How to Connect the Adapter to a Computer

The other day, I suddenly discovered that we have no detailed universal instructions on how to connect a wifi USB adapter to a computer. I hasten to fix this misunderstanding in this post on setting up a Wi-Fi adapter!

Method for connecting a computer r WiFi via USB adapter

Buying a “large” desktop PC, few users think in advance that in the future there will be a need to use Wi-Fi on it. However, if such a moment has arrived, then the only right solution would be to install an additional PCI or USB adapter. With it, you can connect a regular desktop computer to the Internet via a wireless network. By the way, we devoted a separate large instruction to choosing an adapter. It will be useful to read before buying. Also, a separate instruction is devoted to setting up wifi on a desktop computer. Read it, too, will not be amiss.

How to connect a USB WiFi adapter to a computer?

Let’s deal with connecting a WiFi adapter to a computer. I recommend using the version with the USB connector, as it is more universal. If the PCI adapter can only be inserted into the desktop motherboard, then USB can also be used with a laptop.

The procedure is as follows:

  1. Plug adapter into USB port
  2. Start using WiFi internet

Yes, everything is so simple, but you thought? If you have Windows 7, 8, 10 installed on your computer or laptop, then nothing else is required.

No, it will work on 2.0, but for your convenience, maximum speed can be achieved only on the latest standard.

And why then in the box with the adapter was the installation CD? As for the disk with drivers and software, which is most often included, it makes sense to get it only if you have outdated Windows XP. Most often, it is for her that you need to separately install the driver.

The installation program, in fact, replaces the standard wired in Windows, so installing it or not, is also a business matter. You can install out of curiosity. Sometimes, by the way, it happens that through it you can put the USB adapter into WiFi access point mode and distribute Internet from other computers to other gadgets.

How to configure a WiFi adapter on a computer via a USB port?

Well, let’s get to practice. We connect the WiFi adapter to the computer in the USB port

How to Connect the Adapter to a Computer

And wait until the new USB device is recognized and successfully installed

If this miracle did not happen, then in the old-fashioned way we take a CD

And install from the driver disk.

After that, the WiFi icon will appear in the list in the lower right corner of the panel. Clicking on it will open a list of available wireless networks for the connection

We select the one we need. That is, from your router, to which you have access. And click on the “Connect” button

And enjoy the internet through wifi.

If there is a WPS button on the adapter case, then you are extremely lucky, since you can connect to a router and configure it to work with its wifi network in automatic mode.

To do this, activate the WPS mode on your router

And briefly press on its body a similar WPS button.

Then we also press this button on the adapter once. After a few moments, the computer or laptop will be online.

This is how easy it is to connect a wifi adapter to a computer and configure via USB. I’m sure you will succeed too! If you have any questions, ask in the comments.

Connect and set up a WiFi router to the Internet, most likely everyone can. The next step is to make sure that our personal computer without a Wi-Fi router starts to catch the Wi-fi network. For this we will need to purchase wifi adapter and install it on the computer. Applying such usb adapter your computer can truly receive Wi-fi over the air without being tied to wires, so you can transfer your PC to any convenient place at any time. Over, we installed a router for those purposes in order to get rid of wires in the house. Do not know how to choose an adapter, read the topic about “Best USB Wi-Fi Adapters“.

After we installed the router, made the Wi-Fi network settings in the house, if it means office at work, accordingly all our mobile gadgets such as a laptop, mobile phone, tablet will instantly find and connect to a Wi-Fi network, without wires “by air”. If for some reason you still do not know how to configure a wi-fi router, I recommend reading this topic Configure a Wi-Fi router. TP-Link TL-WR841N Router. Because in these devices, the manufacturer took care of the built-in Wi-Fi receiver, and we are talking about a computer that is not initially equipped with this Wi-Fi adapter and most likely would also like to connect to the global network without red tape with wires. For these purposes, there are a couple of options:

The first method is most likely not suitable for us, since it involves connecting our computer to the Internet by laying a network cable to it. And since our topic about Wi-Fi adapters, this option doesn’t suit us.

And here is the second method, which we will consider just for us. This option is suitable for us in this case. Now we will consider two types of adapters, internal and external, in simple terms, a Wi-Fi adapter that looks like an additional board is inserted into a special PCI slot which is located in the middle of the computer and is called internal. It will take a little knowledge to install it. And it looks like in the pictures below.

The most convenient and easy to configure and use is an external Wi-Fi adapter that we will connect to a desktop computer today. After you read this topic, the computer will finally become independent of network cables and become portable and will be able to catch a Wi-Fi network through the air. It was one of these usb Wi-fi receivers that I put on my PC, the appearance of which you will find in the pictures below, such Wi-Fi adapters are also called flash drives.

Now that we’ve got a little familiarized with what kind of wi-fi devices are there, it’s time to start connecting it to the computer.

Let’s start installing the wifi adapter on a TP-LINK computer

Let’s get a Wi-Fi adapter and connect it to the computer. Despite its small size, I recommend connecting to the USB connectors that are located on the back of your computer. Suppose all your sockets are busy, then you can use various extension cords or the one in the kit to connect the TL-WN725N adapter.

After you insert the device into the usb socket, your operating system will automatically start looking for drivers, as a rule, it finds them by itself, it is possible that Windows will not find them and will give an error. Do not worry, ignore it, then insert the disk that comes with it and install the drivers and utilities from the disk. If for some reason the installation disk is missing, I recommend searching in the search engines for the Wi-Fi adapter model in my case it is TL-WN725N. Well, if you have not already found it, I recommend reading this topic. How to find the driver of any uninstalled device.

I don’t see the point in describing the process of installing drivers. Now we can only wait for the end of the installation. After the installation is completed, in the notification panel where the watch is located, you can observe the status of the Internet connection in the form of sticks with a yellow snowflake, this will indicate that our Wi-Fi adapter found networks available for connecting.

Now click this status to connect Wi-Fi if there is an available network to connect, select it and click on the “Connect” button.

After clicking, the window pops up, here we need to enter the password for the Wi-Fi network and click OK as shown in the photo.

Congratulations if you see white sticks in network status. This will indicate that your computer is connected to a Wi-Fi network. Congratulations!

As I say, this procedure takes very little time to connect and configure our TP-LINK TL-WN725N WiFi network adapter, and most importantly, thanks to this device, we connected to the Wi-Fi network by air independently.

Using such adapters, be it TP-LINK or any other, to install them and put them into operation is not particularly difficult for them, many thanks to them. Such adapters on the market are usually not expensive and there are a lot of benefits from them.

Now a few words about what kind of adapter should I buy to connect a personal computer to a Wi-Fi network? I think that there is absolutely no difference whatsoever, just the external USB adapters are more versatile and easy to install and configure. Over, you can take it and install it on another PC at any time.

Now you understand how convenient and practical it is to use a usb Wifi adapter to connect your home computer to the World Wide Web, and most importantly, very quickly and easily without pulling along heaps of network wires around the house. Good luck to everyone to remember to share the topic and ask questions in the comments.

Sometimes you can find a failed home laptop or tablet, some of the details of which have already been used as spare parts. Usually, a wireless device remains in them and the question arises: is it possible and how to connect a “laptop” WiFi module to a PC. To make it real when using adapters, both purchased and home-made.

Can I use a “laptop” Wi-Fi module in a PC

The laptop is a portable device and, accordingly, is equipped with modules that save space inside the case. Naturally, the topology of the printed circuit board and the shape of the connectors for connection, which is called “MiniPCIe” for portable devices, are changing, while the pin assignment remains the same as for PCIe.

The schematic device does not change either; the wireless controllers for both portable equipment and desktop personal computers are almost identical.

Note! In order to carry out operations with electronic components, at least basic knowledge of electrical engineering and circuitry, as well as practical skills in working with soldering and auxiliary equipment are required. It should be remembered that working with radio modules on an intuitive level can lead to their failure.

How to connect a Wi-Fi module from a laptop to a computer

The compatibility of the portable module with the PC motherboard is ensured by means of a physical adapter, which is an ordinary adapter that reassigns the pins necessary for the device to work. The only electronic “body kit” designed to provide power and located on the front side of the circuit board is a pair of electrolytic capacitors and a voltage regulator (3.3 V). Almost always, two antennas are included. The sequence of actions when connecting a WiFi notebook miniPCIe card to the PC PCIe slot is as follows:

  • Disconnect the WiFi module from the laptop motherboard;
  • Insert the module into the miniPCIe connector of the adapter, securing it with bolts of the appropriate size;
  • Using the connectors on the ends of the coaxial cables to connect the antennas and the WiFi module;
  • Insert the WiFi adapter from the laptop to the PC into the PCIe connector of the motherboard;
  • Configure the device in the operating system by installing the appropriate driver controller;
  • Set up a connection by entering the name of your home or office Wi-Fi network (SSID) and password, then connect.

Good to know! If the brand of the WiFi adapter is unknown, the driver for it can always be found using the PCI / VEN identifier. In Windows, to do this, right-click on “My Computer”, select “Properties” and “Device Manager”, find an unknown Wireless device, open its properties and select “Device ID” from the drop-down menu. Then enter the copied identifier into any search engine, a series of queries will be issued on it, from which to choose the appropriate one. On Linux, the response from the hardware installed in the PCI and containing information about the device model is obtained using the lspci utility from the pciutils package. To determine the WiFi module, enter the command “lspci | grep wireless. ” Knowing the model, the necessary drivers can be easily found on the manufacturer’s website or third-party software developers.

Choosing an adapter from a laptop to PC. PCIe-miniPCIe Adapter

In choosing an adapter that allows you to connect a wireless module from a laptop to a PC, there is nothing complicated, because, as mentioned above, these are devices of the same type. Particular attention should be paid to the presence of antennas in the kit, the quality of the connections, tinning and coating of the printed circuit board, since such an adapter has a minimum of electronic components, it can be manufactured independently. To do this, you must:

  1. Prepare a soldering iron, tin, rosin, napkin with a set of drills, one-sided textolite, details in accordance with the scheme;
  2. Download and print a printed circuit board print on glossy paper; for this it is necessary to download the SprinterLayout program (archive with the circuit board);
  3. Strip the copper surface of the PCB blank with sandpaper (strictly according to the size of the printed circuit board), degrease with alcohol or acetone;
  4. Attach the print with the printed side to the copper surface and press down with a hot iron;
  5. Cool the resulting blank of the printed circuit board, soak in water for 20 minutes and remove the remaining paper from the print, you will get a print of the tracks;
  6. Etch the board in ferric chloride in accordance with the instructions on the package;
  7. Drill all holes;
  8. Tin all tracks with tin, install and solder electronic components.

Note! It is highly recommended that you use a multimeter while manufacturing electronic devices. This is a device that allows at an elementary level to carry out pre-start checks of resistances, capacitors, inductances, search for short circuits, board power, semiconductor element characteristics (diodes and transistors).

Homemade Wi-Fi adapter in the housing from a flash drive. Laptop Wi-Fi pinout

Connecting the WiFi module from the laptop to the USB (read as “USB”, Universal serial bus. Universal serial data bus) to the port is quite problematic. To make a simple WiFi adapter in a flash drive case you will need:

  • Wireless module from an old tablet with a 2.4 GHz remote antenna;
  • The case from a flash drive with a USB connector of type “mother”;
  • LED (optional);
  • Soldering iron, solder, rosin or flux.

Next, it is necessary to solder the Wi-Fi module contacts by soldering to the serial port connector according to the pinout. After that, also solder the antenna to the ANT and GND outputs, it is highly recommended to install an AL 307 LED on the 3.3 V pin of the cathode and on the USB 5 V pin of the anode (in Otherwise, it is necessary to solder by hanging mounting the DCDC converter). Finally, collect everything and place it in the case from under the flash drive, if necessary, fix the details with hot glue.

To connect using such an adapter, you must connect it to the USB port and install the necessary drivers. Since the device may not be recognized by the system, it is recommended to download drivers for it in advance on a miniature USB flash drive, which can be placed next to it on the key fob. You can also make a double-sided device from such a Flash-memory, a WiFi-module and a suitable case: on the one hand there will be a drive connector with drivers, and on the other. A WiFi adapter.

Attention! Soldering of electronic elements should be carried out in a well-ventilated area. When working with contact pads of modern printed circuit boards, the most suitable option is to use a soldering iron tip for SMD components. If the radio component needs to be soldered, it is best to use the desolder, which is part of many amateur soldering stations.

Additional Information. When deciding how to connect a WiFi-module from a laptop to a computer, a pinout should be at hand. A diagram indicating the purpose of the contact pads, for miniPCIe it looks like this:
