I had really big ping problems with games, so my friend said that i should get a new network adapter. I got a TP-Link Archer T2U Plus. I installed drivers I found here. It shows up as a device but I cant connect to any networks.

Here`s my lsusb:

I have Ubuntu 20.04

Reference: Ubuntu 18.04 - Ethernet disconnected after suspend

When waking up from 'suspend', the wired Ethernet connection is not working.
In the Network section of Settings it says that the cable is unplugged.
I can manually turn it on with modprobe as described in several answers in the reference post:
sudo lshw -C network (To find the name of the driver. sky2 in my case.)
sudo modprobe -r sky2
sudo modprobe -i sky2

I then placed the full script of the Ubuntu 18.04 reference post inside /lib/systemd/system-sleep and made it executable, but it didn't work in my case (I did change the driver name from r8169 to sky2).

Then I simplify the script to just this and it worked:
#!/bin/bash
modprobe -r sky2
modprobe -i sky2

I would appreciate an expert opinion to know if the simplified script is good enough or if I should expect any bad secondary effect. Thanks!

I upgraded my Wireless Card from Intel Wireless 9560 to AX200.I have Dual Boot Windows OS & Ubuntu 20.10 on my HP Omen.

I updated my wireless driver on my Windows 10 environment.Everything working perfectly.Every time I boot into my Ubuntu 20.10,I have to connect to my hidden Wifi every time.

I tried to see if Ubuntu recognizing the AX200 drive.This is what I found:

    krillavilla@krillavilla-OMN:~$ sudo dmesg | grep iwlw[sudo] password for krillavilla: [    3.259537] iwlwifi 0000:04:00.0: enabling device (0000 -> 0002)[    3.269345] iwlwifi 0000:04:00.0: Direct firmware load for iwlwifi-cc-a0-56.ucode failed with error -2[    3.270894] iwlwifi 0000:04:00.0: api flags index 2 larger than supported by driver[    3.270911] iwlwifi 0000:04:00.0: TLV_FW_FSEQ_VERSION: FSEQ Version: 89.3.35.22[    3.270915] iwlwifi 0000:04:00.0: Found debug destination: EXTERNAL_DRAM[    3.270917] iwlwifi 0000:04:00.0: Found debug configuration: 0[    3.271217] iwlwifi 0000:04:00.0: loaded firmware version 55.d9698065.0 cc-a0-55.ucode op_mode iwlmvm[    3.271333] iwlwifi 0000:04:00.0: Direct firmware load for iwl-debug-yoyo.bin failed with error -2[    3.358293] iwlwifi 0000:04:00.0: Detected Intel(R) Wi-Fi 6 AX200 160MHz, REV=0x340[    3.561857] iwlwifi 0000:04:00.0: base HW address: e0:d4:e8:53:eb:b1[    3.577475] iwlwifi 0000:04:00.0 wlp4s0: renamed from wlan0krillavilla@krillavilla-OMN:~$ lspci -nn | grep Network04:00.0 Network controller [0280]: Intel Corporation Wi-Fi 6 AX200 [8086:2723] (rev 1a)

UPDATEI went to the Intel website to load the driver using the instructionprovided on this link Intel Linux Wireless Driverl

I still get kicked off my Wifi randomly

UPDATEIt's been 4 hours and I did not get kick off my wifi yet.I did some research and found this article Kernel Updatewhich I already have an updated version of the kernel.

krillavilla@krillavilla-OMN:~$ uname -r5.8.0-28-generic

Also, people had reported disabling Fast Boot and secure on Windows 10 OSIntel Fast Boot. I already disable Fast boot startup and my secure BIOS is disabled since I have Windows OS dual boot.

Now, my issue is my throughput on my Windows 10 OS speed test is over 120mbps download speed. On my Ubuntu 20.10, I get a 55mbps download speed.All the other devices connected to my TP-Link AX6000 getting over 200+mpbs download speed. my laptop is the only device that getting less than 200mbps.

Why is that?

UPDATE

I restart my computer and Ubuntu 20.10 didn't connect to my Wifi automatically. I have to go to Network Manager and connect it manually.

UPDATE

Its been several hours and I didn't get kicked off my wifi but I stillhave to connect to it manually after restart or reboot.

I have 4 questions I need help with:

1. Can someone help me resolve this error message:

    [3.484752] iwlwifi 0000:04:00.0: enabling device (0000 -> 0002) [3.498326] iwlwifi 0000:04:00.0: Direct firmware load for iwlwifi-cc-a0-56.ucode failed with error -2

2. Can someone help me figure out why Ubuntu won't connect to my WifiAutomatically after reboot/restart?

3. Can anyone explain to me why my Windows 10 OS has way faster Link speed/throughput than my Ubuntu 20.10? Is there a fix for this issue?

4.Is there a way to install WPA 3 and 802.11ax on my Ubuntu laptop?

I'm new to linux I'm using linux on my laptop but the only problem is that the wifi not working before the laptop was on windows and the wifi working

I think this information can help to find a solution

I recently installed a Broadcom Wi-Fi card in my laptop. There are now 2 Wi-Fi mini PCI cards in the laptop.

The Intel Wi-Fi card works fine (always has). After installing the Broadcom card, I ran Additional Drivers and installed the proprietary drivers for it,but on rebooting both Wi-Fi cards are disabled.

I have also tried running:

sudo apt remove broadcom-sta-dkms bcmwl-kernel-source

and then reinstalling the Broadcom drivers.

Currently I have removed the Broadcom drivers and rebooted. Now the Intel card works OK.

I installed a fresh ubuntu server 20.04. Then I am unable to connect to my home internet wifi. I followed this How to enable wireless on Ubuntu Server 18.04 via CLI?, but isn't helping either. I have attached screenshot of the terminal outputs, please let me know if this is enough.

The screenshots show following outputs:

1. Ubuntu version to confirm (Pic 1)
2. Filename of default yaml file and its content after I changed (Pic 1)
3. output of ip addr show. I used the wlp8s0 in the yaml file (Pic 1)
4. output of netplan generate (Pic 2)
5. output of netplan apply (Pic 3)
6. error outputs when pinging (Pic 4)

What could be going wrong?

Thank you in advance.

I upgraded my server to 16.04 from 14.04, which in turn was upgraded from 12.04, all using the command line do-release-upgrade. This is a server build, with absolutely no GUI. It runs apache2, bind9, nfs, and a few other network-related services. For the most part, nothing was broken in the upgrade... except the network. Now, I have to run

sudo /etc/init.d/networking start

after every reboot to get it to connect to the network. Not very helpful for a server. My guess is that the networking script simply isn't being run on startup; normally, I could fix the issue by running

sudo update-rc.d networking defaults

but the above command just gives an error about being unable to connect to upstart.

What can I do to fix my network?

Edit: The contents of /etc/network/interfaces:

I have two PCs running Linux Mint 20.10. One is my daily workstation and the other is used as a server for Home Assistant. I have installed both the openssh client and server on both PCs and confirmed they are enabled and started. I've checked and the Linux firewalls are not blocking port 22 and my router is allowing connections to 22 on my LAN. When I try to connect from my workstation to the Home Assistant (HA) server with any ssh client, the connection always times out without any connection being made. I am able to ssh from the server to my workstation without any problem.

I have tried using the verbose mode of ssh as well as looking at the auth_logs to see if they might give me a clue on the problem. Neither shows anything about the connection once the "connecting 192.168.1.193" is issued. I can ping the HA server from my workstation without issue. However when I do a traceroute I get nothing but asterisks. Interestingly my Home Assistant instance is running inside VirtualBox bridged to the servers ethernet connection and has it's own IP. When I traceroute to the HA IP address I get the route info, no asterisks.

OS = Ubuntu 18.04 LTSPC = Lenovo Ideapad Y500 (released 2012)Wireless card = Intel Centrino Wireless N2230

I just installed Ubuntu 18.04 LTS on an old Lenovo Ideapad (notebook) model Y500. It works OK, but for WiFi to work, I have to provide these commands in a Terminal:

sudo modprobe -r iwlwifisudo modprobe iwlwifi 11n_disable=1

This works, but only for a little while. If the computer goes to sleep (or is rebooted), I have to give these commands again.

1. I have no clue what these commands do.

2. Whatever these fixes, I would like to make permanent.

3. When this works, WiFi speed is horrible (about 20 Mbps), but wired ethernet speed is wonderful (about 930 Mbps - I have fiber internet).

I have no clue what Ubuntu sees as my WiFi card. If this were Windows, I could look at the Device Manager and see what Windows thought it is (which can be wrong). With Linux, I'm too stupid to figure out what the OS thinks the card is.

Is it possible that Ubuntu is misidentifying my wireless card? If yes, can I fix this (and improve speed) by using a different driver?

So following is my scenario.

I have a domain network and only single machine with Ubuntu. All users are registered on this windows domain.I have no control over domain network it is maintained by someone else. What is happening is the machine with Ubuntu is being continuous thrown off the network cause the user is not of the windows domain. I want to use the existing windows Active Directory or User Directory. I am bad with network terminology and integrate it with Ubuntu.

I have been referring the following guides for the same(Am only allowed to post 2 links):ActiveDirectoryWinbindHowto

Now the issues is steps are written to follow and proceed. But it doesnt explain what each does so i cannot predict what can go wrong after doing this in my case. Moreover I am very poor at Networking and its concept. And I do not understand LDAP and SAMBA configuration.

Is there an easier resource or easy to use automation tools to take care of this on Ubuntu. I refer the following for automated tools:likewiseopenBut again how it does at the back is not explained so I cannot predict what can go wrong and it will be difficult to go back.

So now questions are 1 - Is there a guide that actually explains the steps you are doing ??2 - Is there a safe practice to follow if we take these steps from online for ease of reverting back what has been done?3 - Are there any currently active automated tools available for this kind of stuff in ubuntu?And last but not the least4 - Is this process really this complex??

Any help and direction for proper resource or proper terminology to use for search would be great help.

I have a problem. There is a server. It has two network cards installed.

Logically, one network card (enp4s0) for the Internet.

Second network card (enp2s5) for network users to access the server (server IP: 192.168.1.5).

The problem is my config only works for one network card.

When I change the metrics, only access from the network works, or access to the server from the Internet. I need everything to work in parallel.

Please tell me what is my mistake?

According to the configuration below, I can access the server, both from the Internet and from the local network, but users do not see it (since the metrics for enp4s0 are lower than for enp2s5)

Netplan

network:  ethernets:    enp4s0:      dhcp4: no      addresses: [192.168.0.222/24]      nameservers:        addresses: [1.1.1.1, 2.2.2.2]    routes:      - to: 0.0.0.0/0        via: 192.168.0.1        metric: 1    enp2s5:      dhcp4: no      addresses: [192.168.1.5/24]      routes:        - to: 0.0.0.0/0          via: 192.168.1.1          metric: 2        - to: 0.0.0.0/0          via: 192.168.2.1          metric: 2  version: 2  renderer: networkd          

My GSM modem is attached to ttyUSB2 port but I am not able to access the port for AT commands. When I try to access it I get an error as below:

$ sudo minicomDevice /dev/ttyUSB2 is locked.

the network frequently fails and I would like to monitor the output. I tried to makeshift a command like:

ping www.google.fr | while read pong; do echo "$(date): $pong"; done 1>/dev/null && 2> ~/ping_err.log

but the STDERR is still redirected to STDOUT instead ping_err.log

note: I want only STDERR in the file (not 2>&1)

Thanks!

I have installed on rpi4 8Gb an ubuntu 20.04 server image for rpi4 64Bit

then I have installed ubuntu-desktop

I have problem on wifi and setup this bug

I have disable NetworkManager thinking the pakage have some bug

I have to stay on LTS version 20.04 so if it work on 20.10 I have to wait a backport

I configure netplan to use networkd as renderer.

I future I have to configure vpn.

I have not found maual/help/google on how to change connection.
On NetworkManager I can setup 4 connection for example

1. conn1 using dhcp
2. conn2 using fix IP for test
3. conn3 using wifi
4. con4 using a vpn

then I can choose the connection to use.
close connection 1 ad open connection 2 etc.

How con do this on my configuration using netplan, systemd-networkd?

best regards,
Leonardo

i have two pc and in one of them i have an ubuntu and on another i have an ubuntu that installed virtualbox machine on it.

i want the VM on the second pc be in an separate network and i can communicate to that via first pc.
(for example all devices on the main network are in the 192.168.1.0/24, but i don't want that the VM be in the main network and i want to be able to connect to that, via first machine that is not the host)
if i set the NAT network, i be able to connect from the VM to the first pc, but i want to comminucate from first pc to the VM.
and if i set bridged network, everything is good, but the VM is in the main network, that i don't want like that.

is that possible? maybe i should add an static route in the first pc.

I am trying to copy a pdf file named cvlatex.pdf from my machine to my personal space on a university server. On my machine, the file is located at C:\Users\matte\OneDrive\Desktop\Web Page

If I connect to the server with nrungi@ssh-sissa and I run pwd, it prints /u/n/nrungi/ and if I run ls it prints many directories including public_html which is the one I want to move my pdf in.

I tried with the control scp cvlatex. nrungi@ssh-sissa:/u/n/nrungi/public_html/, but this returns the error message ssh_exchange_identification: Connection closed by remote host. Lost Connection.

I've read that this control should work but I don't understand why it doesn't contain the path to the file on my computer. In fact, in my case it does not work.

What is the right control?

P.S. I'm connecting via ssh by using the program PuTTy on Windows 10.

update:

Probably this is because of NAT, although that might an Ekiga specific problem.

I've tried multiple clients on this machine, cannot get any SIP clients to work for me. On the same network, an Android tablet can call an IP phone, no problem, using free SIP accounts. Also, an IP phone, SPA 942, works fine with anveo. The hardphone worked fine with a free Anveo account, so I upgraded ($5/month or so?) to the paid service.

Why is linphone reporting that port 5060 is in use?

After trying to change the SIP port to 5069:

From the GUI I set NAT and entered my external IP. After switching to ipv6 the GUI showed that the registration failed.

I would prefer to use linphonec, which is the CLI. It's just for chat.

I was able to use the OnSIP web-application to call an ekiga account registered on an Android tablet on the network.

Is there anyway to automatically assign a dynamic IP to a domain (sub-domain) that I own?

I have a domain at A2 Hosting, let's say mysillysites.com and I've created the sub-domain homesvr.mysillysites.com . Now, at home I have a System of Ubuntu server 20.04 and I want to access it from anywhere using a my sub-domain: homesvr.mysillysites.com

Is it possible ?

I can't access a server via ssh from a specific client.

1. server ssh is working fine because I can access it from another clients

2. client machine is working fine because I can access all other servers from it

3. I try to debug using -vvv but I got no response:

josir@casa2:~/bin$ ssh -vvv supervisor@192.168.0.20OpenSSH_7.6p1 Ubuntu-4ubuntu0.3, OpenSSL 1.0.2n  7 Dec 2017debug1: Reading configuration data /home/josir/.ssh/configdebug1: Reading configuration data /etc/ssh/ssh_configdebug1: /etc/ssh/ssh_config line 19: Applying options for *debug2: resolving "192.168.0.20" port 22debug2: ssh_connect_direct: needpriv 0debug1: Connecting to 192.168.0.20 [192.168.0.20] port 22.debug1: connect to address 192.168.0.20 port 22: Connection refusedssh: connect to host 192.168.0.20 port 22: Connection refused

Client (192.168.0.34) and Server (192.168.0.20) are on the same network.

How can I debug to find where the problem is?
