How to set up wireless network link in Raspberry Pi, I believe many inexperienced people are helpless about this, this article summarizes the causes and solutions of the problem, through this article I hope you can solve this problem.

Insert usb card, use command

ifconfig

If the following prompt appears, the wireless network card is already supported normally

wlan0 Link encap:Ethernet HWaddr e8:4e:06:2b:a1:d9 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:789 errors:0 dropped:1392 overruns:0 frame:0 TX packets:217 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0 B) TX bytes:0 (0 B)

Otherwise, the network card may not be supported, and drivers may need to be installed.

lsusb #Details man.linuxde.net/lsusb

Command to view inserted usb devices.

Configure the network, use commands

sudo nano /etc/network/interfaces

configured as follows

auto loiface lo inet loopbackauto eth0allow-hotplug eth0iface eth0 inet dhcpauto wlan0allow-hotplug wlan0iface wlan0 inet dhcpwpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

Then configure the/etc/wpa_supplicant/wpa_supplicant.conf file

sudo nano /etc/wpa_supplicant/wpa_supplicant.conf

configured as follows

country=CNctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdevupdate_config=1network={ ssid="ssid of wifi" psk="password" priority=1 id_str="home"}network={ ssid="ssid of wifi" psk="password" priority=2 id_str="home"}network={ ssid="ssid of wifi" psk="password" priority=5 #priority, the higher the number, the higher the priority, id_str="office"}

Configuration basically completed, restart wireless network card

sudo ifdown wlan0sudo ifup wlan0

If there is no problem, you should be able to access the Internet.
