Yenda, one more question - did you had the opportunity to try out OpenWRT + Huawei E3372 combination and based on that can you confirm these two are not compatible?

Hello,
no news - actually, as I needed to run it rather soon I bought a different LTE USB stick ZTE MF 823 and had to use OpenWRT... now working like a charm with a LTE speed
Yes I can confirm the Huawei E3372 is not working for me. Please note: There are two main FW in E3372 - one which act as modem device and you have to connect via ppp and second with so called Hilink, which should from my opinion work. I've had the non-hilink one and I was not successful at all.
You should see the hilink device as an USB0 (or something similar I believe) and you can get an IP address via DHCP from it (this is how it works with ZTE, currently on OpenWRT only).
Same question as the above.
I've flashed the latest firmware from the 16th to my TP Link MR3020 but the mobile connection just stays as disconnected no matter what i do.
WAN status shows correctly HiLink's Gateway and DNS (192.168.8.1). The internet connection status light is on with Asus router. But finally can't access to internet.
Lately, I've managed to get it working on my old WNDR3700v2. This modem comes in two versions:
firmware 21.xxxx <- non hilink, works like a standard usb modem
firmware 22.xxxx <- hilink, creates ethernet interface and works like router
I suppose, to use this modem as a hilink device, your DD-WRT router needs to have usbnet and cdc_ether modules installed in, and then all you have to do is to setup WAN interface to newly created eth2. This might be done by modyfying iptables, routing table or even in GUI, i.e. add this script as startup script:
Code:
insmod usbnet
insmod cdc_ether
ifconfig eth2 up
udhcpc -i eth2
On mine Netgear WNDR3700v2 (DD-WRT beta 3.0, build 40559) this wasn't option as there was no cdc_ether module. Ofcourse one can try to cross compile this module and upload it on jffs, but as I worked with Windows machine and had limited time this wasn't option either.
I've decided to use it as a standard serial modem, which is not best idea if one is counting on super-high LTE connection speed, but it works well with DD-WRT. The maximum download/upload speed would be ~30 MB/s. For my needs this was ok, as I'm using it in non-urban area, where even in hilink mode 30 MB/s is hard to achieve.
Now what I did is I've reflashed my e3372s-153 device to be non-hilink (there are plenty of tutorials over internet how this might be done), downgrading it's firmware to version 21.xxx.
Since then my router detected this device as a standard Huawei modem ("cat /proc/bus/usb/devices" showed it as vendor id: 12d1 and product id: 1506), and 2 ports have been created: /dev/ttyUSB0 and /dev/ttyUSB1. The problem with this device are these interfaces. As LOM stated earlier, most Huawei devices in the past had modem interface on first serial port, this one's have it on second port. This feature may be changed by sending proper AT command to modem. In order to do this I've decided to use an old comgt program built in DD-WRT (by the way, why not upgrade'ing to gcom?):
First plug in modem into USB port, login to router via telnet (use Putty for example), and then create new comgt scritp, type:
Code:
cat >> /tmp/setport.comgt << EOF
opengt
set com 115200n81
set senddelay 0.02
waitquiet 1 0.2
flash 0.1
print "Changing port configuration\n"
send "AT\^SETPORT=\"FF;1,12,16,A2\"^m"
waitfor 15 "OK","ERROR"
if % = 0 goto reset
if % = 1 goto senderror
goto timeout
Next, login to DD-WRT via web GUI, in setup choose Mobile Broadband connection as your WAN, type proper APN, user nad password, reboot and that's it, your E3372 should be working.
Now, as You switched the default ports, the E3372 won't be working on Windows machines anymore without swithing them back manualy. To switch port settings back to factory settings use the same method but change:
Code:
AT\^SETPORT=\"FF;1,12,16,A2\"
to
Code:
AT\^SETPORT=\"A1,A2;12,1,16,A1,A2\"
Mine E3373 works very stable and connection rate is 30 Mb/s download and about 25 Mb/s upload. I'm usnig it in my vacations country house with 2 external, 16dB directional antennas, where normal 4G smartphones have very weak signal. I must addmit I'm very glad of finding serious usage for my old Netgear instead of simply throwing it away as garbage. Environment first
