Re: Struggling to Get an Edimax EW-7811UN Wifi Adapter to Work

The dmesg output you passed through grep.  See post #8,  #13, #15 and #16 where you are being asked for the output without the use of grep.
The rest of the last output looked good.  You should then have a connection without an IP address.  Dhcpcd to start DHCP on that interface.

Re: Struggling to Get an Edimax EW-7811UN Wifi Adapter to Work

I'm literally in the home-stretch! I'm going to post all of my wpa_supplicant outputs here for final debugging and help.

I initialize wpa_supplicant:

[george@archlinux ~]$ sudo wpa_supplicant -B -i $INTER -c /etc/wpa_supplicant/wpa_supplicant.conf
Successfully initialized wpa_supplicant

I then run wpa_cli:

[george@archlinux ~]$ sudo wpa_cli
wpa_cli v2.6

See README for more details.


Selected interface 'wlp0s20f0u6'

Interactive mode

Then I do the following:

> scan
OK
<3>CTRL-EVENT-SCAN-STARTED 
<3>CTRL-EVENT-SCAN-RESULTS 
<3>CTRL-EVENT-NETWORK-NOT-FOUND

These seems problematic, but scan results seems to be fine (I changed the results for privacy, shouldn't effect the nature of the problem):

> scan_results

b8:8d:12:60:e5:8b	2437	-38	[WPA2-PSK-CCMP][ESS]	Gary Mandel's Network

Then I run the following to connect to the main network:

> add_network
0
> set_network 0 ssid "Gary Mandel's Network"
OK
> set_network 0 psk "6304287649"

I feel like I'm so close to get this to work, any input will be highly appreciated! (And yes, I did alter the network info for confidentiality purposes)

I haven't done anything with DHCP yet, was that why I was having issues for my last humongous wpa post?

EDIT:

Is this all I need to do?:

[george@archlinux ~]$ systemctl start dhcpcd.service

Authentication is required to start 'dhcpcd.service'.

Re: Struggling to Get an Edimax EW-7811UN Wifi Adapter to Work

That would start it on all interfaces.  I was expecting you to either use `dhcpcd enp0s20f0u6` or `systemctl start dhcpcd@enp0s20f0u6.service`
Did you execute save_config with wpa_cli?
The service is started now so what is the output of `ip a`.

Saved wpa_cli even though I got the error. Also, I installed using NetworkManager, so shouldn't I use that instead of dhcpcd?

Re: Struggling to Get an Edimax EW-7811UN Wifi Adapter to Work

NetworkManager is an alternative to wpa_cli / dhcpcd having both attempting to control the same device leads to issues.
No carrier on wlp0s20f0u6 so you can stop all the dhcpcd services you started the association step with the access point failed.

Yep, that's what did the trick! Must be why all the other alternatives didn't work. Now I just need to find a way to get this to work automatically on boot.

Ensure the following are installed;

wpa_actiond
wpa_supplicant
dialog

Then;

$ systemctl enable --now netctl-auto@enp0s20f0u6.service
$ wifi-menu

... # log into your wireless network via dialog ...

Interface 'enp0s20f0u6' is controlled by netctl-auto
$

Moving forward, just connect to a wireless network via that interface with wifi-menu.
The profiles will be stored in /etc/netctl/

See;
https://wiki.archlinux.org/index.php/Netctl#Wireless
