influenist Posted May 10, 2020 Share Posted May 10, 2020 While the EM7430 works with my kext. (I guess the product ID needs to be adjusted still). The EM7455 seems not. What I did: Wrote the kext for DW5811e / EM7411 according to the correct PID & VID attached above. Which after it appears on WANN section (location id show xxxxxxxx / 0 as others also have in their screen). Then with the correct APN the error shows: So I updated the firmware and all config settings using LIVE UBUNTU CD 18.04 with: https://github.com/danielewood/sierra-wireless-modems His autoscript is perfect for updating FW, configuring the whole card according to our needs & sets the PID/VID to generic to bypass any vendor locks. Whilst I updated the kext to reflect all MC/EM7455 cards PID/VID (Lenovo / DELL / Generic). Still the error "Network Connection ... " shows. Please also see the location difference: NOTE the firmware: SWI9X30C_02.08.02.00 r5428 CARMD-EV-FRMWR2 2016/01/06 20:38:53 While at!priid? shows the updated firmware: SWI9X30C_02.33.03.00_00_00_GENRIC So I manually check the connection using COM port: screen /dev/tty.wwan 115200 screen /dev/tty.wwan 115200 Which after I'm able to manually connect using at commands. Any ideas where to look? Perhaps it is the interface mapping? <key>InterfaceMapping</key> <dict> <key>0</key> <dict> <key>name</key> <string>wwanDM</string> </dict> <key>2</key> <dict> <key>name</key> <string>wwanGPS</string> </dict> <key>3</key> <dict> <key>name</key> <string>wwan</string> </dict> </dict> 3 Link to comment Share on other sites More sharing options...
crazdgrunt99 Posted June 4, 2020 Share Posted June 4, 2020 I too have the DW5811e and am having the same issue did you get round to finding a solution? I'm on 10.15.5 however both my location IDs are the same but I still get the connection error. 1 Link to comment Share on other sites More sharing options...

miki991 Posted September 26, 2020 Share Posted September 26, 2020 Hi! Did anybody try setting modem port to 6 or 8 as described here?: https://osxlatitude.com/forums/topic/8006-sierra-wireless-qmi-modules-mcem73xx77xx8805etc-dell-dw557058085809etc/ Quote For Legacy use, Modem port must be enabled in configurations modules: example, USBCOMP = 6, or 8 @influenist this script that you mentioned sets the card in MBIM only (+AT) mode. If Im not mistaken for OSX and this kext we need to put the card in the mode that supports QMI mode also? Quote - Sets MBIM Mode with AT Commands Access https://www.ttl.one/2018/07/sierra-wireless-lte-autoflashing-em74xx.html So for example on this page that was linked scripts github page (https://zukota.com/sierra-wireless-em7455-how-to-enable-com-ports/) the modem supports mode 6,8, and 9, and was set in mode 8 that doesn't support QMI Quote 8 - DM NMEA AT MBIM SUPPORTED But if we set modem (manually, without script) to modem config 6, that mode support QMI Quote 6 - DM NMEA AT QMI SUPPORTED Can anybody please check if this solves this issue so I can go order this card on Ali? instructions here: https://zukota.com/sierra-wireless-em7455-how-to-enable-com-ports/ Link to comment Share on other sites More sharing options...

influenist Posted December 1, 2020 Share Posted December 1, 2020 Hey @miki991 , I tried all sorts of combinations yet can't remember exactly though if I followed up your notes. Even made the kext working for the 3 variants. I'll retry this at some later stage as I'm too caught up with work / private life. Why not buy the card and help the community ?! Attached the latest version I could find in my backedup EFIs. Legacy_Sierra_QMI.kext.zip Link to comment Share on other sites More sharing options...
