Quectel RM551E-GL

[SpeedxThunder]

so installed the mbim driver but in device manager it was either generic mobile broadband internet or ecm

so i used generic one

To be safe, if you have not restarted pc after installing mbim driver. do so now. Check again, is there any particular error shown when you activate the broadband in windows with mb driver? Check qnavigator screen when connection is activated in windows.
If not working, then try these manual commands and report response

AT+CGACT=1,1
AT+CGPADDR=1

Does the device show up under modems? What is the response to

AT+QCFG="data_interface"

 

[SpeedxThunder]

will there be seperate mobile broadband section in windows network panel?

it was there in NDIS mode but not in MBIM mode

Did you set jionet apn manually? It does not seem to be correctly set. Execute this

AT+CGDCONT=1,"IPV4V6","jionet"

Then try AT+CGACT=1,1 and see if there is an error
When you put it into mbim mode, and correct drivers are present, windows should automatically set up a cellular connection and that will be visible in network connections with the mobile interface driver. It may sometimes have a wrong driver configured.

Is any modem visible under modems in device manager? See if any devices are present with a question mark in device manger that show up when you connect the device to pc. Pics of "Network and Internet Settings" and "Network Connections" would be useful. If nothing else works we can put into ppp mode, setup a modem even if none are present and then use a dial up connection.

My ec25e is inside an openwrt router presently, but here's how the simcom sim7600 dongle appears in windows even without a sim inserted. When sim is inserted 'Cellular 2' changes to operator name like JIO etc Network Present in Network connections NetConn

Now you're getting AT+CGACT=1,1
Since you have quectel usb modem, just create a new dial up connection using that modem with *99# as phone no and you should be good to go

damn, so now dailing up works but since jio works on ipv6 only its not working in ipv4 sites
