[SOLVED] connect to network, wifi RTL8192EU, authentication problem

jancici · 2020-01-27 13:43:34

Hi,

I did reinstall archlinux on desktop because hdd failure. When PC is connected to NET by cable everything is working OK.
In one moment I disconnect cable and did try to used usb wifi to connect to my AP and that is not working.

I have this USB:

lsusb
...
Bus 002 Device 007: ID 0bda:818b Realtek Semiconductor Corp. RTL8192EU 802.11b/g/n WLAN Adapter
...

I have also laptop with arch, usually it is connected by cable to the NET. Using wifi is not problem and also others devices are connected to AP without problem. Anyway, I did unplug cable from laptop and plug that usb wifi. I was able to connect to AP and NET, everything works OK.

question is , why I am not able to connect my PC to wifi AP.

here is log during making connection

Have you seen https://wiki.archlinux.org/index.php/Wireless#rtl8xxxu?

If lwfinger's modules don't make any difference then please post back with the output of

systemctl list-unit-files --state=enabled

jancici · 2020-01-28 15:23:56

you saying that I should try to build that module?
a) well, I don't understand how that can help me because IF I plug that usb wifi to laptop where I have same archlinux (kernel) I can connect to wifi AP.
b) my usb wifi is 8192EU but I can see only 8192EE, 8192DU, 8192CU

meanwhile, here is output

Are you sure you used the wifi dongle on the notebook? 'cause they usually come w/ wifi built-in…

Cut out networkmanager. Disable the service and reboot (to get into a clea state) and see whether you can connect w/ wifi-menu.
Reg. the "clean state": do you have a parallel windows installation? https://wiki.archlinux.org/index.php/Du … ibernation

jancici · 2020-01-28 18:03:25

yes, you are correct, I did think that I am using USB dongle but PCI wifi was used, I did check more carefully:
I can see USB and PCI wifi on laptop (in gnome right top corner), both are switch off. Then I switch on only USB and I did get connection, but PCI wifi was used for that => strange. So I did select my wifi under USB list of available networks and NetworkManager could not get connection.

I have only archlinux on PC and laptop.

Please, can you help me with compiling that custom module?

seth · 2020-01-28 20:59:37

https://aur.archlinux.org/packages/8192eu-dkms/

I'd however first try to connect w/o NM, because either it's scanning or the MAC spoofing could interfere here.

jancici · 2020-01-30 10:23:21

So I did install dkms and 8192eu-dkms packages.

thank for this comment
https://aur.archlinux.org/packages/8192 … ent-611252

I did blacklist rtl8xxxu and looks that everything works OK.

thanks for help
