I've set this up twice so far, and both times everything works great. I use reserved addresses for everything to avoid unexpected conflicts. The 2nd day, most of my WiFi connections are gone. One device just connects and drops over and over. The rest just won't connect any more The signal strength doesn't appear to be a problem though. So far, this is by far the hardest router I've ever owned! LOL Any ideas at all?
It's impossible with only a vague description of your problem.
Let's start with the config:
Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button (red circle; this works best in the 'Markdown' composer view in the blue oval):
Remember to redact passwords, VPN keys, MAC addresses and any public IP addresses you may have:
ubus call system board
cat /etc/config/network
cat /etc/config/wireless
cat /etc/config/dhcp
cat /etc/config/firewall
