Latency Type & Changing it

Hi all...
Just a quick question about interleaving & FastPath, or whatever it's called.
When I first took out my option 3 broadband, I was getting a stable 6.5-7mb -- actually what I was told I'd get when I signed up, which is obviously great -- however two or three weeks later I've been getting a lot of disconnections in online games and ping-spikes.
I've looked around various forums and this one and read a few of other peoples' problems and the suggestions -- off the top of my head; disabling 'N' wireless function, changing channel pref. 11-13, make sure FON is disabled, change to WEP from WPA2, and the list goes on -- but haven't really got anywhere. However, I've just stumbled across a thread on Hexus.net, a hardware/computing review-type-site, about FastPath and how it could decrease latency due to certain error checking being disabled and that, should you wish to have interleaving disabled and, thus, it enabled, phone BT...
Line stats according to my HH2 Type-A:
Ignore the connection time, was testing channel 12 and it seems my NIC doesn't like it so had to reset to defaults Prior to that, my line had been up for over 2 days... Any way, am I right in thinking that interleaving is indeed disabled on my line? If so, is it just a matter of phoning BT and asking them to re-enable and in however many days it'll take, it'll be back to 'normal'...? Thing is, I didn't ask for it to be changed in the first place and oh, before I forget, on a side note, FON seems to randomly enable itself, or at least has twice since I've had this broadband; not sure how it disabled the first time but it was on prior to my reset-to-defaults earlier this evening...
Just for kicks:
Download speedachieved during the test was - 2954 Kbps
For your connection, the acceptable range of speeds is 600-7150 Kbps.
Additional Information:
Your DSL Connection Rate :8128 Kbps(DOWN-STREAM), 448 Kbps(UP-STREAM)
IP Profile for your line is - 7150 Kbps
Cheers all
EDIT: Only noticed a real problem since last Sunday where my HH updated it's firmware, though, looking at the HH pages now, it seems to have updated again today

Well, it might be wise of me to leave it a few days to see if how it is now (yeah off peak & all) continues... That would be nice... Otherwise, I'll cry for a mod to come along
Hope you get your way... They can't refuse to disable it, surely?
EDIT: Just for fun, as it's off peak, I thought I'd get something to compare the above result with -- gg, BT... gg:

Latency type changed back to Fast path

I recently had my latency type changed back to interleaving however i now get daily disconnections (usualy when recieving a phone call) and my download speed isnt any better, the only difference is an increased latency of around 10-20ms so i would like to have it reverted back to fast path.
Thanks, Rob.

Latency type changed from fast to interleaved

My Latency type as changed from Fast to Interleaved, why?
From - Latency type: Fast
To - Latency type: Interleaved
Can it be changed back to fast ?
Since it as changed, it feels like my broadband is now being capped. It as become slow .5mb when usually I was getting 1.9mb.

Changing latency type to fastpath

I would like to have my latency type changed from interleaving to fastpath I have asked previously via live chat and they didnt end up changing it for me, thanks.

You would need to provide connection information here, and get advice from forum members before anything could be done.

Which latency type

Hi,
apologies if the following query is a dumb one, but I am ignorant when it comes to this stuff
our broadband is used by one pc hard connected to the home hub and 2 laptops wirelessly. The pc is used for warcraft and the laptops for bbc iplayer streams etc.
My question is, would having my latency type changed to fast from interleaved enhance/improve the performance of the pc/laptops when gaming and or streaming?

No, changing the latency to fast could introduce a lot of CRC errors, which would slow your connection down.
You need to avoid all wireless connections if you want good streaming performance.

Slow Speed after Latency type has been changed

Hi,
the last few days I have noticed that my broadband speed has gone down hill big time.. according to speedtester.bt.com my DSL connection rate is: 20504kbps (down-stream) and my IP Profile is 18090kbps, but my download speed is 2411kbps which is below the acceptable range for my connection.
I logged onto my BTHH3 and found that my latency type has changed from Interleaved to Fast, I have noticed that my CRC & HEC (down) are much higher than before..
Should I leave it for a few days to see improvment or ask the mods to change the latency type back to Interleaved
Thanks in Advance

I also re-installed my BT HH2 and that connects using Interleaved as to Fast via BT HH3, while my HH2 is connected I get 15.82mbps via speedtest.net but I keep losing my connection - don't think my HH2 likes 3.7 dB (down) noise margin.. but if I re-connect my HH3 I have a steady connection but 1.6 to 2.2mbps via speedtest.net
I think its time to get a new non-bt router/modem....?

BT Infinity - Changing Latency type

Hello!
I have read a few articles that say that you cant change your latency type from Interleaved to Fast Path with BT Infinity because the modem is in a little white box and not part of the HH.
This is only the case for some people though. I still connect with the telephone wire and not the WAN port. I have always had a brilliant connection (noise wise etc.) and have always hit the theoretic max of my broadband on ADSL2 and now VDSL.
Would I be able to request my latency type be changed to Fast Path (as I assume it isn't that, although you can't tell with modern HH's) as I do not have this seperate modem box?
Thanks,
Craig

That's right, you can't. DLM handles the transition automatically.

I'd like to change my latency type from Interleavi...

I would like to change my latency type from Interleaving to Fast. How would I go about doing so/who do I contact.
I have checked previous threads, but old links on such threads do not work anymore.
Solved!
Go to Solution.

Thanks for the quick reply. Things make more sense now. I read up about the DLM and yes apprently it must have changed it over around the time I had a lot of visitors with their laptops and what not. This is just an educated guess here but a lot of resetting of the router went on during their visits, at least once or twice a day for a while now and it's possible THAT is what made the change of the latency setting.
It may be fine if I just advise everyone to not touch it at all and it will change back in a period of time. But just to check because I do know myself that the line and connection was pretty stable even before all this, with a lot better latency (which is what I want the most). Is it possible to force change it back? Thank you.

Want to change latency type on my line

Last year I had a new line laid into my home after 3 years of problems with the old one. Earlier this year I opted for the upto 20 Meg speed, my line is outputting around 18.6 which is fine however recently i've been experiencing disruption to my line.
Sometimes the Hub will reset itself, then when it comes on the broadband light flashes yellow for ages whilst the other lights are blue sometimes upto 5 mins will go by, requiring me to reset it manually to achieve a stable blue light & connection.
I've checked my latency type and found its interleaved. My old line was Fast type as I a game alot and I need a fast stable connection. I think it must have been an oversight when they connected my new line at the exchange they forgot to use the same settings, I do have an I-plate installed so its not an interference thing either.
Is there anyway I can get my Latency set to Fast type please?. My download speeds are stable although sometimes erratic so its not a line problem I have just an exchange setting.

Right, then clearly theres something not quite right with my line then, shouldn't be taking ages to re-sync after a reset. Is fast latency still better for gamers though?
Depends on your definition of "better for gamers".....
You either have an interleaved connection that affords stability, maintained IP profile, and maximum sync rate, with maybe the addition of roughly 20-40 milliseconds latency to server connections, as a worst case scenario.
Or you have a slightly lower latency connection, with no forward error correction, possible rise in noise margin, resulting in lower sync speeds and associated IP profile and throughput.
A no brainer really .... over to you.
