How do i setup router with ATT prepaid Card? How do i setup modem to see the sim card? Can't connect the modem to sim card so i can get onto the web.

How I set mine up was by following the tutorials right here on forum.

Thank You for sending these links but still no go can't connect to web at all see EM7455 but no internet at all. I really need a walk thru to setup router with ATT sim card and which protocol to used. All the videos on you tube show easy just plug your sim card in and you on the web. For example need to know which comm port to used. Which Protocol to used for example UMTS/GRPS?EV-DO i select this keep going in and out won't stay up.

em7455 (fw swi9x30c-2.24.05.06) ( awaiting usb adapter to update), ATT 3 month prepaid SIM, (sim works perfect in samsung phone).
Followed the great tutorials here, modem connects to att, get band 2, decent signal levels, 10.xxx IP etc,
NO Internet out to LAN ports. at!gstatus shows RRC = idle, never seen connected.
Ideas? Things to try?

RRC Idle means the network sees your device but will not accept it.
ATT is not being very friendly lately with all their plans and cellular modems. Try setting your TTL value to 65.
