[Solved] Intel 6300 on 5 Ghz wifi can't connect

I am unsure when this started. I definitely could connect to 5 my router's 5 Ghz line over a month ago. (i moved and didn't have internet at the new apartment for a month)

Here is the scenario:
* Thinkpad x230 with Intel Ultimate-N 6300 3x3 AGN
* Can connect without issues to 2.4 Ghz hotspot.
* Can see 5 Ghz hotspots. Cannot connect to it.
* Configurations of the router seems correct. I can connect to the 5Ghz from my phone and my desktop also running arch (broadcom wifi card)
* The intel chip should work. I can connect to the hotspot when I reboot in windows.

wpa_supplicant errors when trying to connect to my hotspot

Any pointers on how to debug this would be helpful. Thanks.

Re: [Solved] Intel 6300 on 5 Ghz wifi can't connect

Thanks for the reply. I have seen that page. I'm unsure what to do with this information though. What are you suggesting?

The router settings should be correct as I mentioned and I'm able to connect on to the ssid using the same hardware on windows.

Re: [Solved] Intel 6300 on 5 Ghz wifi can't connect

Unless there's a bug in the driver/firmware this is from an attempt to eg. using 802.11a to access 802.11n or so (5GHz is used by many protocols)
Is this from a manual connection approach or networkmanager?

Also what does the entire wpa_supplicant output look like? And your configuration/connection steps?

Re: [Solved] Intel 6300 on 5 Ghz wifi can't connect

I do not use a network manager. I am using systemd-networkd + wpa_supplicant.

My wpa_supplicant configuration is basically a list of ssid and passwords in /etc/wpa_supplicant/wpa_supplicant-wlp3s0.conf:

ctrl_interface=/run/wpa_supplicant
ctrl_interface_group=wheel
update_config=1

# normal wifi
network={
     ssid="LAN Before Time"
     psk="password"
}

My network configurations are as follows @ /etc/systemd/networkd/wlp3s0:

[Match]
Name=wlp3s0

[Network]
DHCP=yes

[DHCP]
RouteMetric=20
UseDNS=no

And so I start my networking by starting the following services: systemctl start wpa_supplicant@wlp3s0.service systemd-networkd.service


Output of  journalctl -u wpa_supplicant@wlp3s0.service -f after I restart wpa_supplicant service:

Re: [Solved] Intel 6300 on 5 Ghz wifi can't connect

Assuming wlp3s0 is phy0, compare the outputs of

iw phy0 info
sudo iw wlp3s0 scan

For the scan, oc. the malfunctioning AP is relevant.

Re: [Solved] Intel 6300 on 5 Ghz wifi can't connect

The data rates, but they match.
Try passing

11n_disable=2 swcrypto=1 disable_11ac=true

and if thet doesn't get you anywhere (and since you said it worked before) to downgrade the firmware by moving away newer iwlwifi-6000* files from /usr/lib/firmware
This is voodoo-esque poking around, I don't see why this should fail on that status.

Re: [Solved] Intel 6300 on 5 Ghz wifi can't connect

holy crap. Playing with the "11n_disable" parameter fixes the issue. Turns out, the module was defaulting to "11n_disable=1" for some reason. I just made a file to explicitly set the parameter to 0 and I am able to use 5 Ghz at maximum throughput.

I'll investigate further why this was the default parameter though...

Thanks for your time and help!
