Hi Charles, thanks for your email.
I’m trying to answer all the questions…
No changes at all since last time I used back in May 2025.
I can’t connect to the box on wifi, only by cable through Microbit utility.
No changes in DHCP, remain the same.
I am connecting the box to the router directly with Ethernet cable.
I configured the boxes so they have been working correctly for 2 years now. Set the remote in October every year and dismantle it in May.
Ports are correctly open like in the RRC boxes manual.
IP address is the same, checked that and remains the same.
DDNS can be the problem I think. Looks like it doesn’t connect with remoterig.com, so they don’t get updated, but don’t know how to do it..
I would say is a connection problem.
I changed the router months ago, but since there is a cable connecting the box and the router, I don’t see any issue there, but…. Why can’t I connect to the box via wifi.?
Thanks.
