Help installing wifi usb dongle driver

loimp · 7 September 2022 14:04

I have 1 install with KDE and 1 install of Xfce . this request is for Xfce. I bought this-

it came with a disk for Linux.
I’m unfamiliar with the correct way to show you what I have on the disk and what I need help with . basically I need to be walked thru installing the driver. my kernel is 5.15.60-1.
I found a topic , yesterday , for this exact hardware and issue - which is now closed and which I cannot find today. hmmm, search terms . small sample -

#!/bin/bash
# Auto install for 8192cu
# September, 1 2010 v1.0.0, willisTang
# 
# Add make_drv to select chip type
# Novembor, 21 2011 v1.1.0, Jeff Hung

cd driver
Drvfoulder=`ls |grep .tar.gz`
echo "Decompress the driver source tar ball:"
echo "	"$Drvfoulder
tar zxvf $Drvfoulder

            there may be a question of changing the kernel headers?

all help will be greatly appreciated .

just download the driver from aur;
first install headers:
pamac install linux515-headers
install driver:
pamac build 8192cu-dkms
reboot

ok. thanks. that is done but the dongle doesn’t show up in inxi -Fazy. at the moment I’m using an old , old 2.0 dongle as my only way to get internet. no ethernet available. is there more I have to do ? oh! I neglected to reboot .

brahma · 7 September 2022 14:35

so connect the new usb wifi and post output from:
inxi -xxN
lsusb

Tip:

When posting terminal output, copy the output and paste it here, wrapped in three (3) backticks, before AND after the pasted text. Like this:

pasted text

This will just cause it to be rendered like this:

Sed
sollicitudin dolor
eget nisl elit id
condimentum
arcu erat varius
cursus sem quis eros.

Instead of like this:

Sed sollicitudin dolor eget nisl elit id condimentum arcu erat varius cursus sem quis eros.

Thereby increasing legibility thus making it easier for those trying to provide assistance.

brahma · 7 September 2022 14:56

so create this file:
sudo nano /etc/modprobe.d/blacklist.conf
and put there this line:
blacklist rtl8192cu
save the file with ctrl+x and run this:
sudo mkinitcpio -P
reboot and test

Mirdarthos

thanks. I’ll do so

loimp · 7 September 2022 15:17

well, funny thing happened on the way to the forum. the new dongle still doesn’t show up when I plug it into the same usb port. but the old dongle is now showing 90+ to 100% since we did what you suggested - some of the time . it’s still fluctuating down to 70% and probably lower but the signal is much better. I would like to get the new one running . any idea what we can do further ? what output do you need ?

brahma · 7 September 2022 15:23

so we were installing drivers for this one:
ASUSTek USB-N13 802.11n Network Adapter (rev. B1) [Realtek
RTL8192CU]
which was the wrong one … you have nineplus and for that we need the RTL8812BU driver … but we have a problem, the nineplus is not being detected with the lsusb command …
is the nineplus connected to the pc? try different usb port and post again output from:
lsusb

loimp · 7 September 2022 15:41

ok. also I’m at a motel . the router is a good 100 ft. away thru a couple of block walls. the old dongle randomly disconnects etc. .

each time I followed an instruction and restarted I unplugged the old dongle and plugged in the nineplus; gave it a few seconds , enough time to come up but it hasn’t so far.

I just plugged the new dongle into the port that I’ve been using - with no effect and also plugged the old dongle into another port and it works. both are now plugged in . now I’ll do lsusb .

brahma · 7 September 2022 15:43

so now it is detected:

Bus 005 Device 007: ID 0bda:b812 Realtek Semiconductor Corp. RTL88x2bu [AC1200 Techkey]

post again output from:
inxi -xxN
to check if we need to do again some blacklisting

loimp · 7 September 2022 15:46

I think I’m learning a tiny bit. yes. it looks to me like the USB-N13 needs to be blacklisted .

Network:
  Device-1: Realtek RTL8125 2.5GbE vendor: ASUSTeK driver: r8169 v: kernel
    pcie: speed: 5 GT/s lanes: 1 port: f000 bus-ID: 06:00.0 chip-ID: 10ec:8125
  Device-2: ASUSTek USB-N13 802.11n Network Adapter (rev. B1) [Realtek
    RTL8192CU] type: USB driver: rtl8192cu bus-ID: 1-2:4 chip-ID: 0b05:17ab
[me@ailoailo ~]$ ```

or is it just the driver ?

brahma · 7 September 2022 15:49

no it doesnt need to be blacklisted, i wanted to check if the driver for the nineplus needs to be blacklist if there is any provided by the kernel…

so install the driver:
pamac build rtl88x2bu-cilynx-dkms-git
reboot

loimp · 7 September 2022 16:04

Oh, ok I did the last command. lsusb still shows the N13 and rtl8192cu . I unplugged the N13 and lose the wifi with the nineplus plugged in . plug it back in and regain wifi .

I have to step away for about 15 min.

brahma · 7 September 2022 16:08

did you rebooted after you installed the driver?
so keep unplugged the n13 and the AC1200 Techkey plugged in, then reboot and check if you have wifi …
also provide again output from:
lsusb && inxi -xN
while the n13 remains unplugged

loimp · 7 September 2022 16:33

ok. well it’s working . thanks a lot. but now I’m back down to 74%. what the heck ? also I went ahead and plugged them both in and network connections shows them both connected and offering to disconnect from either/both.

I was ecstatic with the 90-100% . did I just waste 28$ ?

brahma · 7 September 2022 16:37

there is a different driver we can try, so remove this one:
pamac remove rtl88x2bu-cilynx-dkms-git
and install this:
pamac build rtl88x2bu-dkms-git
REBOOT
