I installed successfully the RP-WD03 (=RP) with the actual OpenWrt but I'm failing to configure it for my needs. The only success was the failsafe procedure which works without problems (tcpdump does the trick). Now I'm back to the default settings and able to login via the Web GUI and also via ssh.
The target is (in chronological order):
connect the RP via Ethernet or Wifi to my router at home and also on vacation (maybe Ethernet, most likely Wifi).
the RP should offer me a WLAN to get access to the internal SD-Card (SAMBA) and an internet connection. The devices in the LAN should be visible to each other.
The IP address of my router@home: 192.168.1.1/24, DHCP is of course enabled.
The device has one ethernet port and is able to use more than one concurrent Wifi connection.
I don't want a VPN - seems to complicated for me.
I configured successfully a connection to my Home WLAN (Client, DHCP).
Then I configured a WLAN on the device itself. I was able to connect to this WLAN with a smartphone but couldn’t reach the internet.
Then I tried to configure a bridge between both WLANs. Again - no success.
However - in the end I couldn’t reach the RP anymore so I started the failsafe procedure.
Now I'm at the beginning.
What's wrong with my configuration?
No I didn’t. I couldn’t find a receipt for my use case on OpenWrt so I'm currently lost in bridges, VLANs, subnetworking etc. What do you suggest to come to an easy solution? My use case seems typical for this kind of device.
I never got to the point to make this config work. I‘m a technical oriented guy but that’s not enough. You have to be a network specialist to make this work. If there is no receipt, this costs to much time to make it (if any) work.
I finally made it work today. After trying to become a preschool sysadmin by watching dozens youtube videos and trying to setup VLAN with wifis, I bumped into this post
Few tips
reset the openwrt
add internet for packages by setting up Network>Wireless>Scan
install travelmate (+cli) at Software > Update lists *make sure you got all dependencies
delete wireless network (Network/Wireless) and wan (Network/Interfaces)
reboot
Services>Travelmate >Interface wizard
connect (again) to your local wifi via Services>Travelmate >Wireless stations (status should be shown as 'connected' at this stage)
