One of the most serious problems that I often faceThere are Linux users, this is Wi-Fi. This is because WiFi drivers can often be missing from the kernel. As a result, subscribers face various “Wi-Fi not working” problems. These are problems that are much more common when using third-party Wi-Fi modules.

Preliminary Checks To Diagnose Internet Problems

Why did my wireless Internet suddenly stop working?

If your wireless connection suddenly crashes, restart someone else’s router before trying anything else. Disconnect the entire router or turn it off. Wait 2-5 minutes before reconnecting this item. Wait another 5 minutes and try to connect again.

There are a few things to check before proceeding with your connectivity troubleshooting. This:

Does the network have Internet access? They check the internet connection on your mobile phone to get the correct answer quickly.
Are you using one of the best compatible Linux network adapters available today? If one NIC is incompatible with your version of Linux distribution, it will not work.
If you are connected to the Internet with a stimulation connection, are your cables connected correctly? Make sure o The cable ends are not loose.
Some laptops have an internet connection that you can use to turn Wi-Fi on or off. Make sure it’s on.
Open the system settings and check if the WLAN switch is working.

Solution 1: Hardware And Software Issues

Why did my wireless Internet suddenly stop working?

Next, you need to determine if your internet problem is related to a hardware Wi-Fi issue or a software connection. The problem with wifi can be both. However, hardware connection problems are relatively easy to resolve. All everyone needs to do is open each of our command terminals in Linux and type the command after:

This is a very easy way to find out if your hardware is working or if there is a problem. Local host address estimation schemes for a network interface controller (NIC). You may need to salvage your system or repair it so you can rivet it yourself if something goes wrong.

If the ping is successful, there is no hardware problem, but the person cannot see your Wi-Fi card. Read on to find out what you can do – fix it.

Solution 2: Reinstall Reinstall The ISO Drivers

Doesn’t the original Linux distribution recognize your Internet drivers? Try reinstalling the drivers to make the ISO easier. If you had a full clean install, you’ll need this ISO somewhere. Common connection errors can sometimes be easily fixed by reinstalling each of our drivers from the original ISO file.

Special step: To do this, go online to the page for the corresponding version of your Sprint system. If you are using Ubuntu, you should be able to download the latest Ubuntu 20.04.2.0 LTS translation from here, from another device, or integrate an Ethernet connection in Linux. Copy against each other to your home directory.

Step 2. Open the appropriate Linux command terminal and enter watch commands to manually mount the image as a CD.

Step 4. Activate the “CDrom on Ubuntu” option on any tab of the UBuntu software and enter “Close”.

Why WiFi is not working in Ubuntu?

Step 5. Finally, go to the Additional Drivers tab, Software & Updates, select the driver and click Apply Changes.

Sometimes Ubuntu may not just display additional drivers. In this case, we have to download the proprietary drivers from the Internet. Sometimes the wifi still doesn’t work despite the extra staff. If you are having this problem, use the method below.

Solution 3: Fix “No Wi-Fi In Ubuntu” Problem With Broadcom Wireless Adapters

Step 1. This method only applies to Broadcom wireless adapters (Broadcom 43 series). Make sure you are not using another wireless adapter by entering this command in a terminal:

You will see the wireless adapter that comes with the BCM43. Otherwise, do not continue using this method.

Step 2. Next, remove any Broadcom card drivers that may already be installed on your personal system using the following command:

Step three or more: Connect to the Internet with an Ethernet cable and use this command to automatically organize your Broadcom drivers

If you don’t have Ethernet, you will have to manually install the most important drivers on another Linux system, remembering to copy the drivers there and paste them into the problem system.

To do the following, first check which version of Ubuntu you are using by entering the following command in a terminal:

Then download the wireless driver from this link to select the appropriate Ubuntu. This will be the DEB file. Transfer it to your system via USB without a Wi-Fi driver.

You can now deploy the package by double-clicking on it, optionally using the following commands:

Solution After 4: Can Your Distro Detect The Wireless Device?

Sometimes your Linux distribution (Ubuntu or otherwise) cannot detect your wireless device if it detects:

Step 1. Go to your Linux administrative terminal and enter the following by running the command:

If you are using an internal WLAN card, use instead the following command:

You can also rely on lshw to find out if your computer system has a wireless device. However, to do this, you first need to install the lshw tool on the right computer. Here is your current order:

You can see something (or similar) below

If the operating system can find credit cards and you get a positive response when your network card has been identified, you’re in luck. Ubuntu usually defines it as “Ethernet or Network Controller”.

Make sure the drivers for your WLAN adapter are actually available; Install one and test it: see Device Drivers. Check your internet connection: see Wireless connections.

This command displays a list of modules. Enter the following command to activate your. Replace “module name” with the name of your computer’s network instance, chipset

If your chipset is RT2870, your command should be:

Pro tip: Google the name of your Linux chipset, i.e. H. “RT2870 Linux” to see if this Linux distribution supports your hardware or not.

Run the lsmod command again in the affected terminal to verify that the module was loaded successfully.

Solution 5: Automatically Charge The WLAN Module At Startup
