Very much a noob but I am trying to get this wireless wi-fi adapter to work on an old computer my sister uses. Old wireless wifi adapter was an ASUS but it died. Any step by step help would be appreciated. I have computer on a wired connection currently. Thanks.

The problem

Wifi seems to connect fine after system bootup or reboot, but if I suspend my computer (which is a laptop, so this is happening whenever I close the laptop lid), when the computer wakes, wifi indefinitely attempts to connect and fails.

Details

I've been trying to diagnose what's going on primarily by looking at the output ofjournalctl --follow.

Here's the bad version (where authentication seems to time out every time), which I recorded after opening my laptop from a suspended state:

And here's the good version, which I recorded after rebooting my laptop with the wifi disabled and then enabling it after I'd started journalctl --follow:

As you can see, in the second example, it seems like the network connection sets up just fine. Both attempts (good & bad) are using Ubuntu 19.10's wifi set up straight out of the box. It looks like authentication times out in the bad example, but I don't know why that would be happening or how to fix it.

Things I've Tried

I've tried restarting the network manager with sudo systemctl restart network-manager -- that didn't help.

I've tried setting wifi.powersave = 2 in /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf as suggested here.

Lastly, I should say that my previous setup was Ubuntu 16.04 (which I ran XFCE and I think some of the Xubuntu packages on top of) on this same machine, and I don't think I ever had the same problem there.

I have an issue when configuring a second nic for my ubuntu server. Look at this:

root@ubuntubox01:~# lshw -short | grep network/0/100/15/0          ens160      network    VMXNET3 Ethernet Controller/0/100/16/0          ens192      network    VMXNET3 Ethernet Controller

When I look at the IP Addresses:

root@ubuntubox01:~# ip addr sh1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00inet 127.0.0.1/8 scope host lo   valid_lft forever preferred_lft foreverinet6 ::1/128 scope host    valid_lft forever preferred_lft forever2: ens160: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000link/ether 00:50:56:b6:52:89 brd ff:ff:ff:ff:ff:ffinet XXX.XXX.XXX.XXX/24 brd XXX.XXX.XXX.XXX scope global ens160   valid_lft forever preferred_lft foreverinet6 fe80::250:56ff:feb6:5289/64 scope link    valid_lft forever preferred_lft forever3: ens192: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000link/ether 00:50:56:b6:e2:2d brd ff:ff:ff:ff:ff:ffinet6 fe80::250:56ff:feb6:e22d/64 scope link    valid_lft forever preferred_lft forever

But if I do:

root@ubuntubox01:~# ifup ens192Unknown interface ens192

Same thing happens when I try to use the interfaces file. Any ideas as to why ubuntu sees the physical interface but refuses to bring it up saying the interface is unknown?

I am using ubuntu 16.04 Server 64 bits. It is a virtual environment by the way.

I've looking an answer to this problem for days now and I can't seem to find it. I installed Ubuntu 18.04 LTS on my MSI Modern 14 A10M and it won't recognize my iwlwifi wifi adapter. The main problem I have is that some of the solutions I've found I can't try because this laptop has no ethernet ports, so I can't try installing packages that would fix it. I've tried installing Ubuntu 19.10 - where the WiFi adapter works just fine - but the main problem is that it has lot of trouble with temp sensors (overheating) and battery life won't go beyond an hour or two. Can anyone help me get a solution where I don't need to sudo install packages because there's no internet at all on this device

I have a bootable USB, during installation the adaptar wasn't recognized either so I don't know if there's anything that I can do with it to troubleshoot it.

Thanks in advance

I have recently acquired a BeagleBone Black, onto which I've installed Ubuntu using this method. It has all worked so far. I want to use my BeagleBone as a torrent box, but I don't want to do it directly over my Internet connection (I don't think my ISP will like it) - so I've purchased a VPN subscription from a European server. I've manually connected my laptop to this VPN before and the run Transmission. I know that the VPN connection works in Ubuntu, and the host provides setup information for OpenVPN. Annoyingly, the dynamic nature of the assigned IP address means it would change frequently, so when I used my laptop with the VPN I would manually set the listening address in Transmission to the required value.

Ideally I'd like the following setup:

• Transmission runs only over the VPN, and is prohibited from running torrents over the normal WAN connection
• Only traffic directed to Transmission will be accepted or sent through the VPN, all other unsolicited traffic will be dropped
• Transmission uses the appropriate port to listen on, based on the assigned IP address
• OpenVPN starts automatically on boot, which then subsequently starts Transmission
• Transmission's web GUI can be accessed over the LAN, and possibly over the Internet from my WAN connection (i.e. not back through the VPN)

I had set up a vlan in interfaces file. Later on, even after removing the entries and restarting network, the ifconfig command is displaying that interface. Even ifdown isnt taking it down. Ifdown throws error message that the interface isnt configured.

Even after multiple times of examination, I am seeing the same thing again. Wondering why it worked in the same way in the Oracle VM Virtual Box also.Even after commenting-out in the interfaces file, networking restart, networking stop / start, ifdown && ifup, even machine reboot also..!! Same experience..!! Could somebody please try this and explain..?

I would like to connect to my university VPN using openfortivpn client. The client is connecting and the tunnel is up and running.However,my IP (curl ifconfig.me) does not change once connected.I used the same configuration on another machine (same OS, different internet provider) and I could use the VPN without any problem.

My OS is Ubuntu 18.04.4 LTS.

I partitioned my SSD and installed Ubuntu 17.04 alongside Windows 8.1. When I boot into Windows, wifi connects and works perfectly. When I boot into Ubuntu and click the network icon, it shows all the same available connections, but when I make a selection it just tries connecting for 30 seconds before saying "Disconnected - you are now offline".

I'm a noob when it comes to Linux so I'll do my best to follow along. I'm using a TP-LINK TL-WN822N wireless adapter and a RTL8192CU wireless driver. I don't know if I have a problem in my settings, driver, or something else, but I've been looking at 'duplicate Qs' and posts with similar problems for days and haven't gotten anywhere, so I'd really appreciate some help troubleshooting this. Let me know what info I need to add.

I'm having issue when doing a telnet on port 80. I'm getting the following error "telnet: Unable to connect to remote host: Cannot assign requested address".

I'm trying to telnet to google.com on port 80 from any of my Ubuntu servers but when I tried it from Windows it works.

Thanks in advance for you help.

As many of us know, wpa_supplicant has a bug that afflicts the wpa-enterprise (PEAP - MSCHAPv2) to disconnect frequently.

In my experience the wifi went down and retried to reconnect randomly making me very crazy because I couldn't go online !I didn't find out if it depend of the wifi driver (I have a ALFA AWUS 1900 with a rtl8814au chipset) or directly from the wpa_supplicant bug.

Anyway, I tried many distro like debian, fedora and so on... But in the last days I tried Ubuntu 14.04.6 on VirtualBox linked directly the usb wifi adapter, and after installed the driver and set up the network I saw the network worked very well without the frequent disconnections. So today I installed the wpa_supplicant package version from Ubuntu trusty (14.04) on my Ubuntu 18.04 and it seems it works as expected.So I need your help to confirm my suppositions and maybe bring the all community to fix that strange behavior.

I was a beginner and trying to bond my two nic. They are both wireless and support bonding.I was planning to create a bond0 and use it as the primary "nic" to connect to wifi

For my etc/netplan/my_plan.yaml, I have it as below:

network:  version: 2  wifis:    wlx04d9f5c452a9:      dhcp4: yes      dhcp6: yes      addresses: [192.168.1.246/24]      gateway4: 192.168.0.1      nameservers:        addresses: [8.8.8.8,4.4.4.4]      access-points:"wifi":          password: "psswrd"    wlp4s0:      dhcp4: yes      dhcp6: yes      addresses: [192.168.1.110/24]      gateway4: 192.168.0.1      nameservers:        addresses: [8.8.8.8,4.4.4.4]      access-points:"wifi":          password: "psswrd"  bonds:    bond0:      dhcp4: yes      dhcp6: yes      interfaces:        - wlp4s0        - wlx04d9f5c452a9      parameters:        mode: balance-alb

wlp4s0 and the other are both connecting via wifi

for my /etc/network/interfaces

auto loiface lo inet loopbackauto wlp4s0iface wlp4s0 inet dhcpbond-master bond0auto wlx04d9f5c452a9iface wlx04d9f5c452a9 inet dhcpbond-master bond0auto bond0iface bond0 inet dhcpbond-mode balance-albbond-miimon 100bond-slave wlx04d9f5c452a9 wlp4s0

but however, in my cat /proc/net/bonding/bond0, it shows MII status: down

Ethernet Channel Bonding Driver: v3.7.1 (April 27, 2011)Bonding Mode: load balancing (round-robin)MII Status: downMII Polling Interval (ms): 0Up Delay (ms): 0Down Delay (ms): 0Peer Notification Delay (ms): 0

And I use route -n and didn't see bond0 beeing used.

I want to use those two nic to create a bond and use that bond to connect to wifi as default or higher priority (which i guess is done by ifenslave), butI couldn't make the bond works.

I really need your help. Much appreciated!!

With remote working due to coronavirus, I am working at home, and my local kubernetes dns resolution is failing.

when I type:

nslookup localhost

I get:

Server:     127.0.0.53Address:    127.0.0.53#53Non-authoritative answer:localhost.numericable.fr    canonical name = nc-ass-vip.sdv.fr.Name:   nc-ass-vip.sdv.frAddress: 212.95.74.75

and this is messing around with kubernetes dns resolution.

How should I remove the suffix .numericable.fr ( my ISP )

I am running on Ubuntu 19.04

Besides taking a few minutes, I can successfully add a Google account through GOA using a wired network, but accessing it (through Nautilus or Geary for example) returns timeout errors.

Problem appears to be network related cause when I switch to Wifi, it works fine adding and accessing.

I am directly connected to my ISP router, not using any proxy.

What would you advice me to do?Thank you

I recently installed Ubuntu 13.10 on my Lenovo Thinkpad L540. It has problem with the wifi connection. When just booted it works then suddenly it drops the connection and cannot even see the wifi networks.

• I tried to install the windows driver for the wireless card Intel 7260 but I'm not able to extract the .inf file from the .exe that I download from Intel website. With the .inf file I should then be able to install the driver using ndiswrapper but, since I cannot get the .inf file, this way is gone.

• I tried also following other ways. I upgraded the Kernel to the 3.13 from 3.11 but still it doesn't work.

• I tried also to follow instructions such as those from Intel wireless 7260 driver crashes, how do I work around it? but every time I give the command sudo modprobe -r iwlwifi I get:

  FATAL: Module iwlwifi is in use.

6-April-EDIT:

• The command sudo modprobe -rf iwlmvm before sudo modprobe -r iwlwifi, doesn't change the situationi. Still the output to the second command is

  FATAL: Module iwlwifi is in use.

• The output to uname -r is

  3.13.1-031301-generic

• The output to dmesg | grep iwl is a long list made of elements like the following

  [ 2028.111303] iwlwifi 0000:02:00.0: L1 Enabled; Disabling L0S

  plus some few exception lines which give

  [ 2031.232825] iwlwifi 0000:02:00.0: RF_KILL bit toggled to enable radio.

Shortly after system boot, before I start any application, I open the System Monitor and in Network History graph see something like that:

How do I find out which application or process is responsible for this traffic?

I am kind of new in linux environment and I must say that I am loving it even though I am in the learning curve. I have installed Ubuntu 64 bit 18.04 LTS on my Dell Inspiron 7559 using a live ISO over the network.

Everything went like a charm but I see that my Intel 3165 wireless driver is not detected and it says manual-install = true. I did some research and performed below mentioned steps.

1. Downloaded latest Intel 3165 drivers from Intel's website in the form of tar.gz
2. Extracted them and as per the installation guide that came with it I placed the .ucode files in /lib/firmware
3. Rebooted the system

I have also tried the solution posted in of the posts and copied the 7265 ucode files and pasted them as 3165 ucode files in /lib/firmware.

Even after doing above mentioned I am not able to use wifi. Additional driver section in Update manager shows the device grayed out. Wifi works when first booted but after sometime it stops working and system never detects it back again unless I do a fresh installation, hence I am not using wifi now and using ethernet now.

Can anyone please help me with this and guide me on how to install the drivers? Below are the outputs of some commands:

The vlc setting is :

and the $HOME/.config/vlc/vlcrc file is like this.

Also at app port is settled on 8080, pass is 1234 and the IP is settled by ifconfig output result in PC.

So what do you thin i mus to do?

Thanks.

I can connect to my home wifi network. However, internet browsing speed is just very slow.

Interesting fact is, I can connect to the same network from my Windows machine and I don't see any problems with speed. It seems this Ubuntu specific issue.

My Ubuntu laptop has Intel® Dual Band Wireless-AC 3168. I did some research online, found that this issue could be related to linux-firmware. I am using v29.1044073957.0.

But still not sure what the problem is.

I ran wireless-info tool which generated this report.

I have just completed a fresh install of Ubuntu Server on an old PC. The PC is being connected to my local network via Wi-Fi. The Wi-Fi card is a TP-Link TL-WN751ND.

The server connects to the network fine and has Internet access. The issue is that it cannot successfully ping my desktop system and the desktop system cannot ping the server. The server can ping all of the other devices on my network, which, in turn, can ping the server too.

I'm at a loss as to why the Ubuntu PC and my (Windows 10) desktop cannot communicate but everything else can. My network card in the desktop is based on an Intel Dual Band Wireless-AC 7260. The router is a BT HomeHub4 and all systems use DHCP but the router is set to assign each device a static IP. Both systems correctly receive their allocated IPs.

Desktop: 192.168.1.69Server: 192.168.1.70Gateway: 192.168.1.254Subnet: 255.255.255.0

It's probably worth mentioning that the issue persists when using the Ubuntu Desktop 15.04 install I have on the same PC but I'm not sure if this is being caused by a Windows - Linux issue (unlikely, other machines communicate with server fine as mentioned) or something wrong with one of the network cards preventing the two communicating.

Any advice appreciated,Ilmiont
