it sort of depends on who you end up talking to, but I have been told that is the speed he should expect, dispite having 10 times that before and all the speed estimates (where you type in your phone number) agreeing that it should be faster.

No one wants to know about line stats, and you still get asked to do countless speed tests dispite the fact that the issue is the sync speed.

If it does look like internal wiring, any suggestions on how best to handle it, otherwise I need to give my dad as much ammo as possible for when he next phones them.

Try forcing the mode to standard ADSL (g.dmt) and getting the stats then (if it syncs!).

I'm not sure I can do that with this router, but the stats at the start of the thread
i.e.
noise margin upstream: 12 db
output power downstream: 14 db
attenuation upstream: 18 db
and
noise margin downstream: 14 db
output power upstream: 10 db
attenuation downstream: 27 db
at
300kbps down 64 kbps up

where when it was on g.dmt

I wish I had the stats for when it was connecting at 6000/512 but as it was working ok then there was no real need to record them..
thanks
Steve

My apologies, I missed that. Don't bother trying to force g.dmt.

I can only echo MrSaffron's suggestion of giving AOL a time-period to sort the problem or be considered in breach of contract.

[re: MrSaffron] [link to this post]
 
ok stats at the bottom of this thread as you have now probably seen, however thats one thing I'm worried about, maybe the culprit is being removed, but as the connection may be locked to that speed, it stays the same, so it just gets plugged in again.

I'm thinking that as it seems to take a couple of days to get a stable connection that maybe it tried at the top speed again and then took a while to get to a speed that was stable.

however the speed does now fluctuate a bit
its now 1541 kbps / 66 kbps
although an hour or so ago it was
642 kbps / 84 kbps
which also implies the connection isn't very stable
although the logs not particularly helpful as it doesn't show any relevant information about that

If it were my house, I'd be disconnecting all the wiring too, apart form the incoming wires and testing just into that socket.

This is what a visiting engineer should do, and then fit an NTE5 if this improves matters.

As its LLU my usual tricks with BT Wholesale won't work
