so i swapped out my bt homehub 5a with OpenWRT for a draytek 2762ac, i enabled 5G and 2.4G, on the 2.4G channels i kept the SSID the same name, i kept the password the same.
i messed about for ages trying to move it to the new wifi, i reset it, reset the app, many times, each time it connects and tells me that its all setup but then never shows in the app
i see it has a DHCP IP address, my phone is on the same network during the setup etc.
any ideas ? i spoke with support chat they told me to remove band steerring etc, enable upnp (nope) and a few other things that the router seemed to have set already but the weird thing is that it seems connected as i see it in the arp table and dhcp table but the app never sees it, the app (IOS) has full network access.
i am lucky in that i can connect it via an ethernet cable but even though i can im not sure why it would suddenly stop working on wifi
