Can't directly flash OWrt 18.0 from stock firmware's web interface and sysupgrade
So my question is, how do I flash a brand new GL.iNet GL-B1300 with OpenWrt 18.06.1?
Installed is Firmware 2.272 and in the advance section I see Chaos Calmer 15.05.1
I found https://forum.gl-inet.com/t/b1300-unable-to-update-to-lede/3032/ which mentions a lot of probelms, but not with OpenWrt 18.06.1.
Unfortunately I didn't find a howto for flashing at GL.iNet, what have to be done exactly.
So can anyone tell me what works?
My first problem is, that I cannot connect with an ethernet-cable to a notebook, but via Wifi.
Which port do I have to use, when I connect via ethernet cable, wan or lan?
