Qualcomm Atheros QCA9377 keeps dropping connection in Ubuntu 18.04

Hello,

I have a wifi connection dropping problem on my Asus vivobook x542uq. There is dual boot in my pc (windows 10 and ubuntu 18.04). In windows 10 the wifi-connection is fine. But when i boot in ubuntu within one minute the connection drops.
I've tried changing my router bandwidth auto to 20MHz and also the channel to 9 as per this post https://ubuntuforums.org/showthread.php?t=2414770 and i've tried this link also https://ubuntuforums.org/showthread.php?t=2355396 but no help.

This is my wireless_info file link : https://pastebin.com/7pwrzZMt

And I forgot to tell that if i want to reboot my computer it takes so much time. So, I just [force] shut down.


It would be really great if anyone help me out from this annoying situation.

-Thanks

does Ubuntu support 160 MHz WiFi channels?

$

I ask because my Intel Wireless-AC 9560 PCIe (in a Lenovo T490) only reports 866 Mbps @ 5 GHz and 144 Mbps @ 2.4 GHz; yet, the Intel 9560 specs say that it can support 2x the WiFi legacy -AC (1.73 Gbps) "when using 160 MHz channels".

My router specs specify the transmission rate as: 1900Mbps(5GHz: Up to 1300Mbps, 2.4GHz: Up to 600Mbps).

Apparently, using 160 MHz channels, in addition to 80 MHz channels, is how the new WiFi 6 speeds are implemented/accomplished.

Thanks in advance for whatever insights ...

[ubuntu] Ubuntu 20.04 LTS unable to browse smb share?

$

Hope in the correct area Desktop install problem with network access to files.

I have just done a new install of Ubuntru 20.04 LTS on this machine, being slightly more powerful then my others, I have a couple of oldermachines one with Suse and one with Ubuntu 18.04. On my network I have an old RaspPi running samba shares from a hard disk so basically a network share.

I have followed the help pages in trying to browse for the shares with no success. i.e.
Open the Files application from the Activities overview, and click Other Locations in the sidebar. The file manager will find any computers on your local area network that advertise their ability to serve files

I can see another linux device one of the Pluto SDR's and an icon for Wndows network, clicking on this says it is empty.

I know the location from Ubuntu 18.04 as smb://192.168.1.104/adrian as a valid share, if I try to enter this into the server location.

I get an error of Unable to access location failed to retrieve the share list from server: Software caused connection abort.

I do not appear to have installed samba on Ubuntu 18.04 as if I type samba at the command prompt or smb etc it suggests i install it.

UFW is not running so I believe a firewall issue is not the cause, but I am lost and hope someone can point me in the correct direction to get access to the NFS.

Cheers

Adrian

Hi all,

Does anyone know the command to install TACACS+ on Ubuntu Server 20.04? Most sites suggest to use

Code:

apt-get install tacacs+
This does not work, I get the following:

Code:

root@optplex-780:/etc# apt-get install tacacs+
Reading package lists... Done
Building dependency tree     
Reading state information... Done
E: Unable to locate package tacacs
root@optplex-780:/etc#

Computer has access to the internet and I've refreshed the apt package lists.

Cheers.

WiFi primary/secondary connection idea

$

Feature request (networking):
In the WiFi settings you should be able to set a primary and secondary connection. If the primary goes down, the secondary will be connected to. During the connection to the secondary -- the primary connection will continually be tested at regular intervals and as soon as it is back online... the connection automatically switches back to primary. (Notifications should take place whenever a switch occurs)

E.g scenario:
Say your primary broadband connection is having outages. Then the secondary hot spot connection will be connected to and once the broadband comes online again it will be switch to (to save you money on wireless data).
It could even be customisable (ie switching to primary could be automatic but switching to secondary manual etc)

Atheros AR9271 suddenly stopped working in Ubuntu 16.04

Hi,

WiFi on our desktop has suddenly stopped working. It uses an Atheros AR9271 USB dongle, which shows up when lsusb is run, but no networks are visible in network-manager. There is also no "Enable wireless" option in network-manager. The dongle works fine in other computers.

Everything is up-to-date, as far as I can tell.

Any advice?

[ubuntu] Error adding broadcom drivers in Ubuntu 20.04 (usb installation)

Hi there!

I'm having some trouble to configure the wifi in ubuntu. I've installed ubuntu 20.04 in a 32 gb pendrive on a macbook air. Everything works fine, except I haven't been able to set the wifi properly.

I tried to add the driver from the ISO as well as downloaded and install the broadcom drivers. I've been following some tips on the Internet (it seems a common issue), but I haven't been able to fix the issue so far.

This is the error message I'm getting:

[xubuntu] How to make Wifi working on Inspiron 1501


[ubuntu] How do I get my Network (and settings) back in 20.04?

$

0
I have lost my network connections (Ethernet, WiFi and Bluetooth) on Ubuntu 20.04. I don't know what I did to lose them, but after a reboot, they had gone. There is no network icon in the system tray and in settings, there is no setting for WiFi and no connections in the network submenu.

I can boot from a Live USB image and everything works well.

So, from another answer I found, I backed up, then copied the netplanner, and NetworkManager files and directories from the Live USB to my computer. Rebooted into the "normal" Ubuntu environment and still nothing.

I ran sudo
Code:

lshw -C network
and the output is:

Code:

My NetworkManager.conf file is:
Code:

[main]
plugins=ifupdown,keyfile

[ifupdown]
managed=false

[device]
wifi.scan-rand-mac-address=no

and my 01-network-manager-all.yaml file is:

Code:

# Let NetworkManager manage all devices on this system
network:
  version: 2
  renderer: NetworkManager
Using sudo nmcli gives:
lo: unmanaged
        "lo"
        loopback (unknown), 00:00:00:00:00:00, sw, mtu 65536

Use "nmcli device show" to get complete information about known devices and
"nmcli connection show" to get an overview on active connection profiles.

Consult nmcli(1) and nmcli-examples(7) manual pages for complete usage details.

I don't have ifconfig (net-tools) installed.

Running
Code:

nm-applet
brings up a greyed out system tray icon, but when I click that, the window that opens (showing the connections) is empty.

Any help is greatly appreciated.

WiFi adapter stops responding randomly. Need help!

$

Dear All,
I have a problem with my trusted Asus UX305F laptop. On recent Ubuntu versions (starting from 2020) my WiFi stops working randomly: connection got lost, no wireless networks are visible. If I disable wireless or reload NetworkManager it says "no WiFi available" i.e. the adapter doesn't work any more. When I reload kernel networking modules no errors are reported but WiFi doesn't work.

The problem got solved only after reboot (until it happens randomly again).

I can't figure out if this is software or hardware problem (the laptop is not new after all).

I tried many things suggested in similar topic but none of them produce anything useful. The problem happens on different versions of kernels and firmware. Upgrades or downgrades doesn't fix it.

Could somebody point me to the step-by-step instruction of testing my WiFi hardware?

[server] No ping only with Windows, but it works with Ubuntu (Dual boot)

I have three PCs with Dual boot Win10Pro and Xubuntu 18/20
I then have a Raspberry Pi4 with Ubuntu Server 20.04.


Two PCs have two network cards and Wi-Fi. A PC has a network card and Wi-Fi.
All connections are active.


If from a PC in Windows I PING the other two I can get the address of all the cards and all the Wi-Fi.
And I can get the addresses whether the other two PCs are in Windows or if they are in Xubuntu.
So PING works, both in Windows and in Xubuntu.


On the Raspberry then things change.
If the PCs are on Windows I can't ping.
If the PCs are in Xubuntu, pinging works.


I checked, the IP addresses are correct and, as I said above, in Windows PING work.
It is only from Raspberry that I cannot ping on Windows PC.

Iwlwifi fails to find network adapter on Ubuntu 18.04

Hi folks,

I'll try to post the relevant information - please let me know if I missed something important. When I open up Wifi in settings it says No Wifi Adapter found. I've tried a couple different firmwares, two kernels and countless reboots - any advice would be much appreciated.
Ubuntu 18.04
Kernel 5.3.0-62-generic
Hardware: Dell Inspiron 7786 with Intel Wireless device Intel Corporation Device 9df0 (rev 30)

Iwlwifi fails to find network adapter, so no wireless network capabilities in Ubuntu 18.04. This fails with kernel 5.3.* and kernel 5.4.*.

[ubuntu] network lost during sleep

Hi,
from time to time (but really often), my PC loses its ethernet network while in sleep (not deep sleep, just standard)
at waking up, it shows: impossible to activate the network, and network manager displays a 10 Mb connexion (on my 1000 Mb network card)
The only way to get the network back is to unplug the network cable, wait for the network icon to disappear, and replug the cable....then the network activates with 1000 Mb connexion

I can't find the solution to this issue who ruin my life for several months
Any ideas?

[ubuntu] Bluetooth not working

Hi,

I have a Lenovo Z570 with Ubuntu 16.04 and, while wireless works, Bluetooth doesn't.

The manufacturer's guide shows the following Bluetooth specs:

"BT2.1 + EDR CyberTan/USI module"

and

"Bluetooth card, BT2.1 + EDR, Fcn BCM92070 BT2.1 EDR Flash U NB".

the Bluetooth manager says "No Bluetooth adapters found".

Thanks for your help.

p.s. below is the output of diagnostic commands requested on a similar thread:

Netplan/subiquity config first active link?

$

0
I have a bunch of identical desktops that I am trying to generate configurations. I see with Netplan I can match based on name, driver, and a couple other things. Is there a way to test/match if the link is active? I know each one will have only one Ethernet link active, and that is the one I want to configure. Any hints or tips are appreciated.

Thanks in advance.

not able to connect to the internet with broadband cable kubuntu 20.04

I was previously using ubuntu 18.04 as I could not upgrade to 20.04 because of low RAM, I installed Kubuntu 20.04 instead. Now previously I was able to connect to the internet by inserting the broadband cable directly into the laptop without doing anything but now I am not able to connect to the internet through cable in Kubuntu 20.04, with notifiaction like IP configuration unavailable, enp48s0 etc I tried reinstalling network manager. I tried the methods https://askubuntu.com/questions/8828...ce-not-managed without any success. Kindly help.

[ubuntu] wpa_supplicant: 'ctrl_iface exists and seems to be in use - cannot override it'

$

Ubuntu server 20.04 LTS

The error message
Code:

ctrl_iface exists and seems to be in use - cannot override it
Delete '/run/wpa_supplicant/wlx00c0caaa58da' manually if it is not used anymore
Failed to initialize control interface '/run/wpa_supplicant'.
You may have another wpa_supplicant process already running or the file was left by an unclean termination of wpa_supplicant in which case you will need to manually remove this file before starting wpa_supplicant again.

Somehow it seems to be I'm running two instances of wpa_supplicant?

Some information:
Code:

$ cat /etc/network/interfaces:
/etc/network/interfaces: No such file or directory
$ cat /etc/wpa_supplicant/wpa_supplicant.conf
/etc/wpa_supplicant/wpa_supplicant.conf: No such file or directory
$ cat /etc/conf.d/net
/etc/conf.d/net: No such file or directory

(The above is to show that I didn't define any of those files)

My netplan config file (I have only one file in the directory '/etc/netplan'):
Code:

network:
    version: 2
    renderer: networkd
    ethernets:
        eth0:
            dhcp4: true
            optional: true
    wifis:
        wlx00c0caaa58da:
            dhcp4: true
            optional: true
            access-points:
                "TelenetWiFree":
                    auth:
                        key-management: eap
                        method: peap
                        identity: xxxxxxxxxxxxxx
                        password: xxxxxxxxxxxxxx
                        phase2-auth: MSCHAPV2

"sudo netplan generate" just works fine without any error and "sudo netplan apply" seems to work just fine. The odd thing is: once booted, I can run netplan apply all I want, the error never shows up in my logs.

What I did so far:
  • I removed the file manually as the error message suggests, but it persists
  • I check this forums, but most posts are from before 2016 and most solutions are about some typo in commands like "wpa_supplicant -B -i wlan0 -c<(wpa_passphrase internet password) && dhcpcd wlan0" or about running wpa_supplicant as a daemon... all of which don't seem to apply, since I do none of that, at least: not that I know of

My main question
  • If somebody knows the answer as to why this happens, I'd be happy to know
  • But another question I have is: in this one I don't even know where to begin debugging this? How would I go about pinpointing this problem? There seem to be mechanisms in play I don't understand yet and I'd be interested to know what they are.

[ubuntu] Vpn ubuntu 18.04 only connects once

$

Hi everybody I have recently started using my Ubuntu machine for work (yay I am a c# developer and love the fact that I can work in Ubuntu now) I have everything set up except for the vpn I need for some operations. I am able to work 80% without it. I am attempting to connect to an Azure virtual gateway and I have followed this to get it set up. It does work but only once. I have a url that requires me to go through the vpn for access and when I set it up initially I can connect. If I turn the vpn off and then back on again it does not work and I get a dns error. If I close and then re-open the browser it again works but again only once. closing and re-opening a second time does not work with the dns error.

I am a long time linux user but nowhere near as geeky on it as I used to be so let me know what information you want from me please.

The tunnel type is IKEv2 and SSTP (SSL).

There cannot be much wrong as I do connect just not consistently. Not sure if it makes a difference but I do have the ubuntu-studio packages installed (including the real time kernel I think.)

[edit]
Been looking through var/log/syslog and found this:

Code:

Does this help anyone trouble shoot for me?

[edit]
Have been investigating today but not much furthrt forward. I do connect to my test page occasionally but not consistently. After checking through the instructions above I realised that the gui version of configuring strongswan did not create config properly (which I find confusing as it has connected) so I foolowed the cli version of the instructions. If I run ipsec up dv0_vnet everythign looks ok

Code:

but when I then turn the vpn on through the network manager I still cannot browse to the page.

help need with a dns server bind9 preferably

$

After several fails I am not even sure if a DNS server does what I used to believe that does.
I have an small network. One of the machines connected is a server (a desktop 20.04 ubuntu really). I have a private website running on that server. The problem is the users needs to enter the server ip at their browsers to see the website. I tried to install a DNS server called BIND9 on that server thinking to make things easy for visitors so they can enter a normal url instead of the server ip.
After several tries and fails doubts increased.
I follow the next tutorial in order to install BIND9

https://www.linuxbabe.com/ubuntu/set...tu-20-04-bind9

beside that did not work there is a section almost at the end
Setting Default DNS Resolver on Client Computers

What ???? do I need to configure the client computers in order to make that works ??? I can not touch the visitors computers so if I need to do something like that I am sure that will not work.

Like I said I need to change an IP address for a name to access a website. That is all. Any help is welcomed and even if you know an easier software to do that I will take that.

thanks a lot in advance and any help is welcomed

Referring to https://ubuntuforums.org/showthread.php?t=2397677, the Linux guru at work just helped me out of a pinch and has some additional notes on how to compile the driver to get these cards working in Ubuntu.

Code:

STEPS TO BUILD AND INSTALL TEHUTI TN9710P DRIVER
07/29/2020


-- install the card in the chassis, then power on


-- update and upgrade the system
# apt update
# apt -y upgrade
# reboot


-- verify the card is visisble to the os
# lspci


-- prepare Ubuntu for the module build
# apt install module-assistant
# m-a prepare


-- download the driver tgz from Tehuti
http://www.tehutinetworks.net/?t=drivers&L1=8&L2=12&L3=26&L4=0&L5=0&L6=0&L7=0&sent=true


-- explode the tgz file
# tar -xvpf tn40xx-0.3.6.17.3.tgz


-- read the "Readme" file in the "tn40xx-0.3.6.17.3" build dir


-- check the card version and find that the card is the TN9710P and requires the Marvell PHY hdr
# lspci | egrep "TN"


-- search around the forums and hints and notes until you find someone that posts a link to the
  required .hdr file of "x3310fw_0_3_4_0_9445.hdr".  I found it here...
https://www.gitmemory.com/issue/acooks/tn40xx-driver/3/474259259


-- unzip the downloaded file
# gunzip x3310fw_0_3_4_0_9445.hdr.gz


-- get the file into the "tn40xx-0.3.6.17.3" directory
# cp x3310fw_0_3_4_0_9445.hdr tn40xx-0.3.6.17.3/.


-- build and install
# cd tn40xx-0.3.6.17.3
# make clean
# make all
# make install


-- kick off a rebuild of initramfs
# update-initramfs -u -k `uname -r`


-- test the module (note that the full path will very with kernel - use "find" worst case)
# insmod /lib/modules/4.15.0-112-generic/kernel/drivers/net/tehuti/tn40xx.ko
# lsmod | egrep tn


-- check that the network looks good now
# ifconfig -a
# ethtool DEVICENAME


-- verify that device is present on reboot
# reboot


-- check that the network looks good now
# ifconfig -a
# ethtool DEVICENAME
