> I'll check out Electra Health and the shield cable and ground adaptor.

Unfortunately, I once tried those products from Electra Health, and felt they made my situation worse, not better.  In terms of symptoms while using the computer, that is.  So I reverted back to my unshielded / ungrounded setup. Less symptoms that way.  

But it's worth a try... but just like every suggestion here, it may or may not work out.

The biggest reduction of symptoms I had from the internet connection included doing the following totally different things:
 
   -- switching from DSL to cable internet
   -- comparing various cable internet modems until I found one that bothered me the least
   -- comparing various routers until I found one that bothered me the least
   -- install a ground loop isolator on the incoming coax cable to the modem
      (for some reason that coax cable was causing a ground loop)
   -- install a coax cable signal attenuator on the outside of the house (to knock down the excess signal
       levels that I didn't need to make the modem and cable box work)
