What bands, modes, power levels?  Start with that, then as you make changes you can re-test and see if the susceptibility improves.

gut some computer power supplies for the ferrite toroids, and start winding the ethernet cables around them.  same for the power supply to the DSL modem.

winding the input line to the DSL modem is a little more problematic, as frequencies from the 100s KHz to a little into 2 MHz depending on technology are needed for the data signal.  best advice I can give you is to check in your modem for the uplink/downlink speeds and your WAN error count as a benchmark... and then wind turns of the cable on the toroid until you JUST start to drop speeds or grow noticeable additional errors.  that's as far as you can go without a noticeable loss of speed.

most DSL modem addresses are 192.168.0.1, type that in your browser and hit return to get into the modem menu.  don't go changing things, just watch... or you could whack yourself off the Internet.
