Hi, I was having problem with wifi in ubuntu 18.04 lts after having recent upgrade, so I followed the steps mentioned here - https://askubuntu.com/questions/1058...with-rtl8723be, but was not able to solve the problem, in another answer I read that upgrading to 18.10 (kernel version 4.18.0-15-generic) will solve the problem but all in vain. Please help to resolve the problem.

[ubuntu] WiFi adapter not found
I bought a HP Pavilion 590-p0057c and installed Ubuntu 18.04.01 on it. When I went to turn on WiFi, settings said: "WiFi adapter not found". Is there a fix for this?

[ubuntu] when i close my laptop lid & open it back up, my wifi will not connect
I have peered through a couple threads & tried out some things but nothing has worked. My laptop is about a month old now, it's a HP - When I first installed Ubuntu 18.04.1 on it my WiFi was completely not found and i had to install rtl8821ce. Once i did that my laptop picked up the WiFi. But its a minor inconvenience. When i close my lid & open it, I have to restart my laptop for my WiFi to work. If anyone has any ideas please help, thanks.

Dns working weird at /etc/resolv.conf
Hi,
I am a newbie in terms of others present here . But I have little knowledge of linux and trying to enhance it more on the go.
The situation that I am facing is when I change the nameserver setting at /etc/resolv.conf to any random ip ( other than local dns server or known public dns servers) it still resolves the request and I am being able to browse the internet without any glitch.
Ideally it should block access to the internet if the nameserver isn't a valid dns server.
I checked this anomaly both with NetworkManager as well as Wicd connection manager on ubuntu 18.04.2 LTS
So instead of nameserver 8.8.8.8 if I put nameserver x.x.x.x ( where x is random numbers ) it still resolves all the requests my client make.
Earlier when I had used ubuntu 16.04 or ubuntu 17.04 , I never noticed this anomaly and my internet would stop if I changed the nameserver to a dns server that is not active.
IF I am missing out some thing , please let me understand .
Thanks

[kubuntu] How to connect to the Internet with a SIM-card?
I have read many posts in here and elsewhere with lots of details that I don't understand.
I have not been able to find any that explains clearly what to do in order to connect.
Almost everyone talks about some modem-manager. When I run it, it says
$ network-manager
network-manager: command not found
When I want to install it, it says
$ sudo apt-get install network-manager
[...]
network-manager is already the newest version (1.10.6-2ubuntu1.1).
Is there no GUI to do that? If not, I can always use the text interface. But I need to know what I have to write. I know there is a working device that connetcs, since it is a dual-boot with W10, and it works in W10.

[ubuntu] DWA-171 Installation Problems
Hi All,
I have recently done a fresh install of Ubuntu 16.04. I have updated all programs and have tried installing my wireless Internet driver multiple times to no avail. I am currently using a D-Link DWA-171 wireless adapter it is using Realtek 8812AU. The installations went fine and managed to install the drivers but when i run usb-devices it shows the adapter is plugged in but there is no driver assigned to it. Is there any way to fix this? I am more than happy to assist with any troubleshooting that needs to happen.
Another thing to note is that when I run lsusb or usb-devices it shows up but when running lshw -C network it does not show the wireless adapter. I have included some code snippets to help out

[ubuntu] Suspension crashes WiFi firmware
Whenever I put my laptop into suspension my WiFi card is killed, as to be expected. However when waking my laptop network manager reports "device not ready." Further probing gives me an error stating my firmware has crashed, as well as "failed to reset chip: -5".
Running the three commands,
makes network manager report "device not managed".
I have already tried
to no avail.
Dell's OEM kernel did not have this issue, and if indeed this cannot be fixed, how can I go about installing Dell's linux kernel?

18.04 -> 18.10. Server can see gateway but can't access internet.
I'm running Ubuntu Server 18.10.
Quick info on the update: During my upgrade from 18.04, it asked about a file and offered to show me a comparison. I looked at the comparison but couldn't resume the update. After rebooting, the update seemed to continue and it had 601 packages to update. So after the packages were updated and I rebooted again, I lost my internet connection.
I can ping certain local IPs. Namely the gateway, but I can't ping something external like 8.8.8.8. I was looking around in my netplan config and things looked fine. So I ran "netplan apply" and was able to ping 8.8.8.8 about 5 times before it stopped working again. This is something I can repeat: "netplan apply" and then "ping 8.8.8.8" yields about 5 successes before the rest fail. (Desination host unreachable) It's strange behavior because you figure it would either work or it wouldn't.
Originally, the server was also my DNS server. I run PiHole on it (built on dnsmasq). But I went ahead and changed the nameserver settings to point to google (8.8.8.8) until I could get things straightened out.
I have a feeling it may be related to the routing configuration. Normally I configure this using WebMin, but I can't access it now.
I don't necessarily need a specific solution to this particular problem, though that would be handy. I would say it would be useful if I could reset my routing configuration to some sort of default or known-good configuration. I used to use my server as my gateway so some of the routing configuration is left over from that.

problems with capturing traffic in monitor mode
I'm running Ubuntu 14.04 LTS (Also, tried with Ubuntu 16.04 and problem repeats). Here is what I want to do:
Put the wireless card on my laptop in monitor mode and capture traffic of other devices in my network. I control the wireless router (access point) to which my and other devices are connected and also these other devices.
I use the following process to capture traffic in monitor mode:
However, I only see traffic originating from my laptop. Also, that traffic is encrypted.
I want to know:
1. How do I capture traffic from other devices as well?
2. How to decrypt the traffic: I want to view everything upto the transport layer (TCP sequence numbers, ACK numbers, etc.)
I believe that since I control all the devices in the network (router and other wireless devices) and other devices also have Ubuntu installed on them, there should be some way.

OpenVPN woring on all but ubuntu systems
I have a mikrotik rb3011 running openvpn server.
This works for mikrotik - mikrotik tunneling, gentoo - mikrotik, mac - mikrotik and windows - mikrotik.
However, ubuntu - mikrotik returns "error=unsupported certificate purpose"
On gentoo I've tested client versions 2.4.2, 2.4.4 and 2.4.6. All works.
On ubuntu I've tested version is 2.4.4.
Both the mac and ubuntu got their config file copied from the gentoo client.
I suspect there is some default config on ubuntu that makes the running config on this client differ from the others, despite identical config files. Does anyone have an idea of what needs to be done differently in ubuntu?

[xubuntu] Bluetooth speaker stuttering on Xubuntu 18.04
Hello!
After much researching around the web for a long time, with no results (trying different stuff), I decided to finally make a topic about it:
I have a laptop Dell Latitude E5430 with a 64-bit Xubuntu 18.04 on it.
I also have this bluetooth speaker, and from time to time, while I'm watching a video or playing audio either from chrome/firefox/opera on YouTube or from a player (like SMPlayer, Parole player), the sound from the bluetooth speaker would stutter. Sometimes this happens not so often. But sometimes it's an occurring thing every few seconds. And it's annoying me.
I want to clarify that when on Windows 7, the speaker had never stuttered. Also, when I use it with my android phone, it had never stuttered. Obviously, it's a software problem with Xubuntu/Ubuntu. I've also had this problem on Lubuntu and Linux Mint (the distros I've used so far, but currently stopped at Xubuntu because of the lightness and stability).
Anyone can help?

[ubuntu] 18.04.2 Slow wifi conection - Realtek r8188eu
Hello everyone :)
I really hope you can help me with this.
I'm fairly new to ubuntu, and when I first installed it I didn't notice any problems but within a couple days the internet connection started going on and off. I use a Realtek r8188eu usb adapter. Aparently ubuntu isn't very fond of it but I only figured it after all of the following:
I basically couldn't use the internet at all. One day I just turn on the computer and it works. Just like that... BUT the internet was way too slow. Running speed tests online gave results like 1-4 MB/s downloading and 2-10MB/s uploading. Since I was a bit in a hurry to upload some files for a school work I basically just tried most of the solutions I found on this forum and when I got around 8MB/s download and around 20MB/s upload I uploaded what I needed in 2min (instead of 174 hours as it informed me before). But then I got greedy and tried a few more and now it went back to initial speeds.
Current status: No idea what definitions I have meddled with and I still haven't come to any solutions...
I run : wget -N -t 5 -T 10 https://github.com/UbuntuForums/wire.../wireless-info && chmod +x wireless-info && ./wireless-info
