Old speed problem returned due to bt line problems

hi, hope someone can help, i went through weeks of agony probably a couple of years ago now getting my sync speed  and line speed up to 7-8 mb after changing my cables and bt master socket and getting some very good support from plus net forum staff, which improved my online gaming no end, and my speed tests used to run at approx 6.7mb on plus net tester
i have recently had a problem with my phone line with which meant everytime i picked up the phone i got a loud screeching and i could also hear and talk to two old ladies talking on the phone.
i have checked my plusnet connection setting and carried out a bt test and my line profile is down at 5000k
i have posted the result below.
what should i do to get it back up as my games are lagging and i pay for the  premium gaming connection.
many thanks
Andy

Re: Old speed problem returned due to bt line problems

Screeching: unless you have a dodgy cordless phone, surely that's open-and-shut BT line problems (i.e. not your wiring)?  Has it completely gone?
Gaming lag: 5000kbps is massively more than any game I've ever played would need, so your IP profile is not your lag problem (despite limiting your download speed).
Are your pings OK (i.e. small and stable)?

Re: Old speed problem returned due to bt line problems

hi, thanks fopr the quick reply, the bt fault has been repaired and i can now use my phone, but i have noitced the line speed has dropped, its not only the gaming which is battlefield 2 but generally when you get used to nearly 7 mb and then get 4, you notice the difference, but my point is, it was 7mb at its best and is now testing at around 4mb sp somethings wrong.
i just rang bt to ask them and straight away they said they would send out an engineer!!
many thanks

Re: Old speed problem returned due to bt line problems

Glad your line's fixed Smiley
As for the gaming, lag is all about latency rather than throughput.
I'm tempted to imagine that ping time is a function of sync speed, not IP profile (but I'm guessing there).
Your actual ping times are the key here though.  Do you know what your current (and previous) pings to the game server were like?
EDIT: forgot to add that IP profiles recover automagically - how long has it been since the line fix?

From those figures you don't currently have a problem. What's happened is that during your phone problems your ADSL line has synched below your normal speed and your profile has been reduced. Now your line problems have been fixed your synch is back up to 8128k ( the maximum) and your profile will eventually recover. But its going to take a few days for this to happen. That's how the DLM ( Dynamic Line Management )  works I'm afraid... Sad

Re: Old speed problem returned due to bt line problems

thanks guys, i hought that would be the case, it was only fixed today, so i checked the speed and it was down, when i first tried to get my speed up to the 8mb connection it took weeks of fluffling around
i think i will leave it connected and see how it goes over the next few days

Re: Old speed problem returned due to bt line problems

Leave your modem/router on 24/7 will be the quickest way to get your profile back up.
The check you don't have a latency issue do a few ping tests from a cmd prompt. Try ping bbc.co.uk and ping plus.net (without the www). Post the results.
Edit: Latency is not related to sync or profile, it's purely interleaving off/on (off for shortest times) and distance from the gateway.

Re: Old speed problem returned due to bt line problems

Those low ping times clearly show you are on fastpath (interleaving off) so no problems there. If your profile has now recovered, also check at the member centre https://portal.plus.net/my.html?action=data_transfer_speed , and if throughput speed has returned to normal levels but you still ahve a problem, then it may be game specific. If so, then the best thing may be to start a specific thread on the Gamers Forum.

Re: Old speed problem returned due to bt line problems

FYI, I just did a few quick calcs to see how much (or little!) the sync speed ought to affect the ping times Smiley
Your 448kbps upstream speed means that the minimum possible time for the actual uploading of the ICMP ping packets is somewhere in the ballpark of 1.2ms (assuming no interleaving and also ignoring the details of the PPPoA stuff cos I'm very hazy about them!).
Then at slowish downstream sync speeds - let's say a dismal 1152kbps (like me Smiley) - the return path would take something like 0.5ms.
Speeding up the downstream sync to your depressingly high 8128kbps would take that return path down to well under 0.1ms.
So that'd mean that losing downstream sync speed really badly (to 1Mb levels) would add less than 0.5ms to your ping times.
(i.e. Chris was right Smiley)

Re: Old speed problem returned due to bt line problems

sounds good to me, no change yet but its not 3 days,i have a feeling i had to ask for it to be changed last time but we will see, i do pay for the gaimg specific connection but i have never been sure what that actually does
thanks for the replies, and sorry to moan about the speed, but when you have had it high, it becomes a bit obsessive to get it back there.
i know BF2 is a real hungry game for resource with loads of differnt players all interacting together like 6 people all in one helicopter and if you are a bit slower they dont like it cos it causes lag in the game and you also miss targets when shooting
i am still a kid

Re: Old speed problem returned due to bt line problems

Re: Old speed problem returned due to bt line problems

Hi Martin,
Please leave your router turned on Smiley
You've got a good connection speed so BT should amend your profile soon.
Then your speeds will be back to normal.
