i couldnt get it to connect with att or tmobile sim. tried at+qcfg=“usbnet”,1 and it made things worse so i went back to “usbnet”,0 and it was back to what it was but still no connection. then i tried at+qcfg=“usbnet”,3 and now it wont respond at all and device manager says no drivers installed, ive tried uninstall and reinstall several times but i get the same no drivers installed error in device manager. need help undoing whatever i did and getting it to connect to lte.
I would recomend you try it on a Linux PC and set the EC25 back to RMNET mode (usbnet 3).
i dont have access to a linux pc. how can i change it back, right now its not responding to windows
Please uninstall the NDIS driver and just install the RNDIS driver.
!!!
RNDIS is not recommended for EC25 please not try it later.
i didnt install it. still using ec25 driver from exvist website, still wont connect. cant you just write a command list and save it then send it to me. one for at&t lte usa, one for tmobile lte usa. lte bands b2,b4,b12
You should install this one. And make sure that you have unistall any other Quectel USB driver.
For EC25 the RNDIS is not compatible with NDIS driver.
ok but i dont have access to that driver. please email it to me
Please check the message.
