Xiaomi Redmi Router AC2100
OpenWrt 22.03.0
In some cases, the wireless drivers used in OpenWrt do not support “Layer 2” bridging in client mode with a specific “upstream” wireless system. When this occurs, one approach is to route the traffic between LAN and the upstream wireless system. Broadcast traffic, such as DHCP and link-local discovery like mDNS are generally not routable.
