Yeah I probably installed the old modem with a CD. It was 4 or so years old maybe?

Hi
You have changed routers  yes ?. The stats display is different.
If that is the case then you are being Capped by your ISP.

I have emailed Vispa asking why my line has been capped and sent them the above data. Hopefully they will reply soon enough. :)

Okay Vispa got back to me. That was quick.

They say BT capped my line at 6mb as it kept dropping. Probably cause i kept turning off the modem.

They have asked BT to reset my line. Will take 24 hours.  8)

I will be back in 24 hours with some line stats once they get it sorted.

Finally getting somewhere. :)

Excellent news.

Thats the fun bit for the ISP ;).  I did mention in one of my earlier posts that I suspect that it may be the 'silent' DLM cap because  6656 does seem to be a common figure set by the DLM, if it thinks a line is unstable.

Sometimes even the ISP isnt immediately aware that the line has been capped and a while they used to have real fun trying to convince BTw to reset the line.  Supplying your linestats to the ISP and stating that you now have a new router helps convince them that you kinda know whats going on.

My memory is rusty, and I'm sure someone will correct me if Im wrong/out of date, but the automated/queued resets generally tend to occur during the wee small hours.  So hopefully either tomorrow morning or the day after your line will resync at a much higher rate.

You may incur a bit of instability over the next few days, as your connection settles into the new best rate for your line.   I would leave the router connected during this period....  unless theres an obvious problem from the stats, and we will advise you the best time of day to reboot.

>>> Rate (Kbps):   16651

Yay... much better :)

>>> Rate (Kbps):    443

hmmmmmm  upstream cap not lifted? 


>>> speedtest online still has me at 4mb or so still.

Could either be:-

1) ISP not yet advised by BTw of new speed and they need to adjust their figures accordingly.  ISP's are advised in batches daily so could be tomorrow before any ISP profiling is lifted.

2) New bRAS not yet updated.

 Have just asked my ISP those very 2 questions by email. I wonder if they have found this post yet. Most ISPs browse forums like this. ;)

On a side thought would firefox continually not responding lately be due to my broadband or poor browsing software?? Hmmm.

Vispa is well aware of this site.. in fact they lifted a lot of my pages for their own knowledge base.

>> would firefox continually not responding lately be due to my broadband or poor browsing software??

TBH Ive found that FF is often clunky and slow and Ive been turning to chrome, which is a lot quicker.
However it could be your line..  again your linestats can tell us a lot about this..  we'd be looking at the type of errors reported from your router over a period of time.

I've had good results for my customers who use FF with SpeedyFox: http://www.crystalidea.com/speedyfox

The continual firefox not responding but recovering a few mins later has only started in last month or so? I have never really tried Chrome. I just removed all the google stuff from my pc and now you suggest i re add it.  :wall: :wall:

Let's see how my line stats settle over the next few days. I am leaving the modem  on 24/7 now.

Do you think this line would hold an infinity service?? Would it truly reach 40mb speeds?? I am jumping the gun a bit. They have delayed my FTC date to December 31st 2011.

Do you know why Plusnet can install FTC services so cheaply?? It seems companies not owned by BT charge nearly £100 just to install it.  :ouch:
Vispa are suggesting this is what BT Openreach charge circa £79+vat.

I think for now let's wait and see what speed this line settles at. :)

It's an 18-month contract, so the startup costs are spread over that period.

Okay Vispa have got back to me again. Their customer service is so quick!! Under 30-40 mins maybe??

Quote vispa email in bold.
BT wholesale do not advise us when the reset completes, nor do they advise us what the speed will be once completed, however, upon checking it just, it appears that the increase has completed. As you can see from your router stats (and I have confirmed this on BT systems) your downstream speed is now 16650 Kbps (16.5 Mbps)

When you ask 'have you adjusted your ISP settings accordingly', can you please elaborate on what you mean by 'ISP settings'?


Also, your upload is capped as you are on a residential product, if you would like a higher upload speed then you can choose one of our business packages which will remove the upload speed cap.


All fair enough really.

I did a speed test on the BT site and got these results around 21.15hrs today.  I need to do 2 more tests at different times. What is a good speed for a 20mb service??? I guess no one truly gets 20mb speeds.

 Download speedachieved during the test was - 7424 Kbps
 For your connection, the acceptable range of speeds is 4000-21000 Kbps.
 Additional Information:
 Your DSL Connection Rate :16650 Kbps(DOWN-STREAM), 443 Kbps(UP-STREAM)
 IP Profile for your line is - 14690 Kbps

2. Upstream Test: -provides background information.

   Upload Speed
   361 Kbps
    
0 Kbps   443 Kbps
Max Achievable Speed

>Upload speed achieved during the test was - 361 Kbps
 Additional Information:
 Upstream Rate IP profile on your line is - 443 Kbps
