6. Use
ifconfig

Now it is possible to browse the Internet.
D Optimal throughput
To reach the highest throughput use one of these interfaces, which are listed with most optimal first:
• the RNDIS interface
• the CDC-ECM interface
• the CDC-ACM interface
The configuration can be set by means of the +UUSBCONF AT command (see the u-blox AT
commands manual
[1] ).
☞
On a Linux OS to reach the highest throughput through the RNDIS, it is necessary to recompile
the kernel. Apply the following modification in
/kernel/drivers/net/usb/usbnet.c
:
replace "size_t size = dev->rx_urb_size;" with "size_t size = (16*1024);"
If it is not possible to recompile the kernel, try to use the following command:
AT+UDCONF=67,0
This command disables RNDIS driver optimization and can mitigate effects in router mode only.
