Today I installed a new Hitron wireless modem to my system. I visited with a tech on the phone, but he could not get it to work. I have been working on it again this evening, eventually getting so it recognizes the modem. However, when I go to put in the network security key, it will not recognize the number. It said to type in the last 4 digits if the CM MAC number, which I did, but it still will not work. Can you help me? Thanks.
