Raspberry Pi 3 B+ Wifi設定

最近自己買了一塊最新的Raspberry Pi 3 model B+

那這裡來寫一下和分享一下我的wifi的設定和過程

先到以下連結去改網路的國碼：

然後使用rfkill list指令查看無限裝置的開啟狀態：

$ sudo rfkill list

yes就是被鎖住了，沒有開啟，所以要把全部都設為no，可以參考剛剛上面的連結去設定。

然後要改改網路相關的設定檔
修改WiFi網路設定檔dhcpcd.conf

$ sudo nano /etc/dhcpcd.conf

# A sample configuration for dhcpcd.
# See dhcpcd.conf(5) for details.

# 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
# Most distributions have NTP support.
option ntp_servers
# Respect the network MTU. This is applied to DHCP routes.
option interface_mtu

# A ServerID is required by RFC2131.
require dhcp_server_identifier

# Generate Stable Private IPv6 Addresses instead of hardware based ones
slaac private

# Example static IP configuration:
#interface eth0
#static ip_address=192.168.0.10/24
#static ip6_address=fd51:42f8:caae:d92e::ff/64
#static routers=192.168.0.1
#static domain_name_servers=192.168.0.1 8.8.8.8 fd51:42f8:caae:d92e::1

# It is possible to fall back to a static IP if DHCP fails:
# define static profile
#profile static_eth0
#static ip_address=192.168.1.23/24
#static routers=192.168.1.1
#static domain_name_servers=192.168.1.1

# fallback to static profile on eth0
#interface eth0
#fallback static_eth0

SSID 你的SSID
static ip_address=192.168.11.122
static routers=192.168.11.1
static domain_name_servers=192.168.11.1
netmask 255.255.255.0

這是我修改完的樣子

修改/etc/wpa_supplicant/wpa_supplicant.conf

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=TW
network={
 ssid="你的SSID"
 psk="wifi密碼"

}

修改完的樣子

然後應該是要讓設定生效，我很像是直接重開機，用ifconfig指令查看一下網路狀態，會看到已經有IP了，ping 8.8.8.8如果有ping到東西就是有網路了。

之前以為/etc/network/interfaces也要改，但似乎不用，以上兩個檔案改完就可以了。
設定檔的更改是參考這篇：http://wuhsiublog.blogspot.tw/2017/01/raspberry-pi-3-wifiip.html
