Hi,

I just finished a fresh installation of Ubuntu 20.04 and have been trying to get my USB Wi-FI Adapter (TP-Link AC1300 T4U v3) to work.

After following a number of guides, I believe I have managed to install the device, but am unable to enable it and use it.

I am currently using my android device as a usb tether to access the internet so I could setup the adapter.

Thank you in advance for the help.

[ubuntu] USB wifi connection is suddenly off

≪ Previous: [SOLVED] TP-Link Archer AC1300 T4U Setup

Ubuntu 16.04 LTS running in a desktop PC.

I'm using a TP-LINK TL-WN722N.

It works ok until for unknown reasons there is no more wifi signal. Needless to say alll the other devices, cell phones and a couple of notebooks (running Windows) have wifi.

Sometimes unplugging un plugging back the USB stick works, sometimes I have to restart Ubuntu. And sometimes it will not get any wifi signal after restarting.

It is working at this moment but who knows in the next minutes.

Is there something I can do to fix this issue?

Thanks.

≪ Previous: [ubuntu] USB wifi connection is suddenly off

I'm running Ubuntu on an Orange Pi Zero and I have it configured pretty well, except the wireless. I can manually bring up my wlan0 interface successfully when SSH'd over the ethernet link, but I can't get it to connect at startup. wpa_supplicant was giving me issues, but I am able to successfully configure /etc/network/interfaces file to use a wpa key and access point, along with a static IP address using the following configuration:

Code:

auto wlan0

iface wlan0 inet static

  address 10.10.10.140

  netmask 255.255.255.0

  gateway 10.10.10.1

  broadcast 10.10.10.255

  dns-nameservers 10.10.10.125, 10.10.10.126, 8.8.8.8

  wpa-ssid "my cool access point that works!"

  wpa-psk "my cool password that works!"

The strange thing that is happening is that on startup, it seems to connect to the access point and get connectivity to the network, but then disconnect almost immediately. It's then non-responsive until I plug the ethernet cable in and wait for it to get a dhcp address. I run a constant, quick timeout ping of the interface while the system is rebooting on my Windows desktop "ping ubuntu-server-ip -w 100 -t" and I watch the system come online for two pings, then it goes offline again.

Code:

>ping 10.10.10.140 -w 100 -t

...

Request timed out.

Reply from 10.10.10.140: bytes=32 time=3ms TTL=64

Request timed out.

...

The Orange Pi Zero has no display interface, all activity is performed over the network once the system is booted. I can't see what is going on, and I can't find anything in the normal system logs explaining why it would bring the interface up and then shortly after that take it offline. I'm _guessing_ that some conflicting service is taking over and not connecting to the access point properly (because it's not configured in whatever service is doing that), but I can't figure out what may cause that.

Does anyone know how to troubleshoot what may be causing the network interface to come online, and then quickly go back offline? Maybe point me at a log file or something?

Thanks!

PS this device is going to be on a remote part of my property that I don't have hardwired network access, otherwise I'd just plug in to old reliable ethernet. :)

≪ Previous: [lubuntu] wireless security confusion

Fresh install of 20.04 on a newly built machine with old parts. G1840, H81 motherboard, 4 port pcie ethernet card + 1* built in port.
I've got a nas, PX4-300D and I'm planning on using this new machine as a pi-hole, owncloud and plex server.
I'm looking to use all the ethernet ports as a bit of a switch. The NAS has bonded ethernet ports for a total of 2gbit.

Is it possible to set up all 5 ports as a bridge so that 1 port feeds into the machine from the local network and 2 of them feed in from the NAS? My VDSL modem router handles all the DHCP networking.

So it'll look like:
Router --> Powerline network --> machine <--> NAS

I kind of got it working manualy via the CLI and brctl utils and restarted the machine and it all broke.

I'm a novice with Ubuntu but understand it's an incredibly useful tool but there's so much to learn.

June 29, 2020, 7:18 am

≫ Next: Reset my network settings

≪ Previous: How do i make hostname.local into just hostname for resolving local dns

OS: Ubuntu server 20.04

I have two USB Wifi network cards, one internal interface. Long story short: sometimes the internal card is called wlan0, other times wlan1, ... when I add or remove cards, the naming becomes completely unpredictable.

I have read documentations saying that there is something like a 'predictable naming' convention. What confuses me is that whenever I read the documentation (see: https://www.freedesktop.org/wiki/Sof...nterfaceNames/), it says it should be disabled and therefore in place by default, but it doesn't seem to be. If I look in '/etc/systemd/network/', I don't see any rules defined either. Needless to say I'm confused.

What I would like to become is that all NIC's always have the same name, regardless if one is unplugged or not. The names can be based on MAC or usb-portnumber. Either way, if I plug in a card, I'd like it to have the same name each time, preferably on MAC address.

P.S. I realize with NetworkManager I can assign profiles/connection based on mac address, however I want to use networkd for managing my connections;
P.S2. When it comes to netplan: the documentation says that can filter based on MAC address or driver, but for networkd, it says I can only match on names... which kinda defies the whole purpose.

I'd really appreciate if someone could shed some light on this.

everytime i restart my box i have to enter:

The problem of the wifi signal dropping and coming back up persisted.

Another thread (https://askubuntu.com/questions/1200...-and-bluetooth) also mentioned installing a custom firmware (https://github.com/thebitstick/surfacego-wifi).

I fear bricking my laptop if I try something for a different device altogether. And so I haven't installed any custom kernel modules or firmware. Is this really the answer? If so, which one?

When I start Ubu, my Internet connection ALWAYS starts disconnected. Clicking "Connect" tries for about 20 seconds then gives up.

I have no idea what's wrong. The WiFi connection worked perfectly when I installed Ubu from a thumb drive, including downloading "third-party" drivers and software, but now that installation is complete, it is extremely difficult to establish/maintain a connection (which I'll always lose a few minutes later.)

I'm typing this from Windows on the same PC using the same Wifi adapter. Any ideas? :mad:

Question 1: Before the SSH "handshake" between the Client and the Server... where in the process does SSH Protocol do it's thing...

This is based on the assumption that...

Question 4: SSH traffic travels over the internet as "Frames" ... with a header and trailer... via the following steps... Right?

1 - It all starts out with the raw data at the Application Layer that Computer-1 wants to send to Computer-2... Maybe something as an ASCII text like... "Hello World"

2 - ??

3 - At the Transport Layer the the data got segmented with a Header added and thus became TCP Packets with Source & Destination Ports included

4 - At the Network Layer those TCP Packets had an additional Header added and thus became IP Packets with Source & Destination IP addresses included

5 - At the TCP/IP Updated Model's Data Link layer the IP packets had another Header added plus a "Trailer" with the Source & Destination Mac Address induced

I've Googled & watched Videos until my eyes have rolled back in my head... so I'm hopeful that some kind soul will walk through this with me.

≪ Previous: [kde] nextcloud webdav

(Note: This is a follow up to my SSH thread but this is about Tunneling and SSH and so I thought it merited it's own Thread.)

From the Windows Command line...
WinPCpro-L-1 at Location 1 connects over the internet to a Ubuntu Server at Location 2
with...
Putty.exe username@xxx.xx.xx.xxx -P aaaaa -i .\username.ppk
And after entering the password...
WinPCpro-L-1 is connected to the Ubuntu Server and can remotely enter commands.

(I've actually got this working but I want to know what is going on under the hood.)

Question 1:
After the connection is established the commends entered on the PC's keyboard will ultimately be sent to... the Ubuntu Server at xxx.xx.xx.xxx:aaaaa -- that is Public IP Address xxx.xx.xx.xxx Port aaaaa
So this means the Linux Server is "listening" for SSH traffic on Port aaaaa
Right?

Question 2:
Does the Windows Command Line entry
Putty.exe username@xxx.xx.xx.xxx -P aaaaa -i .\username.ppk
also setup a "tunnel" ?

Question 3:
The term "Tunnel" confuses me as it makes me think of some kind of magic hardwired permanent connection... which of course is impossible over a packet switching network like the internet...
So the "tunnel" is virtual... as seen between the TCP/IP Model's "Application" Layers...
Right so for?

Question 4:
And before "Tunneling" can begin the two computers must communicate with each other and setup/agree to things... like maybe what "Tunneling" protocol is going to be used, etc...
Right so for?

Question 5:
So now the SSH "connection" has been established between the 2 computers
And the "Tunneling" protocol has been agreed to by the 2 computers...
Or does this happen differently?

Question 6:
So after the two computers agree to talk and "how" they are going to talk...
- the raw data from the PC Application gets processed by the "tunneling" software...
- and then sent to the SSH client for further processing and forwarding down to...
- the TCP/IP Model and then to the
- Transport/TCP Layer and then to the
- Internet/IP Layer and then to the Data Link Layer and then
- out the NIC door to the network...
Or does this happen differently?

Sorry for all the confusion but I've dived in to learning this stuff now and really appreciate anyone helping me find my way.

Thanks for any help.

PS-1 Hopefully I'm in the right font size so I don't get in trouble again :-)
