I confirm the information in this thread to be helpful.
I had the same problem and found a solution here.
My “Huawei e3372h-153” after connecting it to the GL.iNet router in “Theter” mode (as 3G/4G is not available) was rising warning that IP 192.168.8.1 is in conflict. I confirmed that both GL & Huawei were using it by:
I went in GL admin panel to “MORE SETTINGS > LAN” and this message was displayed:
GL routers use 192.168.8.1 as the default LAN IP address. This is the address you would enter into your browser 's address bar to access the router admin page. You can manually setup one within these three ranges:192.168.x.x , 172.x(16-31).x.x or 10.x.x.x
Note: The starting IP address and ending IP address must be in the range of 2~254, and the ending address should be greater than starting address.
Setting that was not working:
LAN 192.168.8.1 - default
LAN 192.168.8.2 - that’s what I tried first
Solution - setting that worked:
My perspective of this situation as a user:
I wish the “Thetering of some 4G USB routers instead of ‘3G/4G USB router’ option” was explained a little bit more in the manual. And that IP confing too - like I’ve changed LAN 192.168.8.1 to LAN 192.168.8.2 and it was no working but LAN 192.168.8.1
LAN 192.168.7.1 worked and I do not understand why there were separate adressess after all!
On the topic of power:
I unplugged GL router from USB PC and plugged it to my smartphone charger. But this did no effect. When setting the above LAN IP options it works just fine connected to USB 3 PC (but to a smartphone charger as well). I think people rising problem with that were using older USB that had less power.
Big thank you all for your help! GL.iNet routers are the best!
