Infinity 2 - Sync Speed dropped

[jwynd]

Hi there all.

Over the past few weeks, I've noticed that my line speed (downstream) has dropped significantly from my usual ~55 Mbit.

According to the router, I've lost around 10 Mbit:

1. Product name:	BT Home Hub
2. Serial number:	+068343+NQ35114691
3. Firmware version:	Software version 4.7.5.1.83.8.236.1.2 (Type A) Last updated 12/07/17
4. Board version:	BT Hub 5A
5. DSL uptime:	0 days, 01:10:01
6. Data rate:	14993 / 45618
7. Maximum data rate:	16840 / 60345
8. Noise margin:	6.3 / 6.1
9. Line attenuation:	18.8 / 17.3
10. Signal attenuation:	18.6 / 17.3
11. Data sent/received:	66.5 MB / 512.7 MB
12. Broadband username:	bthomehub@btbroadband.com
13. BT Wi-fi:	No
14. 2.4 GHz Wireless network/SSID:	BTHub5-5TRT
15. 2.4 GHz Wireless connections:	Enabled (802.11 b/g/n (up to 144 Mb/s))
16. 2.4 GHz Wireless security:	WPA2
17. 2.4 GHz Wireless channel:	Automatic (Smart Wireless)
18. 5 GHz Wireless network/SSID:	BTHub5-5TRT
19. 5 GHz Wireless connections:	Enabled (802.11 a/n/ac (up to 1300 Mb/s))
20. 5 GHz Wireless security:	WPA2
21. 5 GHz Wireless channel:	Automatic (Smart Wireless)
22. Firewall:	Default
23. MAC Address:	34:8a:ae:76:d0:66
24. Modulation:	G.993.2 Annex B
25. Software variant:	AA
26. Boot loader:	1.0.0

This speed is confirmed on the BT Wholesale speed test:

Nothing has changed with my internal network setup to cause this drop. However, in the past I've had issues with the DSLAM, though I'm struggling to recall how this was resolved? I've logged the 'fault' with BT, however the helpdesk guys that I've spoken with so far suggest there is little that I\they can do...

My connection remains stable, however I'm currently wasting money on the Infinity 2 package and I really miss the extra speed that I've reliably had over the past few years.

Any advice appeciated on steps towards getting this resolved.

Many thanks.

the hh5 reset about 1 hr ago was that manual or hub dropping connection?  do you know if you hub has been dropping connection often recently?

try quiet line test  dial 17070 option 2  should be quiet and best with corded phone

have you tried using the test socket to see if that improves anything by eliminating your internal wiring as causing a problem

Hi @imjolly

Yes - the HH5 reset was in response to my call with BT (standard troubleshooting). I usually have a stable connection, often lasting more than 14 days without a dropped connection or reboot.

I haven't tried the Quiet Line Test or the test socket. Will give those a go tomorrow, though I'm skeptical. 

Here's the ADSLChecker results as requested:

Thanks in adv.

FYI, Quiet Line Test appears fine. Can't hear any static or noise. Haven't had a chance to look at the test socket yet.

Hi there. Still get the same sync speed on the test socket it seems. Any other advice on next steps? I think I've ruled out this issue being internal to my network.

if you are nowconencted to test socket with a filter can you repost router stats for comparison

FYI, this was finally resolved by an engineer visit. Line was 'reset' and moved from 'interleaving' to 'fast'.
