I notice that the UKBillion7800NV6_1.06d.zip file seems to indicate a "V6" router, does this mean the firmware is unsuitable for my older 7800N Router, or are they all V6 or will it just update to V5,4,3,2,1?? Spec?
I can't seem to see even what my Router version is in the web GUI *sigh*
to recap
1, is the UKBillion7800NV6_1.06d.zip firmware safe for all routers?
2, how to tell which version I have
3, how to get V1,2,3,4,5 firmware?
