 |
|
Hi,
I need some help getting my wifi to work during installation. I am using systemrescuecd and I have followed the steps here to configure my wifi with wpa_supplicant
| Code: |
livecd ~ #wpa_passphrase "ESSID" > /etc/wpa.conf
<then type your WiFi access point passphrase (without quotes) and press Enter>
livecd ~ #chmod -v 600 /etc/wpa.conf
livecd ~ #cat /etc/wpa.conf
livecd ~ #wpa_supplicant -Dnl80211,wext -iwlp2s0 -c/etc/wpa.conf -B
Successfully initialized wpa_supplicant |
After this when I ping www.google.com it says it cannot resolve the name.
When I ping with the IP address instead it says host unreachable.
I tried using net-setup as well but was unable to get my wifi working.
How can this be done? |

| Probably after using wpa_supplicant you need to get an IP address with DHCP or something like that. |

pdv,
Welcome to Gentoo.
A wifi interface is like wired but with the extra steps to establish the radio link.
wpa_supplicant only does the extra steps.
Check dmesg to make sure you have your wifi both associated and authenticated.
When that's good the radio bit works.
Look at the SSID it connected to too. It might not be yours.
Now do | Code: | | dhcpcd <interface_name> |
Look in ifconfig for an ipaddress. My wired looks like | Code: | $ ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.100.20 netmask 255.255.255.0 broadcast 192.168.100.255 |
If your address starts 169. you have other problems. That means that no dhcp server was found.
Essentially, your router could not be contacted.

Thanks for taking the time to reply.
The output from dmesg -i -E 'x: xx.x|wlp2s0' was:

Unfortunately, I don't know how to interpret this. |

I managed to connect.
I created /etc/wpa_supplicant/wpa_supplicant.conf
Put in
| Code: | ctrl_interface=/run/wpa_supplicant
update_config=1 |
Then ran
| Code: |
wpa_passphrase SSID password >> /etc/wpa_supplicant/wpa_supplicant.conf |
Then ran
| Code: | killall wpa_supplicant
wpa_supplicant -B -i <interface> -c /etc/wpa_supplicant/wpa_supplicant.conf
dhcpcd |
