Hello! I have (2) brand new Sierra Wireless MC7750 LTE 4G modems (Verizon network) that Heartland just shipped over to me. I have (2) CF-19RHRAX1M Toughbooks that I installed these modems to. I hooked up the antennas. There is no dip switches. These are GOBI 4000 modems. I have visited the Carrier Software page over at Panasonic and installed the following files: MC7750_VZAccess_Manager_7-7-1-12-2763b.zip [zip, 27mb] MC7750_QMIDriverPackage_Build3644_Win7.zip [zip, 30mb] MC7750_03.05.10.9.zip [zip, 21mb] The OS is Windows 7 Pro 32 bit. All MS updates and all the Panasonic drivers are already installed. The only thing I can think to try is to re-install the wireless switch utility. Any thoughts or suggestions? I have an e-mail into Heartland as well (gag). Thanks!!
