Hi everyone,
I upgraded to 24.10 yesterday on my Fritz!BOX 7530 and unfortunately my guest network & wifi no longer appear to be working.
I probably created the network using this guide: https://openwrt.org/docs/guide-user/network/wifi/guestwifi/guestwifi_dumbap. I just tried deleting everything and recreating the network the same way, but appear to have the same problem: no IP address in the guest network range (192.168.9.x). I tried setting one manually, inc. DNS but actually still no joy.
I haven't carefully checked the new versions of configs after the upgrade, so perhaps there's some change there that I need to make? This seems like the most likely thing
So posting here for here, please
