I have an SVi drop amp with 5-42MHz passive return. From everything I've read, this should work with my Rogers cable modem (it's a Motorola SB5100). However, while the modem can receive a signal, it doesn't send.
What am I doing wrong? Did I get the wrong drop amp?
Let me guess, you installed it right behind your modem despite the connection working fine because you thought you would magically increase your internet speed? You're overloading the tuner if this is the case (and it always is). Take the amp out before you damage your modem.
