Yes, it could be that simple.

You also want to look for bad DSL filters.
A lightning strike can leave one damaged, but still working enough that the phone seams to work fine, but it is messing up the DSL link.

Having a filter before all the non DSL wiring in the house will help the S/N ratio too.
All the non DSL wires that the DSL signal is not diverted down, will mean more signal gets to the modem.

The way I have it at my house, I have the DSL/phone splitter right in the service box.
The phone side goes to all the house wiring.
The DSL side goes on an unbroken cable all the way to the DSL modem. That saved a good 10 db of S/N link margin.
