ADSL2+ broadband speed variable

[#1]

Any chance someone can check my broadband settings?
Should have the upload speed uncapped but it seems to be limited lately.
Download speeds are pretty much as usual (8M to 9M) but uploads are down from 0.7M to around 0.4M
Many thanks.

Hi cjags,
I've just checked your line and can see that the upload is showing as uncapped.
Did you achieve these speeds over WiFi or ethernet?

Ethernet.
Modem is connected directly to ADSL faceplate.

OK, I can't imagine what else you could try to eliminate this as being a local issue so I'd raise a fault if that continues to be an issue:
