Those stats are seriously wrong. At the moment the modem is syncing at 239kbps download and 440kbs upload with SNR margin of 36.5 down and 18 up.

The margin indicates how much "buffer" there is in speeds, or how much extra speed the line is capable of (which can be sacrificed in exchange for stability). Typically the margins are between 3 and 12 in both directions, a margin of 36.5 means the modem is failing to realize the vast majority of the speed the line is capable of.

The downstream output power (if correct) is also way too low, and should be in the 15-20 range.

In any case yes, there's a severe fault somewhere, which could be a bad line, bad modem, or bad exchange equipment. More likely a bad modem, or secondly line but anything's possible. You'll need to phone the provider and get them to check things, that line should be doing at least 15-20mbps, not 0.1mbps.
