Limited Wi-Fi access on a laptop with Windows 7

Many users when working per PC or laptop face the problem of limited access to Wi-Fi network. In this article, we will deal with how to eliminate such a problem in Windows 7.

Limited Wi-Fi access

The reasons causing this problem with Wi-Fi, several, and not all of them are directly related to malfunctions in the operation of the network or devices. For example, the "stitch" can anti-virus program, bump access to the network. Next, we consider the most common options for solving the problem.

Cause 1: Router

The first thing to pay attention to is a router, or rather, its incorrect work or settings. Check, it is possible to check if the router can be "tupit", trying to connect through it to the Internet from another device, for example, from a smartphone. If there is no access, you should run it (router) to reboot, disconnecting, and then turning on the power.

If the work of Wi-Fi is not recovered, the next step is to check the router settings. Under this article, we will not describe this process in detail, since on our site there is already a sufficient number of instructions for different models. You can find them by entering a request to "configure the router" in the search field on the main page and pressing ENTER.

Not excess will also check the relevance of the firmware. Its obsolescence can lead to many issues, including the discussed in this article. The update does not take much time and will eliminate this factor.

Cause 2: Problems with USB

This paragraph can be skipped if you do not use an external Wi-Fi adapter connected via USB. Quite often, the tire gives failures with its active use, so you should try to restart the device, turning it off and connecting it to another connector.

Cause 3: Antivirus

Antivirus programs are able to "hooligan" in the system are not worse than pests, with whom are designed to fight. Disable the protection and follow the steps described above, and specifically, restarting devices. If access to the network is restored, it is necessary to reinstall the antivirus or think about it to replace another product.

Cause 4: Battery Savings

The cause of the adapter malfunction can be the energy-saving laptop mode. In this case, the system reduces consumption or completely deprives the nutrition of the "extra" devices if the battery charge is approaching a certain value. You can exclude the adapter from this list in the Device Manager.

1. Open the start menu and go to the control panel.

   

2. We switch the viewing mode to "small badges" and open the "Device Manager".

   

3. We disclose a section with network adapters and find a device in the title of which appears "Wi-Fi" or "Wireless". Click on it with the right mouse button and go to "Properties".

   

4. We go to the power management tab and remove the check box specified on the screenshot. Thus, we forbidden the system to disable the device to save the battery.

   

5. For reliability, reboot the car.

Cause 5: Incorrect network settings

Incorrect network settings, or rather an IP address, affect the correctness of the functioning of this network itself. It is possible that these parameters have been changed due to failure or for other reasons.

1. In the "Control Panel" we go to the "Network and Shared Access Center" section.

   

2. Come on the link leading to the settings of the adapter parameters.

   

3. We find our wireless connection and go to its properties by pressing the right mouse button.

   

4. On the "Network" tab, select the "Internet version 4" protocol and press the "Properties" again.

   

5. We rearrange the switch to the manual IP position.

   

6. 6. Next, it is necessary to define the IP address of the router. You can do this by looking at the rear (bottom) cover of the device. Most often that

   192.168.1.1

   or

   192.168.0.1

   Therefore, in the IP field, you need to register the address that differs from the address of the router, but belonging to this network, for example, respectively

   192.168.1.3

   or

   192.168.0.3.

   When clicking on the "Subnet Mask", the data is inserted automatically. The "main gateway" should be specified the address of the router. The same data we introduce both in the "preferred DNS server" field. After entering the clamp approx.

   

7. 7. Restart the car.

Cause 6: Drivers

Drivers allow the operating system to define devices and interact with them. If the adapter software does not work properly for one reason or another, there will be no failures when accessing the network. The output here is obvious: you need to update or reinstall the driver.

Cause 7: Viruses

Since most of the reasons that cause limited access to Wi-Fi, software, do not exclude a viral attack. Malicious programs may be the main factor affecting such behavior of the system. They can change network settings, damage drivers and other ways to limit access to the network. You can correct the situation by studying the material available on the link below. Special attention should be paid to a way to appeal to special resources on the Internet. It is relevant to users without the experience of combating viruses.

Conclusion

The reasons described with this article are mostly eliminated quite simply. The exceptions make up options with the router settings or the removal of viruses, but this is written in detail in the instructions available according to the links. There is also the likelihood that the router or Wi-Fi adapter failed, so if no techniques helped to cope with the problem, it makes sense to contact the service center.
