What speed NIC do you have in that 486?

10M? 100M? And is it running full duplex?

3.7M is, IIRC, about what I'd expect from 10M half-duplex. NIC cards of
that era were prone to getting auto-negotiation badly wrong.
Even an old 486 should be able to deal with 100M traffic easily.

Even so, I'd still not trust your cable provider's advice. There is
still a good chance the problem really is with the cable connection.
