Title: DNS servers
Post by: Golfer on August 01, 2010, 09:55:46 AM
Good morning all!

I hope this is the correct section for my enquiry?

I moved home recently and had to change ISP from Tiscali to TalkTalk.  My Tiscali connection speed was around the 6Mb mark, now on TT it is only around 2.9Mb.  I understand this has a lot to do with distance from exchange/users on line etc. so I think my options to increase my speed may be limited.  Is there a tutorial that guides you through various settings/tweaks that may improve matters?

Also, there is a reference in a recent CA mag about changing DNS servers to speed up browsing.  I did a 'google' but I'm still a bit confused!  Specifically, on my system, I have both TCP/IPv4(local) and TCP/IPv6(limited) installed.  Do I have to change the DNS settings on both or just the latest version? And would I need to change the router settings also?

Thanks in advance

Rich

That's correct,but unless you have moved house then the distance from the exchange is the same no matter who your isp is.

Changing to different DNS servers won't have any effect on download speeds. DNS is the service which converts internet URLs (e.g. bbc.co.uk) to numbers (e.g. 212.58.224.138) and some DNS servers are faster than others; this can affect the speed of loading of web pages, particularly those with lots of embedded links to other pages, such as adverts. Changing to different DNS servers isn't likely to have a dramatic effect on your life unless your ISP's servers are particularly bad.

Concerning your reduced connection speed, the router stats (see UncleUB's link above) may give us a clue, but it rather looks as though you may have been put on a lower speed profile.

Hi both and thanks for the replies.

As I said, I've moved house!  My previous ISP, Tiscali, was no longer available to new connections so I went with TalkTalk (who bought out Tiscali) as they had virtually the identical deal available as I had previously been on.

My old line gave me about 6Mb speed.  My new line gives around 2.9Mb (it's an 'up to 8Mb' deal).  I assume the difference between the two is because I am now on a different exchange than before, further away than before and there is probably more traffic on the line.  What I would like to know, is there any way I can improve my line speed etc from my end, or is it entirely at the ISP's end?  Are there any tweaks I can make that would make a difference?  If it is the ISP, how would I go about getting a better profile/speed? 

The DNS server question is that I found two TC/IP versions installed - v4(set as 'local') and v6(set as 'limited').  If I changed to non-ISP servers, would I need to change the settings in both versions or just the latest one (assuming v6), or could I delete the older version and just use the latest?  Also, would I need to change the router settings to match the connection settings?

I don't like to poke about with things I don't really understand (there lies madness!) without taking advice from you good folks first!

Regards

Rich

Hi

Do you have any internal wiring/extensions that is/are in use.The best way if possible is to plug your router into the main BT socket and monitor your connection for a few days.

Post your router stats on here so they can be analysed,how to do that here

Hi Uncle UB, thanks for that.

Equipment connected to 'first in' line box - no extensions used.  Stats as follows:

Router EchoLife HG520b   (TT standard issue)

ADSL State                            Show Time
Data Path                              Interleaved
Op mode                                ADSL2
Bandwidth down/up (kbps)       3056/793
SNR Margin down/up (dB)         10.0/13.0
Attenuation down/up (dB)        47.0/28.5
Power down/up (dBm)              0.0/12.3
CRC down/up                         37/65503
FEC down/up                         2782/65513
HEC down/up                         625/0
PVC Select                            PVC -0     (only option available at these settings)

Hope these numbers make sense!

I notice that the bandwidth down figure has increased slightly. I gather that this can vary during the day and that it is better to leave the router permanently 'on' as this can also affect the profile?  The router connected 'out of the box' with no config input from me.  I haven't had any connection probs to date, it has been running approx 3 months (hope I've not jinxed it now!) and the line has been stable so far.  Computer runs Vista Home Prem SP2.

BTW - and unrelated - if anyone could tell me how to take a screenshot and post the results I would be most grateful!  It would save a lot of time and pencil lead!

Many thanks

Rich

With a downstream attenuation of 47db you should be syncing around 5500kbps with an IP profile of 4500kbps

Ok! Bear with me! 

So from that, I should be seeing an average d/l speed of 5.5Mb? The IP profile figure means nothing to me I'm afraid!  What would I need to do to get this increased?  My end or the ISP?

Very grateful for your help   :)

Would I be right in believing that you're on the TT Essentials LLU package? If so, the IP profile doesn't apply, because that's a BT IPStream characteristic. But it's true that your connection speed is lower than it ought to be for your level of attenuation. This isn't directly the fault of your ISP - it could be the condition of your line, or your own household wiring. You can read about improving your connection here, (http://www.kitz.co.uk/adsl/socket.htm) but in the first instance I suggest that you try connecting the router to the test socket to see if that improves the connection speed.

Hi Eric, thanks for the reply.  Yes, I am on the TT Essentials LLU package.

The router is plugged into the first entry socket into the property but it doesn't have a test socket.  This socket has obviously been replaced at some point in the past before we took over the property.  It does carry the 'master socket' tag internally however, as we discovered when running extensions to other rooms/alarm system etc.  All of the slave sockets are filtered and when tested give the same levels (more or less) as per the figures above - this also depends on the time of day.  There is no discernible noise on the line and the phone clarity is good when on a call, both when the computer is on line and off line.  We don't suffer drop out problems, just a general slowdown from time to time which, in all honesty isn't too much of an issue as we don't download huge files as a rule.  I have read up on various tweaks to try and improve matters but prefer to get the opinion of those more knowledgeable than me before wading in and making things worse!

As you may have gathered, I only have a vague grasp of the technicalities of these things but am learning bit by bit!

Thanks again

Rich

Hi
You are losing some synch rate ,that is probably in part at least because your Target SNR margin(or its equivalent )is at least 9db. With each 3 db above 6db costing up to 1200Kbps (depending on bit loading).

Hi Jeff - thanks for that.  Is there anything that can be done to improve this by me or do I need to contact the ISP to 'juice' it up a bit?  Also, is there a way to find out what my line is actually capable of supporting?

Hi Zoe, thanks for your reply.

Yes, I'm already signed up to TT's forums and was thinking that was the way to go.  I had a problem getting through to TT Customer Services recently (as in finding it impossible - auto menu cutting me off and them not replying to emails!) and found the forum mods to be very helpful.  My problem was resolved very quickly.  I have switched to Google's servers already and will monitor performance to see if things improve.

As for a speed increase, where do I need to go and what is it I ask for?  My speed isn't dire and I don't suffer from drop-outs etc.  My router stats suggest I should be getting around 5.5Mb but I'm around 3Mb.  Should I be grateful for what I have or is it worth a punt to see if they can beef it up?  I'm a firm believer in fair play - if it says 8Mb on the tin................................!!

Thanks again,  Rich

If you read the T&C's closely you will see its up to 8mb/20mb/24mb or whatever package you are on.

As already stated it depends on your distance to the local exchange as to how fast a speed your line can support.

You can try phoning TT's support,but I wouldn't hold my breath.

Tbh I don't think your problem has anything to do with DNS

I would certainly double check all your internal wiring again.I'm not sure if BT (Openreach) will come and fit you a new master socket (with a test socket)foc,someone else might be able to answer that.

Hi Golfer   :)


My ISP is actually... AOL 
Not... Talk Talk 

However!
As AOL is owned by Talk Talk - & - Uses the same Network as Talk Talk...
I've spent enough time reading the Talk Talk forum to know quite a bit about how things work.

First you need to know exactly what Talk Talk package you are on.
LLU - or - IPStream
UpTo 8mbps - or - UpTo 24mbps
Note: Talk Talk forum Staff... Will be able to tell you if you are unsure.

Your... Attenuation:  Down 47.0 up | Up = 28.5
So! - I'm afraid you're never going to get close to 24mbps  :no:


My... Attenuation:  Down 35.0 up | Up = 17.2
I'm on... UpTo 24mbps ( Noise Margin Profile = 6db )
My Sync Speed Today... Down 12073 | Up = 1020

(https://forum.kitz.co.uk/proxy.php?request=http%3A%2F%2Fwww.speedtest.net%2Fresult%2F904148553.png&hash=0491ed14a8982c27c6c5605040f14ac7429f01c7) (http://www.speedtest.net)

Sometimes I can get higher... Like... 9.50mbps



Now For... The Good News!


If you are LLU and on UpTo 8mbps... Talk Talk Essentials
Can't see any reason why the Talk Talk staff on the forum can't change you over to... UpTo 24mbps
As I believe all that is needed is the... Free Speed Boost  ;)
Note: You may be able to apply the speed boost yourself through your Talk Talk account.

Then....

You need to get a Talk Talk forum Staff Member to set your profile to.... 6db ( Interleaved )

This is the section you need to post in... Broadband Speed & Web Browsing: http://www.talktalkmembers.com/forums/forumdisplay.php?f=9


And here is some useful info about Talk Talk profiles: http://www.talktalkmembers.com/forums/showthread.php?t=15531

Note!

Whether OR Not... You end up on UpTo 24mbps
Having your profile set to... 9db - or - 6db .. Will certainly make a difference to your speeds  8)


Hope This Helps!

Zoe

Hi Golfer  :)



One More Thing....

Quote
My old line gave me about 6Mb speed.  My new line gives around 2.9Mb (it's an 'up to 8Mb' deal).  I assume the difference between the two is because I am now on a different exchange than before, further away than before and there is probably more traffic on the line.  What I would like to know, is there any way I can improve my line speed etc from my end, or is it entirely at the ISP's end?  Are there any tweaks I can make that would make a difference?  If it is the ISP, how would I go about getting a better profile/speed?



You Could Use....

SamKnows Exchange Checker: http://www.samknows.com/broadband/exchange_search
&
Talk Talk Exchange Status: http://www.talktalkmembers.com/content/view/109/149/

To see if your old ( Closer ) exchange is now Talk Talk - LLU
And how Full and Congested both your old and new exchanges are at the moment.

If So...
You could ask the Talk Talk forum Staff about the possibility of moving your connection back to the closer exchange  :-\

Because Your... Attenuation:  Down 47.0 up | Up = 28.5

You are not likely to see any significant difference to your speed.
8mps - or - 24mbps
It's a profile change to 6db that will be of most benefit to you.

However!
If you were connected to a closer Talk Talk LLU Exchange ...
Then you would have a lower Attenuation - & - Would see a much bigger speed difference on an UpTo 24mbps connection  ;)

Hi Zoe!

Many thanks for the in-depth reply, very informative and what I was looking for!  I can't be connected to my old exchange as I've moved area but the new exchange is LLU'd so I will request a re-profile as you outlined. 

I'm on TT Essentials up to 8Mb with Anytime Calls boost (40Gb limit - I don't get anywhere near this per month!) and on checking my account I see that the free speed boost is ticked but greyed out?  If I ask for a change to 24Mb, I assume this will mean an increase in costs?  TBH, around 8Mb would suit me fine as I don't go in for gaming or d/ling movies etc.

Thanks again - I'll post back soon and let you know how I get on.

Regards, Rich

You will only get the speed boost if your line can support it

As already pointed out it doesn't matter what package your isp does .......you will only be able to the speed your line will support.

So if you are able to get 5mb max,there isn't much point paying for a 24mb package.

Thanks - understood! As I said, the speed boost was already ticked on my account and I don't want to go for the 24Mb package anyway as my internet usage would not make it economical.  However, it appears that something might be done regarding the profile so I've posted on their forum and await the outcome!

Someone should be getting UpTo 24mbps .. Stuck at Only getting UpTo 8mbps.

Something very similar happened to me about 12 months ago.
I was still on AOL Upto 8mbps back then.
But one day noticed that I was suddenly only getting... 2mbps - to - 3mbps
No AOL Forum  :(
But thankfully when I phoned AOL... Was lucky enough to be put through to Ireland.
Nice man in Ireland recognised straight away that there was something wrong.
He Said.... " Put Down The Phone " - "Wait 5 Minutes " - " Reboot Your Router "

Was straight back to a sync of 8mbps - & - Speed test of approx 6.50mbpps.

Hi again Zoe!  Thank you for the time you are giving to this, it's all a bit 'new age' to me but I'm learning!!! 

I just checked my router config (HUAWEI EchoLife HG520b, standard TT issue router) and it lists current mode as ADSL2 under 'ADSL mode'.  There is a drop-down box where other modes are listed including ADSL2+ and ADSL2/2+(Annex M) so I assume it is compatible .  Do I need to reconfig the setting at my end to ADSL2+ and then reboot the router - OR, do I have to get TT's OCE's to do it at their end?

As I stated in my original post, the router worked 'straight out of the box' with no input from me so I left it at that - as I suspect a lot of people do - not realising there is a lot more one can do to improve speeds etc.

Re your link to TT's b/band advert - I had missed this completely about the 'up to 24MB' on Essentials (has this changed recently?) so for sure I will be posting the question on their forum as soon as I have done typing this!  (With ref to Uncle UB, and thank you - I need to check with TT that my line is capable of supporting such speeds)

Watch this space!

Regards, Rich

Title: Re: DNS servers

Hi Golfer  :)


It could be that you're exchange isn't yet capable of delivering ADSL2+  :-\
OR
It could be that you're exchange is delivering you with ADSL2+ .. But your router is only set to ADSL2 ( Which would knock you back down )

Really think you need to ask the Talk Talk forum Staff to clarify what you should be getting.

However!

Yep! .. You can change it yourself!
You could give it a go... See what happens  ;)
If it makes no difference or you're not happy... You can always change it back again.

Hi

As already stated with your attenuation you could expect to synch at around 5500Kbps ,BUT your Target SNR appears to be raised from the standard 6db. The reduction in synch rate can be as much as 1200Kbps per 3db above 6dbon your SNR margin.

quote (Did an exchange check too and it's ADSL2+ enabled).

That will give you some increase in synch rate  to about 6400Kbps as long as manage to negotiate the default 6db Target SNR.

That will give you some increase in synch rate  to about 6400Kbps as long as manage to negotiate the default 6db Target SNR.

Hi Jeff, thanks for the info!

I've posted on the TT forum and will await a reply from them.  I gather it takes a few days to be actioned but will post back here when I know what's what!

Update

Hi All!

My profile has been changed to 6db and the speed seems to have settled down at around 4Mb mark average.  However, the error stats have gone through the roof!

CRC  dn/up    54/655503
FEC  dn/up    15915/65519
HEC  dn/up    485/0

These are from yesterday (10th Aug) but stats from other days are just as wild!  Reading the help pages on here tells me that these figures mean throughput will most likely be affected, thus cutting the speed.  What do I do?  Will things settle down over time or do I need another adjustment by TT?

btw, SNR Margin is also all over the place - from beginning dn 10/13 up, then dn 5.9/7.7 up, dn 2.2/6.6 up, dn 3/10.7 up

Any advice, please?

Regards

Rich

I don't believe that those error stats are a problem. The reported upstream errors are probably reporting errors, not actual errors, and the downstream errors are not unreasonable. Just to check, is the CRC up figure correctly copied, or should it read 65503?

Oops!  Looks like I added an extra 5! 

On 7th Aug the figs read:
CRC d/u     37/65503             (as of 12.03pm 0/5 !)
FEC d/u     2782/65513
HEC d/u     625/0

Currently live stats are:
CRC d/u     389 / 65509
FEC d/u     6676 / 65451
HEC d/u     993 / 0

As I watch the router config page, these figures reset every 15secs or so and don't really seem to relate to the previous ones.  Reading the stats help page on here, it seems that this may be a sign of line instability and I might need to get the SNR Margin raised slightly to improve it?  (SNR stats have also varied - the default setting is 6db but this has reported as low as 2.2.)  I've re-posted some figures on the TT forum and am waiting for a reply.

I don't really understand too much of this so there is a bit of 'groping in the dark' going on!

Thanks for your help

Rich

It's probably true to say that a higher noise margin would give lower error rates, but your figures aren't really bad. The FEC errors are quite normal with an interleaved connection - they are actually errors which have been automatically corrected by the FEC process which is part of the interleaving setup.

The reason I queried the upstream CRC figure is because it's not uncommon to see figures in this range reported by some routers. The figures are suspiciously close to 65535, which is the largest value which can be held in a 16-bit number. I suspect that these figures are the result of a small programming error in the router firmware, possibly caused by mixing up signed and unsigned integers. It's most unlikely that you would really see upstream errors so much greater than the downstream errors.

Hi Rich  :)


Is Your Router.... Set To... Always ON  ?


Just Found This: http://www.talktalkmembers.com/forums/showthread.php?t=47886

Slightly different model number than your Huawei EchoLife HG520b

But...
As it sounded quite Complicated   ???

Quote
* To change the HG532 to always on (nailed up) you need to:
* open browswer and type 192.168.1.1 in the address bar, then press enter
* type "admin" for the username and password and press OK
* click on advanced in the left hand side menu
* click on OK to the advance user warning
* Click on "Basic" in the left hand side menu then WAN
* In the main window go down to "Dialling Method" and select "Auto" from the drop down menu
* Click the Submit button at the bottom of the screen to save settings.

Thought I should post it before I forgot where I found it  :blush:

Good evening Zoe and thank you!   ^-^

I've only just spotted your post as I've been merrily messing with my old Tiscali Siemens router.  TT forums pointed me in the right direction regarding setting it up and lo! I managed it  :) (Quite pleased with myself now!)  Oddly, it still shows Tiscali settings but only needed a username/password change to work!  I guess that as TT took over Tiscali the systems must be pretty much the same.

I will now monitor t'internet for a few days and see how I go.  Speed seems satisfactory at mo' and, more importantly, stable.

I can't thank you enough (and other contributors too!) for the time, effort and patience you have put into sorting me out.

All the best

Rich   :-*
