Problems with BT Broadband speed using a HomeHub

Hits 14020 | Created 2009-03-04 | Modified 2009-03-05

My speed started to drop and eventually became tediously slow. From multi-megabyte to around 200k or less speed. This is a log of what I did to try and resolve the problem.



1. Restart the hub. Go to http://bthomehub.home/ then 'Settings', 'Advanced Settings', 'System', then 'Restart'

2. Okay, I assume you've restarted your PC? Uninstalled any curious programs you have installed just before the speed drop? Done a comprehensive virus scan and trojan/bot check? I recommend AVG Free and SpyBot Search & Destroy (do a Google Search)

3. Go to http://www.speedtester.bt.com/ in Internet Explorer (it often crashes in FF) and follow the instructions. You will eventually get a results list like this:

This Test comprises of two tests

1. Best Effort Test: -provides background information.
Your DSL connection rate: 8128 kbps(DOWN-STREAM), 448 kbps(UP-STREAM)
IP profile for your line is - 7150 kbps
Actual IP throughput achieved during the test was - 210 kbps <<- This is too low!
2. Assured Rate Test: -provides background information.
Assured Rate IP profile on your line is - 600 kbps
Actual IP throughput achieved during the test was - 266 kbps

This test was not conclusive and further testing is required.


The important figures here are the DOWN-STREAM and first throughput figure.

Your DOWN-STREAM figure should match the best speed in your area, the speed you are supposed to connect at if you connect at the maxiumum.

Your throughput is the actual speed that is being seen at the moment, on average. This will likely be nowhere near as high as they maximum speed, but as a guide it should fall in these ranges (very vague table):

DOWN-STREAM | Throughput
0 - 300 kbps | 50-300 kbps
300 kbps - 500 kbps | 50-500 kbps
500 kbps - 1000 kbps | 100-1000 kbps
1000 kbps - 2500 kbps | 200-2500 kbps
2500 kbps - 8000 kbps | 400-8000 kbps


If your down-stream figure or throughput are well below the expected range, then you should contact BT Broadband Support and get them to check your line.

Note that throughput speed will change, and at busy periods will be slower than at quiet periods. Ideally, run two speed tests, one at peak times (5pm-10pm) and one outside of this period.

Contact the BT Broadband technical helpdesk on 0800 111 4567 (open 24 hrs).

4. Swap micro-filters around. These do go wrong.

5. Try a different router. This was suggested to me by BT. I don't have a spare router, I explained.

6. Are you plugged into a phone extension? Try plugging your connection into the main one. Likewise, try to reduce your cable length.

7. Are you connecting via wi-fi or network cable? Try a direct connection to the home hub, they problem might be wireless.

8. Does your phone socket look like this? http://www.webuser.co.uk/specials/197121.html Okay, try what he says.

9. Try a line check with BT

10. Try BT's troubleshooting list

11. Download and run 'SG TCP Optimizer' http://www.speedguide.net/downloads.php - this worked for me! Speeds jumped up to 6,700 kb/s after a reboot!?!

I tested my broadband speed test using the http://www.ip-details.com/ .My speed test result,
