I am trying to change the max sync (download) speed in my VDSL connection on a BT HH5A with Openwrt18.06.8. I want to decrease a bit the max download speed (Data Rate) in favour of connection stability. I have spoken to my ISP and they do not decrease it for me, although I have proved that this is going to be beneficial in my case.
I have seen that Technicolor TG799VAC uses an openwrt variation and the following set of commands serves this purspose:
uci set xdsl.dsl0.maxaggrdatarate='300000'
uci set xdsl.dsl0.maxdsdatarate='250000'
uci set xdsl.dsl0.maxusdatarate='50000'
uci commit xdsl
However when trying to do this on my BT HH5A, I am getting "uci: entry not found". Is it because no such dsl profile currently exists or is it because the generic Openwrt version does not support such command (i.e. It is Technocolor specific)?
In the following forum, a guy has managed to do it on a Fritzbox7590 which uses Lantiq chipset too.
Finally, just to confirm, is this set of commands going to change the actual DSL sync speed (Data Rate in the DSL Status) or is it just a throughput limit imposed on the dsl0 interface?
