Huawei E3372h-153 USB 4G stick working on Rpi4
Just want to report I have the Huawei E3372h-153 USB 4G stick working on my RPI4 running Buster without any modifications to the stick.
I bought this stick to have backup for internet as in these times online seems to be the only way to do anything..
I normally have an older Huawei 3372 model in an old raspi1 used as router. it needs usb_modeswitch and ppp to connect to the internet.
The new stick E3372h-153 seems to have some Linux build in and appears when running ifconfig as
enx0c5b8f279a64: flags=4163 mtu 1500 inet 192.168.8.100 netmask 255.255.255.0 broadcast 192.168.8.255 inet6 fe80::4b0:4fe1:bfbe:c9c8 prefixlen 64 scopeid 0x20 ether 0c:5b:8f:27:9a:64 txqueuelen 1000 (Ethernet) RX packets 4 bytes 960 (960.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 28 bytes 4197 (4.0 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
so is assigned IP address 192.168.8.100 here, and at the same time that IP is added to the routing table 192.168.8.0 0.0.0.0 255.255.255.0 U 288 0 0 enx0c5b8f279a64
The stick now presents a web interface on 192.168.8.1 So point your browser to 192.168.8.1 there you can specify the PIN code and start/stop the internet connection, some more options.
It is not so much suited for router, but I could surf the web on my P4 with it. Also you can add IP addresses to this a bit strange (my LAN is on 192.168.198.XXX) for example raspi95: ~ # ip addr add 192.168.8.1 dev enx0c5b8f279a64
I did an ifconfig eth0 down before testing internet access, dhcpd assigned 192.168.178.95 to that,, not sure that was needed. All done on the Pi 4 directly, not via ssh. Normal SIM card is a KPN internet only 10GB/month.
All this as opposed to wild stories on the web about endless failed attempts re-flashing being needed for that Huawei model, So very good, basically plug and play in the Pi4 and a nice web interface.
The BAD part is that the piece of paper that came with the stick mumbles about auto-updates of the stick's firmware, :-( Will have to see if I can switch that off, it also babbles that by using it you agree to auto-updates... So maybe I should burn it anyways ;-), but as emergency net access for now it is OK and simple. Maybe auto-update can be switched off in that browser interface under security, have not looked yet, Anyways it works in spite of all the horror stories.
