When they installed my new high speed modem (I signed up for 30 speed) I had troubles. After an hour on the phone with Telmex techies, they told me how to change the InfinitumB19E modem name to TELMEX. And it's worked fine. Now, a couple months later, I want to add a new computer and the WPA on the B19E modem doesn't work. I'm not sure if the techie gave me a new password at that time, but I can't add any other laptop to the TELMEX wi-fi. I've tried calling Telmex and they've disconnected from me FIVE times. Any other ideas? I have a new roomie who I can't connect to my internet. Thanks. Blue
