Lots of problems with Xubuntu and wireless network

ondoho · 02-04-2016, 12:03 PM

it is true what they say about wicd & networkmanager.
i hope installing, then uninstalling wicd hasn't damaged networkmanagers functionality in any way.

in any case. try to plug the wifi adapter straight into the computer, not the usb hub.

reboot.

maybe it helps already.

post the info requested by me again. you can replace the "lspci ..." command with this one:

Code:

sudo lsusb -v

Mi wireless card is dead now in Xubuntu. It does not work at all, and it does not work when I unplug it and plug it again neither. Like when you do not have the drivers installed in Windows.
In Windows 10 works perfectly at the moment.

Your code, here you go:

https://drive.google.com/file/d/0Bzl...ew?usp=sharing

Had to upload the code to drive because it was too long for the forum.

Thanks a lot, you dont really know how grateful I am.

Hey, I found out something that could light up the problem a little bit.

Code:

carlos@carlos-System-Product-Name:~$ cd /var/crash
carlos@carlos-System-Product-Name:/var/crash$ ls
rtl8192cu-tjp-dkms.0.crash  _usr_sbin_NetworkManager.0.crash

Regards

that is your code, not mine.

anyhow, is this the output from all the commands i requested earlier, plus lspci replaced by "lsusb -v"?

please post it again, and this time include the command itself.
post the output for each command inside it's own code brackets: [code] ... code goes here ... [/code]
you CAN post it all here.

in any case, i was able to glean this information so far:

Code:

idVendor           0x0bda Realtek Semiconductor Corp.
idProduct          0x8179 RTL8188EUS 802.11n Wireless Network Adapter

so your system recognizes the adaptor.
based on this info you can already start searching your distro's wiki (realtek wireless howto).

please also post the output of

Code:

lsmod|grep rtl

in that word document you posted, i also saw some mention of "connman" and "dnsmasq" floating by - did you install even more networking software than the already mentioned?
it will get increasingly difficult to recover from all the conflicting configurations; you might want to consider reinstalling, next time consulting your $DISTROs wiki before blindly installing things.

The problem is that I cannot post ALL the code here because it exceeds the character limit and it will not let me.

Code:

carlos@carlos-System-Product-Name:~$ uname -rv
4.2.0-27-generic #32-Ubuntu SMP Fri Jan 22 04:49:08 UTC 2016

Code:

carlos@carlos-System-Product-Name:~$ lspci -knn | grep -EiA2 net
02:00.0 Ethernet controller [0200]: Qualcomm Atheros AR8151 v2.0 Gigabit Ethernet [1969:1083] (rev c0)
	Subsystem: ASUSTeK Computer Inc. Device [1043:83fe]
	Kernel driver in use: atl1c

Code:

carlos@carlos-System-Product-Name:~$ sudo rfkill list

This one did not return anything.

Code:

carlos@carlos-System-Product-Name:~$ lsmod|grep rtl

This one did not return anything, neither.

lsusb code: https://drive.google.com/file/d/0Bzl...ew?usp=sharing
dmesg code: https://drive.google.com/file/d/0Bzl...ew?usp=sharing

Also, I did not install anything apart from Wicd.

Everytime I start Linux it shows me 3 messages saying there was a problem with a program, as well.

Thank you a lot.

P.S.: Ubuntu wiki says nothing about realtek wireless, only wired connection drivers and stuff.

EDIT: Found out that the driver is not loading automatically, doing this

Code:

 sudo modprobe r8188eu

and re-plugging the adaptor made my internet work, but in the same conditions as before (null signal and slow connection).

related?

 sudo modprobe r8188eu

shouldn't that be rtl8188eu?

anyhow, i did some searching for you. seems you're not the only one having problems with this series of realtek wifi dongles, although i could not find your exact model number (rtl8188eus).
have a good look at these:
https://cse.google.com/cse?cx=003883...188&gsc.page=1
https://github.com/search?utf8=%E2%9...=searchresults
https://wiki.archlinux.org/index.php...tion#rtl8188eu

edit:
i'm pretty sure that the realtek drivers also need firmware, and that, too, has to be the correct version.

HHalo6 · 02-09-2016, 03:26 PM

Pretty sure it works with "r8188eu", I do it every time I start Linux.

Anyway, got this https://github.com/mpthompson/rtl8188eu . Can you help me on how to install it? I am very very lost... (it is a .zip file).

(In some webpages it says I have to install something called Gib...?)

Thanks again for taking your time to teach me.

EDIT: Look, this is what I get when I try to type rtl8188eu...

Code:

carlos@carlos-System-Product-Name:~$ sudo modprobe rtl8188eu
[sudo] password for carlos: 
modprobe: FATAL: Module rtl8188eu not found.

Maybe that's the reason why it does not work and installing the file I linked before it works at last?

i don't think so - it's named close enough to the actual device name.
more likely some recent changes in ubuntu development that don't reflect in those web pages quoted.

in any case, what you got from github, first you have to unzip it, then open a terminal inside the unzipped folder and simply type

Code:

make

or

Code:

make clean

and if that doesn't throw any errors:

Code:

sudo make install

if it DOES throw errors, please post the COMPLETE output here.

HHalo6 · 02-10-2016, 04:48 PM

Make threw an error, make clean did not. Make install did. Anyway, I'm posting all of it here:

Code:

Bold parts say:

Code:

make[1]: *** /home/mike/Kubits/linux: No existe el archivo o el directorio.  Alto.

"File or directory does not exist. Stop"

Code:

install: falta el operando archivo de destino después de «8188eu.ko»
Pruebe 'install --help' para más información.

Here it says something like "destination file after <<8188eu.ko>> missing. Try install --help for more information"

Doing install --help I realised I need something like a destination folder in the "sudo make install" command. Where should I put it and how? Thanks a lot.

ondoho · 02-11-2016, 10:51 PM

looks like a badly or unmaintained github repo, or one set up only for the maintainer's personal purposes. sorry about that.

This info may be of help.

0x8179
Chip Number:
RTL8188E
Chip Description:
IEEE 802.11b/g/n Single-Chip WiFi Chip

Mint Community has this tutorial which includes an updated driver version:

HHalo6 · 02-15-2016, 03:38 PM

Hey, did it and I still have the same problem. If I start windows, then restart and then start linux, it won't work until I write "sudo modprobe 8188eu" on a terminal and replug the adaptor. If I do that AND then restart and choose linux again, it will work and detect signal and everything fine... BUT i have to restart twice to do so. Windows works fine for now...

Thanks, anyway. But I still need help I guess... this is driving me crazy.
