the right "way" for a driver for EDUP wireless USB adapter

[datagueule]

Hi All,

I purchased a wireless USB adapter for my desktop (supposed to work on linux)
But I got a bit lost with the driver installation.

I found on the website (http://www.szedup.com/product-item/wireless-usb-adapter-6dbi-antenna/#tab-id-1)that the model is EP-MS8551. So I could find the driver on the website brand here (http://www.szedup.com/support/driver-download/ep-n8551-driver/).
The driver is a .zip file, so I first search where to copy past the folder, but I realized that might be a bad idea. from the README:


Build Instructions:
====================

1> $tar -xvzf DPB_RT2870_Linux_STA_x.x.x.x.tgz
go to "./DPB_RT2870_Linux_STA_x.x.x.x" directory.

2> In Makefile
set the "MODE = STA" in Makefile and chose the TARGET to Linux by set "TARGET = LINUX"
define the linux kernel source include file path LINUX_SRC
modify to meet your need.

3> In os/linux/config.mk
define the GCC and LD of the target machine
define the compiler flags CFLAGS
modify to meet your need.
** Build for being controlled by NetworkManager or wpa_supplicant wext functions
Please set 'HAS_WPA_SUPPLICANT=y' and 'HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y'.
=> #>cd wpa_supplicant-x.x
=> #>./wpa_supplicant -Dwext -ira0 -c wpa_supplicant.conf -d
** Build for being controlled by WpaSupplicant with Ralink Driver
Please set 'HAS_WPA_SUPPLICANT=y' and 'HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=n'.
=> #>cd wpa_supplicant-0.5.7
=> #>./wpa_supplicant -Dralink -ira0 -c wpa_supplicant.conf -d

4> $make
# compile driver source code
# To fix "error: too few arguments to function ¡¥iwe_stream_add_event"
=> $patch -i os/linux/sta_ioctl.c.patch os/linux/sta_ioctl.c

5> $cp RT2870STA.dat /etc/Wireless/RT2870STA/RT2870STA.dat

6> load driver, go to "os/linux/" directory.
#[kernel 2.4]
# $/sbin/insmod rt2870sta.o
# $/sbin/ifconfig ra0 inet YOUR_IP up

#[kernel 2.6]
# $/sbin/insmod rt2870sta.ko
# $/sbin/ifconfig ra0 inet YOUR_IP up

7> unload driver
$/sbin/ifconfig ra0 down
$/sbin/rmmod rt2870sta

but I m confused here. they say to define the kernel to the LINUX_SRC. But there are a lot of lines in the makefile with that, and I have no idea what to modify and how. That s just point 2. Point 3 I don t know how to define all this. It seems really complicated so I tried to find another source looking for RT2870STA which I understood was the driver name. I found this (https://wiki.debian.org/rt2870sta#supported) but in the list of supported devices, there is no EDUP EP-MS8551. Would it still work?

anybody has an easier way?

thank you!

Please insert the device and help us identify the exact device by running and posting:


lsusb
uname -r

Also, check to see if the probable built-in driver has already loaded:


lsmod | grep -e rt2 -e mt76

If you are having trouble with the built-in driver, or there isn't a built-in driver, you aren't going to fix it by installing this creaky old antique.

Hi again chili! thanks for your help :D

cfg80211 704512 3 wl,mt7601u,mac80211Ahhh! The old "install a Broadcom driver for a Ralink/Mediatek device" technique! It never works, sadly.

Let's remove it:


sudo apt purge bcmwl-kernel-source
sudo modprobe -r wl

Any improvement?

As you can see, the built-in driver mt7601u loaded. Does the wireless not work or not work properly? Please tell us the issue.

May we also see:


dmesg | grep -e wlx -e mt76

Hi Chili!

just for a background, I came from here (https://ubuntuforums.org/showthread.php?t=2439972&p=13944377#post13944377)
:D so my wifi was working but super slow and you told me the driver had an issue, so I got an USB wireless :)

so I purged the bcmwl-kernel but upon
sudo modprobe -r wl I got this:
modprobe: FATAL: Module wl not found.

Try
sudo apt install git dkms
git clone https://github.com/jeremyb31/mt7601u-5.3.git
sudo dkms add mt7601u-5.3
sudo dkms install mt7601u/1.0
Reboot

[datagueule]

thanks!
so my desktop doesn t have an internet connection. But the dkms was already installed with newest version and git also, and I cloned the repo to my laptop, then transfer it to my desktop computer with an USB key

the
sudo dkms add mt7601u-5.3 worked

but
sudo dkms install mt7601u/1.0
said

Error! could not find module source directory.
Directory: /usr/src/mt7601-1.0 does not exist

i tried
sudo dkms install mt7601u-1.0 with a dash

Error! Invalid number of arguments passed.

add -m <module>/<module-version> or
add -m <module> -v <module-version>

[CelticWarrior]

thanks!
so my desktop doesn t have an internet connection.

But it needs* an alternative internet connection to clone the repository. Use an Ethernet cable directly to the router or USB tethering from your phone.


* The alternative is likely above your paycheck, sorry to say.

[datagueule]

forgot to say that I cloned the git repository to my laptop, put it on my usb key, and put it on my desktop computer

also, I unfortunately can t access the router, I'm leaving in the basement of my landlords who fled the coronavirus! but I have a big homework for my deep learning class so I unfortunately need internet on my desktop computer :D a nice alternative would be buying my own house and my router, I think I ll go also with two RTX 2080 to run my model if I could haha :D

[datagueule]

Anybody has a solution? I have a presentation tonight and I really need internet :(

thank you :D

[CelticWarrior]

You should cd into the folder then run the commands.

[chili555]

put it on my usb key, and put it on my desktop computerWhere did you put it when you copied it over from the USB key? Your desktop? If so, then:


cd Desktop

Confirm that the file is there:


ls

It should show up as mt7601u-5.3. If so, proceed with the steps Jeremy posted:


sudo dkms add mt7601u-5.3
sudo dkms install mt7601u/1.0Post back any errors.

[datagueule]

Hi !

thanks for your help!

so I pasted it into the /home, and from there I ran Jeremy stuff but it didn t worked. I went into the folder mt7601u-5.3. and ran the command again and it did worked ! I m not sure why, because it seemed more logic to run the command on the /home.
it seems that internet is running fine and is stable. I cross fingers that it stays like this!

thanks again
