Most Huawei modems require some minor configuration, if more than one is used. This article will show the needed steps to make the modems fully functional. Huawei modems give out the same subnet/IP, which causes an IP conflict, which leads to one connecting and then the other disconnecting and vice versa. When using multiple Huawei E8372h modems, which also create a built-in Wi-Fi hotspot, it's recommended that you also disable the built-in Wi-Fi hotspot on each E8372h modem. I would say to reach the modems configuration with a laptop or PC, to see what IP info is set for both modems. The USB IP Address is typically 192.168.2.2.
- Connect the modem to a desktop or laptop, then open a web browser, and go to 192.168.2.2 (default IP address). Once you reach the modem's configuration site, login (default username: admin , default password: admin).
- Once you're logged in, go to Settings. Once you're in Settings, click on WLAN, and once the drop down list appears, click on DHCP.
- Once you're in DHCP, just change the third octet of the IP address (anything besides 1 or 2; in this case I chose 8). Once that is changed, click on Apply.
- Just as a security/bandwidth measure, we recommend disabling the Wi-Fi option. You would just have to go to Settings, click on WLAN, then click on WLAN Basic Settings. Once you're in WLAN Basic Settings, disable the WLAN module and lastly click Apply.
I still had an issue after following this article.
As I have two the same modems, they come pre-configured with the same IP address. I modified the last digit too of the IP address and that fixed my bouncing between ready and disconnected.
The problem is that "most Huawei modems" have firmware that does not have the option to change ip-address. And not all Huawei modems work at all, even if it is on the modem list... On the list, it currently says that "Huawei E3372" Works. But the truth is that "Huawei E3372h-153" does not work at all. And for the "Huawei E3372S" does work, but only if you use one modem - if you try to use two Huawei E3372S they get in ip-conflict With each other, and there is no way - in the current firmware - that you can change ip-address on this modem. Some have managed to install an old modified firmware that let you change ip-address, but I have not managed to do so.... I have spent lots of hours and lots of Money on USB-modems for the last couple of weeks…. Really frustrating since it not easy to find a reseller for the different USB-modems.
It is very unfortunate that customers are not warned in advance to Bent’s issue. Still presentv
