Just upgraded my EM7565 to the latest generic firmware and carrier aggregation is not working any longer. If I revert back to fw version: 01.07.02.00 GENERIC\_002.004\_001 it works with everything else being the same. Any ideas on what I might be missing? ---

Hi @scm Did you use 9999999\_9907259\_SWI9X50C\_01.14.02.00\_00\_GENERIC\_002.035\_000.exe file to update the EM7565 firmware? [AirPrime EM75xx Approved FW Packages](https://source.sierrawireless.com/resources/airprime/minicard/75xx/airprime-em_mc75xx-approved-fw-packages/#sthash.KKyVwSd1.dpbs) This issue cannot be reproduced after I updated to the latest generic firmware EM7565 SWI9X50C\_01.14.02.00. The log file is attached.[log.txt](https://forum.sierrawireless.com/uploads/short-url/AdUwGqukKcsAx4ilEaVSltT0EPK.txt) (327 Bytes) Could you please provide some information about your module and SIM card using below commands?

Thank you for any help/insight. It looks like it should be doing CA but it never actually does and the speed drop from the old firmware does not make sense (nothing else has changed). AT!CUSTOM?
