They could if they agreed so. Indeed ADSL2+ will downgrade to ADSL if it finds line unstable.
But you might be able to do it yourself via the router. You certainly can with the DG834G v4 (Broadcom chipset), but I don't know the DG834G v5 (Conexant chipset).
Look under the Basic or ADSL Settings for an ADSL Mode field. Failing that you may be able to get at it via TELNET as per this page:
http://www.kitz.co.uk/routers/netgeardg834_interleav... . I don't know the BusyBox command for the V5 but for the V4 it is
'
adslctl configure --mod d (or it might be
1)'.
Or try '
adsl help'.
But post your router stats (Show Stats) anyway; we may be able to see something.
