I'm New to the openwrt forum but not new to openwrt itself having ran it for many years on various devices.
I have bought a cheap Comfast CF-E3 and I was wondering would there be any support for it going forward in openwrt?
I've seen some activity regarding its bigger brother the CF-WR617 and someone managed to ssh into it - i was wondering if that user is around to tell me how they did this as there is zero documentation for these little routers out there.
I have managed to get into it via ssh using a helpful tip someone had posted about another comfast model.
It is running a variant of openwrt, either barrier breaker or choas calmer and uses a USB board mounted fibocom lte modem and relies on the varios usb scripts available for openwrt that youd use for a traditional usb dongle/modem.
Looks like it uses some custom packages to as i've compared it to other openwrt builds and these packages do not exist? for example "fibocom" package and "apn_detect"

So anyway the question n I really should be asking here is why this device works perfectly with an o2 uk simcard yet a vodafone uk one does not. It will get an IP from vodafone but no traffic flow - RX packets seem to flow but TX. I find the config seems to pay no attention to APN settings even if you write them to the network config manually and "sorts itself out" so to speak.
I did find a bit of info about "apn_detect" package and it would appear there is a list of APNs available for it to use in a text file somewhere - for which mobile.o2.co.uk is present but wap.vodafone.co.uk does not exist on the list - perhaps that is why it wont detect the apn for the vodafone sim but works with an o2 one?
if any 4g/lte guys could point me in the direction of shining a light on the cause or even some logs i would appreciate it.
also here are results of route command:

Thanks for the info, it may be of help to someone else now as unfortunately the unit I was testing with died totally. Completely unrecoverable via tftp/serial pins etc. That said before it died I did test it with r00ter and that sort of worked
