Panasonic CF-53 runnning Windows 10 is not recognizing a newly installed EM7355. Installed build 5087, still nothing. Any tips?

Hi @gdietrich,

You should try with the latest offical FW for your EM7355 module to avoid issue. You can get this FW at link: [https://source.sierrawireless.com/resources/airprime/software/airprime-em73xx\_mc73xx-fw-package-latest-release/#sthash.7yXcigZr.dpbs](https://source.sierrawireless.com/resources/airprime/software/airprime-em73xx_mc73xx-fw-package-latest-release/#sthash.7yXcigZr.dpbs)

Thanks,
