> You're right. ModemManager can drive the /dev/wwan0mbim0 just fine. For some strange reason, when compiling the patched drivers as part of the kernel config, it wouldn't recognize the modem even though the devices were there.

For using MBIM, you can issue the commands (of put it in a boot script):

```auto
ifconfig wwan0 up
mbimcli -d /dev/wwan0mbim0 --query-subscriber-ready-status --no-close
mbimcli -d /dev/wwan0mbim0 --query-registration-state --no-open=3 --no-close
mbimcli -d /dev/wwan0mbim0 --attach-packet-service --no-open=4 --no-close
mbimcli -d /dev/wwan0mbim0 --connect=access-string='<YOUR ISP APN STRING>' --no-open=5 --no-close
udhcpc -q -f -i wwan0 -x lease:864000

```

You need to install **kmod**  **bbr** and paste the following lines into **/etc/sysctl.conf**

```auto
net.ipv4.tcp_congestion_control = bbr
net.ipv4.tcp_adv_win_scale = -2
net.ipv4.tcp_notsent_lowat = 131072
net.ipv4.tcp_timestamps = 0
net.ipv4.tcp_mtu_probing = 1
net.ipv4.tcp_sack = 0
net.core.netdev_max_backlog = 1048576
net.core.rmem_max = 16777216
net.core.somaxconn = 65535
net.core.wmem_max = 16777216
net.ipv4.ip_local_port_range = 1024 65535
net.ipv4.tcp_fin_timeout = 5
net.ipv4.tcp_max_orphans = 1048576
net.ipv4.tcp_max_syn_backlog = 20480
net.ipv4.tcp_max_tw_buckets = 400000
net.ipv4.tcp_no_metrics_save = 1
net.ipv4.tcp_rmem = 4096 87380 16777216
net.ipv4.tcp_synack_retries = 2
net.ipv4.tcp_syn_retries = 2
net.ipv4.tcp_tw_reuse = 1

```

Try these tweaks by pasting the following lines into **/etc/rc.local**

```auto
echo 524288 > /sys/module/nf_conntrack/parameters/hashsize
echo 'on' > /sys/devices/platform/soc/11280000.pcie/pci0000:00/0000:00:00.0/0000:01:00.0/power/control

```
