Try *type* of cable instead ?
Is the cable cat5 ? cat5e ? or cat6 ?
I laid around 600m of cat5e in my house which is good enough for around 300mbs and I get wonderful pings between equipment pity I didnt lay cat6
silly me nevermind next house maybe...
with cat5e here are my pings :
pinging the cable modem
(bedroom 2 -> node 0 (10m) -> bedroom 1 (10m) -> router -> back to node 0 and the cablemodem (10m dowstairs) = around at least 30m of cable

Pinging the router

Pinging the cable modem directly from the router around 10m of cable
These pings look high but they have always been that way no matter what length of cable (cr8ppy cable modem me thinks)
