Hi @toonlass Thanks for taking my call earlier and good to hear that the connection has now been very stable for the last few weeks and we can close the fault. If the problem comes back do let us know and we will be happy to help.

Hello

Thank you so much for your help - i really thought we had got somewhere.  Unfortunately after 2/3 weeks of consistent good speeds (3.3mbps) and closing the fault with you thursday we have again had the return of low speeds for no apparent reason.

This is the router stats (wired):

System Up Time 557:26:07

ADSL Link Downstream Upstream Link Rate 4256 Kbps 448 Kbps Line Attenuation 45.0 dB 31.0 dB Noise Margin 6.1 dB 19.0 dB

The BT wholesale test (wired) tells me:

Download speedachieved during the test was - 1.15 Mbps
 For your connection, the acceptable range of speeds is 0.6 Mbps-7.15 Mbps.
 Additional Information:
 Your DSL Connection Rate :4.26 Mbps(DOWN-STREAM), 0.45 Mbps(UP-STREAM)
 IP Profile for your line is - 3.5 Mbps

No faults are reported in our area.  Quiet line test is quiet!

Any further help would be appreciated!

Wired or wireless?

The OP posted the speedtest is wired

[RogerB]

It's a possibility some VLANs have been under pressure last 2-3 days, what with Youtube streaming Crufts etc. ... or maybe on a congested VLAN anyways, normally. If it gets better after Sunday, you'll know. If not, back to the drawing board and moderator assistance with BTw.

Are you in the test socket with the hub/modem?

[toonlass]

Yes I am using the test socket when posting the stats
