Installing WiFi Adapter Driver in Linux Mint 19
A1 : No, you needn't install the driver. It is already included in Ubuntu It is r From the module aliases:. For example, ifconfig says that my ethernet interface is enp0s Therefore, looking for clues, I'd check:.
Post your findings in an edit to your question and I will edit this answer to add troubleshooting steps. After studying the info according to the recommendations I decided to check the Ethernet connection between the hub and the Adapter. The problem was in the cable.
Now the hub is responding. Thanks for usefull help.

I guess when this device is plugged in, udev sets it up, but how does it know that this USB device is actually used as an interface that connects to Ethernet and hence routes traffic over it? You already have installed the driver. It is most likely just an adapter that uses the USB-net driver.
The system knows the device from the IDs in lsusb. The Linux kernel offered by most distros as default already contains a large number of drivers. All kernel modules can contain patterns that describe for which devices they can be used.
These patterns are called alias. The rest of the aliases matches on values in the USB descriptor. The driver itself will take care of telling the kernel that it represents a device that has a representation in other kernel layers, e.
These upper layers then will take care of other steps, sometimes using interactions with user space, to initialize the network interface, set routes etc. Sign up to join this community.

What I want to know is, how is this working without installing any specific drivers?
Where is the code that detects and manages this? Thanks in advance. Engineer Engineer 4 4 silver badges 15 15 bronze badges.

Network Utilities. Posted on March 16, by Michael Opdenacker. Since Linux supported devices are often difficult to find, I'm glad to share my investigations here. When you use an embedded development board, you must connect it to your computer with an Ethernet cable, for example to transfer a new kernel image to U-boot through tftp, or to make your board boot on a directory on your workstation, exported with NFS. You could connect both the board and computer to your local network, which would still allow your computer to connect to the Internet while you work with the board.
In a training environment, you are also likely to run out of Ethernet outlets in the training room if you have to connect 8 such boards. Hence, a direct connection between the board and your workstation's Ethernet port is often the most convenient solution. If you can't use WIFI to keep your computer connected to the outside world, a good solution is to add an extra Ethernet port to your computer by using an USB-to-Ethernet device.
My colleague Thomas and I started looking for such devices that would be supported by Linux. Here are a few that we found:. So, I recommend the Apple device.
I event posted a comment on the Apple Store, titled "Perfect for Linux"! I hope the Apple droids won't censor it. If the reference changes, it could mean that they switched to another chipset, without changing the model name. This happens often with other vendors, unfortunately. I can't tell whether this could happen with Apple. This was the first Apple device I ever bought…. We're an Apple shop, so we have plenty and that'll do for the short term while we track down a better PCI-X ethernet adapter for this server.
After plugging in the Apple USB Ethernet adapter, it does show in the results of lsusbbut does not show in the options when I run system-config-network-tui. What other steps might I be missing? Of note: I do now see a "dev" network interface when I run ifconfig -a that wasn't there before I installed the drivers. Is that the USB ethernet adapter? If so, do I alias that or use that as the interface's device in system-config-network-tui?
Not to mention I couldn't get an IP to stick to it when configuring using system-config-network-tui. I can also ping hosts on that subnet, so this is working.
The main issue appears to have been the conflict between the hard-coded alias and the asix module trying to register as the same name.It can easily carry network traffic, multiplexing it along with all the other bus traffic.
There are several USB class standards for such adapters, and many proprietary approaches too. This driver originally 2. In current Linux it's now a generalized core, supporting several kinds of network devices running under Linux with "minidrivers", which are separate modules that can be as small as a pair of static data tables.
One type is a host-to-host network cable. Those are good to understand, since some other devices described here need to be administered like those cables; Linux bridging is a useful tool to make those two-node networks more manageable, and Windows XP includes this functionality too. They act as Hosts in the networking sense while they are "devices" in the USB sense, so they behave like the other end of a host-to-host cable. Unless you listen to Microsoft, who will tell you not to use such vendor-neutral protocols.
It makes sense to have a common driver core because only a handful of control and setup operations really need product- or class-specific code. And for some reason, vendors seem to dislike using standard framing in their Windows drivers, so many minidrivers need to wrap a technically-unnecessary layer of headers around Ethernet packets for better interoperability. Another approach to using IP over USB is to make the device look like a serial line or telecommunications modem, and then run PPP over those protocols.
Here's an incomplete list of devices that the usbnet driver works with. It's incomplete because Linux doesn't need to know anything specific about products correctly implementing the CDC Ethernet class specification. It's also incomplete because products that use specialized chips or which reuse other product designs may be repackaged without changing how they work.
Two devices with different brand labeling on the box and device may look identical at the USB level. Note that before Linux 2. With older kernels, just "modprobe usbnet" to get everything; newer kernels modprobe the minidriver, which depends on usbnet to do all the USB-specific work. That ALI code seems to need a seven byte header that nobody's taught Linux to use.
Likely better status handshaking would help a lot. Seek out other options if you can. I've had the best luck with the designs used by Belkin and NetChip. There are other USB 2. A single USB 2.
There's another interesting case that the usbnet driver handles. If that device talks like one of the host-to-host adapters listed above, a host won't know it's talking to a PDA that runs Linux directly. One such boot loader is BLOB. Do NOT add the "usb d net" driver, just get the latest "usbnet" patch if you have one of the newest Zaurus models. Since that's the only USB networking protocol built into MS-Windows, it's interesting even though it's a proprietary protocol with only incomplete public documentation.
The driver is young, but it seems to work with at least some Nokia cell phones. The cable devices perform a master-to-slave conversion and a slave-to-master conversion The PDA side initialization is a bit different, but the host side initialization and most of the other information provided here stays the same.
It only needs to wrap network packets in one of a few ways, without many demands for control handshaking. In addition to the "software emulated" adapter model used in smart peripherals, there are also single-purpose adapters using real hardware. This originally used separate driver, but then it merged with "usbnet".

The Overflow Bugs vs. How to put machine learning models into production.Updated - January 5, by Arnab Satapathi. Ethernet ports are almost gone from laptops, unless it's a heavy gaming laptop. Thankfully this problem could be solved easily with a USB to Ethernet adapter. Almost every PC hardware manufacturers are constantly trying to make their laptops and ultrabooks thinner and even more thinner.
Leaving users to deal with many adapters, docs and dongles. So, here's a list of 14 different USB Ethernet adapter to give you an overview and insight. It will definitely help pick the best product for your purpose. But Windows 7 may require manual driver installation, specially when not updated. As default inbuilt USB to Ethernet driver has a wide range of hardware support.
There should be no need of driver installation on macOS Though there's few report regarding manual driver installation to get the adapter working properly. A Gigabit adapter on USB 2.
May be there's a type C port on your phone, so you can use the adapter both on your laptop and smartphone. And of course the adapters listed here supports all the basic Ethernet functionalities.
It's a descent usb ethernet adapter with 3 extra USB 3. The casing is entirely made of plastic, though doesn't feel cheap. You many feel the glossy plastic body somewhat disappointing. It's prone to scratches, if rubbed against hard surface. But I've to say the adapter performs reasonably well, both as a ethernet adaptor and USB hub. If you're thinking about to connect a wireless keyboard, bluetooth adapter or 2. The reason discussed at the end. It's a aluminium body adapter, so considerably rugged compared to the previous one, and there's no USB hub.
As said before, this adapter is quite well built with sufficiently strong cable strain relief. So you can expect a relatively longer life when handled roughly. There's 3 indicator LED on the adapter to show various status like power and data transfer speed. However you may feel it annoying, specially when using in a darker environment.
Though the all plastic body is not that great. On linux 4. Another cheap yet quality usb to ethernet adapter from TP-Link. Build quality is reasonably good, though it's all plastic construction. The most notable feature of this adapter is the foldable adapter cable and compact size.
I'm using one from Oct, still no fraying sign on the cable. It costs less than half of the Plugable adapter, at least for me. When it's about expansion port selection, Mac system are always a bit different. Previously there was Ethernet ports on Macbooks, but on newer models they're totally extinct.
Macbooks from few years back had USB 3. So you can use any of the above type A adapter without any problem. But latest Macbooks from has only and only Thunderbolt 3 ports, there's 4 of them on the 15" model. Thankfully thunderbolt 3 uses the USB type C port, and they are pin compatible. So any macOS compatible usb C ethernet adapter should be usable too.
