Problems with not being able to save changes is usually related to a corrupt SD Card filesystem (which can happen easily on an RPi). Do you see "Unsaved Changes" in the upper right corner? If so, more recent RPi versions of ROOter include a filesystem check and repair menu item. Run that and reboot.ciarlill wrote: ↑Wed Jul 29, 2020 7:56 amIn the meantime I noticed something strange... I wanted to disable WiFi on the ROOter device to cut down on extraneous networks floating around. Although I can access the configuration page at 192.168.3.1 I cannot actually save any configurations, it just times out and appears to be redirecting me back to 192.168.1.1. It works fine if I plug directly in and access on 192.168.1.1. Wondering if you have run into this and have any ideas on anything I might have missed in setup. It seems like one of the additional benefits of this approach is actually being able reach all the devices on their own VLANs for additional configuration as necessary.
Whether that turns out to be the issue or not, be sure to always do a proper shutdown from the ROOter menu system. Pulling the power cord on an RPi actively running any version of OpenWRT, very often results in the need to do a filesystem repair.
If that's not the culprit, I'd suggest confirming your new VLAN is part of the LAN firewall group. This can be easily verified by checking the header colors under Network - Interfaces. Those that are part of the same firewall group will have the same color header. Mine is green for the LAN group and pink for WAN.
