raspberry-pi - 拔下局域网电缆时，Raspberry Wifi 失去连接

问题描述

使用最新的 Buster 版本，我可以设置我的 wifi 和 lan，它工作正常。但是，如果我移除局域网电缆，则无法通过 wifi 连接。Pi 甚至无法被 ping 通。我正在使用一个 dhcpcd.conf 文件，该文件与拔下 LAN 电缆时工作的另一个 Raspberry 相同。我错过了什么？

这是 dhcpcd.conf 文件

# Allow users of this group to interact with dhcpcd via the control socket.
#controlgroup wheel

# Inform the DHCP server of our hostname for DDNS.
hostname

# Use the hardware address of the interface for the Client ID.
clientid
# or
# Use the same DUID + IAID as set in DHCPv6 for DHCPv4 ClientID as per RFC4361.
# Some non-RFC compliant DHCP servers do not reply with this set.
# In this case, comment out duid and enable clientid above.
#duid

# Persist interface configuration when dhcpcd exits.
persistent

# Rapid commit support.
# Safe to enable by default because it requires the equivalent option set
# on the server to actually work.
option rapid_commit

# A list of options to request from the DHCP server.
option domain_name_servers, domain_name, domain_search, host_name
option classless_static_routes
# Respect the network MTU. This is applied to DHCP routes.
option interface_mtu

# Most distributions have NTP support.
#option ntp_servers

# A ServerID is required by RFC2131.
require dhcp_server_identifier

# Generate SLAAC address using the Hardware Address of the interface
#slaac hwaddr
# OR generate Stable Private IPv6 Addresses based from the DUID
slaac private

interface eth0
static ip_address=192.168.0.22/24
static routers=192.168.0.1
static domain_name_servers=192.168.0.18 8.8.8.8
static domain_search=

interface wlan0

解决方案

我找到了一种方法来完成这项工作，但我不明白为什么我必须这样做。我更改了每个的指标值，并使 wifi 具有更高的优先级（较低的数字）。这似乎使它起作用。
