I installed openwrt (snapshot) on my TP-link MR6400 (4G LTE) V5 router a couple of days ago, before installing openwrt the router was working fine, but now I don't have internet access. I tried a suggested solution I found by changing the LAN IP address to a different range, it didn't work either. My networking background is not very strong, could anyone here help me find the problem?
This is a screenshot of the /etc/config/network file:
I tried Ethernet&WIFI connection both of them did't have internet connection, I can ping other hosts in my network.
Instead of screen shots, please post your results in pre-formatted text using the icon highlighted in red...
Additionally, run cat /etc/config/dhcp and post.
What is upstream of your openwrt router (i.e. what is between it and the internet)?

That does not appear to be the complete file. Maybe try again.
i'm not sure if i understood you correctly but i'm using a 4G LTE router (SIM inserted in router) and my computer is connected to the router using Ethernet cable.
Did you configure the LTE modem?
Currently it looks like the device is expecting the WAN on the ethernet ports.
I don't personally know how to get your LTE modem up and running (I haven't use that device), but I think fundamentally the system isn't firing that up -- it doesn't know it is available as a WAN connection.
You might take a look at the User Guide...
