Our main office ADSL connection has always been slow but seems to be getting
worse. We're with O2 which at one point got us up to the giddying heights of
~4Mbps but now we're struggling to get 2Mbps sync speed.
Looking at the router (Vigor 2830) we seem to be syncing at 1Mbps upstream
which seems odd if we can't get more than twice than downstream, unless I'm
interpreting the figures incorrectly:
ADSL Information ( ADSL Firmware Version: 232201_A)
ATM Statistics
TX Cells 38462411
RX Cells 211479088
TX CRC errs 0
RX CRC errs 71
ADSL Status
Mode ADSL2+(G.992.5)
State SHOWTIME
Up Speed 1012989
Down Speed 2032803
SNR Margin 10
Loop Att. 60
1012989 (~1Mbps) up is near the theoretical 1.4Mbps limit of G.992.5, compared
with 2032803 (~2Mbps) down being, er, nowhere near. of-course those are the
sync speeds not real world throughput. According to the router, the actual
throughput peaks are 383kbps up, 1804kbps down, which is the sort of ratio I
would expect, albeit that the downstream ought to be capable of more.
Any suggestions for improving things on the existing line by tweaking the
router config? I haven't tried speaking with O2 yet, figured that was unlikely
to get me anywhere unless I have good reason to believe I have a line fault.
