[SOLVED] How do I get my wifi setup?

[decuser]

I've read and re-read https://wiki.gentoo.org/wiki/Handbook:AMD64/Networking/Wireless/en to no avail. Here's what I see in ifconfig:

3: wlp1s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN group default qlen 1000
link/ether cc:af:78:54:67:d3 brd ff:ff:ff:ff:ff:ff

I can't seem to change the state from DOWN to UP no matter what. Here's what I have done (per the wiki):

1. nano /etc/conf.d/net
https://wiki.gentoo.org/wiki/Handbook:AMD64/Networking/Wireless/en

2. nano /etc/wpa_supplicant/wpa_supplicant.conf
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
ap_scan=1

network={
ssid="my ssid"
psk="pw phrase"
# The higher the priority the sooner we are matched
priority=5
}

3. lacking any directive otherwise, fired up wpa_supplicant
wpa_supplicant -B -c /etc/wpa_supplicant/wpa_supplicant.conf -i wlp1s0

4. ran dhcpcd
dhcpcd wlp1s0

No errors, but no worky either. This works fine on my other laptop and I'm able to ping yahoo, but on this machine, it stays DOWN.

Help. Is there another way to configure the net post install (the wifi page says WPA_SUPPLICANT is preferred and necessary for WPA).[/url]

More info - as it turns out, these steps do work from the installer, they just don't work with the installed system. So, how do I troubleshoot - do you think it's a module issue?

[decuser]

Well, it looks like all of the same modules are loaded:

I struggled a little bit with that, too.
Just do https://wiki.gentoo.org/wiki/Wpa_supplicant#Minimal_configuration but don't get confused all you really need to do is:

I've had the most success replacing wpa_supplicant with iwd.
In this configuration, only iwd and dhcpcd services are started. net.* services are removed from startup.
Once started, the network selection and passphrases are set with either iwctl on the command-line or net-wireless/iwgtk in a GUI.

[decuser]

OK. Figured out how to run wpa_supplicant verbose (-dd). It looks like it matches on the SSID correctly, but then it gets:

wpa_parse_wpa_ie_rsn: invalid group cipher 0x8 (000fac02)
wpa_parse_wpa_ie_rsn: invalid group cipher 0x8 (000fac02)
skip RSN IE - parse failed
skip WPA IE - GTK cipher mismatch
reject due to mismatch with WPA/WPA2

Well, that's progress. I'm off to researching, but if you recognize it lemme know, please:).

Well, that didn't take long:

and

It seems to be an issue with tkip and ccmp being enabled. The "solution" is to add TKIP to the USE flags (or, I guess disable TKIP in the router)... I'm dubious about disabling it since I've not any issues with my setup until now. Updating USE flags sounds reasonable, if janky. How does that work? Off to reading that part of the handbook more carefully as I didn't mess with the flags on this first inst[/url]all...

The router doesn't have a "disable TKIP", it's just TKIP/AES or no. So, in the meantime, problem "solved"

USE="tkip" emerge wpa_supplicant

then restart wpa_supplicant, use dhcpcd to get an ip, and ping away, yay!

What's interesting is that I didn't need to be connected to the internet to do the emerge... is that because I previously got the package and it's just using the version I got before? So much to learn, so little time.
