I just upgraded to this combo modem/router from sympatico couple days ago. The first problem im having is that there is no way to chnge the MTU, it's set at 1500 which is not what I want, 1492 is ideal for my setup. Heres the S#!tty part of the deal,  Sympatico only supports the set-up and instalation, meaning they only care about getting you a connection.  I called  the company who makes the modem/router for support and they wanted to CHARGE me dollars for their help.  BullS#!t, I should have kept my old set-up.  If anybody knows how to change the MTU please let me know. Thanx
