BT home hub being slow

[Moscow Mule]

I have a BT home hub ADSL router thingie.

In the home page of said device, it tells me my broadband connection is

Broadband connection details:
Downstream 4,768 Kbps
Upstream 448 Kbps
Connection time 0 days, 0:23:47

However, if I do one of the online speed checker tests, I consistently get results of 1100(ish)kbps.

Nothing else in the house is using the internet at the moment - why is it so slow?

I've had problems over the last couple of weeks with BT, so has a couple of others here I believe. Is there something going on?

[original PM]

I have just moved 800 of my branches onto the BT network

so i may be nicking your bandwidth

Cheers!

Perhaps someone has installed another wifi network in the area that's causing interference - try alternating the channels used.

Wired connection. We use both normally, but for the test I plugged just one computer into the hub and switched off the WiFi.
