Hello everyone , recently installed OpenWrt on my AX3600 Xiaomi ( Snapshot with LUCI ) , but having some problems using DHCP , on wired and wireless connections .
wireless authenticate just fine , but fails to get an IP .
LAN just fails to get an IP
devices works fine if assigned static IP addresses and do connect to the network
any help would be appreciated
thanks .
Without config information, we can't even guess what might be wrong.

In the dhcp config below, remove the netmask and edit the start to be just 2 instead of 192.168.1.2. There is another problem -- the limit of 98 means that it will overlap the IP address of the router on the lan itself (192.168.1.86 -- more on that below).
Is there any reason you've changed the lan address from the default 192.168.1.1 to 192.168.1.86? As noted above, it will currently conflict with your DHCP pool.
