I just started a similar thread
since I couldn't search for this one... Haha... how ironic. I should have paged farther into the forum.
Any of the OPs here answer the original inquiry as to what modems are compatible? ADSL equipment is pretty rare in the market these days, other than stuff you find on eBay and such.
I am on Fusion X1 for now, but would like to go to X2 if I can locate a compatible modem. I do not wish to rent a Sonic-provided modem. $10/month adds up fast over the years.
Any existing customers, or Sonic Support, what is the rental make/model of modem/router in use?
