EC25-AF module connects but can't get interent

Hi i purchased a mifi type device from a manufacturer with a quectel ec25-af module. The device is running a custom version of LEDE 17.01.05 as the web interface is completely different. I'm having issues getting the LTE to connect. It actually connects per the logs and gets an IP from my provider but internet access doesn't seem to work.

I came across this patch while researching:

Could this be the cause of my issue? If so how would I go about fixing this. I'm a total newb to openwrt.
