Fixing the PC Cannot Connect to Wi-Fi Problem

We live in a digital world where you cannot afford to be disconnected from the Internet. A single day of being offline could see you miss a lot of information that is crucial to everyday life. Indeed, that is why it can be quite frustrating trying to connect your PC to the Internet only to be hit by the ‘No internet’ error. Such an error mainly happens when your PC either cannot connect to Wi-Fi or it connects but indicates that it has no internet. This post shows you how you can overcome such an error and use your PC to browse vital information on the Internet.
I once had this problem on my Windows 10 PC whereby it kept showing the error ‘Windows was unable to connect to RICNET.’ RICNET is the Wi-Fi name in my home. This is a PC that I had connected before to the network and so it was baffling that it could not connect to the same Wi-Fi after a simple act such as a Windows update. Luckily, my solution to the problem involved simply renewing the IP address. Here is how to go about doing so.

Release & Renew IP Address

When your PC connects to Wi-Fi, it is normally assigned an IP address. This IP address is required for you to connect to the Internet. The assignment of an IP address is usually done by what many simply call the DHCP server. Its actual full name is Dynamic Host Configuration Protocol. The DHCP server does Internet leasing to its client just the same way a physical property would be leased.
The IP address remains the same for quite an extended period of time, after which it gets to a period where DHCP releases and renews your IP address so that you can continue enjoying the Internet. This is a time when you are assigned a short-term DHCP and your connection to the Internet may be in serious jeopardy.
Your device is supposed to automatically renew its DHCP lease once the one it is using expires. However, if that doesn’t happen, you could always do so manually. If you are using the Windows 10 operating system, the following steps will take you through the manual release and renewal of your IP Address.
Step 1: Open the Run dialogue. To do so, simultaneously press the Windows and R key
Step 2: In the opened dialogue box, type CMD and press Enter key
Step 3: The above step opens the command prompt (the black screen that you are currently seeing). Into it type the command ‘ipconfig/release’ and press the Enter key as shown below

When you input the above command, you will realize that your Wi-Fi connection is still limited. Proceed to the next step to get your Internet back.
Step 4: Input the command ‘ipconfig/renew’ and press the Enter key

The two commands automatically reassign a new IP address to your machine and your Internet connection should be good to go. If you still encounter some form of error as you try to release and renew your DHCP assigned IP address, you should consider whether the network card drivers are up to date or outdated.
If you made a major Windows update or change in the OS version, then updating the drivers should be your next course of action. Here is how to go about it.

Update the Network Drivers

•    Press the Windows + X keys simultaneously
•    Locate Device Manager from the list of items that pops up
•    Choosing Device Manager sends you to the next page where you will see a number of devices on the PC
•    Locate the icon labeled “Network adapters” and double-click on it to expand
•    Spot the appropriate network driver as shown in the diagram below

•    Right-click on it, then choose the ‘Update driver’ option

•    Windows will scan for any available update and install it

If the problem persists, then it may be time to pay the router a visit. For those of you connected to the organization’s network, this is the point where you get to talk to your IT technician about the issue. This is because the following steps involve accessing the router, which in most cases it is only them that have that kind of access.
If you are lucky enough to have easy access to the router, then you can move on to the next steps to deal with your ‘PC cannot connect to Wi-Fi’ problem.

Restart the Wireless Router

The solution to your ‘PC cannot connect to Wi-Fi’ problem could be as simple as restarting the wireless router. It goes without saying that this is a solution which you can only implement if you have access to the router.
To restart your wireless router:
•    Unplug the router from its source of power (avoid just turning it off)
•    Give it a couple of seconds before plugging it back into power
•    Let the router slowly turn on
Through such simple steps of restarting the router, major Internet connection issues could get resolved. If your PC eventually manages to connect to Wi-Fi, you will have saved yourself the need to go a further step of resetting the modem to remove its password configuration. Unfortunately, some people have had to reach this step. It is as shown below.

Remove the Security Feature on the Wireless Router

If you are finding it hard to connect to your wireless router using its username and password, try to disable this security feature from the router. Different types of routers have different steps that you can follow to disable the security settings. But generally, the steps involve logging into the router, then accessing its wireless settings page from where the required adjustments will be made.
While on the wireless settings page, locate the part labeled ‘Security Options’ and select ‘None’. This may at other times be labeled as ‘Disable’. Whichever wording is used, selecting this option simply means that your wireless router will have no password. It is expected that your laptop should be able to connect to this password-free wireless connection. If you do manage to connect, then the problem may have been to do with security settings. Change the login credentials to something that you know.
