Router fault has caused DLM to reduce line speed by 50%. How can I get this reset quickly?

I'm honestly not sure how else to explain the real world drop from 50mbit to 25mbit. This is over an ethernet cable plugged directly into the router. This is also a real world figure that's significantly higher than the router reported line speed. 

The only other explanation as far as I can tell is that this router is just delivering a much lower speed. But it's rated for 1gbit and is a fairly high end tp-link router. Unless I've somehow configured the router wrong in a way that would somehow limit speed I'm not sure what else to look into?

Have you still got a BT hub you could connect to see what sync speed that gives?

[Tiyuri]

Sadly not, I actually usually entirely rely on nest wifi throughout my home and my BT home hub died a long time ago so I just replaced the router and moved on.

I'm only currently connected to the router because of this speed issue. Generally the router is just a modem that supplies connection to nest wifi.

All I can suggest is see if you can borrow a BT hub or other router to try. If what the router is reporting is accurate, a DLM reset will do nothing.

I'll see if I can find one somewhere I suppose! I appreciate all of the help.

Does anything here look wrong:

[licquorice]

You could try setting DSL Annex type to Annex B to see if that makes any difference.

[Tiyuri]

Sadly only Annex A is available in VDSL mode.

[licquorice]

Annex A is correct anyway, just something to try.
