I can view 5ghz networks but can't connect

jayant · 2021-11-27 17:29:20

So I have an Archer T2U nano and I am using the drivers from [https://github.com/aircrack-ng/rtl8812au] Aircrack-ng It can discover the 5ghz networks but can't connect to them.

We don't even know what chip that is because you only named a brand and TP-Link has a habit of using different chips in different generations under the same label…

What Seth said + the output of lspci

jayant · 2021-11-28 05:07:44

Well doesn't the driver tell the chip is rtl8812au??

here is the output of lspci

Because it's not

Bus 002 Device 007: ID 2357:011e TP-Link AC600 wireless Realtek RTL8811AU [Archer T2U Nano]

The drivers cover a whole group/family of chips w/ a similar interface.

Now we still need some actual data on the incident.
Eg, idk… oh yeah - maybe a system journal covering the failed attempt to connect to a 5GHz network. Errors from the tool you use (iwd/wpa_supplicant).
Stuff like that might be helpful…

No, it doesn't.
The same driver is used for multiple chipsets...

jayant · 2021-11-28 09:06:46

Oh I didn't know that sorry.

When I try to connect with wifi-menu it throws error

See "systemctl status "netctl@wlan0\\x2dbelkin\\x2d5G.service"" and "journalctl -xeu "netctl@wlan0\\x2dbelkin\\x2d5G.service"" for details.

And when I do systemctl status "netctl@wlan0\\x2dbelkin\\x2d5G.service" it gives me

That's not helpful.

sudo journalctl -b | curl -F 'f:1=<-' ix.io

Make sure you've attempted to connect to the 5GHz AP during this boot.

But why am I able to connect to 2.4ghz wifi connections but not 5ghz?

seth · 2021-11-28 18:03:04

The password for the 2.4GHz AP isn't necessarily the same as that for the 5GHz AP.
Check the AP settings.

If you want to make sure that this isn't some weird NM bug, stop the NetworkManager service and try to connect w/ wifi-menu.
But chances are that you're simply providing the wrong password.

jayant · 2021-11-29 01:57:36

Well no it is not the wrong password, I can connect to the network on windows. I tried using wifi-menu but it just won't scan any networks

seth · 2021-11-29 07:57:42

I tried using wifi-menu but it just won't scan any networks

… did you stop networkmanager before? How?

I can connect to the network on windows.

3rd link below. Mandatory.

jayant · 2021-11-29 17:02:03

systemctl disable networkmanager
systemctl stop networkmanager

seth · 2021-11-29 20:46:38

And did you get any errors for that? The service is CamelCase, NetworkManager and you'll require root privilegues for that action.
Let's see where you're at:

find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -f

Also: did you check the link in my signature by now?

jayant · 2021-11-30 03:07:58

Yea I turned off fast boot.

So if I turn off NetworkManager wifi-menu just throws aborted, and If I have NetworkManager turned on it will scan the networks but I still can't connect to it...
