Slow speeds after moving house

[Mouseroo]

Hi Sebby,

Many thanks for the prompt reply 
I may be able to dig out my old router, but that poor old thing was getting a bit 'twitchy' which is why I replaced it.  I'm sure that nothing sinister has happened to my current router during the house move, and it has served me faithfully for a couple of years at my old house, so I'm tempted to rule it out of the equation.
But just to be sure, if I can find the old router (and make it work with a bit of percussive maintenance), then I'll give it a try.
Failing that, I'll get straight into IDNet tomorrow.

Thanks again for your help.  Have a well earned karma 

[Sebby]

No problem.

Like I say, I'd be extremely surprised if it was the router, so if it's a pain to get the other router out, I wouldn't bother.

IDNet will be able to advise you further, but I think we've safely ruled out there being an internal issue.

Thanks for the karma, and let us know how you get on.

I agree with Sebby! The fact that plugged into the test socket your sync speed is still low for what would be expected for your attenuation (my guess 5-6mb), there must be a problem on the line.

If you point support at this thread, they will be able to see what you have done so far and get BT to test the line. Whether or not BT admit there is a fault is a different matter!

[Sebby]

Whether or not BT admit there is a fault is a different matter!

Yes indeed. The results from the test socket aren't atrocious per se, but given the attenuation, they're very poor. If any ISP can get BT to take an interest, it's IDNet, so you're in good hands, Andy.

They may be constrained by the 10-day training period, of course, but these figures are so far out of kilter with the line attenuation, I'd hope even BT would admit all is not well.

Thanks for the information, everyone.  I have just logged a call with IDNet and pointed them to this thread, and mentioned that I would post some more speed test and router stats results.

I plugged my router back into the upstairs extension socket and ran another BT speedtest.  Here are those results:
Test1 comprises of Best Effort Test:  -provides background information.
    IP profile for your line is - 135 kbps
    DSL connection rate: 352 kbps(UP-STREAM)  192 kbps(DOWN-STREAM)
    Actual IP throughput achieved during the test was - 120 kbps

And here are my router stats:
ADSL Link               Downstream  Upstream
Connection Speed    192 kbps      352 kbps
Line Attenuation      48 db          15.5 db
Noise Margin            8 db            6 db

[Sebby]

The results from the extension socket are, quite frankly, an absolute joke. Whilst we proved that your internal wiring is degrading the ADSL signal a fair bit (you managed to achieve a sync rate that was at least verging on sensible in the test socket) it's clear that the problem lies a lot deeper, and is exacerbated by the extension wiring.

Hopefully the fault will be a nice easy one, somewhere in BT's network (most probably the cable to your property). Like I said before, if any ISP can get BT to sort it, it's IDNet.

[Lance]

Those really are painful stats!

Hello again,

IDNet chased up BT for me and their testing concluded that there was nothing wrong with my phone connection 
They advised me to leave my router plugged in to the master socket for upto 3 days.  It has now been plugged in for about 4 hours, and the BT speedtest shows that my downstream profile is indeed increasing 
Here are the results:

Test1 comprises of Best Effort Test:  -provides background information.
    IP profile for your line is - 135 kbps
    DSL connection rate: 448 kbps(UP-STREAM)  4576 kbps(DOWN-STREAM)
    Actual IP throughput achieved during the test was - 116 kbps

And my modem stats:

ADSL Link          Downstream     Upstream
Connection Speed    4576 kbps    448 kbps
Line Attenuation      26 db       8 db
Noise Margin          10 db       20 db


What I am confused about is the actual throughput speed.  Why is this still so slow?  I am using exactly the same equipment I used at my old address (where I was averaging over 6meg).  Should I expect the throughput to increase over the next few days?

Thanks in advance.

[Sebby]

Welcome back, Andy. Well it looks to me that BT have done something as your stats are good and you have a good sync. It could be higher with such a good attenuation figure, but that's for another day. 

Your actual speed won't be any different at the moment yet as the profile has not had a chance to update from 135k. You should find in a couple of days that, assuming you hold this current level of sync, the profile will update to 4000k.  8)

Let us know how you get on over the next few days. Hopefully your issue is sorted, and it's just a matter of time before the profile adjusts.

Hi Sebby,

That's great news, thank you! 
I'll see how things go over the next few days, and with any luck, I'll be able to download the hundreds of megabytes of updates which my poor old laptop is waiting for - REALLY didn't want to try it whilst 135kbps was the best speed I was getting 

Out of curiosity, does it affect your profile / sync / stability if you turn your router off at night, or do most people tend to leave them on (even if all attached PCs are powered down)?

Thanks again.

[Sebby]

Theoretically, it shouldn't make a difference. People tend to leave their routers switched on (myself included) because rate-adaptive products can be hit and miss sometimes and cause you unnecessary hassle. Plus, that's what routers are designed for.

As you are waiting for your profile to change, I'd recommend leaving it sync'd for the time being, just so the DLM sees the line as stable. After that, if you want to switch it off at night, that's okay.

[Mouseroo]

OK, will do.

Thanks again for all your help - it's greatly appreciated! 

[Sebby]

It's a pleasure.

[Lance]

If you are on a less than perfect line, I certainly recommend keeping it turned on. However, on a perfect line hitting 8128 no matter what time of day sync is made, turning off at night is fine

[Rik]

I wish.

[Malc]

I wish.

Probably worn your line out

[Rik]

Only my fingers so far...

[Inactive]

Probably worn your line out

OUCH !!!!

[Mouseroo]

Good news!

I have had my router connected to the master socket for 2 days, and the speed is starting to increase!
The BT speedtester results:

Test1 comprises of Best Effort Test:  -provides background information.
    IP profile for your line is - 3000 kbps
    DSL connection rate: 448 kbps(UP-STREAM)  4128 kbps(DOWN-STREAM)
    Actual IP throughput achieved during the test was - 2429 kbps


And my router stats:

ADSL Link                Downstream     Upstream
Connection Speed    4128 kbps    448 kbps
Line Attenuation      26 db          8 db
Noise Margin               10 db          23 db

Just ran another test at speedtest.net, and got a tad over 3meg    Progress!
Would like the speed to increase to over 4meg over the next few days, but after spending a week at 130kbps, I shan't complain too loudly 

Thanks again to everyone for their advice.  Have a good weekend.

[Lance]

Your sync speed of 4128 will give you a profile of 3500, which is 500 higher than you have at the moment.

It's worth mentioning that your noise margin appears to have been increased from 6 to 12, which will have an adverse effort on your sync speed. If you can keep the router connected with no loss of sync for 15 days, the target will drop by 3db to 9, and this will help give you a higher sync.

[Sebby]

Things are looking up, Andy. Your profile still needs to move a little. The throughput looks a little low for the current profile, but let's see what happens once it's at 3500k like it should be.

As Lance says, try and leave your router sync'd for 14/15 days then reboot it and hopefully your target SNRM will have dropped 3dB. Repeat this once more and you should be down to the default level of 6dB. This should give you quite a bit more sync.
