yes Great, I can’t do that, I’m a Linux beginner… is there no real image with Luci?
you could try if on the ip ssh answers…try to make ssh connection with putty/minicom to the ip-address. better is having debug-uart to see all whats going on and have a fallback if you break your network-stack 
I do everything via UART Usb Adapter. because my problem is that the images all have the address 192.168.1.1… but my Fritzbox also die192.168.1.1. I can’t change the Fritzbox addresses because otherwise I would have to change the whole network.
ok, then you can also change ipaddress on the system, i’m not familar with openwrt but temporary you can change it like this:
ip addr del 192.168.1.1/24 dev lanbr0
ip addr add 192.168.1.200/24 dev lanbr0 // or something else
and then connect any of the lan-ports to you existing lan (so you have same subnet). for internet-access you have to set default route and dns-resolver
ip route add default via 192.168.1.1
dns-resolver depends on what openwrt is using, i guess @dangowrt can help here. debian/ubuntu uses /etc/resolve.conf or systemd-resolved
then you can install lucy and make all permanent network config there
OK I’ll try it now, I’ll get back to you right away… that’ll be fun 
Do this to change the LAN address permanently to 192.168.3.1:
uci set network.lan.ipaddr=192.168.3.1
uci commit network
reload_config
If you wish that the device simply connects to the existing router and uses DHCP to acquire an address, you may do so as well:
uci set network.lan.proto=dhcp
uci commit network
reload_config
(then you need to check your main router to find the address it assigned to the R3 which uses hostname ‘OpenWrt’ by default)

Did you add LuCI to the list of packages to be installed in the firmware-selector? It is not installed by default in snapshot builds, but you can add it quite easily:
Colleagues, slowly slowly… I’m a beginner !!! I have made:
- ip addr del 192.168.1.1/24 dev br-lan
- ip addr add 192.168.1.200/24 dev br-lan
- ip route add default via 192.168.1.1
- ip: RTNETLINK answers: File exists
did something go wrong with the last command?
Do I have to type that in manually with the keyboard?
When I enter “luci-ssl-wolfssl” manually with the keyboard I get this error message.
can confirm that it does not work for me too…if i add luci-ssl build is successful, but package-list has luci dropped
I’m too stupid for that, can’t someone make me an image for an SD card? otherwise I can throw the device away,… I’ve been trying to do it for over 2 months now.
Sorry, try with just luci-ssl (which is actually still the wolfssl variant, we are about to change back to mbedtls, which is why I’m confused about it).
something works with luci-ssl. but what after that? can i download this as an image somewhere?
Yes, just click on one of the links to the ready-made images below.
do I understand it right? I have to put it in “Customize installed packages” and below comes out the finished image for SD card ?
Exactly. You edit the list of packages in “Customize installed packages”, then you click on “Request build” and then you can download the ready-made image below. If the exact same combination of packages has already been requested for this device, everything will happen very fast as the images are cached for some time.
I just tried it, I can get the img. Download the file, it is about 21KB in size. I can write them to the SD card with Win32disk Imager But: something is wrong with the file, the R3 shows me via UART "System halt! "
The file I see there has 21MB and is gzip compressed. Before writing it to an SD card, you will have to decompress it (like you did with previous images).
Edit: No idea how one would handle gzip compression on Windows, probably 7zip can do the decompression for you.
yeah, I somehow got it unpacked under Windows with WinRar. the image is burned, the R3 boots, and lucy starts !!! guys you are great!!! Thank you.
do you have a tip which packages I should install?
