I have used Netgear dg834gt for the last few years and i was very happy with it.Now i has packed up i i need a replacement.The problem is that all new netgear modems have a built in antenas in it and my old dg834gt had an antena that i could unscrew and i have replaced it with with external 12 db antenna that gave me an extra range(and i really need that).The model since than has been discontinued.Can anyone suggest a modem that is on the market that has an option of replacing an antenna on it?Thank you.
