Problems after upgrade to BT Business Total Broadband Option 2 ADSL2 Next Gen (prt2)

[ciaran77]

I've had to restart my post as someone has locked my original post? See same topic for the background.

Well today my problems have reoccured. I had this on my router today.

Status:	Up
Downstream Rate:	1231 Kbps
Upstream Rate:	696 Kbps

After several router restarts, because it just wouldn't get anything better than a 1.2mb circuit, I finally managed to get a 16.9mb connection, but downloads are slow again, just 7mb. I have been getting 13.6mbps downloads for 3-4 weeks solidly, and then this.

This seems to indicate a pattern, every now and again my service just drops. My sense is there is an issue at the local exchange (it took a major incident there last time to finally get decent speeds after weeks of wasting time trying things at my end) after the incident my line was stable and I got decent speeds for 3-4 weeks.  Ping tests now show 13ms responses, so I would expect download speeds to be at least 13-14mbps. But I'm only getting 7mbps.

 Download speedachieved during the test was - 7693 Kbps
 For your connection, the acceptable range of speedsis 2000-7150 Kbps.
 Additional Information:
 Your DSL Connection Rate :16946 Kbps(DOWN-STREAM), 1211 Kbps(UP-STREAM)
 IP Profile for your line is - 8000 Kbps
The throughput of Best Efforts (BE) classes achieved during the test is - 4.71:18.45:76.84 (SBE:NBE:PBE)
These figures represent the ratio while sententiously passing Sub BE, Normal BE and Priority BE marked traffic.

The results of this test will vary depending on the way your ISP has decided to use these traffic classes.

Could BT advise on next steps, I firmly believe there are no issues at my end, there's lots of background info in my previous post and logged from my many hours of phone calls since December. I'm puzzeled as to why my ip profile change every 3-4 weeks, when my connection rate is consistant at 16.9kbps?

thanks.

No call so far from TO, so I called sales, explained the problem, and they are sending out a Business Hub for free as I declined it several years ago as I have my own router.

[ciaran77]

Just had the call from TO, they agreed there is an issue somewhere, I should be getting about 16mb, so we will replace the router first and they will reset my profile at the same time, monitor that, and if no different, then request a lift and shift at the exchange.

[ciaran77]

I replaced my own router with a BT business hub yesterday, TO advised to monitor for a day to see if the router connects at a higher speed, so far there is no change.

Is there anything in the stats below to suggest why I am not getting a 17mb connection?

FAO Fiona,

I just can't believe how frustrating it is to deal with BT Business support on this issue.

I called TO to ask for an update on what is happening as my speed is getting progressively slower, evidence above, they advised they need to dispatch an engineer to me, nothing confirmed so far, they would get back to me.  This is the third visit, and I've also had 2 no shows as well, tech support messed up the booking twice before. I explained again I had a visit last week, what triggered that visit (speed dropped to 2mb) and what happened during the visit, and the reason they are now involved is that he found no issue from my side.

Just to recap, I had an engineer visit last week for 1.5 hours, no issues found, he rewired to my premises, replaced the MTU+filer, to eliminate those, rans tests before and after the changes, and I replaced my router with a BT Business hub.

I don't know what else to say.

Hi ciaran77,

I sent the agent involved in your case all the information from the post yesterday and also your notes above, he will be in contact with you to discuss.

Kind Regards

After a router reboot advised by TO, I now have an 18mb connection, a 15mb ip profile and 14.5 downloads. Only time will tell if this remains consistant......

Seems that for some of us, the technology does not work as advertised and after issues on the line which cause the profile to drop, it is not able to go back up after a period of stability, and even though my profile has been raised at the BT end, my end still saw an 8mb cap on the line. Only a hard reboot of the router at my end allowed the new profile to work.

More updates next week.......
