grrr pipex!!!!!

PrivatePyle · Post by **PrivatePyle** » Fri Oct 12, 2007 12:55 am

I recently upgraded my service from 2mb to 8mb max, on the day it was meant to upgrade, I rebooted router, no speed change, so tried every hour or two for next day, still no change.

Rang pipex up, and got through to 2nd line support, he told me it was a BT problem and would be fixed by next day as BT were not allowing me more than 2, next day, still no change.

Next day I rang pipex up, another 2nd line support guy told me I'm syncing at 8meg, so the reason I'm still getting only 2meg speed results is because of something he describes as fluctuation where your exchange works out best speed for you over a ten day period. Then said "if its not sorted in ten days ring back".

Now I think he is telling me story just to get rid of me, I told him about 5 times that my speeds are not fluctuating, and that everytime I reset router and do a speed test its consistently around the 1930kbps mark (what it was before my supposed upgrade), I even asked him for his definition of fluctuation as to me it does not mean a very stable result consistently for 3 days running.

Being told to ring back in ten days really made me quite mad, can anyone here who knows abit more about ADSL confirm that the fluctuation theory of theres does indeed sound like bull?

Then select "Apply Changes" and reboot to take effect

Are you using a router? If so, log into your router and ensure MTU and MRU is set to 1492 (and MSS to 1452 if any) and save and reboot the router to take effect. After that, try the first TCP Optimizer settings again to see if MTU becomes 1492.

Yes, using a zoom 5560a router.

edit : mtu on there is defaulted to 1500 as I remember.

Ok, I shall try those things.

Ok, this is before doing those suggestions to router, with the last settings you gave me.

Good. TCP Window follows the Analyzer's recommendation.

This is after setting mtu to 1492 on router, no sign of mss setting, and no mention of it in routers manual.

MTU is lowered to 1452 and so TCP Window should follow at 259808.

My guess is that you have to update the firmware of your router to achieve MTU at 1492. Try searching Google for the latest version number.

Check the line speeds at the ADSL status in your router.

Your ISP has not yet upgraded your line speed to 8 mbps. You should take note of the day the higher speed is activated and be billed for the speed starting on that date.

Your TCP Window has been raised to handle 8 mbps.

PrivatePyle · Post by **PrivatePyle** » Fri Oct 12, 2007 2:24 am

Adsl status page says -

Downstream Speed 8128 Kbps
Upstream Speed 448 Kbps

But I'm guessing thats not my actual speed, but what my line/exchange should be able to handle.

Phoned them up saying this, reply "blah blah blah mr clift, ten day stablisation period, you are now on the 8meg max package."

1 week one from supposedly being activated, still no change, bugger!

PrivatePyle · Post by **PrivatePyle** » Sat Oct 20, 2007 3:16 am

Well my ten days is up, and my bt speed tester results are still

IP profile for your line is - 2000 kbps
DSL connection rate: 448 kbps(UP-STREAM) 7680 kbps(DOWN-STREAM)
Actual IP throughput achieved during the test was - 1807 kbps

I've spent the last 5 days telling them this means I have a stuck bRAS profile at 2meg, and they said they wont do anything till after the ten days is finished.

When I phone today, if they suggest I spend another few days doing more speed tests, I'm going to unleash ten days worth of frustration at being lied to, as I've been telling them what the problem is already.
