Hi,

OS: Ubuntu 19.10

I have a TP-Link TL-WN8200ND [Realtek RTL8192CU] wireless adapter. When it is connected the green led is on. But after trying to connect to my wifi network I'm getting an "Activation of network connection failed" popup message.

I tried booting from a Live USB with the same result.

I was following this thread: http://forums.debian.net/viewtopic.php?f=30&t=142930

Here the resuts:

netcfg/do_not_use_netplan=true ignored at install time

With people trying (and required) to work from home due to COVID-19, I need to set up a machine dedicated to an OpenVPN bridge (external Windows clients bridged to a simple Windows workgroup -- no WINS or domain controllers) for our very small office. Unfortunately, it appears that any documentation I find has just been relabeled as being for Ubuntu 18.04, because it ALL uses /etc/network/interfaces to set things up. I finally found this:
Quote:
At install time, a user can opt to use ifupdown by preseeding netcfg/do_not_use_netplan=true. This is done by adding the preseed line to the command line when booting the installation media (i.e. at install media boot menu, press F6, type ‘e’, and add to the command line).
In https://netplan.io/faq#how-to-go-back-to-ifupdown but I have been unable to get the installer for 18.04.4 to recognize (or obey?) the setting. I am seeing many comments about netplan not working well (or at all?) with bridging set ups, plus I have yet to encounter even ONE OpenVPN document for 18.04 that uses netplan files, and I am not nearly expert enough (or at all, really) to completely roll my own set up.

I have also read that there are quite a few issues and very tricky bits to trying to remove netplan and roll back to the older network/interfaces system, so if I cannot get the installer to respect the setting to install the old system, it would seem that I must find a 16.04 install just to do what I need.

Please tell me there is a better way.

I'm seeing very inconsistent wired internet behavior - when running a speed test sometimes both up and down are 100mbps. Other times up, down, or both will be <10mbps. The internet will also just randomly drop sometimes.

I'm not really sure where to go from here, any help is appreciated.

[SOLVED] Newbee to linux - can't install usb wifi adapter driver

Hi everyone.

I installed Ubuntu on my Dell desktop and have enjoyed learning something new.

However, not being overly technical have I made a mistake?

I bought a usb wifi adapter from Amazon - but try as I might I can't install the driver that came with it on a CD (RTL88x2BU_WiFi_linux_v5.3.1)

https://www.amazon.co.uk/dp/B07XCMBLBJ/ref=cm_sw_r_apa_i_5Q1FEbCG1EPD2
(Says Linux compatible - but can see it's not in the communities supported device list).

I've extracted the driver to desktop and opened a console in the directory the install.sh lives.

run: "sudo bash install.sh" (as google advised)

It runs for some time.....

then I get: Compile make driver error: 2
Please check error Mesg


They seem to be

Best way to connect through Nord VPN

Hello,

Which way is the best to connect to Nord VPN ?

I found 3 solutions :

1. Install Nord VPN Linux app , pro: Killswitch , con: Disables UFW (in Terminal the message appears that they had to disable it in order to make the right configurations , but that I’m protected through their Firewall , that’s an general issue, found some articles about but no solutions).

2. through Open VPN app

3. through Network manager

Important for me is that no usual connection is possible if the connection to Nord VPN Break off. The app has an Kills witch for that.
And is there any additional thing I had to do at Linux for anonymity? (Except the things which are at Windows too, like Browser Settings and Add-Ons.....)

I am running Ubuntu Desktop 18. I have been unable to connect to the internet via my router. I can ping my local router, but I can't do much of anything else.
Here is what I get with my "route" command:

Hi!

I'm trying Ubuntu 19.10 Live on my Dell Inspirion 5570. I am unable to connect to 5G WiFi network. However, with 2G everything is fine.
I have included journalctl output when trying to connect to 5G WiFi network. Can anyone suggest what to look for? Driver?

Thanks in advance!

[xubuntu] Cannot configure Huawei 3372H dongle to connect to internet

Hello!


I have a Huawei E3372H mobile network usb dongle for connecting to the internet. I am using HiLink mode on another computer (Win 10) and after automatically installing the hilink manager the browser pops up automatically with the 192.168.8.1. After configuring the SIM card profile it works, the light blue indicator on the dongle is constant and I can access the internet. Next, I try plugging the dongle into a Ubuntu desktop 18.04 LTS and it works automatically too.

However, when I try to plug the dongle into a development board with Xubuntu 18.04 LTS, the dongle turns to constant light blue showing that the 4G network is connected but I cannot connect it to the internet. It does not appear as a virtual ethernet device in ifconfig like i would expect it to.

1) lsusb gives 12d1:14dc for this device
2) tried adding in /lib/udev/rules.d/40-usb_modeswitch.rules the line ATTR{idVendor}=="12d1", ATTR{idProduct}=="14dc", RUN +="usb_modeswitch '/%k'" but there is no difference. I think the generic entry for Huawei models already works
3) checked that ModemManager is running too

May I know what else I can do?

Hi there,

I tried to install the package for the RTL8812AU device as apt install RTL8812AU-dkms. It hasn't worked, and I can't select the devise for wireless.

This same device was working under Windows 7.

I ran the wireless troubleshooting script and nothing jumps out at me as the culprit. Here are the results.

ubuntu server 18.04.4 LTS issue with NAT on VBOX

Hi there,
I am new to ubuntu and I am struggling now with virtual box .I have 4 VMs of ubuntu server 18.04.4 LTS
I have set up two Ubuntu servers with NAT in VBOX but one machine gets the address and other one doesn't
then I have two more machines with two adaptors to both machines
first is internal and second is NAT this time NAT is guessing ipv6 from MAC address (that I think) I tried to give manual IP of NAT but the internet doesn't work.

so i have two problems
first is with 2 VMs with NAT what is the way to enable connectivity of one machine to internet

secondly why NAT as second adptor does not connect to internet if ip address is assigned to it (same ip address of NAT)



Thanks

[ubuntu] Stuck with a desktop computer with WIFI but no ethernet cable possible

Hi All!

I really tried my best to do it myself and scroll through post to try to fix the problem but it's been hours and I'm stuck.

So I have an ubuntu 18.04 bionic on HP desktop with Wifi but no possibility to connect an ethernet cable (living in a basement, no access to landlord, they fled the coronavirus) but I have a laptop.
my settings says "no wifi adapter found"

I tried 2 methods :

1) this one
https://askubuntu.com/questions/1152...ing-connection

So I wrote first:

Code:
sudo nano /etc/netplan/*.yaml
and wrote this:
Code:
network:
  version: 2
  renderer: networkd
  ethernets:
    enp2s0f1:
      addresses: [10.0.0.131/24]
      gateway4: 10.0.0.1
      nameservers
        addresses: [10.0.0.1, 8.8.4.4, 8.8.8.8]
      optional: true
  wifis:
    wlp3s0:
      dhcp4: yes
      access-points:
        "network_ssid_name": TELUS666
          password: "inputMyPasswordBetweenTheseBrackets"
NOTE: I didn't change anything else than the 2 last lines with my network name and my password

and I manually downloaded the two packages from my laptop "wireless tools" and "wpas supplicant"
put them on a USB key
and installed them on my desktop with
Code:
sudo dpkg -i thepackage.deb
then I did what he suggest:
Code:
sudo netplan --debug generate
# make config files

Code:
sudo netplan apply
# apply new configuration

Code:
reboot
# reboot and verify proper operation

It didn't worked. Still "no wi-fi adapter found".

Then I came here, found this:

2) https://ubuntuforums.org/showthread.php?t=2214110

With the broadcam series WiFi.
So I run first to purge if I had something installed by mistake:
Code:
sudo apt-get purge bcmwl-kernel-source
Then I ran his command to see what type of broadcam. I have this:
Code:
03:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM43228 802.11a/b/g/n [14e4:4359]
so according to the list I need to get this package:
Code:
bcmwl-kernel-source
went to get the package from here
downloaded the one for 18.04 amd64 (that's my system)
and install on my desktop.

The problem now is that this bcmwl package depend on other packages. like dkms. Which depend on other packages. Etc.
anyway I would like to avoid downloading 100 packages manually, just to get my wi-fi if possible :D

any ideas how to proceed ?

thank you!!!

Hi all,

I need to retype everything as my wifi stopped haha

My wifi is very slow...
Code:
sudo lshw -C network

I tried several stuff:

1)Disable 802.11n
I typed
Code:
sudo rmmod iwlwif
 sudo modprobe iwlwifi 11n_disable=1
got this:
Code:
rmmod: ERROR: Module iwlwif is not currently loaded
I guess this line is for intel, but I have broadcom. is it why I get an error?

2)fixing a bug in debian avahi
with this:
Code:
sudo gedit /etc/nsswitch.conf
and changed a line to this:
Code:
hosts:          files dns
but it didn't work so I undid the change

3)"the chili method"
I ran all lines
Code:
sudo sed -i 's/3/2/' /etc/NetworkManager/conf.d/*
no output but no error either

Code:
sudo iw reg get
I got this
Code:
global
country CA: DFS-FCC
    (2402 - 2472 @ 40), (N/A, 30), (N/A)
    (5150 - 5250 @ 80), (N/A, 23), (N/A), NO-OUTDOOR, AUTO-BW
    (5250 - 5350 @ 80), (N/A, 24), (0 ms), DFS, AUTO-BW
    (5470 - 5600 @ 80), (N/A, 24), (0 ms), DFS
    (5650 - 5730 @ 80), (N/A, 24), (0 ms), DFS
    (5735 - 5835 @ 80), (N/A, 30), (N/A)
so I guess I m ok, it s set to canada

I also went to the settings of my wifi and disabled IPv6.

sometimes my wifi is fine for a dozen of seconds, then get super slow. It s pretty unstable
is it something to do with
Code:
bcmwl-kernel-source
?
Is there another driver I need to install?

Any ideas? thanks for your help!

Ubuntu 18.04.04LTS DHCP server status error

Hi community,

I am experiencing a status error for my isc-dhcp-server on Ubuntu Bionic Beaver. I think it might have to do with the wireless configuration I added in the dhcpd.conf file, although this is coming from the Cisco official webpage you can find here: https://www.cisco.com/c/en/us/suppor...hId-1101475086

It looks fairly straight forward and I cannot find syntax issues in the file (keep in mind I am a complete noob at this), nor can I find out how to actually see where the process gets stuck (which line in the file).

If anyone can help me find out what's the issue or how to troubleshoot this, that would be very much appreciated!

error output:

Cannot access Samba server on NAS

Hi folks,

I just installed Kubuntu 20.04 yesterday. Everything is awesome. Pretty much all of my function keys are supported out of the box, volume, brightness, mic, middle button. It even promotes a BIOS update in Discovery which never happened before. I have no idea how Kubuntu can check for BIOS update. :p

Anyway, The only thing I cannot solve after two-plus hours searching is that I cannot access files stored in my NAS. I use the NAS to stream movies basically. In Windows or other distributions, I just open the file manager, go to the network and the NAS server is right there. I can see the server N5550 in Dolphin->Network, but when I double click on it, it says the connection to n5550.local is interrupted. Any idea how to fix it? I have installed samba and samba-client I even set up an smb server on this laptop following one post :p which obviously not my intention.

A few pictures to help you understand. Thanks in advance.

But cannot connect to it.jpgIt shows in Dolphin.jpgBIOS update in ubuntu.jpg

Streaming from storage drive

I have a new computer withe two hard drives - a smallish SSD for system files and regularly accessed documents and a conventional larger hard drive for storage of (mainly) media files. Ubuntu 19.10 came with a sharing/streaming option which I can use successfully for files on the SSD, but not for files on the storage drive, even though I have added the relevant folders to the list to be shared. These folders are all showing as shared and the storage drive is mounted, but I can't see them on either of my smart TVs.
Anyone got any ideas?
