Hi.
I just bought Netis WF2160 usb dongle network adapter. I am unable to connect to any of the wifi hotspots I have. The adapter works fine for them on Windows 10 on the same machine.
Please help me troubleshooting the issue.
I had to switch from the previous usb dongle adapter I used because I started experiencing connection drops on both OS on my machine.
Does the network interface show up? Run inxi -naz and report back with the results.
I see that is based on the Realtek8811CU, looks like you need this driver:
Or How to Install RTL8811CU USB WiFi Dongle on Linux - Fastoe
su
sudo apt-get update
sudo apt-get install git
yast2 -i kernel-source
git clone https://github.com/fastoe/RTL8811CU.git
cd RTL8811CU
make
sudo make install
sudo reboot
– maybe
su
zypper up
zypper in git
git clone https://github.com/fastoe/RTL8811CU.git
cd RTL8811CU
make
sudo make install
sudo reboot
assuming you have installed needed packages:
zypper info -t pattern devel_kernel
Better is to wait for
inxi -naz
before compiling by yourself.
Because of the ID of the Chip.
Here is the output when my new dongle is plugged in
➜ ~ inxi -naz

Also I have another problem:
When I start my PC before grub loads I get the following error:
error: ../../grub-core/disk/efi/efidisk.c:615:failure reading sector exfefc from `hd0`
It disappears and proceeds to the usual grub boot selection window once I unplug my dongle.
I also should mention that the dongle also functions weirdly for my Windows 10 and the Android phone I use as the hotspot. It seems to only happen when I use this specific phone, because the dongle works fine with my friend’s Iphone hotspot. At the same time my phone works fine for other computers. I experience connection breaks or sometimes only certain websites function (e.g. Google but not any other website). Also at the time when the breaks start to happen the Internet in some apps on my phone becomes inaccessible also. P.S. as I am typing this I am successfully able to browse the Opensuse forum and post here, but any other website is inaccessible for me in other web browser tabs.
I started to experience almost identical symptoms a week ago on my OpenSuse, so I decided to switch my old usb wifi adpter dongle.
Switch them to Wlan Mode:
usb_modeswitch -KW -v 0bda -p 1a2b
It looks like it has changed since my last reboot:
➜ ~ inxi -naz

I used the new parameters, but it looks like the device is recognized properly now. Still no success accessing the Internet:

Is this the same as before, now only in Wlan Mode?
If yes, use NetworkManager to configure.
This is not my command:

It looks like it.
Now I try to use Network Manager to no avail

In essence, it scans the network and sees the available wifi connections, including mine. However, it doesn’t connect to it.
I think it has already changed to WLAN mode. I tried your command, just in case:
➜ ~ sudo usb_modeswitch -KW -v 0bda -p 1a2b

Does this produce the same error?
nmcli device wifi connect 0E:AA:BD:B1:AF:94 password "MyPassword"
Yes, it’s the same
Yeah, it’s the same
Does anyone think the problem may be related specifically to my Xiaomi Redmi Note phone?
Is it viable for you to test by trying to connect to another Wi-Fi network eg public library or cafe etc?
You can watch the association process in a terminal using
sudo journalctl -fu NetworkManagerI wasn’t able to connect to my friend’s Iphone hotspot with this dongle. It is difficult to test it elsewhere as it’s a desktop PC.
You are using Leap 15.6.
The Module (driver) you are using is very new to Kernel 6.4 in Leap 15.6.
So you could do:
Use a new kernel from kernel:backports:stable
or
try the rtl8821cu Module from here:
https://download.opensuse.org/repositories/home:/Sauerland:/hardware/openSUSE_Leap_15.6/
When you use this Module, you have to blacklist rtw88_usb and blacklist rtw88_8821cu
echo 'blacklist rtw88_usb' >> /etc/modprobe.d/rtw88.conf
echo 'blacklist rtw88_8821cu' >> /etc/modprobe.d/rtw88.conf
